Stability Outcomes following Computer-Assisted ACL Reconstruction Thu, 26 Mar 2015 12:57:54 +0000 Purpose. The purpose of this study was to determine whether intraoperative prereconstruction stability measurements and/or patient characteristics were associated with final knee stability after computer-assisted ACL reconstruction. Methods. This was a retrospective review of all patients who underwent computer-assisted single-bundle ACL reconstruction by a single surgeon. Prereconstruction intraoperative stability measurements were correlated with patient characteristics and postreconstruction stability measurements. 143 patients were included (87 male and 56 female). Average age was 29.8 years (SD ± 11.8). Results. Females were found to have significantly more pre- and postreconstruction internal rotation than males (P < 0.001 and P = 0.001, resp.). Patients with additional intra-articular injuries demonstrated more prereconstruction anterior instability than patients with isolated ACL tears (P < 0.001). After reconstruction, these patients also had higher residual anterior translation (P = 0.01). Among all patients with ACL reconstructions, the percent of correction of anterior translation was found to be significantly higher than the percent of correction for internal or external rotation (P < 0.001). Conclusion. Anterior translation was corrected the most using a single-bundle ACL reconstruction. Females had higher pre- and postoperative internal rotation. Patients with additional injuries had greater original anterior translation and less operative correction of anterior translation compared to patients with isolated ACL tears. Melissa A.

Two Ports Laparoscopic Inguinal Hernia Repair in Children Mon, 16 Feb 2015 09:30:32 +0000 Introduction. Several laparoscopic treatment techniques were designed for improving the outcome over the last decade. The various techniques differ in their approach to the inguinal internal ring, suturing and knotting techniques, number of ports used in the procedures, and mode of dissection of the hernia sac. Patients and Surgical Technique. 90 children were subjected to surgery and they undergone two-port laparoscopic repair of inguinal hernia in children. Technique feasibility in relation to other modalities of repair was the aim of this work. 90 children including 75 males and 15 females underwent surgery. Hernia in 55 cases was right-sided and in 15 left-sided. Two patients had recurrent hernia following open hernia repair. 70 (77.7%) cases were suffering unilateral hernia and 20 (22.2%) patients had bilateral hernia. Out of the 20 cases 5 cases were diagnosed by laparoscope (25%). The patients’ median age was 18 months. The mean operative time for unilateral repairs was 15 to 20 minutes and bilateral was 21 to 30 minutes. There was no conversion. The complications were as follows: one case was recurrent right inguinal hernia and the second was stitch sinus. Discussion. The results confirm the safety and efficacy of two ports laparoscopic hernia repair in congenital inguinal hernia in relation to other modalities of treatment. Medhat M.

Laparoscopic Watson Fundoplication Is Effective and Durable in Children with Gastrooesophageal Reflux Wed, 31 Dec 2014 11:29:50 +0000 Gastroesophageal reflux (GOR) affects 2–8% of children over 3 years of age and is associated with significant morbidity. The disorder is particularly critical in neurologically impaired children, who have a high risk of aspiration. Traditionally, the surgical antireflux procedure of choice has been Nissen’s operation. However, this technique has a significant incidence of mechanical complications and has a reoperation rate of approximately 7%, leading to the development of alternative approaches. Watson’s technique of partial anterior fundoplication has been shown to achieve long-lasting reflux control in adults with few mechanical complications, but there is limited data in the paediatric population. We present here short- and long-term outcomes of laparoscopic Watson fundoplication in a series of 76 children and infants, 34% of whom had a degree of neurological impairment including severe cerebral palsy and hypoxic brain injury. The overall complication rate was 27.6%, of which only 1 was classified as major. To date, we have not recorded any incidences of perforation and no revisions. In our experience, Watson’s laparoscopic partial fundoplication can be performed with minimal complications and with durable results, not least in neurologically compromised children, making it a viable alternative to the Nissen procedure in paediatric surgery.

Transvaginal Appendectomy: A Systematic Review Mon, 29 Dec 2014 00:10:18 +0000 Background. Natural orifice transluminal endoscopic surgery (NOTES) is a new approach that allows minimal invasive surgery through the mouth, anus, or vagina. Objective. To summarize the recent clinical appraisal, feasibility, complications, and limitations of transvaginal appendectomy for humans and outline the techniques. Data Sources. PubMed/MEDLINE, Cochrane, Google-Scholar, EBSCO, and congress abstracts, were searched. Study Selection. All related reports were included, irrespective of age, region, race, obesity, comorbidities or history of previous surgery. No restrictions were made in terms of language, country or journal. Main Outcome Measures. Patient selection criteria, surgical techniques, and results. Results. There were total 112 transvaginal appendectomies. All the selected patients had uncomplicated appendicitis and there were no morbidly obese patients. There was no standard surgical technique for transvaginal appendectomy. Mean operating time was 53.3 minutes (25–130 minutes). Conversion and complication rates were 3.6% and 8.2%, respectively. Mean length of hospital stay was 1.9 days. Limitations. There are a limited number of comparative studies and an absence of randomized studies. Conclusions. For now, nonmorbidly obese females with noncomplicated appendicitis can be a candidate for transvaginal appendectomy. It may decrease postoperative pain and enable the return to normal life and work off time. More comparative studies including subgroups are necessary.

Antimullerian Hormone Changes after Laparoscopic Ovarian Cystectomy for Endometrioma Compared with the Nonovarian Conditions Sun, 14 Dec 2014 12:14:19 +0000 Laparoscopic ovarian cystectomy is recommended for surgical procedure of endometrioma. The negative impact on ovarian reserve following removal had been documented. Little evidence had been reported for nonovarian originated effects. Objective. To evaluate the impact of laparoscopic ovarian cystectomy for endometrioma on ovarian reserve, measured by serum antimullerian hormone (AMH), compared to nonovarian pelvic surgery. Materials and Methods. A prospective study was conducted. Women who underwent laparoscopic ovarian cystectomy (LOC) and laparoscopic nonovarian pelvic surgery (NOS) were recruited and followed up through 6 months. Clinical baseline data and AMH were evaluated. Results. 39 and 38 participants were enrolled in LOC and NOS groups, respectively. Baseline characteristics (age, weight, BMI, and height) and preoperative AMH level between 2 groups were not statistically different. After surgery, AMH of both groups decreased since the first week, at 1 month and at 3 months. However, as compared to the LOC group at 6 months after operation, the mean AMH of the NOS group had regained its value with a highly significant difference. Conclusion. This study demonstrated the negative impact of nonovarian or indirect effects of laparoscopic surgery to ovarian reserve. The possible mechanisms are necessary for more investigations.

To find out the changing trends in indications for use of laparoscopy for diagnostic or operative procedures in gynaecology. Methods. This was a clinical audit of 417 women who underwent laparoscopic procedures over a period of 8 years from January 2005 to December 2012 in the Department of Obstetrics and Gynaecology at a tertiary care centre in Delhi. Results. A total of 417 diagnostic and operative laparoscopic procedures were performed during the period from January 2005 to December 2012. Out of 417 women, 13 women were excluded from the study due to inadequate data. 208 (51.4%) women had only diagnostic laparoscopy whereas 196 (48.6%) patients had operative laparoscopy after the initial diagnostic procedure. Change in trend of diagnostic versus operative procedures was observed from 2005 to 2012. There was increase in operative procedures from 10 (37.03%) women in 2005 as compared to 51 (73.91%) in 2012. The main indication for laparoscopy was infertility throughout the study period (61.38%), followed by chronic pelvic pain (CPP) (11.38%) and abnormal uterine bleeding (AUB) (9.4%). Conclusion. Over the years, there has been a rise in the rate of operative laparoscopy. Though the indications for laparoscopy have remained almost similar during the years, laparoscopy for diagnosis and treatment of CPP and AUB has now increased.

Laparoscopic versus Open Surgery for Colorectal Cancer: A Retrospective Analysis of 163 Patients in a Single Institution Sun, 23 Nov 2014 14:28:13 +0000 Background. The present study aimed to compare the clinical outcomes of laparoscopic versus open surgery for colorectal cancers. Materials and Methods. The medical records from a total of 163 patients who underwent surgery for colorectal cancers were retrospectively analyzed. Patient’s demographic data, operative details and postoperative early outcomes, outpatient follow-up, pathologic results, and stages of the cancer were reviewed from the database. Results. The patients who underwent laparoscopic surgery showed significant advantages due to the minimally invasive nature of the surgery compared with those who underwent open surgery, namely, less blood loss, faster postoperative recovery, and shorter postoperative hospital stay (). However, laparoscopic surgery for colorectal cancer resulted in a longer operative time compared with open surgery (). There were no statistically significant differences between groups for medical complications (). Open surgery resulted in more incisional infections and postoperative ileus compared with laparoscopic surgery (). There were no differences in the pathologic parameters between two groups (). Conclusions. These findings indicated that laparoscopic surgery for colorectal cancer had the clear advantages of a minimally invasive surgery and relative disadvantage with longer surgery time and exhibited similar pathologic parameters compared with open surgery.

The Arrowhead Ministernotomy with Rigid Sternal Plate Fixation: A Minimally Invasive Approach for Surgery of the Ascending Aorta and Aortic Root Tue, 18 Nov 2014 09:09:01 +0000 Background. Ministernotomy incisions have been increasingly used in a variety of settings. We describe a novel approach to ministernotomy using arrowhead incision and rigid sternal fixation with a standard sternal plating system. Methods. A small, midline, vertical incision is made from the midportion of the manubrium to a point just above the 4th intercostal mark. The sternum is opened in the shape of an inverted T using two oblique horizontal incisions from the midline to the sternal edges. At the time of chest closure, the three bony segments are aligned and approximated, and titanium plates (Sternalock, Jacksonville, Florida) are used to fix the body of the sternum back together. Results. This case series includes 11 patients who underwent arrowhead ministernotomy with rigid sternal plate fixation for aortic surgery. The procedures performed were axillary cannulation (), aortic root replacement (), valve sparing root replacement (), and replacement of the ascending aorta () and/or hemiarch (). Thirty-day mortality was 0%; there were no conversions, strokes, or sternal wound infections. Conclusions. Arrowhead ministernotomy with rigid sternal plate fixation is an adequate minimally invasive approach for surgery of the ascending aorta and aortic root. Mark J.

Ureteral Stenting after Uncomplicated Ureteroscopy for Distal Ureteral Stones: A Randomized, Controlled Trial Sun, 09 Nov 2014 09:43:34 +0000 Objectives. We compared outcome and complications after uncomplicated ureteroscopic treatment of distal ureteral calculi with or without the use of ureteral stents. Materials and Methods. 117 patients, prospectively divided into three groups to receive a double j stent (group 1, 42 patients), ureteral stent (group 2, 37 patients), or no stent (group 3, 38 patients), underwent ureteroscopic treatment of distal ureteral calculi. Stone characteristics, operative time, postoperative pain, lower urinary tract symptoms (LUTS), analgesia need, rehospitalization, stone-free rate, and late postoperative complications were all studied. Results. There were no significant differences in preoperative data. There was no significant difference between the three groups regarding hematuria, fever, flank pain, urinary tract infection, and rehospitalisation. At 48 hours and 1 week, frequency/urgency and dysuria were significantly less in the nonstented group. When comparing group 1 and group 3, patients with double j stents had statistically significantly more bladder pain (), frequency/urgency (), dysuria (), and need of analgesics (). All patients who underwent imaging postoperatively were without evidence of obstruction or ureteral stricture. Conclusions. Uncomplicated ureteroscopy for distal ureteral calculi without intraoperative ureteral dilation can safely be performed without placement of a ureteral stent. Y. El Harrech, N. Abakka, J.

In Silico Investigation of a Surgical Interface for Remote Control of Modular Miniature Robots in Minimally Invasive Surgery Tue, 09 Sep 2014 09:37:22 +0000 Aim. Modular mini-robots can be used in novel minimally invasive surgery techniques like natural orifice transluminal endoscopic surgery (NOTES) and laparoendoscopic single site (LESS) surgery. The control of these miniature assistants is complicated. The aim of this study is the in silico investigation of a remote controlling interface for modular miniature robots which can be used in minimally invasive surgery. Methods. The conceptual controlling system was developed, programmed, and simulated using professional robotics simulation software. Three different modes of control were programmed. The remote controlling surgical interface was virtually designed as a high scale representation of the respective modular mini-robot, therefore a modular controlling system itself. Results. With the proposed modular controlling system the user could easily identify the conformation of the modular mini-robot and adequately modify it as needed. The arrangement of each module was always known. The in silico investigation gave useful information regarding the controlling mode, the adequate speed of rearrangements, and the number of modules needed for efficient working tasks. Conclusions. The proposed conceptual model may promote the research and development of more sophisticated modular controlling systems. Modular surgical interfaces may improve the handling and the dexterity of modular miniature robots during minimally invasive procedures.

Endovascular Recanalization for Chronic Symptomatic Intracranial Vertebral Artery Total Occlusion Wed, 03 Sep 2014 10:38:16 +0000 Purpose. The outcome of recanalization in patients with chronic symptomatic intracranial vertebral artery (ICVA) total occlusion is poor. This paper reports the technical feasibility and long-term outcome of ICVA stenting in patients with chronic symptomatic total occlusion. Methods. Retrospective review of our prospectively maintained intracranial intervention database to identify patients with symptomatic total occlusion of ICVA with revascularization attempted >1 month after index ischemic event. Results. Eight patients (mean age 58 years) were identified. One had stroke and 7 had recurrent transient ischemic attacks. Four had bilateral ICVA total occlusion and 4 had unilateral ICVA total occlusion with severe stenosis contralaterally. Seven of 8 patients underwent endovascular recanalization, which was achieved in 6. Periprocedural complications included cerebellum hemorrhage, arterial dissection, perforation, and subacute in-stent thrombosis which occurred in 3 patients. One patient died of cerebellum hemorrhage. The other patients improved clinically after endovascular therapy. Conclusions. Stent-supported recanalization of ICVA total occlusion is technically feasible, and may become a viable treatment option in selected patients.

Operative Outcome and Patient Satisfaction in Early and Delayed Laparoscopic Cholecystectomy for Acute Cholecystitis Thu, 14 Aug 2014 00:00:00 +0000 Introduction. Early laparoscopic cholecystectomy is usually associated with reduced hospital stay, sick leave, and health care expenditures. Early diagnosis and treatment of acute cholecystitis reduce both mortality and morbidity and the accurate diagnosis requires specific diagnostic criteria of clinical data and imaging studies. Objectives. To compare early versus delayed laparoscopic cholecystectomy regarding the operative outcome and patient satisfaction. Patients and Methods. Patients with acute cholecystitis were divided into two groups, early (A) and delayed (B) cholecystectomy. Diagnosis of acute cholecystitis was confirmed by clinical examination, laboratory data, and ultrasound study. The primary end point was operative and postoperative outcome and the secondary was patient’s satisfaction. Results. The number of readmissions in delayed treatment group B was three times in 10% of patients, twice in 23.3%, and once in 66.7% while the number of readmissions was once only in patients in group A and the mean total hospital stays were higher in group B than in group A. The overall patient’s satisfaction was in group A compared with in group B. Conclusion. Early laparoscopic cholecystectomy resulted in significant reduction in length of hospital stay and accepted rate of operative complications and conversion rates when compared with delayed techniques.

Tue, 12 Aug 2014 09:22:53 +0000 Objective. The aim of the study is to evaluate adenomyosis in patients undergoing surgery for different type of endometriosis. It is an observational study including women with preoperative ultrasound diagnosis of adenomyosis. Demographic data and symptoms were recorded (age, body mass index, parity, history of previous surgery, dysmenorrhea, dyspareunia, dyschezia, dysuria, and abnormal uterine bleeding). Moreover a particular endometrial shape “question mark sign” linked to the presence of adenomyosis was assessed. Results. From 217 patients with ultrasound diagnosis of adenomyosis, we found 73 with ovarian histological confirmation of endometriosis, 92 with deep infiltrating endometriosis, and 52 patients who underwent surgery for infertility. Women with adenomyosis alone represented the oldest group of patients ( years, ). Deep endometriosis patients were nulliparous more frequently (), had history of previous surgery (), and complained of more intense pain symptoms than other groups. Adenomyosis alone was significantly associated with abnormal uterine bleeding (). The question mark sign was found to be strongly related to posterior deep infiltrating endometriosis (). Conclusion. Our study confirmed the strong relationship between adenomyosis and endometriosis and evaluated demographic aspects and symptoms in patients affected by different type of endometriosis.

Reducing the Cost of Laparoscopy: Reusable versus Disposable Laparoscopic Instruments Tue, 22 Jul 2014 10:19:20 +0000 Cost-effectiveness in health care management is critical. The situation in debt-stricken Greece is further aggravated by the financial crisis and constant National Health System expense cut-downs. In an effort to minimize the cost of laparoscopy, our department introduced reusable laparoscopic instruments in December 2011. The aim of this study was to assess potential cost reduction of laparoscopic operations in the field of general surgery. Hospital records, invoice lists, and operative notes between January 2012 and December 2013, were retrospectively reviewed and data were collected on laparoscopic procedures, instrument failures, and replacement needs. Initial acquisition cost of 5 basic instrument sets was €21,422. Over the following 24 months, they were used in 623 operations, with a total maintenance cost of €11,487. Based on an average retail price of €490 per set, projected cost with disposable instruments would amount to €305,270, creating savings of €272,361 over the two-year period under study. Despite the seemingly high purchase price, each set amortized its acquisition cost after only 9 procedures and instrument cost depreciated to less than €55 per case. Disposable instruments cost 9 times more than reusable ones, and their high price would almost equal the total hospital reimbursement by social security funds for many common laparoscopic procedures.

Novel Axillary Approach for Brachial Plexus in Robotic Surgery: A Cadaveric Experiment Mon, 21 Jul 2014 11:49:24 +0000 Brachial plexus surgery using the da Vinci surgical robot is a new procedure. Although the supraclavicular approach is a well known described and used procedure for robotic surgery, axillary approach was unknown for brachial plexus surgery. A cadaveric study was planned to evaluate the robotic axillary approach for brachial plexus surgery. Our results showed that robotic surgery is a very useful method and should be used routinely for brachial plexus surgery and particularly for thoracic outlet syndrome. However, we emphasize that new instruments should be designed and further studies are needed to evaluate in vivo results. Cihangir Tetik and Metin Uzun Copyright © 2014 Cihangir Tetik and Metin Uzun.

Complications of Minimally Invasive, Tubular Access Surgery for Cervical, Thoracic, and Lumbar Surgery Mon, 07 Jul 2014 00:00:00 +0000 The object of the study was to review the author’s large series of minimally invasive spine surgeries for complication rates. The author reviewed a personal operative database for minimally access spine surgeries done through nonexpandable tubular retractors for extradural, nonfusion procedures. Consecutive cases () were reviewed for complications. There were no wound infections. Durotomy occurred in 33 cases (2.7% overall or 3.4% of lumbar cases). There were no external or symptomatic internal cerebrospinal fluid leaks or pseudomeningoceles requiring additional treatment. The only motor injuries were 3 C5 root palsies, 2 of which resolved. Minimally invasive spine surgery performed through tubular retractors can result in a low wound infection rate when compared to open surgery. Durotomy is no more common than open procedures and does not often result in the need for secondary procedures. New neurologic deficits are uncommon, with most observed at the C5 root. Minimally invasive spine surgery, even without benefits such as less pain or shorter hospital stays, can result in considerably lower complication rates than open surgery. Donald A.

Prospective Observational Study of Single-Site Multiport Per-umbilical Laparoscopic Endosurgery versus Conventional Multiport Laparoscopic Cholecystectomy: Critical Appraisal of a Unique Umbilical Approach Wed, 30 Apr 2014 07:24:12 +0000 Purpose. This prospective observational study compares an innovative approach of Single-Site Multi-Port Per-umbilical Laparoscopic Endo-surgery (SSMPPLE) cholecystectomy with the gold standard—Conventional Multi-port Laparoscopic Cholecystectomy (CMLC)—to assess the feasibility and efficacy of the former. Methods. In all, 646 patients were studied. SSMPPLE cholecystectomy utilized three ports inserted through three independent mini-incisions at the umbilicus. Only the day-to-day rigid laparoscopic instruments were used in all cases. The SSMPPLE cholecystectomy group had 320 patients and the CMLC group had 326 patients. The outcomes were statistically compared. Results. SSMPPLE cholecystectomy had average operative time of 43.8 min and blood loss of 9.4 mL. Their duration of hospitalization was 1.3 days (range, 1–5). Six patients (1.9%) of this group were converted to CMLC. Eleven patients had controlled gallbladder perforations at dissection. The Visual Analogue Scores for pain on postoperative days 0 and 7, the operative time, and the scar grades were significantly better for SSMPPLE than CMLC. However, umbilical sepsis and seroma outcomes were similar. We had no bile-duct injuries or port-site hernias in this study. Conclusion. SSMPPLE cholecystectomy approach complies with the principles of laparoscopic triangulation; it seems feasible and safe method of minimally invasive cholecystectomy. Overall, it has a potential to emerge as an economically viable alternative to single-port surgery.

A New Proposal for Learning Curve of TEP Inguinal Hernia Repair: Ability to Complete Operation Endoscopically as a First Phase of Learning Curve Wed, 23 Apr 2014 11:39:29 +0000 Background. The exact nature of learning curve of totally extraperitoneal inguinal hernia and the number required to master this technique remain controversial. Patients and Methods. We present a retrospective review of a single surgeon experience on patients who underwent totally extraperitoneal inguinal hernia repair. Results. There were 42 hernias (22 left- and 20 right-sided) in 39 patients with a mean age of years. Indirect, direct, and combined hernias were present in 18, 12, and 12 cases, respectively. The mean operative time was minutes. Peritoneal injury occurred in 9 cases (21.4%). Conversion to open surgery was necessitated in 7 cases (16.7%). After grouping of all patients into two groups as cases between 1–21 and 22–42, it was seen that the majority of peritoneal injuries (7 out of 9, 77.8%, ) and all conversions () occurred in the first 21 cases. Conclusions. Learning curve of totally extraperitoneal inguinal hernia repair can be divided into two consequent steps: immediate and late. At least 20 operations are required for gaining anatomical knowledge and surgical pitfalls based on the ability to perform this operation without conversion during immediate phase.

Transforaminal Approach in Thoracal Disc Pathologies: Transforaminal Microdiscectomy Technique Tue, 15 Apr 2014 11:36:09 +0000 Objective. Many surgical approaches have been defined and implemented in the last few decades for thoracic disc herniations. The endoscopic foraminal approach in foraminal, lateral, and far lateral disc hernias is a contemporary minimal invasive approach. This study was performed to show that the approach is possible using the microscope without an endoscope, and even the intervention on the discs within the spinal canal is possible by having access through the foramen. Methods. Forty-two cases with disc hernias in the medial of the pedicle were included in this study; surgeries were performed with transforaminal approach and microsurgically. Extraforaminal disc hernias were not included in the study. Access was made through the Kambin triangle, foramen was enlarged, and spinal canal was entered. Results. The procedure took 65 minutes in the average, and the mean bleeding amount was about 100cc. They were mobilized within the same day postoperatively. No complications were seen. Follow-up periods range between 5 and 84 months, and the mean follow-up period is 30.2 months. Conclusion. Transforaminal microdiscectomy is a method that can be performed in any clinic with standard spinal surgery equipment. It does not require additional equipment or high costs.

Prospective Comparison of Nonnarcotic versus Narcotic Outpatient Oral Analgesic Use after Laparoscopic Appendectomy and Early Discharge Mon, 14 Apr 2014 09:35:44 +0000 Purpose. To compare narcotic versus nonnarcotic outpatient oral pain management after pediatric laparoscopic appendectomy. Methods. In a prospective study from July 1, 2010, to March 30, 2011, children undergoing laparoscopic appendectomy on a rapid discharge protocol were treated with either nonnarcotic or narcotic postoperative oral analgesia. Two surgeons in a four-person faculty group employed the nonnarcotic regimen, while the other two used narcotics. Days of medication use, time needed for return to normal activity, and satisfaction rate with the pain control method were collected. Student’s t-test was used for statistical analysis. Results. A total of 207 consecutive children underwent appendectomy for acute, nonperforated appendicitis or planned interval appendectomy. The age and time to discharge were equivalent between the nonnarcotic () and narcotic () groups. Both had an equivalent number of medication days and similar times of return to normal activity. Ninety-seven percent of the parents of children in the nonnarcotic group stated that the pain was controlled by the prescribed medication, compared to 90 percent in the narcotic group (). Conclusion. This study indicates that after non-complicated pediatric laparoscopic appendectomy, nonnarcotic is equivalent to narcoticbased therapy for outpatient oral analgesia, with higher parental satisfaction.

Video-Assisted Thoracic Surgery for Tubercular Spondylitis Thu, 03 Apr 2014 13:36:41 +0000 The present study evaluated the outcome of video-assisted thoracic surgery (VATS) in 9 patients (males = 6, females = 3) with clinico-radiological diagnosis of tubercular spondylitis of the dorsal spine. The mean duration of surgery was 140.88 ± 20.09 minutes, mean blood was 417.77 ± 190.90 mL, and mean duration of postoperative hospital stay was 5.77 ± 0.97 days, Seven patients had a preoperative Grade A neurological involvement, while at the time of final followup the only deficit was Grade D power in 2 patients. In patients without bone graft placement (n = 6), average increase in Kyphosis angle was 16°, while in patients with bone graft placement (n = 3) the deformity remained stationary. At the time of final follow up, fusion was achieved in all patients, the VAS score for back pain improved from a pretreatment score of 8.3 to 2, and the function assessment yielded excellent (n = 4) to good (n = 5) results. In two patients minithoracotomy had to be resorted due to extensive pleural adhesions (n = 1) or difficulty in placement of graft (n = 1). Videoassisted thoracoscopic surgery provides a safe and effective approach in the management of spinal tuberculosis. It has the advantages of decreased blood loss and post operative morbidity with minimal complications.

National Trends in the Adoption of Laparoscopic Cholecystectomy over 7 Years in the United States and Impact of Laparoscopic Approaches Stratified by Age Thu, 20 Mar 2014 06:50:32 +0000 Introduction. The aim of this study was to characterize national trends in adoption of laparoscopic cholecystectomy and determine differences in outcome based on type of surgery and patient age. Methods. Retrospective cross-sectional study of patients undergoing cholecystectomy. Trends in open versus laparoscopic cholecystectomy by age group and year were analyzed. Differences in outcomes including in-hospital mortality, complications, discharge disposition, length of stay (LOS), and cost are examined. Results. Between 1999 and 2006, 358,091 patients underwent cholecystectomy. In 1999, patients aged ≥80 years had the lowest rates of laparoscopic cholecystectomy, followed by those aged 65–79, 64–50, and 49–18 years (59.7%, 65.3%, 73.2%, and 83.5%, resp., ). Laparoscopic cholecystectomy was associated with improved clinical and economic outcomes across all age groups. Over the study period, there was a gradual increase in laparoscopic cholecystectomy performed among all age groups during each year, though elderly patients continued to lag significantly behind their younger counterparts in rates of laparoscopic cholecystectomy. Conclusion. This is the largest study to report trends in adoption of laparoscopic cholecystectomy in the US in patients stratified by age. Elderly patients are more likely to undergo open cholecystectomy. Laparoscopic cholecystectomy is associated with improved clinical outcomes. Anahita Dua, Abdul Aziz, Sapan S.

Laparoscopic Appendectomy in Children: Experience in a Single Centre in Chittagong, Bangladesh Tue, 11 Mar 2014 13:22:25 +0000 Background. Since the latter half of 1980s laparoscopy has become a well accepted modality in children in many surgical procedures including appendectomy. We present here the experience of laparoscopic appendectomy in children in a tertiary care hospital in Bangladesh.  Subjects & Methods. From October 7, 2005 to July 31, 2012, 1809 laparoscopic appendectomies were performed. Laparoscopy was performed in all the cases using 3 ports. For difficult and adherent cases submucosal appendectomy was performed. Feeding was allowed 6 h after surgery and the majority was discharged on the first postoperative day. The age, sex, operative techniques, operative findings, operative time, hospital stay, outcome, and complications were evaluated in this retrospective study. Results. Mean age was 8.17 ± 3.28 years and 69% were males. Fifteen percent were complicated appendicitis, 8 cases needed conversion, and 27 cases were done by submucosal technique. Mean operating time was 39.8 ± 14.2 minutes and mean postoperative hospital stay was 1.91 days. About 5% cases had postoperative complications including 4 intra-abdominal abscesses. Conclusions. Laparoscopic appendectomy is a safe procedure in children even in complicated cases. Md. Jafrul Hannan Copyright © 2014 Md. Jafrul Hannan. All rights reserved. Converting Potential Abdominal Hysterectomy to Vaginal One: Laparoscopic Assisted Vaginal Hysterectomy Wed, 05 Mar 2014 00:00:00 +0000 Background. The idea of laparoscopic assisted vaginal hysterectomy (LAVH) is to convert a potential abdominal hysterectomy to a vaginal one, thus decreasing associated morbidity and hastening recovery. We compared intraoperative and postoperative outcomes between LAVH and abdominal hysterectomy, to find out if LAVH achieves better clinical results compared with abdominal hysterectomy. Material and methods. A total of 48 women were enrolled in the study. Finally 17 patients underwent LAVH (cases) and 20 underwent abdominal hysterectomy (controls). All surgeries were performed by a set of gynecologists with more or less same level of surgical experience and expertise. Results.None of the patients in LAVH required conversion to laparotomy. Mean operating time was 30 minutes longer in LAVH group as compared to abdominal hysterectomy group (167.06 + 31.97 min versus 135.25 + 31.72 min; ). However, the mean blood loss in LAVH was 100 mL lesser than that in abdominal hysterectomy and the difference was found to be statistically significant (248.24 + 117.79 mL versus 340.00 + 119.86 mL; ). Another advantage of LAVH was significantly lower pain scores on second and third postoperative days. Overall complications and postoperative hospital stay were not significantly different between the two groups. Jyothi Shetty, Asha Shanbhag, and Deeksha Pandey Copyright © 2014 Jyothi Shetty et al.

Gastroesophageal reflux disease currently accounts for the majority of esophageal pathologies. This study is an attempt to help us tackle the diagnostic and therapeutic challenges of this disease. This study specifically focuses on patients in the urban Indian setup. Materials and Methods. This study was a prospective interventional study carried out at a teaching public hospital in Mumbai from May 2010 to September 2012. Fifty patients diagnosed with gastroesophageal reflux disease (confirmed by endoscopy and esophageal manometry) were chosen for the study. Results. Fifty patients were included in the study. Twenty patients showed symptomatic improvement after three months and were thus managed conservatively, while 30 patients did not show any improvement in symptoms and were eventually operated. Conclusion. We suggest that all patients diagnosed to have gastroesophageal reflux disease should be subjected to 3 months of conservative management. In case of no relief of symptoms, patients need to be subjected to surgery. Laparoscopic Toupet's fundoplication is an effective and feasible surgical treatment option for such patients, associated with minimal side effects. However, the long-term effects of this form of treatment still need to be evaluated further with a larger sample size and a longer followup.

Minimally Invasive Local Treatments for Bone and Pulmonary Metastases Tue, 11 Feb 2014 09:13:38 +0000 Surgery and chemotherapy have historically been the mainstay of treatment in patients with metastatic disease. However there are many alternative therapies available to relieve the symptoms and morbidity of metastases. In this paper, we review the role and highlight the advantages of minimally invasive techniques employed in patients with pulmonary and bone metastases. Meena Bedi, David M.

Standardization of Laparoscopic Pelvic Examination: A Proposal of a Novel System Mon, 30 Dec 2013 08:27:17 +0000 Objective. Laparoscopic pelvic assessment is often performed in a nonstandardized fashion depending on the surgeon’s discretion. Reporting anatomic findings is inconsistent and lesions in atypical locations may be missed. We propose a method for systematic pelvic assessment based on anatomical landmarks. Design. Retrospective analysis. Setting. Tertiary care academic medical center. Intervention. We applied this system to operative reports of 540 patients who underwent diagnostic or operative laparoscopy for unexplained infertility between 2006 and 2012. The pelvis was divided into 2 midline zones (zone I and II) and right and left lateral zones (zone III and IV). All reports were evaluated for the comprehensiveness of description with respect to normal findings or pathology for each zone. Results. Of 540 surgeries, all reports commented on the uterus, tubes, and ovaries (100%), but only 17% (, 95% CI: 13.8–20.2) commented on the dome of the bladder and the anterior cul-de-sac. 24% (, 95% CI: 20.4–27.6) commented on the posterior cul-de-sac, and 5% (, 95% CI: 3.2–6.8) commented on the pelvic sidewall. Overall, 6% (, 95% CI: 4–8) reported near complete documentation of the pelvic zones. Conclusion. Implementation of a systematic approach for laparoscopic pelvic examination will enhance the diagnostic accuracy and provide better communication between care providers. In the absence of pelvic pathology, we recommend a minimum of 6 photographs of the 6 pelvic zones. Mohamed A.

Endoscopic Transforaminal Thoracic Foraminotomy and Discectomy for the Treatment of Thoracic Disc Herniation Wed, 18 Dec 2013 18:28:06 +0000 Thoracic disc herniation is a relatively rare yet challenging-to-diagnose condition. Currently there is no universally accepted optimal surgical treatment for symptomatic thoracic disc herniation. Previously reported surgical approaches are often associated with high complication rates. Here we describe our minimally invasive technique of removing thoracic disc herniation, and report the primary results of a series of cases. Between January 2009 and March 2012, 13 patients with symptomatic thoracic disc herniation were treated with endoscopic thoracic foraminotomy and discectomy under local anesthesia. A bone shaver was used to undercut the facet and rib head for foraminotomy. Discectomy was achieved by using grasper, radiofrequency, and the Holmium-YAG laser. We analyzed the clinical outcomes of the patients using the visual analogue scale (VAS), MacNab classification, and Oswestry disability index (ODI). At the final follow up (mean: 17 months; range: 6–41 months), patient self-reported satisfactory rate was 76.9%. The mean VAS for mid back pain was improved from 9.1 to 4.2, and the mean ODI was improved from 61.0 to 43.8. One complication of postoperative spinal headache occurred during the surgery and the patient was successfully treated with epidural blood patch. No other complications were observed or reported during and after the surgery. Hong-Fei Nie and Kai-Xuan Liu Copyright © 2013 Hong-Fei Nie and Kai-Xuan Liu. All rights reserved.
