<i>Introduction</i>. Intestinal-type adenocarcinoma of the sinonasal tract is very rare and is responsible for less than 4% of tumours of the sinuses.  Craniofacial resection has been the mainstay of treatment for many years; however, techniques for endoscopic resection are constantly being developed.
<i>Discussion</i>. The use of transnasal endoscopic resection (TER) and topical chemotherapy applications as an alternative to cranio-facial resection (CFR) is discussed.  TER offers advantages over CFR in terms of fewer intra-operative complications and an improved cosmetic outcome.  Survival and metastatic rates are similar between both procedures.  Patients with locally invasive tumours are better managed with CFR.  Topical applications of 5-Fluorouracil has been shown to be effective in increasing survival in patients with sino-nasal malignancy.
<i>Conclusion</i>. Trans-nasal endoscopic resection and topical 5-Fluorouracil could potentially offer an acceptable alternative treatment to the standard of cranio-facial resection.  This should be investigated in trials with a longer followup period than this paper in order to directly compare the two treatment modalities.

Endoscopic Resection and Topical 5-Fluorouracil as an Alternative Treatment to Craniofacial Resection for the Management of Primary Intestinal-Type Sinonasal Adenocarcinoma

Blunt traumatic diaphragmatic rupture (BTDR) is a life-threatening condition with an incidence from 0,8%–1,6% in blunt trauma, mostly located on the left side. The main  prognostic factors are severe side injuries and the delay of diagnosis. We present a rare case of a 68-year-old female, with an isolated right diaphragm rupture. The diagnosis was done with a delay of 4 days by thoracic radiographs, which showed a  herniation of small bowel into the right thoracic cavity. A reposition of the small bowel and a closure of the diaphragmatic defect by running suture were carried out 
laparoscopicly. Although large prospective studies concerning the outcome of laparoscopic approach to right BTDR are still missing, we could show, that laparoscopy can be performed safely in right traumatic diaphragm rupture.

Laparoscopic Treatment of a Rare Right Diaphragmatic Rupture with Small Bowel Herniation after Blunt Thoracic Trauma

<i>Objective</i>. To estimate if there is a relationship between the results of tests of neurocognition and performance on a laparoscopic surgery simulator. <i>Methods and Materials</i>. Twenty participants with no prior laparoscopic experience had baseline cognitive tests administered (Trail Making Test, Part A and B (TMT-A and TMT-B), Grooved Peg Board Test, Symbol Digit Modalities Test, Symbol Digit Recall Test, and Stroop Interference Test), completed a demographic questionnaire, and then performed laparoscopy using a simulator. We correlated the results of cognitive tests with laparoscopic surgical performance. <i>Results</i>. One cognitive test sensitive to frontal lobe function, TMT-A, significantly correlated with laparoscopic surgical performance on the simulator (correlation coefficient of 0.534 with <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mi>P</mml:mi><mml:mo>&lt;</mml:mo><mml:mn>.05</mml:mn></mml:mrow></mml:math>).  However, the correlation between performance and other cognitive tests (TMT-B, Grooved Peg Board Test, Symbol Digit Modalities Test, Symbol Digit Recall Test, and Stroop Interference Test) was not statistically significant. 
 <i>Conclusion</i>. Laparoscopic performance may be related to measures of frontal lobe function. Neurocognitive tests may predict motor skills abilities and performance on laparoscopic simulator.

The Relationship between Tests of Neurocognition and Performance on a Laparoscopic Simulator

<i>Objectives</i>. Multiple technical difficulties are encountered when a multidisciplinary team of subspecialists begins a minimally-invasive fetal cardiac interventional program. We describe the learning curve. <i>Study Design</i>. Ten pregnant sheep underwent ultrasound-guided balloon valvuloplasty of the aortic valve. Team members and their roles remained constant through the trial. The time between needle insertion and entrance of the left ventricle at the aortic root was recorded. <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mi>F</mml:mi></mml:math>-test was used to assess significance (<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mi>P</mml:mi><mml:mo>≤</mml:mo><mml:mn>.05</mml:mn></mml:mrow></mml:math>). <i>Results</i>. The time required to accurately position the needle tip at the aortic root decreased significantly over the course of the trial, from 12 minutes with the first attempt to one minute with the last (<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mi>P</mml:mi><mml:mo>=</mml:mo><mml:mn>.003</mml:mn></mml:mrow></mml:math>). <i>Conclusion</i>. A significant learning curve is encountered when a multidisciplinary team begins a minimally-invasive fetal cardiac intervention program. However, technical proficiency can be achieved with practice. Institutions interested in developing such a program should consider practice in an animal model before proceeding to the human fetus.

</svg>). The uterus was hitched to the anterior abdominal.wall by either a single suture in the fundus or by sutures through the round ligaments. <i  >Results</i>. The uterine hitch technique was successfully accomplished in all procedures. It was performed in less than 5 minutes in all cases. It obviated the need for vaginal manipulation. An extra port for retraction could be avoided. There were no intraoperative complications. <i  >Conclusion</i>. A practical, cheap and reproducible method for uterine manipulation, during pelvic oncologic surgery is described. It improves the stability of the uterus and also obviates the need for keeping an additional assistant for vaginal manipulation in any of the procedures.

A Novel Technique of Uterine Manipulation in Laparoscopic Pelvic Oncosurgical Procedures: “The Uterine Hitch Technique”

<i>Background</i>. The laparoscopic cholecystectomy is a perfectly codified surgical procedure. The development of recent innovative and experimental surgical techniques Natural Orifice transluminal endoscopic surger (N.O.T.E.S.) which reduces the abdominal wall trauma leads us to develop a combined procedure of a standard dissection using miniaturised instruments already existing on the market (3 and 5&#x2009;mm wide) and a gall bladder removal through a short gastrotomy Natural Orifice Specimen Extraction (N.O.S.E.). <i>Methods</i>. Our objective was to evaluate the safety, the feasibility, and the reproducibility of our new approach. After reviewing existing products on the market and a feasibility study, we put in place a protocol in our structure for patients on whom the procedure was performed. We carried out a gall bladder removal by a short gastrotomy, located on the anterior gastric wall, which then reduced the abdominal wall trauma and allowed them to resume normal physical activity quickly without risk of trocar site hernia. <i>Results</i>. We performed the procedure described in this paper on 63 patients, between April 2008 and July 2009. There were 14 men and 49 women with an average age of 46.8 years (ranging from 28 to 77) and an average BMI of 27.2. 30 patients had at least one gallstone larger than 10&#x2009;mm. There was no postoperative gastric or abdominal wall complication and a fast recovery for all the patients in our study. <i>Conclusions</i>. This procedure is feasible, reproducible, with good results and minimal abdominal wall trauma. It is also safer than N.O.T.E.S. and endoscopic clipping and recovery, allowing normal physical activity, fast and, without risk of incisional hernia.
