Mixed Adenoneuroendocrine Carcinoma Is a Rare but Important Tumour Found in the Oesophagus Wed, 03 Feb 2016 09:53:24 +0000 Mixed adenoneuroendocrine carcinoma (MANEC) is a rare tumour of the gastrointestinal tract that consists of a dual adenocarcinomatous and neuroendocrine differentiation, each component representing at least 30% of the tumour. We report a case of a 68-year-old man who presented with two-month history of postprandial pain and vomiting. Gastric endoscopy revealed a polypoid mass in the lower part of the oesophagus. In contrast to the majority of these tumours, this biopsy was immunohistochemically positive for chromogranin A, and synaptophysin and Ki-67 index was 50% and the tumour was diagnosed as poorly differentiated neuroendocrine carcinoma of the oesophagus. The patient underwent surgery and lower oesophagus resection was performed. Based on the histopathology and immunohistochemistry of the tumour in the oesophagogastrectomy specimen, a mixed adenoneuroendocrine carcinoma (MANEC) was diagnosed. The objective of this case report is to advocate for the focus on the MANEC diagnosis as such patients need to be referred to a centre of excellence with expertise in NET tumours, to have the correct diagnostic work-up, treatment, and secondary diagnostic procedures performed at progression, as this will have paramount influence of the choice of treatment.

Agenesis of the Gallbladder in Monozygotic Twin Sisters Tue, 26 Jan 2016 12:57:10 +0000 Agenesis of the gallbladder, a rare anomaly, is generally regarded as an organogenic failure. Several reports suggest that this congenital defect is inherited but that supposition remains controversial. We described agenesis of the gallbladder in identical twins. A 21-year-old female presented with a history of acute pain in the epigastrium and right hypochondrium. Various imaging modalities showed “gallbladder agenesis.” Moreover, her older identical twin sister had also no visualized gallbladder in imaging modalities. This case report strongly suggested that agenesis of the gallbladder would be caused by a genetic abnormality.

A Timely Intervention: Endoscopic Retrieval of a Swallowed Magnetized Activity Watch Tue, 19 Jan 2016 12:47:05 +0000 The accidental ingestion of a foreign object often presents a difficult scenario for the clinician. This includes not only the decision to retrieve the material but also the appropriate technique to use. We present the case of a young asymptomatic girl who swallowed a magnetic activity watch, which was then successfully retrieved with an endoscopic snare. To our knowledge, this is the first documented case of salvaging an operational watch from the stomach using an endoscopic technique. Jason S. Radowsky, Joseph S. Lee, and Andrew T.

Protein Loosing Enteropathy Secondary to Strongyloidiasis: Case Report and Review of the Literature Wed, 06 Jan 2016 08:36:50 +0000 Strongyloidiasis is a helminthic disease which affects millions around the world resulting in a significant burden in certain high risk groups. It is rarely reported in the Lebanese population probably due to the low index of suspicion in common practice. We are reporting a case of strongyloidiasis that was found in an elderly patient presenting initially with dyspnea followed by skin rash, protein loosing enteropathy, diarrhea, and abdominal pain while on corticosteroid therapy. The diagnosis was suspected based on clinical presentation in addition to peripheral eosinophilia. We will also describe the upper and lower endoscopic aspects of the disease, as well as histologic findings on duodenal and colonic biopsies.

Left Colon Diverticulitis Presenting as Perforated Lumbar Abscess: A Case Report and Review of the Current Literature Thu, 31 Dec 2015 07:02:23 +0000 Diverticular perforation is a common complication of diverticulitis and can lead to the creation of abscesses. The presence of such abscesses on the abdominal wall is rare and can lead to misdiagnosis. We present the case of a patient with abdominal pain and the formation of a large left lumbar abscess due to perforation of a diverticulum of the left colon and our surgical treatment of choice with favorable results.

Sonographic and Endoscopic Findings in Cocaine-Induced Ischemic Colitis Mon, 21 Dec 2015 14:11:19 +0000 Cocaine-induced ischemic colitis is a recognized entity. The diagnosis is based on clinical and endoscopic findings. However, diagnostic imaging is helpful in the evaluation of abdominal symptoms and prior studies have suggested specific sonographic findings in ischemic colitis. We report sonographic and endoscopic images along with abdominal computed tomography in a case of cocaine-induced ischemic colitis. Thomas Leth, Rune Wilkens, and Ole K.

Mon, 14 Dec 2015 07:13:30 +0000 Hepatocellular carcinoma (HCC) usually occurs in patients with underlying risk factors such as liver cirrhosis and chronic hepatitis B. Although patients with Crohn’s disease (CD) are at an increased risk to develop malignancies such as colon cancer, the incidence of HCC in this population is extremely rare. We report a case of 62-year-old male with long history of CD treated with azathioprine (AZA) and aminosalicylic acid (ASA) who was incidentally diagnosed with HCC, for which left hepatectomy was done. Four years later during routine follow-up, patient had another hepatic lesion and underwent resection of the mass. The mechanism of occurrence of HCC in patient with CD is still controversial and may include immune mediated changes and medication related complications. AZA was reported in all case reports of CD that developed HCC. Through this report we hope to explore the complex pathophysiological mechanisms contributing to the development of HCC in the Crohn’s disease patient population.

Lanreotide Autogel in the Treatment of Persistent Diarrhea following a Total Colectomy Sun, 06 Dec 2015 12:01:06 +0000 Diarrhea is one of the most common complications following colectomy in patients with slow transit constipation (STC). Early postoperative diarrhea is usually treated with opioid agonists; however, to date, published data on the management of persistent diarrhea after colectomy for STC are scarce. Here, we report a case of severe diarrhea after a total colectomy with ileorectal anastomosis. One year after the surgery, the patient presented with persistent diarrhea. Treatment with a long-acting somatostatin analogue, lanreotide Autogel, was initiated. One month after the first injection of lanreotide Autogel the diarrhea was resolved. The patient’s stool transit was markedly improved (type 4 or type 5 according to the Bristol Stool Chart compared to type 7 before the treatment), positively affecting the patient’s quality of life (mean score of 2.1 on the Irritable Bowel Syndrome Quality of Life questionnaire compared to 3.9 before the treatment). This case report describes a successful use of lanreotide Autogel in a patient with persistent diarrhea after a total colectomy.

A Lethal Complication of Endoscopic Therapy: Duodenal Intramural Hematoma Mon, 30 Nov 2015 10:56:44 +0000 Duodenal intramural hematoma (DIH) usually occurs in childhood and young adults following blunt abdominal trauma. It may also develop in the presence of coagulation disorders and may rarely be an iatrogenic outcome of endoscopic procedures. Management of DIH is usually a conservative approach. A case of intramural duodenal hematoma that developed following endoscopic epinephrine sclerotherapy and/or argon plasma coagulation and that was nonresponsive to conservative therapy in a patient with chronic renal failure who died from sepsis is being discussed in this report. Clinicians should be aware of such possible complications after endoscopic hemostasis in patients with coagulation disorders.

Pegaspargase Induced Hypertriglyceridemia Resulting in Severe Fatal Pancreatitis Sun, 29 Nov 2015 12:53:45 +0000 Pegaspargase is used to treat acute lymphocytic leukemia (ALL). Pegaspargase definitely has its benefits in treating ALL; however we cannot lose sight of one of its very rare but potentially deadly complications, acute pancreatitis. Clinicians should monitor triglycerides while the patient is on treatment with Pegaspargase and suspect acute pancreatitis if the patient develops abdominal pain. If pancreatitis occurs, therapy should be stopped immediately and not reinstituted. For patients with hypertriglyceridemia without pancreatitis, discontinuation of therapy should be considered.

Portal Vein Thrombosis due to Prothrombin Gene Mutation following Sleeve Gastrectomy Tue, 10 Nov 2015 14:17:27 +0000 Introduction. Portomesenteric thrombosis is increasingly recognized as a complication of laparoscopic sleeve gastrectomy (LSG). It often presents with abdominal pain. We present a mother and her son who both developed portal vein thrombosis (PVT) after LSG. Case Description. A 43-year-old woman presented complaining of sudden severe abdominal pain, two weeks after she had uncomplicated laparoscopic sleeve gastrectomy. CT scan of the abdomen and pelvis with IV contrast showed portal vein thrombosis and SMV thrombosis. Two weeks later her son had the same LSG for morbid obesity and presented with the same clinical picture. Thrombophilia workup showed heterozygous prothrombin gene mutation. Conclusions. A high index of suspicion is necessary to diagnose PVT; although rare, it can be potentially lethal. Anticoagulation therapy should be initiated immediately to limit the morbidities and improve the outcome. Patients with family history of thrombophilia should be investigated prior to any bariatric surgery and nonsurgical alternative treatments for morbid obesity should be strongly encouraged.

Ischemic Colitis Caused by Intra-Aortic Balloon Pump Counterpulsation Sun, 01 Nov 2015 12:26:33 +0000 Intra-aortic balloon pump counterpulsation (IABP) has been shown to prolong life in critically ill cardiac patients. However, complications including distal emboli, balloon rupture, bleeding, limb loss, and bowel ischemia continue to be associated with them. We present a case of a 56-year-old male who suffered bowel ischemia as a result of a malpositioned IABP. While the benefit of such devices in critically ill patients is not disputed, patients as well as clinicians should be aware of the potential side effects and patients undergoing IABP placement should be monitored for complications.

Resolution of Fundic Gland Polyposis following Laparoscopic Magnetic Sphincter Augmentation and Subsequent Cessation of Proton Pump Inhibitors Tue, 27 Oct 2015 09:55:17 +0000 Gastric polyps occur from a variety of sources and are found commonly on upper endoscopy. We present the case of a 49-year-old female who presented for evaluation for antireflux surgery with a history of fundic gland polyposis who required twice-daily proton pump inhibitors (PPIs) for control of her gastric reflux. After verifying that she met criteria for surgery, she underwent an uncomplicated laparoscopic magnetic sphincter augmentation placement. With the cessation of PPIs following surgery, the fundic gland polyposis resolved. Fundic gland polyps may occur sporadically or within certain syndromes, such as familial adenomatous polyposis. Multiple possible inciting factors exist, including the use of PPIs. This is the first reported case of the resolution of numerous fundic gland polyps following the completion of laparoscopic magnetic sphincter augmentation. Joel R. Brockmeyer, Erin E.

Amyand’s Hernia: Rare Presentation of a Common Ailment Tue, 20 Oct 2015 12:11:09 +0000 Inguinal hernia with vermiform appendix as content is known as Amyand’s hernia. It is a rare entity but we encountered four cases within six months. A 52-year-old female had high grade fever and evidence of inflammatory pathology involving the ileocaecal region. She was initially managed conservatively and subsequently underwent exploratory laparatomy. The appendix was perforated and herniating in the inguinal canal. Appendectomy was done with herniorrhaphy without mesh placement. A 74-year-old male with bilateral inguinal hernia, of which, the right side was more symptomatic, underwent open exploration. Operative findings revealed a lipoma of the sac and a normal appearing appendix as content. Contents were reduced without appendectomy and mesh hernioplasty was performed. A 63-year-old male with an obstructed right sided hernia underwent emergency inguinal exploration which revealed edematous caecum and appendix as content without any inflammation. Contents were reduced without any resection. Herniorrhaphy was performed without mesh placement. A 66-year-old male with an uncomplicated right inguinal hernia underwent elective surgery. The sac revealed an appendix with adhesions at the neck. Contents were reduced after adhesiolysis and hernioplasty was performed with mesh placement. Emphasis is made to the rarity of disease, variation in presentation, and difference in treatment modalities depending upon the state of appendix.

Esophageal Cicatricial Pemphigoid as an Isolated Involvement Treated with Mycophenolate Mofetil Sun, 18 Oct 2015 13:05:30 +0000 Cicatricial pemphigoid (CP) is a rare blistering autoimmune disease. Esophageal involvement occurs in widespread disease and rarely appears as the only affected organ. We report a 67-year-old Caucasian female with esophageal dysphagia and weight loss. Several oral panendoscopies showed multiple exudative ulcerations with fibrin and webs in mid- and proximal esophagus and a peeling mucosa. There were no lesions in other organs. We established the diagnosis performing a direct immunofluorescence (DIF), demonstrating IgG3 and complement deposition along the basement membrane. As initial treatment the patient received prednisone 60 mg and 1 gr twice daily of mycophenolate mofetil (MMF) as a steroid-sparing agent due to its lower toxicity and its selective mechanism of action. Six months later there was a significant clinical improvement and the esophageal ulcerations had disappeared, developing cicatricial fibrous rings, although no stenosis was present. Four years later, the patient remains asymptomatic with a low maintenance dose of MMF.

Clinical Outcome of a Portosplenomesenteric Venous Thrombosis in Necrotizing Acute Pancreatitis with Protein C and S Deficiency Treated by Anticoagulation Therapy Alone Thu, 10 Sep 2015 12:43:55 +0000 Cases of splanchnic venous thrombosis have not been described in Cameroon. Their prevalence in acute pancreatitis is variable. With the emergence of acute intra-abdominal infections including typhoid fever and peritoneal tuberculosis in situations of acquired immunodeficiency syndrome, these cases will become frequent. We report the case of a portosplenomesenteric venous thrombosis related to necrotizing acute pancreatitis associated with proteins C and S deficiency, in a 46-year-old Cameroonian man, without particular past medical history. He was admitted for abdominal pain which had been evolving for 3 weeks and accompanied by vomiting. In the absence of hemorrhagic risk factor, the patient received low molecular weight heparin followed by oral warfarin. The abdominal ultrasound check on the 12th day showed a partial recanalization of venous thrombosis. The abdominal contrast-enhanced CT scanner at day 30 on oral anticoagulation therapy showed collateral vessels and small bowel edema. At the same time the upper gastrointestinal endoscopy showed grade II esophageal varices. We have maintained oral anticoagulation therapy. This case highlights that an early effective anticoagulation heparin therapy is needed for a clear benefit in case of suspected PSMVT. It is certain that the sooner the treatment is given, the better outcome will be.

The “Endothelialized Muscularis Mucosae”: A Case Report Describing a Large Cavernous Hemangioma at the Terminal Ileum and a New Histologic Clue for Preoperative Diagnosis from Endoscopic Biopsy Wed, 09 Sep 2015 08:18:08 +0000 Cavernous hemangiomas of the gastrointestinal tract are quite rare and, until now, have been difficult to diagnose preoperatively due their nonspecific presentations and imaging features, as well as a lack of histologic description pertaining to small superficial biopsies such as those obtained endoscopically. We report a unique case of a 4 cm transmural cavernous hemangioma in the terminal ileum with literature review and describe a new histologic finding—the “endothelialized muscularis mucosae,” which was discovered upon review of the endoscopic biopsy and could potentially facilitate preoperative diagnosis of these lesions from endoscopic biopsies in the future. These lesions have classically required surgical resection in order to make a definitive diagnosis and rule out malignancy, with which they share many historical and radiographic features. Due to their potential to cause bowel obstruction, intussusception, perforation, and hemorrhage, these lesions may ultimately require surgical resection to relieve symptoms or prevent or treat complications—however, surgical planning and patient counseling could be greatly improved by a preoperative diagnosis. Therefore, gastroenterologists, pathologists, and surgeons should be aware of the “endothelialized muscularis mucosae” which can be very helpful in diagnosing GI cavernous hemangiomas from endoscopic biopsies.

IgG4-Seronegative Autoimmune Pancreatitis and Sclerosing Cholangitis Tue, 25 Aug 2015 09:16:13 +0000 IgG4-related disease is a relatively novel clinical entity whose gastrointestinal manifestations include type 1 autoimmune pancreatitis (AIP) and IgG4-associated sclerosing cholangitis. The presence of elevated serum IgG4 is suggestive but not essential for the diagnosis of type 1 AIP and is a pervasive feature of the proposed diagnostic criteria. The differential diagnosis of type 1 AIP includes malignant conditions, emphasizing the importance of a deliberate, comprehensive evaluation. Management of patients with a suggestive clinical presentation, but without serum IgG4 elevation, is difficult. Here we present three cases of IgG4-seronegative AIP and sclerosing cholangitis that responded to empiric steroid therapy and discuss approach considerations. These cases demonstrate the value of meticulous application of existing diagnostic algorithms to achieve a clinical diagnosis and avoid surgical intervention. Allon Kahn, Anitha D. Yadav, and M.

Upper Gastrointestinal Bleeding from Gastric Amyloidosis in a Patient with Smoldering Multiple Myeloma Sun, 23 Aug 2015 06:00:16 +0000 Amyloidosis is a common complication of patients with monoclonal gammopathy of undetermined significance (MGUS), smoldering multiple myeloma (SMM), and multiple myeloma (MM). This proteinaceous material can be deposited intercellularly in any organ system, including the gastrointestinal (GI) tract. In the GI tract, amyloidosis affects the duodenum most commonly, followed by the stomach and colorectum. Gastric amyloidosis causes symptoms of nausea, vomiting, early satiety, abdominal pain, and GI bleeding. A case of upper GI bleeding from gastric amyloidosis is presented in a patient with SMM. Esophagogastroduodenoscopy (EGD) revealed a gastric mass. Endoscopic biopsies revealed amyloid deposition in the lamina propria, consistent with gastric amyloidosis. Liquid chromatography tandem mass spectrometry performed on peptides extracted from Congo red-positive microdissected areas of paraffin-embedded stomach specimens revealed a peptide profile consistent with AL- (lambda-) type amyloidosis. Based on this and multiple other case reports, we recommend that patients with GI bleeding and MGUS, SMM, or MM undergo EGD and pathologic examination of endoscopic biopsies of identified lesions using Congo red stains for amyloidosis for early diagnosis and treatment.

Ulcerating Ileocolitis in Severe Amatoxin Poisoning Tue, 18 Aug 2015 12:10:33 +0000 Amatoxin poisoning is still associated with a great potential for complications and a high mortality. While the occurrence of acute gastroenteritis within the first 24 hours after amatoxin ingestion is well described, only very few descriptions of late gastrointestinal complications of amatoxin poisoning exist worldwide. We present the case of a 57-year-old female patient with severe amatoxin poisoning causing fulminant but reversible hepatic failure that on day 8 after mushroom ingestion developed severe abdominal pain and watery diarrhea. Ulcerating ileocolitis was identified by computed tomography identifying a thickening of the bowel wall of the entire ileum and biopsies taken from the ileum and large bowel revealing distinct ileitis and proximally accentuated colitis. The absence of discernible alternative etiologies such as infectious agents makes a causal relationship between the ulcerating ileocolitis and the amatoxin poisoning likely. Diarrhea and varying abdominal pain persisted over several weeks and clinical follow-up after six months showed a completely symptom-free patient. The case presented highlights the importance to consider the possibility of rare complications of Amanita intoxication in order to be able to respond to them early and adequately.

Intestinal Amyloidosis in Common Variable Immunodeficiency and Rheumatoid Arthritis Sun, 16 Aug 2015 11:43:44 +0000 We present a case of reactive amyloidosis that developed secondary to common variable immunodeficiency and rheumatoid arthritis. A 66-year-old woman, with prior history of common variable immunodeficiency and rheumatoid arthritis, was referred to our clinic for chronic diarrhea investigation. The patient was submitted to colonoscopy with ileoscopy, which did not show relevant endoscopic alterations. However, undertaken biopsies revealed amyloid deposition. Since amyloidosis with GI involvement is a rare cause of chronic diarrhea, this pathology should be considered in etiologic investigation, especially when associated with chronic inflammatory diseases.

Superior Mesenteric Artery Syndrome Associated with Rapid Weight Loss Attributed to Amphetamine Abuse Thu, 13 Aug 2015 16:07:19 +0000 Superior mesenteric artery (SMA) syndrome arises from a reduction in the angle formed between the SMA and the aorta, thereby compressing the third portion of the duodenum. This phenomenon may be caused by a number of factors, one of which being acute weight loss. We report a case of a female patient presenting with abdominal pain and vomiting who developed superior mesenteric artery (SMA) syndrome as a result of rapid weight loss, thought to be secondary to amphetamine abuse. This association can often be overlooked and, to our knowledge, has not been previously reported. Richard M. Fazio, On Chen, and Wael Eldarawy Copyright © 2015 Richard M. Fazio et al.

Focal Intramucosal Adenocarcinoma Occurring in Gastric Hyperplastic Polyps: Two Case Reports Tue, 04 Aug 2015 12:51:24 +0000 Gastric hyperplastic polyps are generally considered benign lesions, although rare cases of adenocarcinoma have been reported. Two cases of intramucosal adenocarcinoma originating from gastric hyperplastic polyps that were successfully removed by endoscopic mucosal resection or endoscopic submucosal dissection are reported. On pathological examination, adenocarcinoma limited to the hyperplastic foveolar epithelial mucosa of the gastric hyperplastic polyps was observed.

A Rare Cause of Intestinal Obstruction in Infants: Ileum Duplication Cyst and Literature Review Thu, 30 Jul 2015 13:00:40 +0000 Cases of neonatal gastrointestinal system (GIS) obstruction are quite complex for pediatric surgery clinics. A rare cause of intestinal obstruction is the duplication cyst (DC). A three-day-old male patient presented at our clinic with a history of abdominal distension and bilious vomiting on the second day following birth. Although pathology had not yet been determined from observation and examination, surgery was performed when the patient could not tolerate oral feeding. An ileal DC forming an incomplete obstruction was observed. Ileoileal anastomosis was performed on the patient. Because DCs can present with different clinical symptoms, it is quite difficult to diagnose them in neonate patients. Lacking an imaging method that can provide an exact diagnosis, the diagnostic laparotomy is a suitable approach for both diagnosis and treatment to avoid delays in treatment.

Acute Portomesenteric Venous Thrombosis following Laparoscopic Small Bowel Resection and Ventral Hernia Repair Wed, 29 Jul 2015 13:16:16 +0000 Acute portomesenteric venous thrombosis is a rare but life-threatening complication of laparoscopic surgery that has been described in literature. Prompt diagnosis and early initiation of treatment are vital to prevent life-threatening complications such as mesenteric ischemia and infarction. A 51-year-old lady had laparoscopic small bowel resection and primary anastomosis with ventral hernia repair 4 weeks earlier for partial small bowel obstruction. Her postoperative period was uneventful and she was discharged home. Four weeks after surgery she developed watery diarrhea and generalized abdominal pain for four-day duration. A computed tomography of the abdomen revealed portomesenteric venous thrombosis although a computed tomography of abdomen before surgery 4 weeks back did not show any portomesenteric venous thrombosis. We are reporting a case of acute portomesenteric venous thrombosis as a complication of laparoscopic surgery.

Cannabinoid Hyperemesis Syndrome: A Paradoxical Cannabis Effect Wed, 22 Jul 2015 10:05:38 +0000 Despite well-established antiemetic properties of marijuana, there has been increasing evidence of a paradoxical effect in the gastrointestinal tract and central nervous system, given rise to a new and underrecognized clinical entity called the Cannabinoid Hyperemesis Syndrome. Reported cases in the medical literature have established a series of patients exhibiting a classical triad of symptoms: cyclic vomiting, chronic marijuana use, and compulsive bathing. We present a case of a 29-year-old man whose clinical presentation strongly correlates with cannabinoid hyperemesis syndrome. Despite a diagnosis of exclusion, this syndrome should be considered plausible in the setting of a patient with recurrent intractable vomiting and a strong history of cannabis use as presented in this case.

A Rare Cause of Acute Abdomen: Perforation of Double Meckel’s Diverticulum Wed, 22 Jul 2015 08:19:02 +0000 Meckel’s diverticulum is the most common congenital anomaly of the gastrointestinal tract. In this report, we aimed to represent a case of intestinal perforation, caused by double Meckel’s diverticulum, which is a very rare entity in surgical practice. The patient was a 20-year-old Caucasian man, admitted to hospital with complaints of abdominal pain, nausea, and vomitting during the last 3 days. Physical examination indicated tenderness, rebound, and guarding in the right lower quadrant of abdomen. Abdominal X-ray revealed a few air-liquid levels in the left upper quadrant. In the operation, 2 Meckel’s diverticula were observed, one at the antimesenteric side, at 70 cm distance to the ileocecal valve, approximately in 3 cm size, and the other between the mesenteric and antimesenteric sides, approximately in 5 cm size. The first one had been perforated at the tip and wrapped with omentum. A 30 cm ileal resection, including both diverticula with end-to-end anastomosis, was performed. The diagnosis of symptomatic Meckel’s diverticulum is considerably hard, especially when it is complicated. Diverticulectomy or segmentary resections are therapeutic options. In patients with acute abdomen clinic, Meckel’s diverticulum and its complications should be kept in mind, and the intestines should be observed for an extra diverticulum for caution although it is a very rare condition.

A Novel Endoscopic Method to Relieve Food Impaction Using an Inflatable Balloon Tue, 21 Jul 2015 14:15:38 +0000 Food impaction in the esophagus is a relatively common medical emergency. Most of these food impactions are relieved spontaneously. But for complete esophageal food impactions or impactions not relieved spontaneously, traditional endoscopic methods like using a Roth net, polypectomy snare, or rat or alligator tooth forceps are used to gently manipulate the food material into the stomach. However, these methods may not work in certain circumstances. We present a case of proximal esophageal food impaction that was relieved using an inflatable balloon after the conventional methods proved unsuccessful.

Coccidioidomycosis Masquerading as Eosinophilic Ascites Tue, 21 Jul 2015 13:04:35 +0000 Endemic to the southwestern parts of the United States, coccidioidomycosis, also known as “Valley Fever,” is a common fungal infection that primarily affects the lungs in both acute and chronic forms. Disseminated coccidioidomycosis is the most severe but very uncommon and usually occurs in immunocompromised individuals. It can affect the central nervous system, bones, joints, skin, and, very rarely, the abdomen. This is the first case report of a patient with coccidioidal dissemination to the peritoneum presenting as eosinophilic ascites (EA). A 27-year-old male presented with acute abdominal pain and distention from ascites. He had eosinophilia of 11.1% with negative testing for stool studies, HIV, and tuberculosis infection. Ascitic fluid exam was remarkable for low serum-ascites albumin gradient (SAAG), PMN count >250/mm3, and eosinophils of 62%. Abdominal imaging showed thickened small bowel and endoscopic testing negative for gastric and small bowel biopsies. He was treated empirically for spontaneous bacterial peritonitis, but no definitive diagnosis could be made until coccidioidal serology returned positive. We noted complete resolution of symptoms with oral fluconazole during outpatient follow-up. Disseminated coccidioidomycosis can present in an atypical fashion and may manifest as peritonitis with low SAAG EA. The finding of EA in an endemic area should raise the suspicion of coccidioidal dissemination. Kourosh Alavi, Pradeep R. Atla, Tahmina Haq, and Muhammad Y.

Characteristics of Small Bowel Polyps Detected in Cowden Syndrome by Capsule Endoscopy Wed, 24 Jun 2015 11:23:03 +0000 Cowden syndrome is an uncommon, autosomal dominant disease characterized by multiple hamartomas and hyperplastic lesions in the skin, mucous membrane, brain, breast, thyroid, and gastrointestinal tract. About 30% of Cowden syndrome cases are reportedly complicated by malignant diseases. Hamartomatous polyps occur throughout the gastrointestinal tract, the most common sites being the stomach, colon, esophagus, and duodenum. Small bowel polyps can occur in Cowden syndrome; however, they are difficult to detect by conventional examination, including double-contrast X-ray study. Here, we report three cases of Cowden syndrome with small bowel polyps, which were detected by capsule endoscopy. The small bowel polyps of Cowden syndrome frequently occur at the oral end of the small bowel, especially in the duodenum and jejunum, and their color is similar to that of the surrounding mucosa; additionally, the polyps are relatively small (2–5 mm). Capsule endoscopy is useful for detecting small bowel polyps in Cowden syndrome.
