A study of the internal morphology of the alimentary canal of Chrysoperla rufilabris (Brumeister) adults in relation to yeast symbionts was conducted using light, scanning, and transmission electron and epißuorescence microscopy. The alimentary canal of Þeld-collected adults possessed a single large ( 300Ð400 m in length) diverticulum at the posterior end of the foregut. Although yeast cells (4...

INTRODUCTION Perforations of jejunal diverticula are uncommon and repeated symptomatic perforations have been reported only twice before in the literature. This is the first case report of recurrent perforation of a jejunal diverticulum to be successfully managed non-operatively. CASE PRESENTATION We report a recurrent perforation of a jejunal diverticulum in an 87-year-old Caucasian man who ...

INTRODUCTION Duodenal diverticula are uncommon and usually asymptomatic. Complications like bleeding, perforation and biliary fistulae are rare. The management of a bleeding duodenal diverticulum can be challenging. With the improvement of endoscopic techniques, many of the cases reported in the literature were managed with endoscopic methods. We present a case report of bleeding duodenal diver...

A solitary small intestinal ulcer associated with a carcinoid tumour in a nearby Meckel's diverticulum was found in a 77 year old man presenting with massive rectal bleeding. Angiography and a radioisotope study localised the bleeding to the ileum. At operation, the Meckel's diverticulum was identified, with bleeding from an ulcer just distal to it. Pathological examination revealed a small car...

Giant sigmoid diverticulum (GSD) is a rare complication of diverticulosis. These lesions arise from herniations of the mucosa through the muscle wall which progressively enlarge with colonic gas to become large air-filled cysts evident on plain X-ray and CT scans. We present a rare case of a 72-year-old female presenting with abdominal distention, abdominal tenderness, and fever who developed a...

UNLABELLED Meckel's diverticulum is the most common congenital malformation of the gastrointestinal tract. It can cause complications in the form of ulceration, hemorrhage, intussusception, intestinal obstruction, perforation and, very rarely, vesicodiverticular fistulae as noted in six previously reported cases. 66-year-old woman was presented with an enterovesical fistula. Exploratory laparot...

Meckel's diverticulum is the commonest congenital malformation of gastrointestinal tract and represents a persistent remnant of the omphalomesenteric duct. Although it mostly remains silent, it can present as bleeding, perforation, intestinal obstruction, intussusception, and tumours. These complications, especially bleeding, tend to be more common in the paediatric group and intestinal obstruc...

Objective. The aim of this study was to evaluate the results of open surgical techniques in the treatment of Zenker diverticulum. Study Design. Case series with chart review. Setting. Academic tertiary referral center. Subjects and Methods. Fifty-four patients with Zenker diverticulum were treated using a transcervical approach. Three with a Brombart I diverticulum underwent a simple myotomy of...

A case of a giant right atrial diverticulum associated with neonatal supraventricular tachycardia is reported. The electrocardiogram in sinus rhythm showed pre-excitation that may have been caused by the right atrial diverticulum adhering to the right ventricle.

INTRODUCTION Although duodenal diverticula are common, periampullary duodenal diverticula are rare. Periampullary duodenal diverticula are usually asymptomatic and may be difficult to diagnose and treat. However, they may present with massive bleeding, requiring prompt diagnosis. CASE PRESENTATION We report the case of a 71-year-old Asian woman with bleeding from a periampullary duodenal dive...
