Duodenal variceal bleeding is an uncommon complication of portal hypertension that can easily go unrecognized and reach mortality rates as high as 40%. Cirrhosis is the most common cause of duodenal varices. In most cases, duodenal varices occur concomitantly with esophageal varices, further complicating identification with initial endoscopy. Although many modalities have been explored with res...

Hypotonic duodenography is a well recognized and well established procedure (Mallet-Guy and Jacquemet, 1963), by which the duodenal loop is outlined in a flaccid state. Variations of contour due to inherent duodenal movement are thus overcome. A constant pattern of the inner wall of the duodenal mucosa is obtained unobscured by overlying stomach, and even minor distortions become visible. Lesio...

Background: Duodenal cancer is one of the leading causes of death in familial adenomatous polyposis (FAP) patients. An endoscopic surveillance programme was therefore initiated in 1988, the outcome of which is described in this paper. Methods: We report the 10 year follow up of 114 patients with FAP who were prospectively screened for the presence and severity of duodenal adenomas. Results: Six...

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...

Most discussions about the aetiology of duodenal ulcer depict the duodenal bulb as a battlefield, on which aggressive and defensive factors wage a continuous and continuing campaign for the integrity of the bulbar mucosa. When the scales are tipped in favour of aggression, an ulcer develops. The battlefield is unique, because it is chemical warfare that is usually thought to be taking place hen...

BACKGROUND Helicobacter pylori infection of the gastric mucosa is vital in the pathogenesis of duodenal ulcer disease. H pylori will only colonise gastric epithelium and its association with duodenal disease is therefore not easily explained. AIMS To determine if gastric metaplasia in the duodenum increases the risk of duodenal ulcer disease in children infected with H pylori. PATIENTS All ...

Duodenal lipomas are relatively uncommon and are rarely responsible for clinical symptoms. Occasionally, searching for aetiology of gastrointestinal bleeding leads to the final diagnosis of duodenal lipomas. Here, we present the case of a 68-year-old woman who suffered with repeated melena and weight loss. Endoscopy, abdominal computed tomography (CT) and histopathological outcomes are describe...

Aim: To assess the usefulness of duodenoscopy in the diagnosis of duodenal ulcers in dogs. Materials and Methods: Sick dogs with chronic gastrointestinal problems were physically examined and samples were collected for haematology, biochemistry and faecal examination. Duodenal biopsies, duodenal contents and brush cytology were obtained via duodenoscopy. Results: Seven duodenal ulcers cases wer...

Thirty nine children with recurrent abdominal pain aged between 5.5 and 12 years, underwent endoscopic duodenal biopsy to find out if there were any duodenal inflammatory changes, and if there was a relationship between duodenal inflammation and intestinal permeability to 51Cr-EDTA. Duodenal inflammation was graded by the duodenitis scale of Whitehead et al (grade 0, 1, 2, and 3). In 13 out of ...
