purpose: to compare the prevalence of glaucoma among peptic ulcer patients with or without helicobacter pylori infection. methods: among 352 patients with an indication of gasterointestinal endoscopy for peptic problems, 120 patients in 18-88 years of age were included for evaluation of glaucoma. according to the results of histopathologic and urease test, they were divided into two groups: hel...

BACKGROUND Allergy and functional gastrointestinal disorders have been associated with eosinophilia in duodenal mucosa. AIM To assess the prevalence of eosinophilia in duodenal biopsies of patients attending for oesophogastroduodenoscopy and delineate associated clinical conditions. METHODS A total of 155 patients (mean age 55 years, 59% women) with normal duodenal biopsies were randomly se...

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 Si...

The aim of this study was to examine the influence of cholecystokinin (CCK)-octapeptide (OP) and its amphibian analogue cerulein infusions on duodenal myoelectric and motor activities, as well as to compare the effects of CCK peptides on duodenal bulb and duodenal motility in non-fasted conscious rams. Five rams underwent implantation of bipolar platinum electrodes to the duodenal bulb, and dis...

BACKGROUND Coeliac disease is characterised by villous atrophy, which usually normalises after gluten withdrawal. Sometimes the revaluation of duodenal histology is required during follow-up, even if the methodology for comparing duodenal histology before and after introducing a gluten-free diet is not yet established. Our aim was to evaluate a novel criterion to compare duodenal histology in c...

Some 80-90% of gastrinomas are located in the gastrinoma triangle, which includes the duodenum, the pancreatic head, and the hepatoduodenal ligament. The natural history of the tumors depends on their origin. Duodenal gastrinomas are much less aggressive than pancreatic primaries and infrequently develop liver metastases. The reason therefore is unclear. The transcription factor pancreatic-duod...

One of the causes of congenital incomplete duodenal obstruction is the presence of duodenal membranes. This condition requires a high index of suspicion for an early and accurate diagnosis. We present two cases of duodenal obstruction with initial diagnosis of foreign bodies that were surgically intervened and where incomplete duodenal membranes were an incidental finding. The clinical course o...

At operations on 150 patients the duodenal bulb was examined for local features which predispose it to peptic ulceration. A surgeon now has the opportunity to study the duodenum in its natural state and normal situation in both healthy and ulcerated conditions. When gastroenterostomy or partial gastrectomy were routinely used for the cure of duodenal ulcers, the bulb was either left unopened or...

Background: Cytotoxin-associated gene A (CagA)-positive strains of Helicobacter pylori are associated with gastroduodenal diseases. Evidences have suggested that the type of H pylori CagA EPIYA motifs may be associated with specific disorders (i.e., gastritis, peptic ulcer, or gastric cancer).  We investigated the prevalence of different EPIYA motifs (A, B, C, or D) in H. pylori strains is...
