BACKGROUND The presence of gastric metaplasia allows helicobacter pylori to colonise the duodenum and this condition is thought to be acquired as a response to acid hypersecretion. This functional disorder, however, is present only in a subgroup of duodenal ulcer patients and, in addition, surface gastric metaplasia has been frequently found in the proximal duodenum of normal subjects and patie...

BACKGROUND Epidemiology of peptic ulcer disease (PUD) in India differs from that in the West. It may have undergone a change with recent improvement in hygiene and availability of potent antisecretory and ulcerogenic drugs. We therefore tried to assess time-trends in the frequency of PUD over the past two decades. METHODS Records of patients with uninvestigated dyspepsia and no alarm symptoms...

SAITO, A. Relation of the Acidity of Gastric Juice to Cancer and Ulcer of the Gastroduodenal Tract. Tohoku J. exp. Med., 1973, 111 (4), 323-345-The author has statistically studied the acidity of gastric juice obtained from 1,100 cases of gastric cancer, 29 cases of gastric polyps, one case of gastric sarcoma, one case of gastric myoma, 5 cases of duodenal cancer, 570 cases of gastric ulcer, 90...

Both KB-5492, a new anti-ulcer agent, and cimetidine, administered orally at 25-200 mg/kg, dose-dependently prevented cysteamine (400 mg/kg, s.c.)-induced duodenal ulcers in rats with ED50 values of 63 and 40 mg/kg, respectively. Anti-ulcer doses of cimetidine, but not KB-5492, inhibited gastric acid hypersecretion induced by cysteamine (400 mg/kg, s.c.). In contrast, anti-ulcer doses of KB-549...

Serum gastrin concentrations were measured in patients with duodenal ulcer and controls before, during, and after one-hour intravenous infusion of various doses of adrenaline (0.12 microgram to 6 microgram/min). Gastrin concentrations in the basal state were significantly increased in duodenal ulcer patients compared to controls. The maximal rise in serum gastrin concentrations was obtained at ...

Changes in histamine storage in the oxyntic mucosa of duodenal ulcer patients and their reversal by vagotomy and the histamine H2-antagonist cimetidine supported the hypothesis that histamine could be a causal factor in peptic ulcer pathogenesis. The specificity of these findings was impaired by problems in biopsy taking, however, and in the preparative steps before measuring the actual histami...

In order to ascertain possible abnormalities in somatostatin and gastrin secretion in patients with duodenal ulcer, the author compared bombesin-stimulated somatostatin and gastrin secretion by antral mucosal explants in patients with duodenal ulcer, those with atrophic gastritis and normal controls. An organ culture technique was employed. This excluded neurogenic, hormonal and circulatory inf...

A 56-year-old woman presented with a 1-month history of right upper quadrant abdominal pain after a laparoscopic cholecystectomy for gallstones. Her medical history included endoscopic retrograde cholangiopancreatography (ERCP) performed 4months prior to the laparoscopic cholecystectomy for the treatmentof common bile duct (CBD) stones. During this procedure duodenal ulcers had also been found ...

INTRODUCTION Helicobacter pylori (H. pylori) occurs throughout the world and causes gastroduodenal diseases. There is data indicating a change in the prevalence of H. pylori infection worldwide. The prevalence of H. pylori is 80% in Turkey, while it is higher in many developing countries, and the rate of infection varies throughout the world. In many developing countries, the prevalence of infe...

OBJECTIVE To evaluate partial and complete circular duodenectomy combined with highly selective vagotomy (HSV) for relief of gastric retention. DESIGN A retrospective, case-comparison study. SETTING University hospital referral center. PATIENTS Eighteen patients with severe obstructing duodenal ulcer disease defined by failure of a saline load test and endoscopic narrowing of the gastric ...
