Annular pancreas (AP) is a rare congenital abnormality in which the ventral portion of fails to rotate with duodenum during embryological development, thus causing remain partially or fully enveloped around duodenum. The actual incidence AP unknown, as many cases are asymptomatic and undiagnosed. Adults may present variety symptoms suggestive gastric outlet obstruction, gastrointestinal bleedin...

Estimations of the viscosity of the whole blood and plasma of the dog after experimental upper gastrointestinal tract obstruction are reported. With cardiac obstruction there is a rapid and marked rise in the viscosity of the whole blood and some increase in the viscosity of the plasma. The changes after pyloric obstruction are similar to those observed after cardiac obstruction. After obstruct...

Bezoars are concretions of swallowed hair, fruit vegetable fibers, and similar substances found in the alimentary canal. The first description of a postmortem human bezoar was by Swain in 1854. Although the prevalence of bezoars in humans is low, an absence of treatment has been associated with mortality rates as high as 30%, primarily because of gastrointestinal bleeding, destruction, or perfo...

Gallstone ileus is a complication of cholelithiasis resulting from a fistula between the gallbladder and the gastrointestinal tract. If sufficiently large, a gallstone may lodge at the narrowest part of the gastrointestinal tract, usually the terminal ileum, and present with small bowel obstruction. Here the authors present the unusual case of an 82-year-old man who developed symptoms and signs...

Duodenal lipomas are rare benign tumors and pose a diagnostic challenge as their symptoms are non-specific. In this article, we reported a case of duodenal lipoma presenting as upper gastrointestinal obstruction and reviewed the literature on relevant clinical manifestation, diagnosis and treatment. Our review of literature indicated that multiple duodenal lipomas as a cause of upper gastrointe...

Peutz-Jeghers syndrome is a rare hereditary autosomal dominant disease caused by a mutation of the tumor suppressor gene serine/threonine kinase 11 located in chromosome 19p13.3. It is characterized by the presence of extensive mucocutaneous pigmentation, especially of the lips and the occurrence of hamartomatous polyps throughout the gastrointestinal tract. Gastrointestinal hamartomas occur pr...

An unusual case of upper gastrointestinal hemorrhage due to an isolated varix involving the 2nd part of the duodenum is presented here. The varix was the result of Chronic Pancreatitis induced the superior mesenteric vein obstruction. The diagnosis was made preoperatively by upper gastrointestinal endoscopy and selective mesenteric angiogram. Patient was treated successfully with Mesocaval shun...

Bezoars can result from any indigestible or poorly digestible substance that is capable of forming concretions within the gastrointestinal tract including stomach and small intestine. Phytobezoars are composed of concretions of vegetable matters [1]. Most of patients with bezoars are asymptomatic but intestinal obstruction has been reported [2]. Small intestinal phytobezoars are almost always o...

Meckel's diverticulum (MD) is considered the most common congenital gastrointestinal malformation affecting 2% of population. Complications including hemorrhage, diverticulitis, and intestinal obstruction occur in only 4% patients with MD. This article presents imaging findings a small bowel intussusception caused by Meckel’s diverticulitis 10-year-old girl.

After high gastrointestinal tract obstruction the blood fibrin increases rapidly. The change is more marked in animals with obstruction of the cardiac end of the stomach. The rise in fibrin parallels closely the toxemia characteristic of such conditions. These results indicate that liver insufficiency cannot be the cause of death in such obstructions.
