Abscess formation of a spherical-shape duplication in the splenic flexure of the colon: case report and review of the literature.

Gastrointestinal tract duplications are rare congenital malformations that may occur anywhere in the alimentary tract from the mouth to the anus, and vary greatly in presentation, size, location, and especially in symptoms. We present a case of an infected spherical colonic duplication, in a 20-day-old baby, located at the splenic flexure of the colon. The prominent symptom was acute abdomen, accompanied by bilious vomiting, intestinal obstruction, and high fever. We present this case, due to atypical clinical presentation and the inability of the imaging modality to establish the diagnosis preoperatively.

Massive intestinal ischemia, a rare complication of oral contraceptive-induced mesenteric venous thrombosis: a case report and review of literature.

Intestinal necrosis and perforation is a clinical and pathological presentation of the infrequently seen mesenteric venous thrombosis in women using oral contraceptives.We report a case of a previously healthy 31-year-old female patient, who presented with a 3-day history of abdominal pain.Although chest and abdomen radiographs showed small bowel obstruction, conservative treatment failed and the patient developed peritonism. Contrast-enhanced Tomography of the abdomen revealed free air associated with dilated and thickened small bowel. A laparotomy was performed and segmental resection of both small and large bowel was required. The pathological examination showed intestinal ischemia and mesenteric venous thrombosis. There were no further predisposing factors and mesenteric venous thrombosis was ascribed to oral contraceptives.
