PURPOSE A complication after restorative rectal surgery with a straight anastomosis is low-anterior resection syndrome with a postoperatively deteriorated anorectal function. The colonic J-reservoir is sometimes used with the purpose of reducing these symptoms. An alternative method is to use a simple side-to-end anastomosis or a coloplasty. MATERIAL AND METHODS Three-hundred fiftyseven patie...

background and objectives: gastrointestinal polyps are proliferative or neoplastic mucosal lesions. the most important point about these polyps is risk of malignancy of them. this study was performed to determine type and frequency of polyps of gastrointestinal tract in iranian population according to their locations. materials and methods: totally, 210 patients referred to rasul-e-akram hospi...

OBJECTIVES The introduction of the colonic J-pouch has markedly improved the functional outcome of restorative rectal cancer surgery. However colonic J-pouch surgery can be problematic and may present some late evacuatory problems. To overcome these limitations a novel pouch has been proposed: the transverse coloplasty pouch. The purpose of our study was to compare the functional outcomes of th...

We recently reported that immobilization stress increased colonic motility, mucin, and prostaglandin E2(PGE2) release and mucosal mast cell degranulation in rat colon [ Proc. Natl. Acad. Sci. USA 93: 12611-12615, 1996; Am. J. Physiol. 271 ( Gastrointest. Liver Physiol. 34): G884-G892, 1996]. To directly assess the contribution of mast cells, we compared colonic responses to stress in mast cell-...

Ruehm University Hospital Essen, 45122 Essen, NRW, Germany, Department of Radiology, Crete, Crete, Greece ABSTRACT: The aim of this study was to assess MR colonography for the detection of colonic polyps/malignancy. 50 subjects underwent MR colonography prior to conventional colonoscopy. MRC is based on a rectal enema with water in c...

Intussusception in adults is very rarely seen, and this cause acute abdomen. A computed tomography (CT) scan, clinical suspicion, history, and a physical examination are important for the diagnosis. We present two cases of colonic intussusceptions induced by lipoma. The cases had similar locations, diagnoses, and management. Both lipomas were located close to the cecum in the ascending colon, a...
