Acute pseudo–obstruction of the colon or ogilvie syndrome results in massive colonic dilatation that may lead to a life threatening perforation. Pseudo–obstruction are terms used to denote a condition in which patients appear to have signs and symptoms suggestive of intestinal obstruction without an evident mechanical source. This problem is often seen in association with other diseases and occasionlly complicates the post-operative course of patients who have under gone one of several typesof operations, particulary abdominal surgery. Predisposing factors include different medical and surgical illness. Renal failure and Kidneay transplantation are perdisposing factors: The presented case was a complication of renal failure, who was diagnosed and operated because of peritonitis secondary to cecal perforation. Colonic decompression by means of colonoscopy is the most effective therapeutic modality for pseudo – obstruction of colonic dilation. If the bowel is ischemic or perforated, surgical intervention will be indicated.
