ABSTRACT: A 7 1/2 year old boy presented with intractable constipation and recurrent fecal impactions refractory to medical therapy. History and findings suggested that the child had a low anorectal malformation(ARM) with an anal membrane which ruptured spontaneously soon after birth. The boy had undergone surgery at 2 days of age for peritonitis when a grossly ectatic rectum and sigmoid colon were found along with a small perforation in the sigmoid colon. During the present admission, the anus was found to be of normal caliber with good sphincteric tone. Barium enema revealed a massive localized dilatation of the rectosigmoid colon. Complete cure of symptoms was achieved by subtotal resection of the dilated segment and anastomosis of normal descending colon with the lower rectum. Megasigmoid probably results from a primary congenital anomaly of the terminal bowel and has several features in common with segmental dilatation of the colon(SDC) and congenital pouch colon (CPC)d.
