Abstract
Two cases of diffuse cavernous hemangioma of the rectum and rectosigmoid colon are reported. Sphincter-saving procedures were applied as the surgical treatment for these two patients. The diseased rectum and distal sigmoid colon were resected 3 cm above the pectinate line. The mucosa of the rectal stump was extirpated. All visible residue from the hemangiomatous tissues on the muscular cuff, pararectal space, and pelvic wall were denuded. The normal colon was then pulled down through the rectal cuff and anastomosed with anoderm, and attached to the internal sphincter muscle. Both patients recovered uneventfully. No uncontrollable hemorrhage was encountered during rectal dissection. Both patients had good anal sensation and perfect continence. No complicated sexual or urinary disturbances were found. The sphincter-saving procedure for treatment of diffuse cavernous hemangioma of the rectum should be promoted and given first choice whenever possible.
