@entity1 @entity2477 @entity458 @entity548
Two cases of diffuse @entity2477 of the rectum and rectosigmoid colon are reported. Sphincter-saving procedures were applied as the surgical treatment for these two @entity1 . 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 @entity1 recovered uneventfully. No uncontrollable @entity548 was encountered during rectal dissection. Both @entity1 had good anal sensation and perfect continence. No complicated @entity458 were found. The sphincter-saving procedure for treatment of diffuse @entity2477 of the rectum should be promoted and given first choice whenever possible.
