Pouch perineal rectosigmoidectomy: a case report.

Many surgical methods have been described for the treatment of full-thickness rectal prolapse. Rarely, unusually large lengths of colon must be excised, thus resulting in a significant loss of the absorptive function of the remaining colon. We present an unusual case in which an extraordinary length of the colon was excised and a perineal reservoir was created in the form of a colonic J-pouch to improve continence.
