Even more rarely, it becomes gangrenous, necessitating emergency surgery. We describe an extremely rare case of gangrenous rectal prolapse. The patient underwent emergency perineal proctosigmoidectomy, the Altemeier operation. The postoperative course was quite uneventful with an excellent final result. The successful treatment of this patient illustrates the value of the Altemeier procedure in the difficult and unusual case scenario of bowel incarceration complicated with gangrene.
