Management of acute incarcerated rectal prolapse.

Perineal excision was used to treat eight elderly patients with acute incarcerated prolapse: four showed signs of strangulation with areas of gangrene, six made an uneventful recovery without colostomy, and two developed anastomotic leak, needing diverting colostomy with a complete recovery. There were no mortalities. There were no recurrences of rectal prolapse.
