The rectal pouch may hang loosely in the pelvic orabdominal cavity, or be attached to some contiguous structure. A distinctfibrous band may lead from the skin to the rectal pouch, or only cellulartissue may intervene. The operation for relief consists in first placing the patient, properlyanaesthetized, in the dorsal position with the pelvis elevated. Then intro-duce a sound into the bladder if the patient be a male, or into the vaginaif a female, and make a vertical incision in the me
