RESUMEN
The author reports the results of his experience in reconstructive surgery of the abdominal wall and of statics disorders of the pelvic organs on colo-rectal functional disturbances. Hernias and mostly eventration of the anterior or lumbar abdominal wall diminish or suppress the abdominal pressure aiding in the emptying of the rectum. Large dacron sub-peritoneal prostheses provide strength and permit an effective muscular contraction. Pelvic statics disorders cause painful manifestations, difficult to analyze, and the patients are torn between gynecologist and proctologist: these are painful symptoms of the Douglas' cul-de-sac. Examination must be based on objective signs obtained from barium enema during defecation. The treatment rests on a high fixation of pelvic organs and obliteration of the cul-de-sac.
