Rectal prolapse can be diagnosed easily by having the patient strain as if to defecate. A laparoscopic rectopexy should be recommended. Intussusception is more an epiphenomenon than a cause of defecatory disorder and should be managed conservatively. Solitary rectal ulcer syndrome is a consequence of chronic straining, and therapy should include restoring a normal defecation habit. Rectocele should be left alone; an operation may be considered if it is larger than 3 cm and is causing profound symptoms despite maximizing medical therapy for the associated defecation disorder.,
