Complete rectal prolapse occurs when the full thickness of the rectal wall protrudes through the anus. It is rare and commonly develops in elderly people. The chief complaints associated with this condition are constipation and/or fecal incontinence; the patient's quality of life is diminished.

A 43-year-old female presented to the hospital with protrution of the entire circumference of her rectum from the anus. She had a history of laxative abuse and severe straining associated with anorexia nervosa, resulting in complete rectal prolapse. After having a detailed evaluation, she underwent a laparoscopic rectopexy. Although her laxative abuse and straining continued postoperatively, she has had no recurrence of the rectal prolapse for over a year after surgery. Laparoscopic surgery is a minimally invasive treatment, and the recurrence rate is low compared with the perineal approach. Further case analyses are needed, but the laparoscopic approach may become the standard treatment for rectal prolapse.
