Rectal prolapse causes

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Shaghayegh Habibi, M.D.[2]

Overview

More common causes of rectal prolapse include rectal denervation, perineal nerve injury, kinking of the redundant loop of sigmoid colon, altered colonic motility and less common causes include relaxation of lateral ligament and pelvic floor muscles and loss of rectal compliance.

Causes

More common causes

More common causes of rectal prolapse include:^[1]^[2]

Rectal denervation
Perineal nerve injury (due to descent of the pelvic floor, viginal delivery and excessive straining during defection)
Kinking of the redundant loop of sigmoid colon at the junction between the sigmoid colon and the rectum
Altered colonic motility
Anismus (paradoxical contractions of the pelvic floor)^[3]^[4]

Less common causes

Less common causes of rectal prolapse include:^[1]^[2]

Relaxation of the lateral ligaments
Relaxation of the pelvic floor muscles
Loss of rectal compliance as a result of mesh placement
