Case report: Sigmoid strangulation from evisceration through a perforated rectal prolapse ulcer – An unusual complication of rectal prolapse

INTRODUCTION: Rectal prolapse occurs particularly in elder females and presentation can sometimes lead to complications such as strangulation and evisceration of other organs through the necrotic mucosa. PRESENTATION OF CASE: This is a case of a 61 year-old female with rectal prolapse complicated by rectal perforation through which a segment of sigmoid colon eviscerated and became strangulated. This patient initially presented with sepsis requiring ICU admission, but fully recovered following a Hartmann's procedure with a sacral rectopexy. DISCUSSION: Complications of rectal prolapse include incarceration, strangulation, and rarely, perforation with evisceration of other viscera requiring urgent operation. This report provides a brief overview of complications associated with rectal prolapse, reviews similar cases of transrectal evisceration, and discusses the management of chronic rectal prolapse. CONCLUSION: Prompt surgical consult is warranted if any signs or symptoms suggestive of complications from prolapse are present.
