Chronic Non-toxic Megacolon Secondary to Diverticulitis: a case report

Purpose: There are very few known cases of secondary non-toxic megacolon caused by complicated diverticulitis in literature and none of these have ever presented ab-extrinsic compression. Methods: : We present the case of a 65-year-old female patient with an unknown history of diverticulosis who presented to our hospital with a distended abdomen secondary to the obstruction of the sigmoid-rectum junction identified by an abdominal CT scan. Results: : Complicated diverticulitis created a fibrous string from the sigmoid-rectum junction to the homolateral ovary which caused an extrinsic compression leading to intestinal obstruction and non-toxic megacolon. Conclusion: The purpose of this report is to share our experience and therapeutic choices to enrich the literature and prmote a better understanding of the disease.
