Sigmoid Duplication a Rare Cause of Colon Obstruction Due to Fecal Material Bezoar; A Case Report

Abstract

Intestinal duplication is a rare congenital disorder that can occur anywhere in the gastrointestinal tract. The
pathophysiology of duplications remains unclear, and various theories have been proposed. This report presents a case of a young man who came to the clinic with constipation and obstructive defecatory syndrome. Preoperative colonoscopy and imaging revealed no abnormalities in the colon. During the operation, a large colon mass was found and resected, and a primary colocolic anastomosis was performed laparoscopically. After specimen extraction, the colon was cut to assess the etiology. A congenital duplicated lumen of the sigmoid was found, with an accumulation of fecal material in the second lumen causing pressure and obstructing the main lumen. Duplications are a rare cause of intestinal obstruction and should be considered in the differential diagnosis of chronic or partial obstruction. This appears to be the first reported case of laparoscopic resection of sigmoid duplication in an adult man with chronic constipation in the literature.
