Tubular Duplication of the Sigmoid Colon with Acute Abdomen: An Adult Case Report

Colonic duplication is a rare abnormality, comprising only 6�7 of all gastrointestinal duplications and usually present during the first decade of life. Tubular duplications of the sigmoid colon are extremely rare and only a few cases have been reported in the literature. In this study, we report the case of a 27-year-old rural man visited our hospital with symptom of repeated episodes of abdominal pain in epigastric region that radiated to right flank and back. An abdominal computed tomography (CT) scan with oral and intravenous contrast revealed an extremely dilated and air-filled loop related to sigmoid colon. An exploratory laparotomy was performed and tubular sigmoid colon duplication was found intraoperatively. The postoperative period was uneventful. © 2014, Association of Surgeons of India
