Abstract

Gastro – intestinal duplications are usually detected in children before 2 years of age due symptoms/complications associated with the condition or during surgery in the child for some unrelated condition. In adults colonic duplication is of rare occurrence and often diagnosed during surgery. However, it may be diagnosed pre operatively due to symptoms of obstruction, volvulus or rarely due to perforation. We present an adult having tubular duplication of ascending colon, that presented with perforation. The duplication had a blind end and did not have distal communication. In addition, it had its own blood supply. The management of the case is discussed. Aetiogenesis of the anomaly is enumerated and literature reviewed. For ascending colon duplication similar meaning word accessory ascending colon has also been used in the manuscript.

Highlights

Examples include gastric/colonic/pancreaticGastro-intestinal duplications are uncommon anomaly
Due to complications of acute abdomen or bowel obstruction, most cases (65-80%) are detected in children by the age of 2 years2,3,4,5,6,7.8. This is the reason that most cases have been reported in children and a few number of cases have been reported in adults
Fotiadis et al stated that most of the time definitive diagnosis of colonic duplication is made during a laparotomy[6]

Summary

Introduction

Due to complications of acute abdomen or bowel obstruction, most cases (65-80%) are detected in children by the age of 2 years2,3,4,5,6,7.8. Patient did not consent for CT abdomen, and with a presumptive diagnosis of volvulus sigmoid colon with perforation emergency exploratory laparotomy was done. The duplicated ascending colon had a blind end distally, that reached pelvic brim It was grossly distended and there was a big perforation at its origin from the primary colon (Figure 1, 2 and 3). The ascending colon was excised from proximal to origin of duplication along with right colonic flexure. AC: Accessory ascending colon, TC: Taenia coli Figure 1: Long duplication of ascending colon with distal free blind end. Contrast MRI have been used in the diagnosis of Type I Simple cyst colonic duplication

Currently laparoscopic resection of colon duplication
