Abstract

Introduction: Descending colon and sigmoid colon are parts of the large intestine. The descending colon is situated on the left side of the posterior abdominal wall and the sigmoid colon is situated in the pelvis. The descending colon is retroperitoneal, whereas the sigmoid colon is suspended by a sigmoid mesocolon. This paper reports a case of displaced sigmoid and descending colons. Case Report: During regular dissection classes of the abdomen, a congenital anomaly of the descending colon and sigmoid colon was noted. The descending colon began as a continuation of the left colic flexure and gradually moved to the right on its downward course to reach the midline. It continued as sigmoid colon at the level of the 5th lumbar vertebra. Its upper part gave attachment to the upper part of the mesentery of the small intestine and the lower part was retroperitoneal. It was covered in front by the coils of the small intestine. The sigmoid colon occupied the median position in the lesser pelvis. The sigmoid mesocolon was fan-shaped, extended from the left psoas major muscle to the right side of the posterior pelvic wall. Further, a peritoneal fold extended from the right side of the sigmoid mesocolon to the mesoappendix. This fold did not contain any blood vessels. Conclusion: Anomalies noted here might go unnoticed throughout life or might cause digestive, vascular, and urinary problems. The knowledge of the anomaly is important for radiologists, gynaecologists, and surgeons.
