Abstract

A 55-year-old-man underwent laparoscopic sigmoidectomy for sigmoid colon cancer. Preoperative barium enema showed a slightly medial displacement of the descending colon, and the sigmoid colon was quite long. The operative findings showed that the descending colon was not fused with the retroperitoneum and shifted to the midline and the left colon adhered to the small mesentery and right pelvic wall. Thus, a diagnosis of persistent descending mesocolon (PDM) was made. The left colon, sigmoid colon, and superior rectal arteries often branch radially from the inferior mesenteric artery. The sigmoid mesentery shortens, and the inferior mesenteric vein is often close to the marginal vessels. By understanding the anatomical feature of PDM and devising surgical techniques, laparoscopic sigmoidectomy for sigmoid colon cancer with PDM could be performed without compromising its curative effect and safety.
