A comparison of laparoscopically assisted and open colectomy for colon cancer. Nelson H, Sargent DJ, Wieand HS, Fleshman J, Anvari M, Stryker SJ, et al.
A comprehensive preoperative knowledge of the branching patterns of the middle colic artery and left colic artery and the presence of collateral arteries would be helpful in surgery for colon cancer in the splenic flexure.Īccessory middle colic artery Anatomy Left colic artery Riolan’s arch Splenic flexure. The frequency was found to vary widely across studies, partially due to the ambiguous definition of Riolan's arch. The reported frequency of Riolan's arch was 7.5-27.8%. The accessory middle colic artery was present in 6.7-48.9% of cases and was present in > 80% of cases without a left colic artery. The left colic artery was absent in 0-7.5% of cases. The middle colic arteries were reported to arise independently without forming a common trunk in 8.9-33.3% of cases.

After screening of full texts, 33 studies were selected. We searched the PubMed database for studies on the vascular anatomy of the splenic flexure that were published from January 1990 to October 2020. We reviewed the patterns of vascular anatomy and the definition of the vessels around the splenic flexure. Surgical treatment of the transverse colon is difficult because of the many variations of blood vessels.
