A randomized clinical trial comparing the initial vascular approach to the inferior mesenteric vein versus the inferior mesenteric artery in laparoscopic surgery of rectal cancer and sigmoid colon cancer.

In our study, the initial approach by the IMV with a systematic MM of the splenic flexure has allowed us to reduce the conversion rate without increasing complications or the surgical time. No differences were observed in the pathological results. Both approaches seem to be safe and effective and well-trained laparoscopic surgeons should have the two techniques available to them for use as needed.
