Novel approach toward minimally invasive surgery for mid‐transverse colon cancer: ‘moving the left colon’ technique

Abstract

AbstractAimDuring surgery for mid‐transverse colon cancer (MTC), surgeons often face the dilemma of whether to mobilize the hepatic or splenic flexure. There is no established optimal minimally invasive surgical procedure for MTC.MethodsWe present our novel minimally invasive surgical technique, called the ‘moving the left colon’ technique for MTC, along with a video demonstration. The procedure involves four main steps: (i) mobilization of the splenic flexure using a medial‐to‐lateral approach, (ii) dissection of lymph nodes around the middle colic artery from the left side of the superior mesenteric artery approach, (iii) separation of the pancreas and transverse mesocolon and (iv) ‘moving the left colon’ and performing an intracorporeal anastomosis. By mobilizing the splenic flexure, anatomical landmarks are revealed, which enables safer dissection. Combining this technique with intracorporeal anastomosis allows for a safe and easy anastomosis.ResultsBetween April 2021 and January 2023, a single‐skilled colorectal surgeon performed laparoscopic transverse colectomies using our new approach on three consecutive patients with MTC. The patients had a median age of 75 years (range 46–89 years). The median operative time was 194 min (range 193–228 min) and blood loss was 8 mL (range 0–20 mL). None of the patients experienced any perioperative complications and the median postoperative hospital stay was 6 days.ConclusionWe introduced a novel approach for laparoscopic surgery for MTC. This technique can be performed safely and may help standardize minimally invasive surgery for MTC.
