Laparoscopic colorectal surgery for cancer is nowadays routinely performed worldwide. After the introduction by Heald of total mesorectal excision for rectal cancer, also a complete mesocolic excision has been advocated as an essential surgical step to improve oncologic results in patients with colon cancer. The complete removal of mesocolon with high ligation of the main mesenteric arteries and veins and the mobilization of splenic flexure are well-known but still debated in western surgical society. The authors reviewed the literature and outlined the rationale and the results of splenic flexure mobilization and complete mesocolic excision in laparoscopic surgery for colorectal cancer.

Although well established, laparoscopic surgery for ascending colon cancer is a difficult procedure due to the presence of many blood vessels requiring treatment and the need for sufficient mobilization to extract the right colon through a small laparotomy. This is the first study to investigate the adequacy of vascular ligation and bowel mobilization for laparoscopic resection of ascending colon cancer and extracorporeal reconstruction. This retrospective study included 103 consecutive patients who underwent laparoscopic colectomy for ascending colon cancer from 2015 to 2022 at the Center Hospital of the National Center for Global Health and Medicine.

Background/objectives: Complete mesocolic excision (CME) has recently been proposed as a radical operation for the treatment of colon cancer. Increasing evidence suggests a survival benefit from this operation, although the exact reasons for this remain largely unknown.
Methods: We have undertaken a comprehensive review of the literature in PubMed and Embase databases, examining the potential mechanisms explaining this oncologic benefit.

Background: Complete mesocolic excision (CME) for right-sided colon cancer offers oncological advantages but remains technically demanding, which limits its widespread adoption. Understanding the learning curve (LC) for this complex procedure is essential to ensure safe implementation and to guide structured surgical training. This systematic review aims to evaluate the learning curve of minimally invasive CME for right-sided colon cancer, focusing on operative metrics and complications, and estimating the number of cases required to achieve proficiency.

Background: Optimal extent of lymph node dissection for colon cancer is debatable. Extensive lymphadenectomy may increase complication rate, while limited lymph node dissection may compromise oncological outcome. One of promising ways to find balance is to tailor extent of lymph node dissection to patient's individual anatomy using ICG lymphatic mapping.
