Laparoscopic extended right hemicolectomy with D3 lymphadenectomy

Laparoscopic extended right hemicolectomy with D3 lymphadenectomy has been recognized as the most challenging surgery among all colon procedures. This surgery involves an extensive scope and a number of important organs, where a clear understanding of the superior mesenteric vein (SMV) anatomy is needed to complete the thorough dissection. It is not only demanding for the surgeon, but also associated with a high requirement for the cooperation by the assistant and camera operator. The slightest mistake may result in failure to achieve complete mesocolic excision (CME) and D3 lymphadenectomy, or even damage to the ureter, duodenum and other vital organs, or worse, superior mesenteric arteriovenous damange directly leading to fatal bleeding. We have accumulated the experience of experts from multiple centers across the country, and summed up with some of our own experience in this study to share with you.
