Updated Overview about Laparoscopic Right Hemicolectomy for Colon Cancer

Abstract

Background: Laparoscopic right hemicolectomy (LRH), a common procedure for right-sided colon cancer, faces ongoing challenges regarding its application, techniques, and overall trends. This review aims to analyze the current state of LRH by examining key issues surrounding the surgery.

Existing research suggests that LRH likely offers better short-term outcomes while achieving comparable cancer control compared to traditional open surgery. While robotic-assisted surgery is gaining traction, it tends to be associated with longer operating times and higher costs with limited additional benefits. Intracorporeal anastomosis, a technique where the connection is made inside the body, seems to improve early recovery (like faster bowel function) compared to extracorporeal anastomosis, where the connection is made outside the body. However, intracorporeal anastomosis doesn't always translate to a shorter hospital stay. Dissection techniques, including different approaches and landmarks, have been proposed to overcome the technical challenges inherent to LRH. These challenges are often rooted in anatomical variations, particularly in venous structures. While various methods have been suggested, large-scale prospective studies are needed to definitively determine the superiority of one approach over another. Ultimately, a deep understanding of both anatomical variations and the specific characteristics of each approach is crucial for minimizing complications and maximizing patient well-being after LRH.
