Layer-Oriented Lateral Superior Approach for Robotic Right Hemicolectomy: A Novel Embryology-Based Strategy and Initial Clinical Outcomes

Background

Complete mesocolic excision (CME) with D3 lymphadenectomy is an oncologically established procedure for right-sided colon cancer; however, the optimal dissection plane and surgical approach remain controversial. We developed a novel layer-oriented lateral superior approach (LSA) that enables the intentional, depth-tailored selection of embryological dissection planes in robotic right hemicolectomy.
