[Standard procedure for colon cancer resection:complete mesocolic excision]

Area of Science:

• Colorectal surgery
• Surgical oncology
• Gastrointestinal oncology

Context:

• Colon cancer surgery requires standardized techniques for optimal outcomes.
• Current surgical approaches may vary, impacting lymph node yield and oncological safety.
• Complete Mesocolic Excision (CME) has emerged as a proposed standardized method.

Purpose:

• To define and explain the principles of Complete Mesocolic Excision (CME).
• To highlight the oncological advantages of CME in colon cancer surgery.
• To assess the current understanding of CME's impact on patient survival and surgical quality.

Summary:

• CME involves sharp dissection along the visceral fascial plane, mobilizing the entire mesocolon with intact fascial layers.
• This technique ensures central vascular ligation at the origin and maximizes regional lymph node harvest.
• Key oncological benefits include reduced risk of tumor spread via lymphovascular invasion and improved lymph node yield.

Impact:

• CME demonstrates significant survival benefits for patients with stage III colon cancer.
• Further studies are required to evaluate CME's efficacy in other cancer stages.
• The feasibility and outcomes of laparoscopic CME require additional investigation.
