Laparoscopic Radical Colectomy with Complete Mesocolic Excision Offers Similar Results Compared with Open Surgery

Area of Science:

• Colorectal Surgery
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• Complete mesocolic excision (CME) is advocated for colon cancer to enhance local control and survival.
• CME is technically demanding, and laparoscopic CME (Lap-CME) presents greater challenges.
• Laparoscopic surgery offers advantages in colorectal procedures, but Lap-CME requires specialized skills.

Purpose of the Study:

• To evaluate Laparoscopic Complete Mesocolic Excision (Lap-CME) as a standard procedure for colon cancer.
• To compare oncological outcomes of Lap-CME with conventional open CME.
• To assess the feasibility and success rate of Lap-CME in a real-world setting.

Main Methods:

• A standardized medial-to-lateral open or laparoscopic CME technique was used.
• 100 consecutive colon cancer patients were operated on by the same surgical team.
• Perioperative data were prospectively recorded and retrospectively analyzed.

Main Results:

• Laparoscopic CME was performed in 39% of cases across various colectomy types.
• Oncological quality parameters (lymph node count, margins, completeness) were similar between open and laparoscopic groups.
• No significant differences in oncological outcomes were observed based on tumor location or stage.

Conclusions:

• Experienced surgical teams can offer Laparoscopic Complete Mesocolic Excision (Lap-CME) as a standard procedure for selected colon cancer patients.
• Lap-CME provides oncological results comparable to open surgery.
• This approach can potentially improve local disease control and long-term survival in colon cancer treatment.
