Robotic Right Colectomy with Modified Complete Mesocolic Excision: Long-Term Oncologic Outcomes

Area of Science:

• Surgical Oncology
• Gastrointestinal Surgery
• Robotic Surgery

Background:

• Modified complete mesocolic excision (mCME) shows promise for right-sided colon cancer.
• Robotic colectomy offers potential advantages in minimally invasive surgery.

Purpose of the Study:

• To evaluate the safety, feasibility, and efficacy of robotic right colectomy using the mCME technique.
• To assess short-term outcomes and 4-year oncologic results.

Main Methods:

• Retrospective analysis of 100 consecutive patients undergoing robotic right colectomy with mCME.
• Data collected included intraoperative and postoperative outcomes, pathologic findings, and survival rates.
• Follow-up period of 48.5 months (median).

Main Results:

• Successful completion of robotic right colectomy with mCME in all patients.
• No intraoperative complications or conversions to open surgery.
• Major complication rate of 4%; 4-year survival rates: disease-specific 94.5%, disease-free 91.4%, overall 90.3%.

Conclusions:

• Robotic right colectomy with mCME is a feasible and safe approach for right-sided colon cancer.
• The technique demonstrates satisfactory short-term outcomes and promising long-term oncologic results.
• Randomized controlled trials are recommended to validate the benefits of mCME before routine adoption.
