Robotic versus laparoscopic proctectomy for rectal cancer: a meta-analysis

Area of Science:

• Surgical Oncology
• Minimally Invasive Surgery
• Robotic Surgery

Background:

• Robot-assisted laparoscopic surgery is increasingly utilized for minimally invasive rectal cancer treatment.
• A need exists to compare its safety and efficacy against conventional laparoscopic surgery.

Purpose of the Study:

• To conduct a meta-analysis comparing robot-assisted versus conventional laparoscopic surgery for rectal cancer.
• To evaluate and compare clinical and oncologic outcomes between the two surgical approaches.

Main Methods:

• Systematic search of Medline and Embase databases for comparative studies.
• Meta-analysis using a random effects model, evaluating conversion rates, operation times, hospital stay, complications, margin status, and lymph node yield.
• Critical assessment of methodological quality for study inclusion.

Main Results:

• Seven studies involving 353 robot-assisted and 401 conventional laparoscopic proctectomy cases were analyzed.
• Robot-assisted surgery demonstrated a significantly lower conversion rate (P=0.03).
• No significant differences were observed in complications, margin status, lymph node yield, or hospital stay.

Conclusions:

• Robot-assisted surgery reduces conversion rates compared to conventional laparoscopic surgery for rectal cancer.
• Clinical and oncologic outcomes are equivalent between the two methods.
• Potential population-specific benefits of robotic rectal cancer surgery warrant further investigation.
