Comparison of pathologic outcomes of robotic and open resections for rectal cancer: A systematic review and meta-analysis.

ABSTRACT:

Objective

The application of robotic surgery for rectal cancer is increasing steadily. The purpose of this meta-analysis is to compare pathologic outcomes among patients with rectal cancer who underwent open rectal surgery (ORS) versus robotic rectal surgery (RRS).

Methods

We systematically searched the literature of EMBASE, PubMed, the Cochrane Library of randomized controlled trials (RCTs) and nonrandomized controlled trials (nRCTs) comparing ORS with RRS.

Results

Fourteen nRCTs, including 2711 patients met the predetermined inclusion criteria and were included in the meta-analysis. Circumferential resection margin (CRM) positivity (OR: 0.58, 95% CI, 0.29 to 1.16, P = 0.13), number of harvested lymph nodes (WMD: -0.31, 95% CI, -2.16 to 1.53, P = 0.74), complete tota
