In this study, 166 patients of benign gallbladder disease were randomized enrolled into two groups and received MRC or DRC (83\u00a0in the MRC group; 83\u00a0in the DRC group). The primary endpoint was surgical success rate. Secondary endpoints were the docking time, console time, total operation time, intraoperative blood loss, gallbladder breakage rate, postoperative pain, time of first flatus, the comprehensive complication index (CCI), and the hospital stay of the subjects. The duration of follow\u2010up was 30\u00a0days.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>No conversion occurred.

The MRC group showed higher postoperative pain scores compared to DRC (4.0 vs 3.0, <jats:italic>P<\/jats:italic>\u2009=\u20090.038). The console time, intraoperative blood loss, and gallbladder breach rate were comparable in these two groups (<jats:italic>P<\/jats:italic>\u2009&gt;\u20090.05).
