Abstract

Background: Single-incision robotic cholecystectomy (SIRC) is widely performed with both the da Vinci Xi system (Xi) and the da Vinci SP system (SP). But there are limited numbers of studies comparing these platforms. Methods: Patients who underwent SIRC between 2019 and 2020 were enrolled. Patient demographics, intraoperative factors, postoperative complications, postoperative pain were compared using a one-to-one propensity score matching (PSM). Results: Overall, 258 patients underwent SIRC with Xi and 72 with SP. After PSM, there were significant differences between the Xi and SP in operation time at console and numeric rating scale for postoperative pain, but no difference in total operation time and postoperative complications. The SP group showed more estimated blood loss. Conclusions: Despite the statistical difference, clinical benefit was not significant. Both platforms can be safe and feasible to perform SIRC, but further investigation including the surgeon's workload and ergonomics is needed as a prospective study.
