Comparative analysis of postoperative outcomes of single-incision cholecystectomy: Propensity score matching of robotic surgery using the da Vinci SP system and da Vinci Xi system vs. laparoscopic surgery

Abstract

Backgrounds/Aims: We compared the postoperative outcomes of single-incision laparoscopic cholecystectomy (SILC) with those of single-incision robotic cholecystectomy (SIRC) using the da Vinci Xi and SP systems. Methods: We retrospectively analyzed data from 206 patients who underwent these procedures by a single surgeon between August 2020 and April 2022. Propensity score matching was used to adjust for confounders and evaluate outcomes. Results: < 0.001). Pain scores and complications did not significantly differ between the groups. Conclusions: Both SILC and SIRC showed comparable outcomes, with the SP system providing advantages such as reduced console time and fully articulated arms, likely reducing surgeon stress.
