Single‐site robotic cholecystectomy versus single‐incision laparoscopic cholecystectomy: A systematic review and meta‐analysis

Abstract

AbstractBackgroundThe possibilities of minimally invasive cholecystectomy have emerged since the beginning of single‐incision laparoscopic cholecystectomy (SILC) and single‐site robotic cholecystectomy (SSRC). This study aimed to compare the feasibility, safety, and pain scores between SSRC and SILC.MethodsThe authors searched randomized or non‐randomized controlled trials and observational studies in PubMed, EuroPMC, and ClinicalTrials.gov from April 2012 until April 2022. The authors analyzed the operation time, hospital stay, blood loss volume, conversion rate, intraoperative complication rates, postoperative complications, visual analog scale (VAS) immediately after surgery, and VAS at hospital discharge. This study aligned with PRISMA and AMSTAR guidelines.ResultsThirteen studies were selected with 817 and 757 patients who underwent SSRC and SILC. Thus, this study demonstrated a lower incidence of intraoperative complication rates [relative risk (RR) 0.57 (95% CI 0.34–0.96), p = 0.03] and lesser VAS score at hospital discharge [Std. Mean Difference (SMD) −0.23 (95% CI −0.46, −0.01), p = 0.04] in the SSRC group. Regarding operation time and cost, SSRC revealed a longer time [SMD 1.02 (95% CI 0.45, 1.59), p = 0.0004] and higher cost [SMD 4.18 (95% CI 1.77, 6.58), p < 0.00001], respectively. Meanwhile, SSRC did not differ from SILC during a hospital stay, blood loss volume, conversion rate, postoperative complication rates, and VAS immediately after surgery.ConclusionsConcerning intraoperative complication rates and VAS score at hospital discharge, SSRC was superior to SILC. Thus, SSRC is considered a feasible and safe procedure.
