Introduction : Minimally invasive cholecystectomy is now standard treatment, meanwhile there is still debate of which platform is more convenient and practical for patients and surgeon both. The da Vinci system has recently released a true single-port platform, the da Vinci SP system (RSPC), with all the instruments entering into one single port. We compared da Vinci SP cholecystectomy and other minimally invasive reduced-port cholecystectomy platform.

Methods : Since our center started RSPC in May 2019, 70 cases of RSPC were underwent. We compared 70 cases of RSPC and 94 cases of da Vinci single-site cholecystectomy (RSSC) and 105 cases of laparoscopic single-fulcrum cholecystectomy (LSFC) each group.

Results : In terms of perioperative outcome, there was significant difference between total operative time (mean±SD) (RSPC 75.0±19.0 vs RSSC 91.1±27.3 vs LSFC 56.7±14.1 min), actual dissection time (RSPC 16.5±8.4 vs RSSC 22.9±17.1 vs LSFC 24.9±11.8 min). Docking time ( RSPC 5.1±2.0 vs RSSC 9.8±4.4 min) and console time (RSPC 34.6±13.2 vs RSSC 42.5±21.2 min) showed significant differences. There were no significant difference between two groups regarding conversion rate, hospital stays, bile spillage rate during surgery and postoperative complications.

Conclusions : RSPC can be performed safe and feasible. RSPC showed comparable perioperative outcome (hospital stay, postoperative complication rate, bile spillage during surgery, multiport-conversion rate) and showed shorter docking time and actual dissection time compared with RSSC. This benefit may be helpful in beginner for single-incision cholecystectomy. In future, RSPC can be used in pancreatic mass enucleation, distal pancreatectomy, etc.
