Gasless robotic single-port cholecystectomy using the DaVinci SP system: A feasible way to minimise surgical derangement while obtaining critical view of safety.

Abstract

The aim of this study was to present our initial experience of gasless robotic single-port cholecystectomy (RSPC). We reviewed 48 patients who underwent gasless RSPC with a da Vinci SP Robotic Surgical System. Demographic data, intra-operative results, and postoperative outcomes were evaluated. Gasless RSPC was successfully performed in 48 of 53 patients. Five patients had conversion to standard pressure pneumoperitoneum due to insufficient surgical space (n=3), GB perforation (n=1), or bleeding during surgery (n=1). The mean whole operation time was 53.6±17.2min. No patients complained of postoperative shoulder pain or had any postoperative complications. The average hospital stay was 2.1±0.3days. Gasless RSPC is feasible and safe. The unique features of an SP robotic platform allow surgeons to perform safely in an incapacious surgical space. However, this procedure is currently only possible for highly selected patients.
