Aims: The aim of this study was to investigate the technical feasibility, safety, and benefit of single-port laparoscopic cholecystectomy (SPLC) by retrospective comparision with conventional multi-port laparoscopic cholecystectomy (MPLC).
Methods: Between August 2015 and April 2016, hundred patients underwent laparoscopic cholecystectomy by one surgeon. SPLC was introduced and performed in 43 patients for benign gallbladder disease (SPLC), fifty seven patients underwent MPLC (MPLC group). We retrospectively reviewed the clinical features and outcomes between the two groups.
Results: All of 43 patients had successfully completion of SPLC (100%) without conversion. The age was similar between the two groups (p = 0.433). There was no significant difference between the two groups regarding patient body mass index (p = 0.336), history of previous abdominal surgery (p = 0.088), history of preoperative endoscopic retrograde cholangiopancreatography (ERCP) (p = 0.812), history of percutaneous drainage (p = 1.000), and ASA score (p = 0.132). There were no statistical differences between the two groups in term of operative time (p = 0.339), postoperative complication (p = 1.000), the length of postoperative hospital stay (p =0.580), and pain score (p = 0.350).
Conclusions: In this study, SPLC has been successfully performed for benign gallbladder disease and the safety and feasibility was also confirmed. Although this study is retrospective and not large enough to provide definitive conclusion that SPLC may be equal to MPLC in term of safety and feasibility, SPLC may become an effective alternative option to MPLC for the treatment of benign gallbladder.
