INTRODUCTION: The usefulness of single-port laparoscopic cholecystectomy (SPLC) as compared to multi-port laparoscopic cholecystectomy (MPLC) remains controversial. Between SPLC and MPLC, we compared outcomes, especially subjective aspects, such as quality of life (QoL).

MATERIAL AND METHODS: This multi-center study, involving 20 institutions from 2016 to 2017, enrolled 2507 patients who underwent laparoscopic cholecystectomy. Various perioperative outcomes, pain assessed by the numeric rating scale (NRS) score, and QoL evaluated by the gastrointestinal QoL index (GIQLI) questionnaire, were compared between the two procedures. We generated balanced groups after propensity score matching (PSM) using preoperative factors that influence the decision to perform MPLC or SPLC.

RESULTS: MPLC and SPLC were performed in 2176 and 331 patients, respectively. Nine hundred and twelve and 329 patients, respectively, were selected from the two groups by PSM. Operation time was longer and surgical difficulty was lower in SPLC. There were no significant differences in most outcomes, including biliary complications. Significant superiority of SPLC over MPLC was shorter hospitalization, lower NRS score, and favorable GIQLI.

CONCLUSIONS: From nationwide prospective data, SPLC showed outcomes comparable to MPLC. In SPLC, morbidity was not high and postoperative QoL was favorable. In the future, more implementations and studies are needed to ensure the safety and feasibility of SPLC.
