Robotic single-site versus laparo-endoscopic single-site surgery for adnexal tumours: a propensity score-matching analysis.

Background: The aim of this study was to compare the surgical outcomes of robotic single-site (RSS) and laparo-endoscopic single-site (LESS) surgery for adnexal tumours and evaluate the feasibility of RSS surgery.

Methods: RSS surgery was performed using the da Vinci Single-Site® surgical platform and LESS surgery using a single multi-channel port system. Surgical outcomes were compared between RSS (n = 20) and LESS (n = 228) after 1:4 propensity score matching.

Results: After the propensity score matching, the RSS group showed longer operating times than the LESS (91.1 vs 66.1 min; p = 0.001). While the LESS showed 1.3% of major complication rates, the RSS group had no perioperative complication. For the LESS, 2.5% of patients needed additional port insertion.

Conclusions: The RSS surgery for adnexal tumours could be performed safely without complications or additional port insertion. Although it showed a longer operating time, further experience and technical refinements will continue to improve operative results. Copyright © 2015 John Wiley & Sons, Ltd.
