Abstract
Objectives: Due to the development of laparoscopy techniques, single-site incision laparoscopic surgery (SILS) has recently been performed at many institutes using only a single-incision transumbilical port. We aimed to carry out a learning curve analysis for SILS for adnexal surgery and validate the short-term surgical outcomes.
Material and methods: In total, 214 patients were enrolled in this study. The medical records of patients who underwent SILS for adnexal surgery by an expert surgeon from October 2008 to September 2018 were reviewed and analyzed.
Results: The mean age and parity were 33.9 ± 11.5 years and 1.0 ± 1.1, respectively. The mean operation duration was 77.5 ± 22.3 min. In the analysis of the learning curve for single-site incision laparoscopic adnexal surgery, surgical proficiency was defined as the point at which the slope of the learning curve became less steep, which was evident after the 24th operation. No operative complications, conversions to laparotomy or additional trocar insertions were observed.
Conclusions: Single-site incision laparoscopic surgery (SILS) for adnexal surgery is a safe technique and does not increase the risk of peri- or postoperative complications. For safe performance of SILS, a certain training period for learning the technique should be required.
