The safety and learning curve of laparoendoscopic single-site technique in female reproductive related surgery

Abstract

Objective To investigate the safety of laparoendoscopic single-site technique in female reproductive related surgery and to describe the short-term learning curve based on the operative time. Methods The clinical data of 42 cases of laparoendoscopic single-site surgery performed by the same surgeon from Sep. 2016 to Dec. 2017 in the Third Affiliated Hospital of Guangzhou Medical University were retrospectively analyzed.The average age was(30.4 ± 4.9)years old(range, 22 - 45). The mean infertility duration was(3.6 ± 3.0) years(range, 1-15 years). The mean BMl was(22.0 ± 3.1)kg/m2 (range, 17.6-31.3) kg/m2.All patients were taken about 1.5-2.0 cm incision through the umbilical access, incision sheath and Port placement, the establishment of pneumoperitoneum after laparoendoscopic single-site equipment and special instrument to complete the female reproductive surgery.To record the change of operation mode, operation complications, intraoperative blood loss, postoperative exhaust time, hospitalization time and other data to explore the safety of laparoendoscopic single-site technique. The learning curve was plotted according to the operation time and the number of cases. Results All 42 cases were successfully completed, no surgical changes in surgery, no bleeding puncture, vascular injury and other intraoperative complications. All patients were followed up for 1-12 months, yet found incision infection, umbilical hernia and other postoperative complications.The average operation time was (73.0 ± 26.9) min, the intraoperative blood loss was (4.5 ± 3.2) ml, the postoperative exhaust time was (1.5 ± 0.6) days and the hospitalization time was(2.5±1.1) days. Observation of learning curve, about 25 cases of surgery, the operation time gradually stable. Conclusions The laparoendoscopic single-site technique in female reproductive related surgery is safe and feasible. To master this technique requires a certain learning curve, and the operation time gradually becomes stable after about 25 cases.
