Abstract: Objective：To probe into the clinical value of laparoendoscopic single-port surgery(LESS) in the treatment of benign gynecological disease. Methods：68 patients who underwent transumbilical single-port laparoscopic surgery at the gynecological department of our hospital between January 2018 and April 2019 were selected as the research group, and another 70 patients with same diseases who underwent conventional multiple ports laparoscopic surgery were chosen as the control group. The indexes such as intraoperative bleeding volume, highest postoperative body temperature, postoperative time for passage of gas by anus, postoperative out of bed activity time, postoperative hospitalized duration, 24 h postoperative VAS, BIS (body image scale) score and incision aesthetic satisfaction CS score, surgical duration and perioperative complications in both groups were compared. Results：The surgeries for patients in both groups were completed smoothly, no intraoperative assisted manipulation was needed and no conversion to laparotomy was done. No severe intraoperative or postoperative complications occurred. There were no significant differences between the intraoperative bleeding volume, highest postoperative body temperature, postoperative time for passage of gas by anus, postoperative activity time, postoperative hospitalized duration in both groups (P＞0.05). However, the differences between surgical duration, 24 h postoperative VAS among patients，body image scale BIS score and incision aesthetic satisfaction CS score were statistically significant (P＜0.05). Conclusions: The transumbilical single-port laparoscopy with conventional instruments do not need special instruments or devices, which conforms to the characteristics of health economics; it is equipped with good cosmetic effect and the advantage of convenient specimen extraction; the application of LESS in the treatment of benign gynecological diseases is safe and feasible.
