To the feasibility and safety of "chopsticks technique" for the laparoendoscopic single-site surgery total hysterectomy were confirmed by peroperative outcome was compared with traditional laparoscopic total hysterectomy.

A retrospective cohort study was used in this study. Patients who were included in the laparoendoscopic single-site surgery total hysterectomy and the traditional laparoscopic total hysterectomy of the First Affiliated Hospital of the Army Military Medical University from Dec. 2016 to Jun. 2019. The operation time, intraoperative bleeding amount, postoperative exhaust time, VAS score after surgery (12 h, 24 h), postoperative hospitalization time and postoperative complications of the two groups were compared.

A total of 297 patients were included in the study, including 107 laparoendoscopic single-site surgery (LESS group) and 190 traditional laparoscopic(TL group). Both groups successfully completed the operation, no case was transferred to laparotomy. Baseline values of patients were balanced in both groups. The operation time of the LESS and TL groups were 131 min(102, 155)min and 125.5 min (92.8, 155) min with no statistical difference (P> 0.05); intraoperative bleeding was 100 ml(100, 200)ml and 100 ml(100, 150)ml, no statistical difference (P> 0.05); there were no statistical differences in postoperative exhaust time, VAS score after surgery (12 h, 24 h), postoperative complications (P> 0.05); both groups vaginal stump healed well. The LESS group was shorter postoperative hospital stay than the TL group and was statistically significant (P<0.05). For patients at uterine size≥12 weeks gestation and uterine size<12 weeks gestation were compared, there was no statistical difference between LESS group and TL groups in the operation time, postoperative bleeding time, postoperative exhaust time, VAS score after surgery (12 h, 24 h), perioperative complications (P> 0.05). Among them, for the uterine <12 gestational weeks, The LESS group was shorter postoperative hospital stay than the TL group and was statistically significant (P<0.05).

The perioperative outcome of the "chopstick technique" for laparoendoscopic single-site surgery total hysterectomy was similar to that of traditional laparoscopic total hysterectomy. The feasibility and safety in the laparoendoscopic single-site surgery were preliminarily demonstrated.
