Clinical Comparison of 5mm Mini-incision Laparoendoscopic Single-Site Hysterectomy and Traditional Laparoendoscopic Single-Site Hysterectomy

Objective: To investigate the feasibility of 5mm mini-•incision Laparoendoscopic Single-Site hysterectomy and Laparoendoscopic Single-Site hysterectomy in terms of safety, postoperative pain and cosmetic effect. Methods: The medical records of 19 patients who underwent hysterectomy with 5mm mini-•incision Laparoendoscopic Single-Site Surgery (LESS) or traditional Laparoendoscopic Single-Site Sugery in the Affiliated Changzhou No. 2 People’s Hospital of Nanjing Medical University from December 2017 to June 2020 were retrospectively analyzed, including 6 cases in the group of 5mm mini-•incision Laparoendoscopic Single-Site hysterectomy through umbilical ordinary incision (5mm) and 13 cases in the group of traditional Laparoendoscopic Single-Site hysterectomy through umbilical ordinary incision (1.5cm-3cm). Collect and compare the intraoperative blood loss, the operative time, the postoperative hemoglobin descender, the postoperative hospital stays, the probability of postoperative wound infection, the total cost, Visual analogue scale (VAS) of 12 hours after surgery, VAS of 24 hours after surgery and postoperative Body Image Questionnaire (BIQ, including Body Image scale, BIS and Cosmetic Score, CS) in the two groups. Results: There was no intraoperative complication happened, and there was no significant difference between the two groups in the forms of the intraoperative blood loss, operative time, postoperative hospital stays, postoperative hemoglobin descender, the probability of postoperative wound infection, the total cost, VAS of 24 hours after surgery and CS (P > 0.05). But the VAS of 12 hours after surgery of the 5mm mini-•incision Laparoendoscopic Single-Site hysterectomy was lower than traditional Laparoendoscopic Single-Site hysterectomy (1.17±0.14 vs. 2.33±0.19), the BIS of the former was higher than the later (19.83±0.15 vs 19.16±0.28), and importantly the difference was statistically significant (P < 0.05). Conclusion: Laparoendoscopic Single-Site through 5mm mini-incision is safe and feasible. Compared with traditional Laparoendoscopic Single-Site Hysterectomy through ordinary incision, it can not only significantly reduce postoperative pain, but also bring more satisfactory postoperative cosmetic effect.
