Prospective randomized controlled trial of traditional laparoscopic assissted vaginal hysterectomy versus SILS™ Port laproscopic assisted vaginal hysterectomy

  • Background/Aim: Laparoscopic single-port surgery has emerged as a growing trend in minimally invasive surgery. Single-port access is preferred among women undergoing gynecologic surgery who have cosmetic concerns about scarring. Furthermore, this approach results in comparable clinical outcomes to standard laparoscopic surgery and perioperative morbidity rates have been reported to be low. The hypothesis is that a single-port technique might offer such advantages over the standard multi-port laparoscopy as less postoperative pain and better cosmetic results by decreasing abdominal wall tissue trauma. The potential disadvantages of single-port approaches are the larger umbilical incision and the technical difficulties. There are only a few randomized studies in the literature that investigate the value and safety of single-incision laparoscopic surgery in gynecological surgery. The aim of this study was to compare the safety and quality of life in patients who undergo single-incision laparoscopic assisted vaginal hysterectomy and those who undergo conventional laparoscopic assisted vaginal hysterectomy. Methods: In a prospective randomized trial, 64 patients from three different centers in Germany were randomized (1:1) to conventional laparoscopic assisted vaginal hysterectomy (n=32) or single-incision laparoscopic assisted vaginal hysterectomy (n=30). Data was collected on 60 patients who fulfilled the criteria. Results: The baseline characteristics of patients were similar in both groups. The mean operative time was comparable in both groups (68.2 vs 73.6 min., p = 0.409). Within the two groups, no differences were seen regarding estimated blood loss (p = 0.915), intra- and postoperative complications (p = 0.944), and wound infection rates (p = 0.944). Patients within the single-incision laparoscopic surgery group experienced significantly less pain in the first 24 hours postoperatively (p = 0.006), while pain scores at days 3, 5, 7 and 2 months postoperatively were comparable. Conclusion: This study demonstrates that single-incision laparoscopic assisted vaginal hysterectomy is a reliable and safe setup in gynecologic surgery. Compared to conventional laparoscopic assisted vaginal hysterectomy, Notably, patients undergoing single-incision laparoscopic assisted vaginal hysterectomy experienced less pain postoperatively.
