Comparison of laparoscopy-assisted vaginal hysterectomy as endoscopic single-station surgery and conventional laparoscopic hysterectomy\u2014surgical effects on safety and quality of life

Abstract

BackgroundTo extend the benefits of minimally invasive surgery, an increasing enthusiasm has emerged for the laparo-endoscopic single-site surgery (LESS). The idea of LESS is to allow inserting multiple laparoscopic instruments through only one umbilical incision instead of multiple abdominal incisions.MethodsSixty patients from three different centers in Germany were randomized (1:1) to conventional laparoscopic hysterectomy (n = 31) or LESS hysterectomy (n = 29). The study focused in particular on the safety and efficacy of both techniques.ResultsThe mean operative time was comparable in both groups (68.2 vs 73.6 min., p = 0.409; 95% CI − 18.69–7.12). No differences were seen regarding estimated blood loss (p = 0.915; 95% CI − 21.02–18.88), intra- and postoperative complications (p = 0.944), and wound infection rates (p = 0.944). Patients within the LESS group experienced significantly less pain in the first 24 h postoperatively (p = 0.006); the pain scores at 3, 5, 7 days and 2 months postoperatively were comparable.ConclusionLESS hysterectomy is a reliable and safe option in gynecologic surgery. Compared to conventional laparoscopic hysterectomy, LESS surgery demonstrated comparable surgical properties in regard to blood loss, duration of surgery, and intra-/postoperative complications. Notably, patients undergoing LESS hysterectomy experienced some less pain postoperatively.
