Comparison of transvaginal and transumbilical laparoscopic single-site surgery for ovarian cysts

Abstract

Background: Minimally invasive surgery is currently a preferred treatment for symptomatic ovarian cyst(s), with single-site techniques, such as transumbilical laparoendo-scopic single-site surgery (TU-LESS) and transvaginal lap-aroendoscopic single-site surgery (TV-LESS), gaining increasing popularity. Although both methods have deliv-ered positive outcomes, there is currently limited literature directly comparing TU-LESS and TV-LESS. Objectives: This study had two primary objectives: (1) to evaluate the safety and feasibility of TV-LESS and TU-LESS for the treatment of ovarian cysts and (2) to compare the surgical and postoperative outcomes of the two procedures. Method: This was a prospective observational clinical analysis of 81 patients with a diagnosis of benign ovarian cyst with indication for TV-LESS or TU-LESS. Surgeries were performed at a tertiary hospital between February 1, 2018 and January 31, 2020. Patients were divided into TV-LESS (n = 40) and TU-LESS groups (n = 40), with one excluded due to severe pelvic adhesive disease. Demographics, operation outcomes, and follow-up details were compared. Results: All 80 patients underwent uncomplicated proce-dures. The two groups were demographically matched (except age), with no difference in operation time, intra-operative blood loss, hemoglobin loss, and hospitaliza-tion costs (P > 0.05). However, TV-LESS patients had sig-nificantly faster time to ambulation (P < 0.001), faster time to return of bowel function (P < 0.001), less postoperative pain level (P < 0.001), and shorter length of hospital stay (P < 0.001). The cosmetic scores at 1, 4, and 24 weeks after surgery were also higher for the TV-LESS group. Conclusion: Our preliminary experience suggested that TU-LESS and TV-LESS are both feasible and safe for ovarian cystectomy and salpingo-oophorectomy. However, TV-LESS may provide three main advantages including: (1) fewer postoperative complications (i.e. incisional her-nia); (2) less postoperative pain; and (3) improved cosmetic satisfaction.
