Comparison of 2 Methods of Vaginal Cuff Closure at Laparoscopic Hysterectomy and Their Effect on Female Sexual Function and Vaginal Length: A Randomized Clinical Study

Study objective: To compare the effects of the laparoscopic approach versus the vaginal route for the management of vaginal cuff closure during total laparoscopic hysterectomy on female sexual function in premenopausal patients with benign gynecologic conditions.

Design: A prospective study with a randomized, double-blind design (Canadian Task Force Classification I).

Setting: A university hospital.

Patients: Patients who were scheduled to have total laparoscopic hysterectomy because of benign conditions.

Interventions: Patients were randomized to vaginal cuff closure via the vaginal route versus the laparoscopic approach. The study included a total of 70 patients; 34 underwent the laparoscopic approach in the management of vaginal cuff closure, and 36 underwent the vaginal route.

Measurements and main results: Female sexual function and vaginal length were measured. The duration of total surgery was significantly shorter in the laparoscopic approach group compared with the vaginal route group (112.2 ± 36.5 vs 122.7 ± 53.6, p < .05). The total Female Sexual Function Index scores preoperatively and 3 months postoperatively were similar between the laparoscopic approach and vaginal route groups (all p > .05). Vaginal lengths 3 months postoperatively were significantly longer in the laparoscopic approach group compared with the vaginal route group (8.39 ± 0.90 vs 7.34 ± 1.17, p < .05). The duration of cuff closure was significantly shorter in the vaginal route group compared with the laparoscopic approach group (8.92 ± 2.23 vs 7.51 ± 2.5, p < .05). Preoperative vaginal lengths were significantly longer in comparison with 3 months postoperatively both in the laparoscopic approach and the vaginal route groups (all p < .05). The preoperative total Female Sexual Function Index scores were significantly higher in comparison with 3 months postoperatively both in the laparoscopic approach and the vaginal route groups (all p < .05).

Conclusion: The results of this study indicate that the laparoscopic approach for vaginal cuff closure might be preferable because of better postoperative vaginal length and a shorter duration of total surgery time.
