Barbed versus standard suture: a randomized trial for laparoscopic vaginal cuff closure

Area of Science:

• Minimally Invasive Gynecologic Surgery
• Surgical Suturing Techniques
• Female Reproductive Health

Background:

• Laparoscopic total hysterectomy is a common gynecologic procedure.
• Vaginal cuff closure is a critical step influencing patient outcomes.
• Evaluating novel suturing materials like barbed sutures is essential for surgical innovation.

Purpose of the Study:

• To compare the efficacy of barbed versus traditional sutures for vaginal cuff closure during laparoscopic total hysterectomy.
• To assess differences in closure time, cuff healing, and postoperative dyspareunia.
• To evaluate the impact on sexual function at three months post-procedure.

Main Methods:

• Randomized clinical trial (Canadian Task Force classification I) conducted at a university hospital.
• Sixty-three women undergoing total laparoscopic hysterectomy were randomized to barbed (Quill) or standard (Vicryl) suture for vaginal cuff closure.
• Outcomes measured included cuff closure time, cuff healing assessment, and sexual function questionnaires (preoperative and 3-month postoperative).

Main Results:

• Mean vaginal cuff closure times were similar between barbed (10.4 minutes) and standard (9.6 minutes) suture groups (p = .51).
• Cuff healing and rates of dyspareunia, partner dyspareunia, and sexual function were comparable at 3 months postoperatively.
• Attending surgeons achieved significantly faster closure times (7.1 minutes) compared to residents/fellows (12.8 minutes; p < .0001).

Conclusions:

• Barbed sutures offer comparable vaginal cuff closure times and healing to traditional sutures in laparoscopic hysterectomy.
• Neither suture type demonstrated a significant difference in postoperative dyspareunia or sexual function.
• Surgical experience level, not suture type, was a significant factor in closure time.
