Knotless Barbed Sutures Cut Hysterectomy Vault Closure Time to 10 Minutes, Suggests Study
A recent retrospective cohort study published in The Journal of Obstetrics and Gynecology of India in July 2026 reveals that knotless barbed sutures significantly streamline minimally invasive hysterectomy, cutting vaginal vault closure time to 10.28 minutes. Moreover, this self-anchoring thread lowers post-procedural complications, reducing secondary bleeding to 2.88% and granuloma formation to 1.92%.
Vaginal vault re-approximation represents a pivotal phase during MIH where suture selection directly affects operative efficiency and patient outcomes, yet conventional polyglactin sutures present technical knot-tying constraints that self-anchoring materials attempt to resolve. Addressing this clinical gap regarding procedural speed, morbidity, and degradation kinetics, Aruna Tantia, Shashi Khanna, Kalyani Barde, and Kajari Majumdar conducted this study to evaluate barbed against non-barbed sutures for vault closure.
Therefore, the retrospective cohort study evaluated 204 women undergoing laparoscopic or robotic hysterectomy between July 2016 and April 2024, comparing non-barbed Vicryl-1 (n=100) against barbed V-Loc 1-0 (n=104) sutures for vaginal vault closure. Researchers assessed closure duration, postoperative complications, and material absorption over a 12-week follow-up period.
Key Clinical Findings of the Study Includes:
- Enhanced Suturing Speed: Investigators observed that mean vaginal vault closure time was significantly reduced in the barbed suture cohort compared to the non-barbed group (10.28 ± 1.94 minutes vs. 12.69 ± 3.31 minutes; p < 0.0001).
- Reduced Secondary Hemorrhage: Researchers noted a statistically significant drop in post-procedural bleeding rates among patients receiving barbed sutures relative to conventional materials (2.88% vs. 12.00%; p = 0.0126).
- Lower Granuloma Incidence: Authors documented a lower frequency of vault granuloma formation with knotless barbed sutures than with standard polyglactin sutures (1.92% vs. 10.00%; p = 0.0142).
- Extended Suture Resorption: Analysts recorded delayed material degradation with barbed threads, demonstrating only 43.26% absorption at 12 weeks postoperatively compared to complete absorption of vicryl sutures by 10 weeks.
- Minimal Cuff Dehiscence: Data revealed that a single case of vaginal cuff separation occurred exclusively within the non-barbed control arm.
The results suggest that self-anchoring barbed sutures significantly improve surgical efficiency by shortening vault closure time to 10.28 minutes while simultaneously decreasing secondary hemorrhage to 2.88% and vault granuloma to 1.92%. Nevertheless, clinicians must account for extended material degradation, given that only 43.26% of barbed sutures dissolved by 12 weeks, in contrast to full absorption of conventional polyglactin by week 10.
Thus, the study concludes surgeons performing MIH can adopt knotless barbed materials to optimize intraoperative efficiency and reduce postoperative tissue complications, provided patients are appropriately advised regarding the prolonged absorption timeline of the material.
While the observational cohort design inherent to this retrospective review presents potential confounding factors, conducting prospective randomized investigations could further clarify long-term tissue responses and optimize patient management protocols.
