A comparison of barbed and smooth sutures for ovine cesarean delivery

Objective To determine the adequacy of barbed and smooth sutures for closing the uterus and fascia in pregnant ewes. Methods Nine ewes that underwent cesarean delivery were randomized to each receive 2 different suture materials for both the uterus and the fascia. The sutures used were: barbed poliglecaprone 25, smooth poliglecaprone 25, braided polyglactin 910, and smooth chromic sutures on the uterus; and barbed polydioxanone (PDO), barbed poliglecaprone 25, braided polyglactin 910, and smooth chromic sutures on the fascia. Results In 4 of the ewes, the fascia suture line failed prematurely, leading to dehiscence prior to planned euthanasia and necropsy. The remaining 5 ewes were euthanized on days 2, 7, or 28. All suture materials (smooth and barbed) were adequate for uterine closures. Barbed PDO, smooth poliglecaprone 25, and braided polyglactin 910 were adequate for fascia closures, whereas both barbed poliglecaprone 25 and smooth chromic resulted in premature suture line ruptures and fascia dehiscence. Conclusion In a small pilot study, absorbable knotless barbed suture was adequate and equivalent to absorbable knotted smooth suture for closing the uterus following ovine cesarean delivery. On the rectus fascia, however, sutures—whether barbed or smooth—with lower tensile strength resulted in fascial dehiscence.

Use of Bidirectional Barbed Suture in Laparoscopic Myomectomy: Evaluation of Perioperative Outcomes, Safety, and Efficacy

Study Objective To compare perioperative outcomes during laparoscopic myomectomy using a bidirectional barbed suture vs conventional smooth suture. Design Retrospective analysis of 138 consecutive laparoscopic myomectomies performed by a single surgeon over 3 years (Canadian Task Force classification II-2). Setting Major university teaching hospital. Patients One hundred thirty-eight women with symptomatic uterine myomas. Interventions In women undergoing laparoscopic myomectomy from February 2007 through April 2010, conventional smooth sutures were used in 31 patients, and bidirectional barbed suture in 107 patients. Measurements and Main Results The primary indications for laparoscopic myomectomy in either group were pelvic pain or pressure and abnormal uterine bleeding. Use of bidirectional barbed suture was found to significantly shorten the mean (SD) duration of surgery (118 [53] minutes vs 162 [69] minutes; p <.05) and reduce the duration of hospital stay (0.58 [0.46] days vs 0.97 [0.45] days; p <.05). No significant differences were observed between the 2 groups insofar as incidence of perioperative complications, estimated blood loss, and number or weight of myomas removed during surgery. Conclusion Use of bidirectional barbed suture seems to facilitate closure of the hysterotomy site in laparoscopic myomectomy.
