Comparison of Laparoscopic Closure of the Bladder with Barbed Polyglyconate Versus Polyglactin Suture Material in the Pig Bladder Model: An Experimental In Vitro Study

Abstract

For the first time, we demonstrated laparoscopic knotless closure of bladder defects using the barbed polyglyconate suture material in an experimental in-vitro model. Closing the pig bladder with running knotless barbed suture provides a more effective and faster watertight bladder closure than traditional polyglactin 910 suture material.

RETRACTED ARTICLE: Use of Barbed Sutures in Bariatric Surgery. Review of the Literature

“…Both intracorporeal and extracorporeal knot-tying require significant training, but even with that it has been observed that knots performed laparoscopically are often less safe than those hand-sewn [7]. In cases where knot-tying is difficult or under certain circumstances that so require it, the use of barbed sutures may reduce operative time [8][9][10], surgeon fatigue, and, potentially, the costs [11].…”

“…In 2012, Gozen et al [8] tested the superiority of barbed sutures regarding suture tightness in a series of porcine bladder closures. After closure of the bladder defect with barbed and non-barbed sutures, it was found using cystometry that the bladder volume required for a leak was larger in the closures with barbed sutures (419.7 ml) than with non-barbed running sutures (353.1 ml) or loose stitches (276.2 ml).…”

Single layer cystotomy closure of excised porcine bladders with barbed versus smooth suture material

“…Barbed suture material was initially developed for tendon repair, consequently evaluated for closure of arthrotomies, and has been applied extensively in plastic and reconstructive surgery in humans . Barbed suture is also well established in laparoscopic and robotic surgery in man, for fast and secure apposition of a variety of tissues . One of these suture devices includes an end loop through which the suture needle is passed after the first tissue bite, eliminating the need for knot tying (Figure ) .…”

“…Although several studies in animals have compared barbed to smooth suture in various applications, only 3 have evaluated its use in cystotomy closure, 2 of those involving laparoscopic closure. Gozen et al compared single layer simple interrupted or continuous closure with size 3‐0 polyglactin 910 to continuous closure with 3‐0 barbed polyglyconate sutures in excised porcine bladders sutured in a laparoscopic trainer box . A recent study by Ruzickova et al compared a 2‐layer inverted closure of equine urinary bladders with size 2‐0 monofilament poliglecaprone 25 to 2‐0 V‐Loc 90 (a copolymer of glycolide, dioxanone, and trimethylene carbonate) knotless, barbed suture .…”

Uso de las suturas barbadas en cirugía general y digestiva. Revisión de conjunto

“…Comprobaron como la fuerza aplicada para conseguir la dehiscencia fue mayor en la sutura barbada, que provocó incluso el desgarro del tejido má s que la rotura de la propia sutura. En 2012, Gozen et al 7 comprobaron la superioridad de la sutura barbada en la estanqueidad de la sutura en una serie de cierre de vejigas de cerdo. Tras el cierre del defecto vesical con suturas barbadas y no barbadas, comprobaron con una cistometría como el volumen de la vejiga para conseguir la fuga debe ser mayor en el cierre con sutura barbada (419,7 ml) que con sutura no barbada continua (353,08 ml) o a puntos sueltos (276,2 ml).…”
