Evaluation of two novel self-anchoring barbed sutures in a prophylactic laparoscopic gastropexy compared with intracorporeal tied knots.

Abstract

OBJECTIVE: To compare laparoscopic gastropexy using 2 self-anchoring barbed sutures to gastropexy using laparoscopically tied intracorporeal knots. STUDY DESIGN: Prospective, randomized controlled, clinical trial. ANIMALS: Dogs (n&#x2009;=&#x2009;30) weighing >16&#x2009;kg. METHODS: Dogs were randomly assigned to 1 of 3 laparoscopic gastropexy groups: group 1 (controls), intracorporeal 2-0 polydioxanone sutures (PDSII, Ethicon); group 2, barbed suture (0 Quill&#x2122; PDO; Angiotech); and group 3, barbed suture (2-0 V-Loc&#x2122; 180; Covidien). Gastropexy suturing time (GST) and total surgery time (TST) were recorded for each dog. Complications were recorded. Each dog was examined by ultrasound (1, 3, and 6 months postoperatively) to ensure persistence of the gastropexy. One dog each in group 2 and group 3 had 2nd look laparoscopy to evaluate the gastropexy. RESULTS: All gastropexies were intact at 6 months. Mean GST was significantly longer for group 1 (36&#x2009;minutes; range, 25-46&#x2009;minutes) than for groups 2 (20&#x2009;minutes; range, 16-37&#x2009;minutes) and 3 (19&#x2009;minutes; range, 15-30&#x2009;minutes; P&#x2009;<&#x2009;.05), which were not significantly different from each other. Likewise TSTs for groups 2 and 3 were significantly shorter than for group 1 (P&#x2009;<&#x2009;.05). CONCLUSION: Barbed sutures (Quill&#x2122; and V-Loc&#x2122;) allowed for effective intracorporeal laparoscopic suturing of an incisional gastropexy without tying intracorporeal knots.
