Objective: To compare the load to failure of incisional gastropexy performed with standard glycomer 631 (G) and with knotless glycomer 631 (GV) in ex vivo model of gastropexy.
Study design: Cadaveric study.
Sample population: Cadaveric canine stomach and body wall (n = 24).
Methods: Specimens were divided into 4 groups based on suture type (G, GV) and size (3 metric, 2 metric). An incisional gastropexy was performed on all samples, and load to failure evaluated.
Results: Gastropexy with GV had significantly higher load to failure than gastropexy performed with G (P = .0006). Suture size had no significant effect on maximum load to failure (P = .36). The interaction between size of the suture and suture materials had a significant effect on the load to failure of the gastropexy (P = .0474). Knotless glycomer 631, 3 metric had significantly greater load to failure than G 3 metric (P = .0016) and G 2 metric (P = .0107).
Conclusion: A knotless suture appears to have comparable, if not greater load to failure than a standard suture of similar composition when used in canine incisional gastropexy in an acute ex vivo model.
