Evaluation of a novel suture material for closure of intestinal anastomoses in canine cadavers
2012
Hansen, Lane A. | Monnet, Eric L.
Objective: To compare leakage and maximum intraluminal pressures for a novel suture material with pressures for comparable suture material when used in closure of intestinal anastomoses in canine cadavers. Sample: Healthy intestines from cadavers of dogs euthanized for reasons unrelated to the study. Procedures: 18 anastomoses were performed on intestinal sections within 72 hours after dogs were euthanized and intestinal samples collected. Anastomoses were performed with a simple continuous suture pattern. Leakage and maximum intraluminal pressures were measured and recorded for 6 control segments and 18 anastomosed sections. A barbed glycomer 631 suture (size 4–0 United States Pharmacopeia [USP]) was compared with glycomer 631 sutures (sizes 3–0 and 4–0 USP). Results for leakage and maximum intraluminal pressures were compared via an ANOVA. Results: The barbed glycomer 631 suture material leaked at a significantly higher pressure than did the comparable glycomer 631 suture materials. Maximum intraluminal pressures were not significantly different among the suture materials. Conclusions and Clinical Relevance: Barbed glycomer 631 4–0 USP suture material was as effective as glycomer 631 suture materials and may be a safe alternative for use in closure of enterectomies in dogs.
