The Contribution of a Collagen Patch Coated With Fibrin Glue in Sealing Upper Gastrointestinal Defects: An Experimental Study.

Abstract

We aimed to evaluate the safety and efficacy of sealing primary upper gastrointestinal (GI) perforations with a collagen patch coated with fibrin glue (Tachosil®). Thirty New Zealand rabbits were used in this study. An iatrogenic gastric perforation was created, and primary repair was performed on the control group. Tachosil®, without suturing the deficit, was used in the intervention group. Leakage was observed in 3 (20%) and 2 rabbits (13.3%) in the control and intervention group, respectively; however, the difference was not statistically significant (p=0.62). Moreover, adhesions formed in 10/15 and all rabbits in the intervention and control group, respectively (p=0.014); however, based on the Zuhlke adhesion's classification, there was no statistically significant difference between the two groups. A collagen patch coated with fibrin glue is not a replacement but can be considered a safe option for the reinforcement of suturing, preventing leakages in the upper GI tract.
