OBJECTIVE To evaluate the effect of a bovine albumin–derivatized glutaraldehyde (BA-DG) biopolymer sealant on leakage pressures of intestinal anastomoses in jejunal tissue collected from fresh canine cadavers and to evaluate changes in circumference and cross-sectional area of the anastomotic site resulting from sealant application.

SAMPLE 24 jejunal anastomoses from 4 fresh canine cadavers.

PROCEDURES Jejunal tissue specimens were collected, and adjacent segment anastomoses were created within 12 hours after euthanasia of each dog. The tissue constructs were randomly assigned to 1 of 2 groups in which sealant was or was not applied. The outer circumference of all anastomoses in the sealant group was measured before and after application of the sealant; the cross-sectional area at the anastomotic site was then calculated at each time point. Tissue constructs were pressure tested, and leakage pressure and site were recorded. All testing was completed within 24 hours after tissue collection.

RESULTS Compared with preapplication findings, there were no significant changes in outer circumference or cross-sectional area at the anastomotic site after sealant application. Leakage pressures in the sealant group were significantly higher than those in the no-sealant group.

CONCLUSIONS AND CLINICAL RELEVANCE The use of surgical sealant on fresh canine cadaver jejunal anastomoses resulted in significantly higher leakage pressure at the anastomotic site; no immediate tissue deformation of the outer circumference or cross-sectional area occurred after sealant application. Future in vivo investigations are warranted to evaluate the effects of this sealant and potential benefits for clinical patients undergoing enterectomy.
