Background:
The purpose of this study is to examine the possibility of a long-term preservation of the ischemically damaged intestine by the cavitary two-layer method (TLM) in canine small intestinal transplantation.
Methods:
The grafts were allotransplanted without preservation immediately (group 1) or after 30 minutes of warm ischemia (group 2). The ischemically damaged grafts were also allotransplanted after cold preservation for 24 hours in University of Wisconsin (UW) solution (group 3) or the cavitary TLM (group 4). Seven-day survivals, tissue adenosine triphosphate (ATP) concentrations, absorption tests, and histopathology were examined.
Results:
seven-day survivals in groups 1, 2, 3, and 4 were 8 of 8, 6 of 8, 0 of 8, and 6 of 8, respectively. In group 4, significant recovery of ATP tissue level was seen after preservation compared with group 3, and absorption function and regeneration of the graft mucosa recovered at day 14.
Conclusions:
Ischemically damaged canine small intestine could be preserved for 24 hours by the cavitary TLM.
