title: A successful model of small bowel autotransplantation in the dog.
abstract: Experimental small bowel transplantation has continued to be a complex procedure with high mortality. We investigated the technical aspects of small bowel transplantation in an effort to define a procedure that would result in an improved survival rate. Three methods of graft harvesting were examined in a model of canine small bowel autotransplantation. Harvesting the graft by first flushing with room-temperature lactated Ringer's followed by iced lactated Ringer's resulted in the best preservation and subsequently the best survival rate (71%). Flushing with iced lactated Ringer's alone resulted in survival rates of 22 and 50% in two additional groups. We also investigated two methods of graft reanastomosis. Although either venous drainage regimen appears to be suitable, graft venous reanastomosis to the host portal vein resulted in a slightly higher postoperative weight than reanastomosis to the host inferior vena cava. A model of small bowel transplantation with a high long-term survival rate has been developed. This model can now be applied to studies of the various physiological aspects of small bowel transplantation.
