[Abdominal multi-organ transplantation in dogs].
Abdominal multi-organ transplantation including the liver, gallbladder, spleen, pancreas, kidneys, adrenal glands and gastrointestinal tract was attempted in 8 dogs. Each experiment was discontinued when the recipient deteriorated. Immersion hypothermia was introduced in both the donor and recipient until the esophageal temperature reached 27-30 degrees C. Whole abdominal organs of the donor were removed in an en-bloc fashion at 20 degrees C of the graft temperature after additional cooling by ice slush scattering into the abdominal cavity. Transplantation was carried out orthotopically in the following sequence: (1) the proximal aorta, (2) suprahepatic vena cava, (3) distal aorta, (4) infrahepatic vena cava. The alimentary tract was reconstructed by gastro-gastrostomy and colo-colostomy. The ureters were implanted in the bladder. Cold ischemic time of the graft was about 40 minutes. Heparin was not used throughout the procedure. Five out of eight dogs were alive for more than 24 hours and two of them survived for 60 hours with good recovery. No immunosuppressant was given. Though the result in the present study was far from satisfaction, the experiment may provide a possibility of a new experimental model for transplantation, especially regarding pathophysiology and interrelationship of the transplanted complex organs.
