[Experimental liver transplantation in pigs. Surgical technique and complications].
Only recently, in our laboratory of experimental surgery, we started with a protocol for orthotopic liver transplantation (OLT) in a pig model. This was felt as mandatory for experimental purposes as well as for future clinical applications at our center. We report herein our own experience with 41 OLTx. Intraoperative "lethal" complications occurred in up to 32% (14/41) whereas postoperative complications occurred in the remainders at different intervals of time with a maximum survival of 30 days. No attention was paid to prevent rejection-infection episodes. The main cause of death was the primary non-function (PNF) or dis-function (PDF) manifested either intra or postoperatively in 16 out the 41 OLTx (39%). Intraoperative technical errors accounted for up to 9% (4/41 OLTx). Acute hemorrhage gastritis and gastric perforations occurred postoperatively in 6 animals (14%) and represent one of the peculiar aspects of OLT in pig model.
