Pancreatic transplantation in the rat. An experimental model.

Following the induction of experimental diabetes in two groups of rats using an isograft model, a comparative study was made of two types of pancreas transplants in which several procedures were employed. The vascular anastomosis in one group were to the renal artery and vein, and in the other, to the iliac vessels. The pancreatic ducts in one subgroup were ligated, in another, they were diverted to the urinary system; in a third sub-group, they were diverted to the intestine. The results obtained for the sub-group with the transplant anastomosed to the renal vessels were the best. It is suggested that this was due to two factors: the simplicity of the technique and the short operating times. In this present work the two best methods of dealing with the exocrine secretion were diversion to the ureter and ligation of the common bile duct. The worst results were in the group with duodeno-cystostomy.
