[Autotransplantation of islands of Langerhans in dogs].

Six dogs received intraportally an autograft of isolated non purified pancreatic islets after total pancreatectomy. The isolation was made by collagenase technique, using a quarter to a half of the total pancreatic mass. The results of different transplantation technics are discussed. We conclude the necessity of: 1) a good venous distension of the pancreas, 2) the use of at least a third of the pancreatic gland to prepare the islets, 3) a tissue reinjection the closest as possible of the portal vein.
