[Autotransplantion of Langerhans islets after total duodeno-pancreatectomy in a patient with chronic pancreatitis (author's transl)].

Total duodenopancreatectomy was performed in a 36-year-old man because of global chronic pancreatitis. Islets cells were isolated by collagenase digestion from the resected pancreas and re-implanted into the liver via the portal vein. Until the sixth postoperative day the amount of insulin required fell from 54 IU initially to 10 IU per day. Serial insulin determination demonstrated secretion by the implanted cells.
