Allotransplantation of neonatal pancreas-microfragments in man.

We report of an allotransplantation of neonatal pancreatic tissue. The donor was a three-week-old girl with nesidioblastosis, in which a subtotal pancreas resection had to be performed. The pancreas microfragments were injected transcapsularly into the spleen of a patient with juvenile diabetes. During the postoperative course only a short-termed improvement of the diabetic condition was seen.
