Heterotopic autotransplantation of the distal pancreas segment after total pancreatectomy for cancer of the head of the pancreas.

Autotransplantation of the distal pancreas segment with pancreaticojejunostomy was performed in four patients with cancer of the head of the pancreas to preserve endocrine pancreatic function after extended total pancreatectomy. All patients had tumor involvement of both the celiac axis and the portal vein. The pancreatic graft was determined to be cancer-free by frozen section histologic and pancreatic juice cytologic examinations. The distal pancreas segment was autotransplanted to the iliac vessels heterotopically and placed in the extraperitoneal pocket to avoid untoward effects of any local recurrence or pancreatic leakage. This procedure, in the form of reconstruction, might be called modified subtotal pancreatoduodenectomy. Postoperatively, all patients remained normoglycemic without exogenous insulin administration, and their quality of life was considered satisfactory.
