title: [Long-term follow-up of 9 islets of Langerhans autografts after resection of the pancreas].
abstract: BACKGROUND
  Preservation of physiological endocrine pancreatic function represents a major problem in pancreatectomised patients. In 40 to 100%, pancreatic resection can result in diabetes, which is often difficult to manage. Islet autotransplantation has been proposed to prevent this severe metabolic consequence.
  
  
  METHODS
  Between March 1992 and January 1997 we performed 9 human islet autotransplantations in Geneva. The patients comprised 6 males and 3 females aged 40 to 81 years (median: 51 years). The pancreatectomy was total in 3 cases, subtotal (95%) in 2 cases and partial (40-80%) in the others. Indications for resection were alcohol-induced chronic pancreatitis (6 cases) and focal benign pancreatic pathologies (3 cases). After collagenase digestion, unpurified islets were injected intraportally and embolised into the liver. Patient metabolic status was regularly tested by 24-hour serum glucose profile, measurement of glycosylated haemoglobin, oral and intravenous glucose tolerance tests and glucagon stimulation test.
  
  
  RESULTS
  Immediately after autotransplantation, one patient had persistent insulin-dependent diabetes. Among the 8 patients who were insulin-independent soon after the graft, 4 presented a progressive deterioration of endocrine pancreatic function and required insulin therapy 5, 8, 24 and 36 months after the graft. Currently, 4 patients are insulin-independent: three of them have normal glucose tolerance tests (24, and 48 months after the graft) and the last presented with glucose intolerance 22 months after the graft but still does not require exogenous insulin.
  
  
  CONCLUSIONS
  Islet autotransplantation can be considered a useful therapeutic option serving to prevent or delay the occurrence of surgically-induced diabetes. In our opinion, islet autotransplantation should be offered to any non diabetic patient needing to undergo major pancreatic resection.
