[Islands of Langerhans autotransplantation after pancreatic resection for benign pathology].
One way to prevent the occurrence of insulin-dependent diabetes after major pancreatic resection is to perform islet of Langerhans autotransplantation. Thus far, we have performed nine autotransplantations. The last three autotransplantations were performed in patients with benign tumoral pathology (one corporeal mucinous cyst, one isthmic insulinoma and one corporeal cystadenoma). In these three cases, we performed a distal 40%, 75% and 80% pancreatectomy respectively, since enucleation was not indicated or not feasible. After resection and removal of the tumoral lesion, pancreatic segments were injected intraductally with collagenase and digested according to a modified semi-automated Ricordi's technique. We obtained 105,000, 415,000 and 144,300 non-purified islets which were then embolized into the liver by intraportal injection during the same operative procedure. After surgery, all patients were insulin-independent. There was no morbidity or mortality. In a patient who presented acute pancreatitis of the residual pancreas five months after transplantation, insulin therapy was introduced. More than one year after the graft, the two other patients remain insulin-independent. In conclusion, we propose islet autotransplantation after pancreatic resection for benign focal pathology, to prevent or delay the occurrence of insulin-dependent diabetes.
