title: Subtotal pancreatectomy for chronic pancreatitis.
abstract: Chronic pancreatitis results when pancreatic structure or function is irreversibly damaged by repeated or ongoing inflammation, regardless of the underlying etiology. Most patients present with medically intractable pain and radiological evidence of diffuse gland involvement. Surgical therapy is directed mainly toward palliation of symptoms, and cure is unusual except when the inflammatory process is limited to a specific segment of the pancreas. Surgical strategy should be individualized on the basis of alterations in pancreatic morphology and duct anatomy. In properly selected patients, duct drainage procedures effectively relieve pain and preserve pancreatic function with low perioperative morbidity and mortality. Extensive distal pancreatectomy is effective in relieving pain, but it can be technically challenging and in general should be limited to patients with small-duct disease because of severe metabolic consequences. Intraportal islet cell autotransplantation or segmental pancreatic autotransplantation may ameliorate the long-term effects of insulin-dependent diabetes, but it will have limited applicability until methods for optimizing and purifying islets are developed and the optimal route and site of islet cell implantation have been identified.
