Surgical Strategies for Tumors of the Pancreas and Duodenum

The recommended surgery for pancreatic tumors is dependent on the diagnosis. For pancreatic adenocarcinoma, duodenal, and ampullary adenocarcinoma, a Whipple pancreaticoduodenectomy with lymph node dissection is recommended. For small < 2 cm or non-imageable gastrinomas, duodenal transillumination, duodenotomy, duodenal tumor excision and adjacent lymphadenectomy is recommended. For large > 3 cm gastrinomas, a Whipple pancreaticoduodenectomy with adjacent lymph node dissection is recommended. For small 1-2 cm insulinomas, intraoperative ultrasound with enucleation is recommended. If the patient with gastrinoma, insulinoma, or multiple nonfunctional NETs occurs in the setting of MEN-1, a subtotal pancreatectomy with or without splenectomy with enucleation of pancreatic head tumors is recommended, with adjacent lymph node dissection. The detail of each procedure is described with illustrations.
