Pancreas-sparing duodenectomy: indications, surgical technique, and results.

BACKGROUND: Pancreatoduodenectomy, originally performed for malignancy of the pancreas and duodenum, is also commonly used for potentially malignant lesions. Because a normal pancreas should be spared, we investigated the concept of duodenectomy alone with the pancreas intact for diseases such as familial adenomatous polyposis syndrome.
METHODS: Five patients underwent pancreas-sparing duodenectomy for nonmalignant lesions performed by means of meticulous detachment of the duodenum from the pancreas, transecting the bile and pancreatic ducts outside the duodenum. Reconstruction was accomplished by advancing the jejunum to anastomose end-to-end with the juxtapyloric duodenal cuff, implanting the bile and pancreatic ducts in a location corresponding to the native papilla. The hospital course, complications, and long-term follow-up status of all patients are reviewed in detail.
RESULTS: No deaths occurred in this series. Delayed gastric emptying was seen in one patient and transient pancreatic fistula in another. Long-term endoscopic follow-up showed no stenosis of the ductal anastomoses. Endoscopic surveillance, including endoscopic retrograde cholangiopancreatography, was not hampered by this technique of reconstruction.
CONCLUSIONS: Pancreas-sparing duodenectomy is a practical operation for nonmalignant duodenal lesions where the pancreas is not involved by the disease process.
