Pancreas preserving duodenectomy for duodenal polyposis in familial adenomatous polyposis.

Duodenal polyposis is common in familial adenomatous polyposis with a significant associated lifetime risk of cancer. Screening and regular surveillance is recommended, guided by the Spigelman stage. Pancreas preserving duodenectomy (PPD) is the preferred operation in patients needing removal of the whole duodenum. This presentation demonstrates the technique of PPD with particular emphasis on the resection and ampullary reconstruction. Initial early feeding tube placement through the cystic duct stump into the duodenum enables identification of the papilla and pancreatic duct as well as subsequent dissection. Separate trans-anastomotic pancreatic and biliary stents facilitate creation and patency of the pancreato-biliary anastomosis. The operation has similar outcomes compared to pancreaticoduodenectomy, however, the anatomical reconstruction allows for postoperative surveillance.
