The concept of operations to be 'as resective as necessary and as organ-preserving as possible' has led to the novel technique of resection of the entire duodenum, with complete preservation of the head of the pancreas, as a better alternative to the classic pancreaticoduodenectomy. This operation requires meticulous technique and precise knowledge of pancreatic and peripancreatic anatomy. Indications include benign or premalignant conditions confined to the duodenal mucosa, usually familial adenomatous polyposis. When appropriately performed, pancreas-preserving total duodenectomy leads to shorter operative time, requires less and safer anastomoses, and optimizes postoperative endoscopic surveillance. The available long-term results are encouraging.
