Pancreas-Sparing Total Duodenectomy

Pancreas-sparing total duodenectomy (PSTD), which allows preservation of the pancreas in its entirety is a promising procedure for benign or premalignant lesions at duodenum without invading the pancreas. We report two cases of tubular adenoma of Ampulla of Vater and a GIST of duodenum, which were resected by PSTD. The proximal duodenum was transected at 2 cm distal of pylorus and the distal end was cut in the distal portion of the Treitz ligament. The proximal jejunal limb was used for biliary-pancreatic duct systems reconstruction with end-to-side anastomosis and distal jejunum was anastomosed to duodenal bulb with an end-to-side anastomosis. Although a pancreatic fistula occurred in one patient, it was improved by conservative management. PSTD is a challenging surgical technique and requires excellent knowledge of anatomy. If performed for appropriate indications, PSTD is a useful alternative to formal pancreatoduodenecotmy and can be done safely with gastrointestinal function maintained.
