For neoplasms in the third and fourth parts of the duodenum, a duodenectomy that preserves the pancreas may provide feasible tumor clearance while avoiding the additional dissection and pancreaticoduodenectomy. We herein describe the case of a 40-year-old male patient with an adenoma in the third part of the duodenum. The patient underwent a partial duodenectomy of the distal region, preserving the pancreas and Vater's papilla. The residual duodenum and jejunum were successfully reconstructed by an end-to-side anastomosis. We also present a review of the English literature regarding pancreas-preserving partial duodenectomy of the distal region.
