Abstract
Six patients are described to illustrate the operative management of tubulovillous neoplasms of the duodenum. Pancreaticoduodenectomy is appropriate for associated invasive carcinoma. Transduodenal submucosal excision of tubulovillous neoplasms with resection and reconstruction of the distal bile and pancreatic ducts if necessary is a satisfactory alternative when the neoplasm has not penetrated the muscularis mucosae.
