title: Local excision of periampullary villous tumours of the duodenum.
abstract: OBJECTIVE
  Our goal was to describe our technical approach to transduodenal submucosal resection of periampullary villous tumours of the duodenum.
  
  
  METHODS
  We address technical tips to aid in exposure and reconstruction of pancreaticobiliary continuity with special reference to the indications for adding biliary sphincteroplasty, pancreatic septectomy, and local resection of neoplasms extending past the immediate ampullary mucosa into the bile and/or pancreatic ducts.
  
  
  CONCLUSIONS
  This approach has proven safe, easy and without significant morbidity.
