Tumours that fall under this group includes four main types of tumours 1,4
- pancreatic head / uncinate process tumours: includes pancreatic ductal adenocarcinoma involving head and uncinate process of the pancreas
- lower common bile duct tumours: includes types of cholangiocarcinoma involving the intra-pancreatic distal bile duct
- ampullary tumours: those originating from the ampulla of Vater itself
- periampullary duodenal carcinoma
Although patients with periampullary tumors have similar symptoms at presentation, they exhibit different clinical outcomes according to the origin of these tumours.
Their origins are difficult and often impossible to discern based on clinical settings and on preoperative imaging. The presence of a bulging papilla sign may suggest towards the diagnosis.
