case_images:  Case 1: The patient had pancreatic ductal adenocarcinoma (PDAC) and received an open radical PD with Roux-en-Y reconstruction procedure over 2 years ago (Figure 1A).  Case 2: The patient received an open radical PD with Roux-en-Y because of PDAC about a year ago and had regular chemotherapy after that (Figure 1B).  Case 3: The patient was diagnosed with chronic pancreatitis and given an open radical PD with Roux-en-Y since the pancreatic head enlargement compressed the common bile duct and pancreatic duct (Figure 1C).  Case 4: Esophagogastroduodenoscopy (EGD) and computed tomography confirmed periampullary adenocarcinoma (Figure 1D-F), and the patient received an open radical PD with Roux-en-Y procedure.
