Endoscopic retrograde pancreatography (ERP) is recommended to detect injury of the main pancreatic duct (MPD). We report a case in which ERP was unable to detect penetrating injury of the MPD. A 75-year-old woman stabbed herself in the abdomen. Abdominal CT revealed pancreatic head injury, but ERP demonstrated no injury of the MPD. We performed simple closure of the stomach and peri-pancreatic drainage. Postoperative biliary and pancreatic fistulae were suspected. Therefore, second ERP was carried out, which confirmed injury of the MPD and the common bile duct. After the endoscopic pancreatic stent was inserted, choledochojejunostomy was performed. False-negatives may occur on ERP when assessing penetrating trauma of the MPD. In addition, endoscopic pancreatic stents are useful even for MPD penetrating trauma of the pancreatic head.
