Tumor enucleation with preoperative endoscopic transpapillary stenting for pediatric insulinoma

The 13-year-old boy underwent tumor enucleation for pancreatic head insulinoma close to the pancreatic main duct after a preoperative endoscopic pancreatic stent placed by endoscopic retrograde cholangiopancreatography. The tumor was safely excised by identifying the indwelled pancreatic stent during the surgical procedure without pancreatic duct injury or postoperative complications.
