A 35-year-old female who suffered from recurrent pancreatitis was admitted to our hospital. Her magnetic resonance cholangiopancreatography revealed ansa pancreatica. And during endoscopic retrograde cholangiopancreatography, a major duodenal papilla adenoma was identified. Hybrid endoscopic mucosal resection of this lesion was performed with pancreatic stent placement through the minor papilla to prevent recurrent pancreatitis. To our knowledge, this is the first report of a major papilla adenoma associated with ansa pancreatica. These minimally invasive endoscopic treatments solved a difficult clinical problem and avoided traumatic surgery.
