Abstract    Choledocho-pancreatico-duodenal junction is the junction region of bile duct，pancreatic duct and duodenum. The iatrogenic injury in choledocho-pancreatico-duodenal junction is the most common complication due to its special anatomy and pathophysiology characteristics. As the higher morbidity of hepatolithiasis，more adoption of HBP surgeries and the popularization of new technologies such as EST, ERCP and choledochoscopy，iatrogenic injury in choledocho-pancreatico-duodenal junction becomes more common. Injury in choledocho-pancreatico-duodenal junction is usually hard to be diagnosed during the operation，which could result in serious complications，even death. So, timely diagnosis and treatment play a significant role in the recovery and prognosis of patients.
