Abstract：Objective To summarize clinical features,misdiagnosed causes and treatment methods of autoimmune pancreatitis( AIP). Methods Clinical data of 3 AIP patients during September 2015 and April 2016 was retrospectively ana-lyzed. Results The 3 patients were all males,one patient had painless progressive jaundice,and the second patient had ma-ransis and diarrhoea,and the third patient had back pain and apocleisis. Pancreatic enlargement existed totally or partially, and cholangiectasis was found in exterior and interior of liver,which prompted pancreatic or bile duct occupying lesions by ico-nography examination for the 3 patients. The patients were all misdiagnosed as having pancreatic cancer in other hospitals. Their serum levels of tumor makers were normal,and immunoglobulin G4(IgG4)levels were elevated after admission in our hospital,and AIP was confirmed. One patient underwent endoscopic retrograde cholangiopancreatography of common bile duct stent implantation,and glucocorticoids treatment was given,and then stent was taken off in postoperative 3 months when he was in a stable condition. The other 2 patients received glucocorticoids treatment. The 3 patients were in stable conditions. Conclusion AIP should be suspected for doubt pancreatic cancer patients with pancreatic diffuse enlargement. Serum immu-nological test and experimental glucocorticoid therapy should be performed to help differential diagnosis in order to avoid misdi-agnosis and unnecessary operations.
