| [ Summary ] | We reviewed endoscopic findings of autoimmune pancreatitis (AIP). Swelling of the main duodenal papilla is characteristic findings with AIP. Endoscopic retrograde cholangiopancreatography (ERCP) shows narrowing of the main pancreatic duct characteristic to AIP. The narrowing of the pancreatic duct is defined as being : "unlike the obstruction or stenosis, the narrowing extends to certain degree and the duct is narrower than normal, with some irregularities". In a typical case the narrowing extends more than one third of the entire pancreatic duct. Even when the narrowing is localized to less than one third of the entire duct, in most cases, no significant dilatation is observed above the narrowed area upstream of the main pancreatic duct. If the narrowing is localized, it is necessary to consider differentiating the disease from pancreatic cancer. Typical endoscopic ultrasonography (EUS) findings of AIP are relatively diffuse homogeneous hypoechoic pattern and linear or reticular hypoechoic inclusions. | |
