Intraductal papillary mucinous neoplasms as tumor structures are formed in mucin-producing columnar cells of pancreas. Three types of Intraductal papillary mucinous neoplasms have been described including main duct, branch duct and mixed typed. Branch duct intraductal papillary mucinous neoplasm involves the branch duct of wirsung duct. In this review unlike the other ones with similar topics our focus is on the branch duct intraductal papillary mucinous neoplasm and especially about comparing the method for its diagnosing. There are various modalities which can be used in setting of diagnosis classification and management of branch duct intraductal papillary mucinous neoplasms,hence in our study we will assess the diagnostic yield of endoscopic ultrasound, endoscopic retrograde cholangiopancreatography and magnetic resonance cholangiopancreatography for branch duct intraductal papillary mucinous neoplasms. Endoscopic ultrasound, endoscopic retrograde cholangiopancreatography and magnetic resonance cholangiopancreatography are three precise modalities that will be discussed. Our review evaluates each of them and their role in diagnosing branch duct intraductal papillary mucinous neoplasms. Initially it is necessary to have an overview of branch duct intraductal papillary mucinous neoplasms carefully then classification of diagnostic tools, specificity and sensitivity of them are discussed separately. Finally each modality including endoscopic ultrasound, endoscopic retrograde cholangiopancreatography and magnetic resonance cholangiopancreatography have been compared together and the diagnostic yield of each modality has been explained in detail. Because of the significant role of magnetic resonance imaging and computed tomography scan, these modalities have been considered in addition to the major topic tools. At the last part the potential role of the other new technologies in managing of branch duct intraductal papillary mucinous neoplasms in the future are discussed.
