INTRODUCTION: A spectrum of pancreatic neoplasms can exhibit a cystic component or excess mucus production. The Midwest Pancreaticobiliary Group has collected a series of mucinous/cystic pancreatic tumors (MCPT) to better define their ERCP characteristics. METHODS: In this multicenter series, data are recorded on standardized questionairres and added to a central database. Patients with the following MCPT s were included: intraductal papillary mucinous tumor/mucinous duct ectasia (IPMT), serous cystadenoma (serous cyst), mucinous cystadenocarcinoma (M cyst CA) and mucinous cystadenoma (M. cystaden). RESULTS: 206 cases have been collected with ERCP findings on 171. Presenting features were clinical pancreatitis 32%, steatorrhea or weight loss 43%, cholestasis or obstructive jaundice 22%, and new onset diabetes mellitus 6%. Histolgical confirmation was available in 79% of cases. See table. SUMMARY: ERCP features are similar in benign and malignant IPMT. Serous cyst adenomas mainly cause duct displacement. Mucinous cystadenocarcinomas are characterized by ductal filling defects and mucus at the papilla in addition to cyst filling and/or duct cutoff. Biliary obstruction was present mainly in malignant lesions. CONCLUSIONS: The ERCP features of mucinous and cystic pancreatic tumors are being better characterized. However, benign and malignant lesions cannot reliably be differentiated on ERCP findings alone and aggressive tissue sampling is indicated. **And Members of the Midwest Pancreatobiliary Group |
