Our group is collecting data on mucinous/cystic pancreatic tumors (MCPT) to better define the ERCP features. METHODS: Data are tallied via questionnaire and/or ERCP film review, specifically in reference to 1. Appearance of the papillae, 2 Ductal filling defects, 3. Cyst filling, 4 Main pancreatic duct cut-off, 5. Main duct or side branch displacement and 6. Bile duct obstruction. RESULTS: To date, data for 102 patients have been collected with ERCP findings on 72. A cystic stricture ≥ 1.2 cm was seen on CT scan or ultrasonography in 43%. Presenting features were clinical pancreatitis 44%, steatorrhea or weight loss 40%, obstructive jaundice 18% and new onset diabetes 8%. Histologic confirmation was available in 88%.

SUMMARY: ERCP features are similar in benign and malignant mucinous duct ectasia. Serous cystadenomas mainly cause duct displacement. Mucinous cystadenocarcinomas are characterized by ductal filling defects, cyst filling, and/or main pancreatic duct cut-off. Biliary obstruction was present in benign and malignant lesions CONCLUSION: ERCP findings in mucinous and cystic pancreatic tumors are being better characterized. The goal is to tally 100 mucinous duct ectasia patients and 100 other cystic tumors. Cases may be added to the series by contacting any author.
