ABSTRACT
We report three cases of mucinous ductal ectasia which was suggested by the abdominal computed tomography and finally diagnosed by the duodenoscopy with pancreatosocpy. Duodenoscopic findings of ampulla Vater demonstrated patulous papillary orifice and extrusion of viscid mucus. Pancreatoscopic examination was performed in all three cases and characteristic findings such as papillary or villous mucosal projections coated with whitish gelatinous mucus were noted. In patients of mucinous ductal ectasia with an equivocal radiologic appearance, pancreatoscopic examination may give valuable information in the differential diagnosis of amorphous filling defects in the main pancreatic duct and may provide some information in determining the extent of pathology and the resection margin.
