Abstract
Purpose: Pancreatic duct brush cytology (PDBC) performed at ERCP has been reported to have an accuracy from 35–80%, and has been limited by false negative diagnoses and non-diagnostic cytological results (i.e. atypical or indeterminate). Such limitations may reflect a technical inability to approach or traverse pancreatic duct strictures with currently available devices and obtain adequate tissue samples. To improve apposition with the target lesion, the filiform tip of the 0.021 inch CytoMax® brush (Wilson-Cook, Winston-Salem NC) was removed. Our experience with this modified brush is reported.
