Core Tip
Core tip: This study was performed to evaluate the usefulness of cytology of the pancreatic juice obtained via the endoscopic naso-pancreatic drainage tube (ENPD-C). We retrospectively investigated 35 patients with pancreatic disease. ENPD-C was performed in 24 cases and ENPD-C plus brush cytology (ENPD-BC) in 11 cases. The sensitivity and specificity for all patients were 35% and 100%, respectively. The cytology-positive rate was 37.5% (6/16) for pancreatic cancer and 33% (1/3) for intraductal papillary mucinous cancer. Sensitivity may be further increased by adding brush cytology. We can diagnosis cancer in cases of a positive result (class V/IV) but the accuracy of ENPD-C remains unsatisfactory.
