Yield of endoscopic ultrasound-guided fine needle aspiration and endoscopic retrograde cholangiopancreatography for solid pancreatic neoplasms.
2016
AbstractObjective: Both endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) and endoscopic retrograde cholangiopancreatography (ERCP) cytology may provide tissue diagnoses in solid pancreatic neoplasms. However, there are scant data comparing these two methods. This study aims at retrospectively comparing EUS-FNA and ERCP tissue sampling and ability of cytopathological diagnosis in solid pancreatic neoplasms and to determine usefulness and adverse events of combining both procedures. Material and methods: Two hundred and thirty four patients suspected to have solid pancreatic mass on abdominal ultrasound and/or computed tomography (CT) were enrolled. EUS-FNA (group A), ERCP cytology (group B) and combined procedures (Group C) performed in 105, 91 and 38 cases, respectively. Results: Sensitivity, specificity and accuracy were 98.9%, 93.3% and 98.1% for group A, and 72.1%, 60% and 71.4% for group B. Those for group C were all 100%. Sensitivity for malignancy in the pancreas head was 100% for group...
