Percutaneous ultrasound-guided core needle biopsy of solid pancreatic masses: Results in 250 patients.

Background: To determine the diagnostic accuracy and complications of percutaneous sonographic (US)-guided core needle-needle biopsy in the diagnosis of solid pancreatic masses.

Methods: Cases of US-guided percutaneous core needle biopsy of solid pancreatic masses performed in our department between July 2009 and June 2015 were analyzed retrospectively. The demographic data, lesions' size and location, pathology results, accuracy, sensitivity, specificity, positive predictive value, negative predictive value, and complications of the biopsies were determined.
