Safety and Efficacy of Ultrasound-Guided Percutaneous Core Needle Biopsy of Pancreatic and Peripancreatic Lesions Adjacent to Critical Vessels.

Purpose: To evaluate the safety and efficacy of ultrasound-guided percutaneous core needle biopsy (USPCB) of pancreatic and peripancreatic lesions adjacent to critical vessels.

Materials And Methods: Data were collected retrospectively from 162 patients who underwent USPCB of the pancreas ( = 98), the peripancreatic area adjacent to the portal vein, the paraaortic area adjacent to pancreatic uncinate ( = 34), and lesions on the third duodenal portion ( = 30) during a 10-year period. An automated biopsy gun with an 18-gauge needle was used for biopsies under US guidance.
