Endoscopic Ultrasound-Guided Fine Needle Aspiration has High Diagnostic Value in the Diagnosis of Solid Pancreatic Lesions.

EUS-FNA has a high diagnostic value in the evaluation of solid pancreatic lesions. Lesion size, dilation of the pancreatic duct or bile duct, negative pressure, and suction method are potential factors influencing the diagnostic ability of EUS-FNA in patients with solid pancreatic lesions. In terms of medical treatment, specific treatment methods and drug choices should be based on a comprehensive evaluation of the nature of the patient's lesions and the severity of the condition.
