Endoscopic Ultrasound-Guided Fine Needle Aspiration (EUS-FNA)

Endoscopic Ultrasound-Guided Fine Needle Aspiration (EUS-FNA) is a minimally invasive medical procedure used to obtain tissue samples from organs near the digestive tract, such as the pancreas, lymph nodes, or bile ducts. During the procedure, a flexible tube with an ultrasound device and a thin needle is inserted through the mouth and guided into the target area using real-time ultrasound imaging. The needle collects small tissue samples for analysis, helping doctors diagnose conditions like cancer or infections. EUS-FNA provides accurate, targeted sampling with minimal discomfort and low risk for the patient.
