Endoscopic Ultrasound (EUS) is an advanced diagnostic procedure used to obtain highly detailed images of the digestive tract and nearby organs, including the pancreas, bile ducts, liver, and lymph nodes. Doctors often recommend EUS when conditions such as tumors, cysts, chronic pancreatitis, gallstones, or early-stage cancers are suspected but cannot be clearly identified through standard imaging tests like CT scans or MRI. EUS is also widely used to determine the stage of cancer and to guide fine-needle biopsy for accurate diagnosis.
The procedure is performed using a thin, flexible endoscope fitted with a high-frequency ultrasound probe at its tip. The scope is gently passed through the mouth into the esophagus, stomach, or small intestine. From this close position, ultrasound waves produce clear and precise images of internal organs and surrounding tissues. Patients are usually given sedation to ensure comfort during the test.
EUS is considered safe and minimally invasive, with a low risk of complications. It plays a crucial role in early detection, accurate diagnosis, and effective treatment planning, helping doctors make informed decisions and improve patient outcomes.
