Endoscopic ultrasound is a procedure that combines endoscopy and ultrasound to create images of the digestive tract and nearby organs and tissues. It also is called EUS. During EUS, a thin, flexible tube called an endoscope is placed in the digestive tract.

Endoscopic Ultrasound (EUS) is a procedure that allows for diagnosis and staging of many cancers including lung, esophagus, stomach, pancreas, bile duct and rectum. In addition, EUS evaluates diseases of the lymph nodes of the chest, abdomen and pelvis, as well as masses in …

Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) has been generally used since 1992 for the sampling of pancreatobiliary tissues [1]. However, EUS-FNA is subject to sampling error, which can make some EUS-FNA biopsy specimens inadequate for pathological diagnosis.

2024年8月19日 · Endoscopic ultrasound (EUS) is a diagnostic test that combines endoscopy and ultrasound to obtain images and information about the digestive tract and the surrounding tissue and organs.

This animation describes Endoscopic Ultrasound-Guided Fine-Needle Aspiration (EUS-FNA), an endoscopic procedure used to obtain detailed images of the digestive tract, including the...

2024年3月22日 · This topic will review the technique, indications, contraindications, and adverse events related to EUS-guided fine needle aspiration (EUS-FNA) in the GI tract. A discussion on indications and technique for EUS-guided fine needle (core) biopsy (EUS-FNB) is …

Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is a technique which allows the study of cells obtained through aspiration in different locations near the gastrointestinal tract. EUS-FNA is used to acquire tissue from ...

2023年10月13日 · EUS-guided fine needle aspiration (FNA) can be performed at the same time as the diagnostic examination and offers a diagnostic accuracy of up to 90 percent depending upon the site of the target lesion. However, EUS-FNA is associated with several limitations.

EUS and EUS-guided FNA (EUS-FNA) have emerged as accurate and safe methods for diagnosing and staging GI and select non-GI malignancies. In addition, EUS-FNA is used to aspirate fluid from cystic lesions, pseudocysts, and fluid collections for both diagnostic and therapeutic pur-poses.

The high diagnostic accuracy of EUS-FNA and its excellent safety profile facilitated its widespread adoption in most hospitals and cancer centers. This paper aims at introducing the proper technique for EUS guided tissue sampling and highlights the related aspects of cytological and histological processing. SAmPlINg TECHNIQUES
