Endoscopic ultrasound (eus) and fine needle aspiration and biopsy (fna-fnb)
Endoscopic ultrasound (EUS) is performed using a special endoscope equipped with an ultrasound head. EUS can help in examining lesions of the pancreas, liver, bile ducts, stomach, esophagus, mediastinum, rectum, staging of malignancies, lymph node examination, and other benign lesions of the digestive system. Fine needle aspiration and biopsy (FNA - FNB) is performed if cytological material is needed, which is then examined under a microscope.
The EUS is generally a safe test. It is done under conscious sedation, meaning the patient is asleep. The patient goes home the same day of the examination.
To prepare for the exam, follow the instructions given to you. For the EUS of the upper digestive tract, which is much more frequent than the EUS of the rectum (the final part of the colon), a similar to upper endoscopy preparation is required.
Please tell your doctor if you are taking medicines for platelets or blood clotting (aspirin, Plavix, Sintrom, Pradaxa, Xarelto, and so on), for diabetes, iron or for hypertension.
