EUS: Endoscopic Ultrasound

Endoscopic Ultrasound (EUS)

     EUS (Endoscopic Ultrasound) is an advanced procedure that combines endoscopy (a flexible tube with a camera) and ultrasound to examine the digestive tract. This technology allows doctors to perform in-depth examinations and collect biopsy samples simultaneously.

Key Advantages of EUS

• Comprehensive Examination: Used to examine both the upper and lower digestive tract (e.g., esophagus, gallbladder, pancreas).
• Detailed Imaging: Provides clear, high-resolution images to assess the extent and depth of disease progression.
• Precise Access: Helps locate and visualize hard-to-reach or hidden lesions.
• Targeted Biopsy: Enables accurate needle aspiration/biopsy to collect tissue samples during the procedure.

Procedure Overview

     A flexible, small-diameter tube (endoscope) is inserted through the mouth or rectum. The device then emits high-frequency sound waves to create diagnostic images of the digestive wall and surrounding organs.

Patient Preparation

• Fasting: Do not eat for at least 8 hours before the procedure.
• Fluids: You may drink clear water up to 3 hours before the procedure.
• Companionship: It is recommended to bring a close relative or friend for support.
• Medication/Conditions: Inform the doctor or nurse about any underlying medical conditions or regular medications.
