Endoscopic Ultrasound (EUS)
What is Endoscopic Ultrasound (EUS)?
EUS is a procedure that combines the use of an endoscope (a thin, flexible tube with a light and camera) inserted into the gastrointestinal tract with an ultrasound device to capture detailed images. This combination allows for comprehensive imaging of the digestive tract and surrounding tissues and organs.
Importance of EUS:
This procedure is used to obtain detailed images of:
- Stomach and parts of the small intestine
- Rectum and parts of the large intestine
- Lungs
- Lymph nodes in the middle of the chest
- Liver
- Gallbladder
- Bile ducts
- Pancreas
Additionally, a thin needle can be used during the procedure to access other organs, such as:
- Accessing lymph nodes through the esophageal wall
- Accessing the pancreas through the stomach wall
A thin needle in the endoscope can also be used to take samples of tissues or fluids for laboratory examination.
Uses of EUS:
- Assessing tissue damage caused by inflammation or disease.
- Determining the extent of cancer spread in tissues and lymph nodes.
- Aspiring fluids from cysts.
- Collecting samples of tissues or fluids for laboratory analysis.
- Delivering and injecting certain medications into specific areas, such as malignant tumors.
Preparation for EUS:
- asting for at least 6 hours before the procedure.
- f the procedure involves the rectal area, bowel cleansing with laxatives and a liquid diet may be required.
- Inform the doctor of any medications being taken for chronic or other health conditions to review their use before the procedure.
- lean meats
- eggs.
- Raw vegetables.
The EUS procedure typically takes less than an hour.
Risks of EUS:
EUS is generally safe when performed by a skilled specialist in a well-equipped and prepared facility. However, it may occasionally carry some risks, such as:
- Bleeding
- Infection
- Perforation of the intestine
- Pancreatitis.
