Endoscopic Ultrasound (EUS) provides detailed images of your digestive tract, providing more information than any other imaging method. The most sensitive examination of pancreas, liver, gallbladder and biliary tract disorders can be done with EUS. Endoscopic ultrasound is also used to take biopsies from the masses observed in these organs. The EUS procedure allows the correct diagnosis to be made in cases where it is not sure with other imaging methods.
What is Endoscopic Ultrasound (EUS)?
Endoscopic Ultrasound (EUS) is a type of endoscopic examination. It involves the introduction of a thin tube into the mouth and stomach and the first part of the small intestine. At the end of the tube is a small ultrasound probe that emits sound waves. These sound waves are reflected from surrounding structures such as the stomach, small intestine, pancreas, bile ducts, and liver. These sound waves are then recaptured by the probe and converted into black and white images that will then be interpreted by your doctor. The procedure is performed by putting you to sleep under sedoanalgesia and usually takes 20 to 45 minutes.
Why is Endoscopic Ultrasound Performed?
EUS provides detailed images of your digestive system, giving your doctor more information than any other imaging test. Your doctor may use EUS to diagnose certain conditions that may be causing abdominal pain or abnormal weight loss.
EUS is also used to assess known abnormalities, including lumps or lesions detected in a previous endoscopy or seen on X-ray tests such as a computed tomography (CT) scan. EUS can be used to diagnose diseases of the pancreas, bile duct and gallbladder when other tests are inconclusive or contradictory.
How is Endoscopic Ultrasound Performed?
In our gastroenterology unit, like all other procedures, endoscopic ultrasound is performed under sedoanalgesia and put to sleep. The procedure begins by laying the patient on your left side. After the patient is put to sleep, your gastroenterologist will advance the ultrasound endoscope through your mouth, esophagus, and stomach into the duodenum. The device used does not prevent you from breathing during the procedure. The process usually takes less than 60 minutes. Since the procedure is performed by putting them to sleep under sedation, patients do not remember the procedure after the procedure.
Before the Endoscopic Ultrasound procedure, the patient should be hungry and thirsty for the last 8 hours.
Before starting the procedure, the patient wears the surgical garment in the rest section. Then, the patient’s vascular access is opened and his throat is anesthetized
Don’t be put to sleep
The patient, who is evaluated by the anesthesia department before the procedure, is put to sleep with sedoanesthesia.
The stomach of the anesthetized patient is descended and examined in the necessary areas under the guidance of endoscopic ultrasound.
A piece is taken from the necessary tissues or detected masses with an EUS needle. The part taken is checked by the pathology department during the procedure.
Submission of the Report
After the procedure, the patient is taken back to the rest room. After about 1 hour, after the effect of the narcosis wears off, the procedure report is delivered to the patient and the patient is discharged. If biopsies are taken in the procedure, it may take 7-10 days for their laboratory results to appear.
In Which Disorders Is Endoscopic Ultrasound EUS Used?
In which ailments is ultrasound EUS used?
- It is used to empty the bile ducts blocked due to cancer into the stomach or small intestine with EUS or to insert a stent
- Diagnosis of esophageal cancer, stomach cancer, rectal cancer, biliary tract cancer, pancreatic cancer, biopsy, detection of cancer at an early stage, investigation of recurrence findings in postoperative follow-up, examination of cancer involvement in lymph nodes and vessels in neighboring organs around the rectum (prostate, bladder, vagina) and determination of the degree of tumor (T1, T2, T3, T4)
- Barrett’s esophagus
- Bile duct stones
- Neuroendocrine tumors,
- Pancreatitis and pancreatic cysts
- Anal fistula
- Gas and fecal incontinence
- Biopsy of masses in the liver
Why is EUS Used in Cancer Patients?
EUS helps your doctor determine the extent to which certain cancers in the digestive and respiratory system have spread. EUS allows your doctor to accurately assess the depth of the cancer and whether it has spread to neighboring lymph nodes or nearby vital structures, such as large blood vessels. In some patients, EUS may be used to obtain a needle biopsy of a lump or lesion to help your doctor determine the appropriate treatment.
How to Prepare Before EUS Procedure?
For his EUS, nothing should be consumed, usually 6 hours before the examination. Your doctor will tell you when to stop eating and drinking, and if you have medications that you need to take regularly, whether you can use them before the procedure.
For EUS of the rectum or colon, your doctor will tell you to either consume a colon cleansing solution or follow a clear liquid diet combined with laxatives or enemas before the exam. It is necessary to follow the doctor’s instructions carefully, otherwise the procedure may need to be rearranged.
