Why is this test requested?
Endoscopic ultrasound provides high-resolution imaging of the pancreas, bile ducts, gastrointestinal wall and nearby structures. The value of the test is not simply in performing it, but in answering the right clinical question. Results are interpreted alongside symptoms, previous tests and the treatment decision that follows.
Symptoms or prior tests suggesting this investigation may clarify the diagnosis
A need to stage, characterise or exclude a clinically important condition
A result that may change management
Diagnostic EUS is not a routine test for everyone. Its ability to answer the patient’s defined clinical question is considered first, and it is scheduled when the result can change treatment or follow-up.
How should you prepare?
Preparation depends on the test, your health and medicines. Follow the written instructions from your treating unit.
Previous imaging, endoscopy and pathology often improve interpretation and prevent unnecessary repeat testing.
What happens during the test?
The exact technique and monitoring depend on the investigation. Your team should explain what happens before the test begins.
How are results interpreted?
Ask when the formal report will be available, whether pathology is pending, and what result would trigger another test or treatment.
After Diagnostic EUS, Görüntüleme bulguları aynı gün açıklanabilir; örnekleme yapılmışsa sitoloji/patoloji sonucu daha sonra değerlendirilir. The result is compared with prior evidence and the report should state whether the next step is observation, endoscopy, additional imaging, tissue sampling or treatment.
