Gastroscopy (gastroscopy): The examination itself usually takes 5-10 minutes, but of course it depends on what lesions your doctor finds and what kind of therapeutic intervention is needed. Important: at our centres, gastroscopy can be performed under general anaesthesia, eliminating any discomfort and possible pain.
Colonoscopy (colonoscopy): the examination usually takes between 15 and 40 minutes, depending on what your doctor finds and what interventions are needed. International studies have shown that a thorough examination requires a minimum of 6-8 minutes of pull-out time. This is the time it takes for the doctor to pull out the endoscope that has been inserted along the entire length of the colon. This is when the mucosa is thoroughly examined and most therapeutic procedures (e.g. removal of polyps, elimination of bleeding sources, etc.) are performed.
Important: at our centres, colonoscopies can be performed under general anaesthesia, eliminating discomfort and possible pain.
Abdominal ultrasound scan: usually 10-25 minutes, but of course the time taken depends largely on the type of lesions found.
Abdominal ultrasound-guided sampling: the length of the study depends on the type of intervention. While an ultrasound-guided abdominal fluid sampling may take a few minutes, for example, the removal of a pancreatic cyst may take longer.
Abdominal CT scan: you may need to take a contrast agent before the test. This must be swallowed and may take 1-3 hours. The CT scan takes a few minutes.
Urea breath test for Helicobacter pylori: the whole test can take half an hour to an hour and a half, depending on the type of test method.
