Obligatory medical device diagnostics.
- Gastroscopy (gastroscopy) – if upper gastrointestinal bleeding (OGIB) is suspected.
- Colonoscopy (colonoscopy) including proctoscopy (rectoscopy; examination of the anal canal and the lower rectum/ rectum) – if lower gastrointestinal bleeding (UGIB) is suspected.
Optional medical device diagnostics – depending on the results of the history, physical examination, laboratory diagnostics and obligatory medical device diagnostics – for differential diagnostic clarification.
- Abdominal ultrasonography (ultrasound examination of the abdominal organs) – for basic diagnostics.
- X-ray of the abdomen, if necessary barium enema.
- Computed tomography (CT) of the abdomen (abdominal CT) or thorax/chest (chest CT) – for staging in neoplasms.
- Magnetic resonance imaging of the abdomen (abdominal MRI) or /thorax / chest (thoracic MRI) – for staging in neoplasms.
- Video colonoscopy by capsule (VCE) or a CT(computed tomography) colonography (CTC) – for colonoscopy refusal* .
Further notes
- Video colonoscopy by capsule (VCE) or CT (computed tomography) colonography (CTC) provided a respectable result in a study of colonoscopy refusers: 80% in the VCE group and 46.6% of the CTC group showed a positive result, including 12 potentially neoplastic lesions and four non-neoplastic sources of bleeding.[1].
