Gallbladder ultrasonography should be considered if the patient has recurrent dyspepsia or characteristic postprandial pain.

Abdominal computed tomography (CT) scanning is appropriate to screen for tumors, obstruction, and pancreatic disease if these are diagnostic possibilities.

CT and magnetic resonance (MR) enterography or wireless capsule endoscopy are employed if red flags exist to suggest enteritis (small bowel inflammation) or a tumor.

Colonoscopy is appropriate if alarm symptoms are present and in patients who otherwise qualify for screening colonoscopy.
