What is the role of survey radiographs in chronic diarrhea assessment?

• A. Identify obstruction, mass effect, or surgical disease
• B. Assess wall thickness directly
• C. Measure mucosal thickness
• D. Detect Giardia infection

Answer: (A)

Survey radiographs mainly help you spot gross structural problems that could be causing or mimicking chronic diarrhea, such as obstruction, mass effect, or prior surgical changes. They provide a quick look to detect signs like dilated intestinal loops or air-fluid levels that point to obstruction, which would require urgent management. Radiographs, however, do not give direct information about wall or mucosal thickness; assessing those requires other imaging modalities like ultrasound or endoscopy. Detecting Giardia infection is not within the capability of radiographs, as Giardia is diagnosed via stool tests or molecular methods. So the best use of survey radiographs in chronic diarrhea assessment is to identify obstruction, mass effect, or surgical disease, guiding further diagnostics and treatment.
