Bowel Obstruction Diagnosis
Exam and imaging
Diagnosis combines clinical findings with imaging. Contrast-enhanced CT is commonly used; plain films may be an early step. Labs support assessment of dehydration, infection, or ischemia—but no single test guarantees bowel viability.

Figure summary
This educational figure shows: Diagnosis · imaging.
Key points
Physical exam
Distension, tenderness, bowel sounds, prior scars, and hernia orifices—including groin and umbilicus.
CT and other imaging
CT shows level, cause, closed loop, tumor, hernia, and ischemia clues. Water-soluble contrast follow-through may help selected adhesive cases.
Laboratory support
Electrolytes, lactate, white count—support suspicion but do not replace clinical monitoring.
- Key note inside
Why serial reassessment?
An initially ‘stable’ film can progress—pain, vitals, and exam trend matter.
