A 75 y/o man arrives in ED from a nursing.
He complains abdominal pain.
No fever, no jaundice, abdomen presents distended.
Inspection shows a midline old scar,
there is diffuse rigidity,
increased bowel sounds and vomit on the sheets.
Can history and clinical examination contribute to diagnosis of bowel obstruction?
Conclusion
Medical history and physical examination are a good method in evaluation of a patient with a suspected bowel obstruction. Age > 50 years, distended abdomen, increased bowel sounds, vomit, history of costipation, previous abdominal surgery alone can increase the probability of bowel obstruction. The combination of three of this has a very high LR+ from 19 to infinity! Although in some case clinical examination could be diagnostic of bowel obstruction without any other investigation, the practice of plain radiography is still very diffused….what about it?
