Diagnosing SBO in the ED

BMJ Blog - 23 May, 16 - By rlloyd
"Diagnosing small bowel obstruction (SBO) is bread-and-butter work for the emergency physician. It accounts for 2% of patients presenting to the ED with abdominal pain, and 20% of all surgical admissions. In the developing world the majority of SBO patients have had previous intra-abdominal surgeries causing adhesions… But I won’t delve into aetiology, let’s talk diagnostics...
Ultrasonography comfortably outperformed plain radiography in detecting SBO. A sensitivity of 93.9% and specificity of 81.4% left AXR trailing behind with a sensitivity of 46% and specificity of 67%. Dilated loops on ultrasound proved to be far more sensitive than reduced peristalsis – probably because reduced peristalsis is generally considered to be a late finding in SBO, often seen with strangulation."
