In small bowel obstruction the distention is mild to massive depending on the site of obstruction (minimal or absent in proximal & mild to massive in distal) and is usually central and not generalized.\nFailure to pass meconium in the first 24 hrs is a feature of obstruction as in Hirschprung's disease.\nRefusal to feed is a common but nonspecific symptom.\nThe most common symptom suggestive of small bowel obstruction is bilious vomiting.", 'role': 'assistant'}]
