Clinical paradigms revisited

To the Editor: I was surprised by Wong’s letter on the role of history-taking and examination in the diagnostic process.1 I would suggest that Wong, as a surgical registrar, receives the majority of his abdominal pain referrals from the medical staff of the emergency department. Although he advocates the liberal use of abdominal computed tomography (CT) scanning, I believe he ignores the fact that another medical practitioner has already taken a history and performed an examination that has suggested a surgical cause of pain for which a surgical opinion is then requested. Wong would thus remain unaware of other cases in which patients present with abdominal pain but the case is ruled non-surgical on the basis of history, examination and limited investigation not involving abdominal CT scanning.
