How accurate is clinical diagnosis at identifying patients with cholecystitis?

Three Part Question

In [patients with right upper quadrant pain] does [clinical examination] accurately exclude [diagnosis of cholecystitis]?

Clinical Scenario

A patient presents to the accident and emergency department with acute onset of right upper quadrant pain. They have some associated clinical findings such as a positive murphy’s sign and you wonder if this is enough to evidence to make a diagnosis of cholecystitis.

Comment(s)

Clinical diagnosis using all the available clinical signs results is accurate at diagnosing cholecystitis. It seems that Murphy’s sign has high specificity, meaning that patients presenting with this sign are likely to have cholecystitis. Right upper quadrant pain may also be a good indicator of cholecystitis. However, at present it seems that no single clinical finding is adequate to diagnose or rule out cholecystitis

Clinical Bottom Line

If Murphy’s sign is positive in the presence of RUQ pain, this is sufficiently specific for a diagnosis of cholecystitis. If no Murphy’s sign is present, the patient may still have cholecystitis
