biliary calculus

A gallstone, or biliary calculus.

So remarkable was the conjunction of symptoms in these two attacks that a strong suspicion of biliary calculus was raised, but not the slightest confirmation of this idea could be obtained; and indeed one symptom—vomiting—which nearly always attends the painful passage of a biliary calculus, was altogether absent.

Under these circumstances she was attacked with intermittent pains, in the right hypochondrium, of intolerable severity; resembling, in fact, the pain of biliary calculus, but without the sense of abdominal constriction, and without any vomiting.

This is all the more necessary because now, in patients' minds, the words appendicitis or biliary calculus are associated with the thought of operation.

Practically all the symptoms of the presence of biliary calculus may be thus simulated.
