An operation (noun), operate (verb), perform surgery (perform is the verb, surgery the noun), the GP's surgery is on Random Street (surgery is a noun refering to a place in which consultations take place but no surgery is carried out (or occasionally very minor procedures under local anesthesia). Procedures - noun.
I suppose "surgeries" makes as much sense as "operations" and "procedures" - all the words have more than one meaning (building in which a GP or even member of parliament consults with patients/ constituents, military operation, any kind of procedure including in business, certainly not only medical.
I agree using surgeries to mean surgical procedures / operations sounds daft to my ear. It sounds awkward and forced and out of place used that way. Sometimes people seem to want to use a different word to imply greater experience, but actually convey the opposite.
I suppose if it's what you're used to it doesn't sound so incongruous.
Is it the word used in American hospital dramas?
