In the UK a 'surgery' is where you go to consult your doctor (GP).
It's a somewhat confusing term as surgery isn't carried out there at all, with the possible exception of a small number of very minor procedures.
Members of Parliament make themselves available for constituents to consult them at various locations, and have borrowed the term, so refer to these sessions as 'Constituency Surgeries'.
