Theatre work that could have you in stitches (7)
I believe the answer is:
surgery
'theatre work' is the definition.
(work in an operating theatre)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for surgery that I've seen before include "GP's place of work" , "Doctors' practice" , "Medical intervention" , "Branch of medicine" , "Doctor's (or MP's) place of business" .)
