Remove surgically (6)
I believe the answer is:
resect
'remove surgically' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for resect that I've seen before include "Surgically remove a part of a structure or organ" , "Cut away or remove a bit of the body" , "Cut out tissue or part of an organ" , "Excise" .)
