Desire shown among surgeons (4)
I believe the answer is:
urge
'desire' is the definition.
(I know that urge is a type of desire)
'among surgeons' is the wordplay.
'among' indicates the answer is hidden within the clue.
'URGE' is hidden in the letters of 'surgeons'.
'shown' acts as a link.
(Other definitions for urge that I've seen before include "Sudden desire" , "Implore" , "Appeal to" , "Press; drive" , "Advocate" .)
