Secrete via worming gut (10)
I believe the answer is:
'gut' is the definition.
'secrete via worming' is the wordplay.
'worming' indicates an anagram (letters worm or wriggle around).
'secretevia' is an anagram of 'EVISCERATE'.
(Other definitions for eviscerate that I've seen before include "Disembowel" , "Remove essential parts" , "Draw" .)
