A surgical procedure involving incision into both the stomach and the elytra, sometimes used in veterinary medicine.
From 'gastro-' (stomach) + 'elytro-' from Greek 'elytron' meaning sheath or covering (referring to hardened wings in insects) + '-tomy' meaning incision.
This is such a rare surgical term that it's almost exclusively found in old veterinary or entomological surgical texts—most modern surgeons wouldn't even recognize it, which shows how medical language constantly evolves!
