Cholecystocolotomy

A surgical procedure involving incision into both the gallbladder and the colon, often to remove stones or relieve obstruction.

From Greek 'chole' (bile) + 'kystis' (bladder) + 'kolon' (colon) + 'tome' (incision). The '-otomy' suffix indicates cutting or making an incision, distinct from '-ostomy' which means creating an opening.
