A surgical procedure that creates an opening in or drainage from the liver, typically to treat infection or obstruction within the liver tissue itself.
From hepatic- (liver) + -stomy (surgical opening). This more general term can refer to any procedure creating a liver opening, distinguished from the more specific terms that specify where the bile is drained to.
The difference between hepaticostomy and something like hepaticoduodenostomy is like the difference between making a general exit hole versus a specific tunnel to a destination—one just relieves pressure, the other creates a functional new pathway.
