It doesn't make it right to lose synthetic baits for fish to ingest, but fish can pass fairly large and complex items through their system, as can be sen from the picture below
When I landed a 2Lb plus rainbow at the Frandy Reservoir last year, a booby was dangling from the anal vent of the fish, attached to 4 feet of leader, with 3 feet of the leader hanging from its mouth. The booby had amazingly passed through the trout's digestive system and the hook was as black as the ace of spades. The booby complete with leader was gently pulled through the fish and it was released unharmed, hopefully to fight another day
