Each time people have a "gall bladder attack", the body can lay down scar tissue which can make removal more difficult. Also, if a stone becomes lodged in the cystic duct, an ERCP may also become necessary to remove or dislodge it.

I'd imagine everyone is aware of the opiate issues for patients which results in accountability for providers and tighter control over numbers of opiate pills made available to patients--who may or may not be taking them for legitimate or illegitimate reasons. It can become medical quicksand.
