Its genetic. Mother had her's out in the 60's. 10" scar. I remember, cus Daddy was on flight duty and gone, and I held down the fort while Mother was in the military hospital for two days. I was in 6th grade.
DD had an attack when she was 30. Yanked it out. Three holes in the belly.
Niece last week, two days after her 32nd bd, had an attack. They yanked it out. Sent her home the same day. The next day she was back, admitted to the hospital, cus some of the tiny stones worked their way into her pancreas. Very dangerous to that organ. She went home three days later.
Don't wait, Tortoise, when the time comes.
