800 Kilobear -There are other treatments like Actigall -takes upto two years and only works half the time. They can do lithrotripsy (ultrasound breaking up the stones) -this works about 35% of the time. Now they have Gastros that will go in there during endoscopy and zap them with either laser or US.

The easiest way to treat this disease is with laparoscopic surgery. I viewed quite a few and it’s a real simple procedure with a very low rate of complications.
