Recently I was told I had a stone in my bile duct. The surgeon says I should
undergo surgery. Are there any other options?
Yes. First, change your surgeon. The first choice to remove stones in the bile duct is ERCP. This is a procedure with a scope and most GI doctors perform it. However better get someone who is experienced. You will be admitted overnight and discharged the next day. With a scope, a basket it used to remove the stone. If this fails, you can use surgery. Surgery is not the first choice for removal of bile duct stones and it seem that this surgeon only appears interested in giving you a big scar and wanting your money. Dump him/her.
