[|AI|]  Hi, I had gone through your question and understand your concerns. It is obvious that your father had multiple stones in common bile duct which caused complicated clinical scenario and after these procedures there is always a possibility that there is retained stone or again or that stenosis of bile duct occur. This is why balloon sphinterotomy should be done to dilate bile duct. This is much less risky procedure compared to ERCP and surgery, so you should not be worried about complications. Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
