<s>[INST] i had my gaul bladder removed about 3 years ago, ive had nothing but trouble since i now have blocked bile ducts , ive had stents put in but these have not worked the doctors tryed to re do the stents for a 3rd time and were unable to get any in , i had a MRI scan done the other day the results were normal is this normal [/INST] Hi,It may be caused by 3 issues. First, there may be stone in common bile duct and it should be removed with ERCP or another surgery. Second, it may be tumors and third it may be stenosis. You need to do ERCP and if there is stenosis or blocakage and then further treatment can be planned. Wish you a good health.Hope I have answered your query. Let me know if I can assist you further.Kindly regards,Ivan R. Rommstein </s>
