Respected doctor, my mother is having gallstones for 20 years which never caused pain and did not give any problem but since 10 days  she had been suffering from minor pain and developed jaundice. When I went to the doctor, he told me to get an ERCP done, another doctor told me open surgery would be required because it has been 20 years and it can't be operated through laproscopy. ERCP is expensive,we are not able to afford as it is done by private hospitals only at my small town.Mother's age is 70 years, the report is attached, please provide proper guidance.
