<s>[INST] Hello sir, I am here for my mother. age 55 yrs. she has gall stone and also issues with her main portal vain. Drs in Kolkata asked for not go for a laproscopic operation  and suggested to move to vellore. Looking for suggestion for good drs in CMC vellore [/INST] Hi thanks for asking question. You have not mentioned how much gall stone present whether single or multiples?? Is there abdominal pain present??? If stone is single and asymptomatic no need for gall bladder removal... Close clinical follow up done.... If gall stone troublesome and complicated ex. Lead jaundice, repeated infection then it is removed.Meanwhile, take low fat diet. Udiliv can be helpful... Take care.... Chat Doctor.  </s>
