My mother had gallbladder stones is there any treatment rather then surgery?

Not really: you can try to manage the pain by medication, you can even try the medication that might be able to dissolve some specific stone,but you could not make the gallbladder healthy again.if the patient is healthy enough to tolerate surgery . Then surgery is the only cure for this problem,that will eliminate any potential complication associated with gallbladder stone. All other option are palliative .
