Greetings.
If the bile does not flow to gallbladder it does not cause pressure on the liver or pancreas. The gall bladder function is to store the bile and when we eat food this stored bile is liberated. But some bile is flown through the common bile duct which comes from the liver, throughout the day. So despite the flow to gallbladder being blocked the common bile duct (CBD) keeps on flowing the bile from the liver and not causing the pressure or pent up bile. Gall stones, pain and the cystic duct (through which bile flow to gallbladder) being plugged/blocked, are all indications for the removal of gall bladder (cholecystectomy). Still before the surgery esophagogastroduodenoscopy (upper GI endoscopy) is essential to rule out any other associated pathology/disease.
