Brief Answer:
Do not do surgery for stones if it is not emergency

Detailed Answer:
Hello,
let me explain you in detail as pancreatitis is not your primary problem
1) Portal vein brings blood to liver (80%) and this vein is blocked due to some reason in your case. But to continue supply of blood to liver, small veins are formed around blocked portal vein which supply blood to liver.
2) portal vein is formed by fusion of two veins one brings blood from small intestine and other brings from spleen. The vein which brings blood from spleen also bring blood from pancreas. In your case, these both veins are also blocked. Ultimately, patient develop portal hypertension.
3) In portal hypertension, small veins at lower end of esophagus become enlarged and may cause vomiting with blood.
4) Therefore you should do upper GI endoscopy and clipping of these small esophageal veins to prevent bleeding.
3) This blockage of portal vein is genetic disorder and it is irreversible. Medical treatment is only helpful to prevent damage to liver otherwise ultimate treatment is liver transplantation or surgery for diversion of blood flow from portal vein to other vein of body
4) About gall bladder stone - never do any surgery on abdomen until it is emergency because bleeding is very severe risk for any abdominal surgery in these patients.
