Actually no, his heart is fine. No issues there now. The doctors, from I gather, are concerned that something may rapture. Like I said he has a blocked bile duct as well. However, only his liver enzymes haven't come down.
Is your friend's heart very weak? Trying to figure out the risk. My friend had gall stones and she had a shunt put in and didn't have to go through major surgery. Her pancreas were inflammed and stomach swollen. She was on baby food for about a month, I believe.
