So my father had urgent surgery last week because of a very strong attack of pain on the upper-right part of the stomach. He is diabetic and we knew he had gallstones because of an ultra-sound he did at the start of the month following some blood-tests with high gpt (like 500). He had some fatty-liver problems back in the day that he managed to get in check and we thought it was that this time too causing the high liver enzimes, but as it turned out in the ultra-sound it was gallblader stones. So doctors say it must be extirpated and they proceed to do it. After the fact, the surgeon tells us it went perfectly by laparoscopic, but he remarks that the gallblader was really infected and the liver is quite weakened. A couple days after surgery my father is fine, no pain, no symptons, he eats and goes to the bathroom normally. They put him in antibiotics for the infection and run some bloodtests. Turns out GPT is now 800. They proceed to do a Magnetic Resonance Cholangiopancreatography to check if there are any stones left that went out of the gallbladder and find there is nothing and everything is okay. Bloodtest results come out today and his gpt has once again increased, this time to 1000. I’m quite scared because it does not seem that his enzimes go down and its been a week since he got the bladder out. Is he still having post-inflamatory issues from the surgery? Is it the antibiotics? Has his liver an autoinmune illness? He is perfectly fine and test keep coming bad despite what Internet tells me post-surgery gallblader is like and what are usually the times for medical discharge. Has this happened to you? Is this normal?
