Gallbladder removal malpractice (yes,no)

Hi, I whent to the hospital with pain and they suggested to removed my gallbladder due to it having stones, it was done 11am that day and I was told to go home the same day a few hours later. I was fine with it had some pain. But it was bareble, a day's after the surgery I had huge pain even with the pain killers I had fever etc. I call ambulance was rushed to the hospital they just gave me morphine and did a ct scan and send me home. So I keep getting these pain and final 3 days later I couldn't take it and when back to the hospital and they notice my white cells where high and my pressure was about 170, a young doctor intern check me and said I migh have a stone still in my liver. And they send me to get a endoscopy(rush me in) since my liver and pancreas was failing. I am wondering if I have a lawsuit case here or not since they left a piece of the gallstone in my liver which caused my liver to rupture and drop bile all over my body, I could of died really all my stats were horrible. I am 29 years old I workout regurly and eat healthy 80% of the time all my blood work was perfect till the surgery.
