I had my gall bladder removed 4 months ago at AlEmadi hospital. The operation was no problem and the pain dissappeared straight the way. Your husband will end up with 3 small scars on his abdomen,
Recovery is very quick although it took me longer as I had a pancreatitis caused by a stone that had entered the bile duct,
You should be able to go back to a normal diet afterwards although I found that I cant eat very much red meat without getting stomach pains, Otherwise everthing is fine
I sympathise with your husband as i know how very painful gall bladder problems are,
Do not try the homeopathic route it can make it worse and if a stone moves like mine did you will be in for a whole load more pain and complications
