I will just share my knowledge about this:

Your husband might have the gallstones(Cholelithiasis), we just hope that the stones are just in his gallbaldder and not in the tubes.Lap cholecystectomy might be the operation which will just take an hour or more than an hour. They will make a 4 holes, sometimes its 3 in his abdomen which these small holes are the portal of entry of the tubes to be use in the operation, they will use the fiberoptic surgery( the use of camera and the monitor)to view any hallow organs or tissues. and they will use clippers also, and the rest will be fine.

when the operation is done then just be careful of the complications that might come in.. if he feels pain after the operation it might be cause by the carbon dioxide inserted in his abdomen, nothing to worry because it will go by itself to consider also the surgical sites which can be controlled by medicines....but be assured that your doctors will monitor your husband..better to bring him to a hospital which you can have doctors to see him 2 times in a day, which i think you cannot find in the government hospitals here....

ignore the statement below...
(The worst I have seen is the walk-in clinic of Hamad Hospital for bachelors..and other hospitals which only cater family.. where in the hell can you find these kinds of treatment? only for emergency...gosh..only here in Qatar..really the worst of all the health care institutions are here, they really are rich with the technologies they have but they are not rich of the minds on how to use, or to impart those they have..they are selfish..)why they created such hospitals if dont cater sick people..?? really a big question in my mind..)

just pray...fast recovery for him.
