Glad that's done and dusted for him .
Now it's "just" the recovery time.
As Chris says please tell your husband to be careful. Healing inside will take a long time and it's easy to over exert yourself after the op partly due to relief that it's all over and partly to prove to yourself that you are strong enough to recover quickly.
It's not a race, he'll do better in the long run if he takes it slow and steady, gradually increasing his activities without exhausting himself.
Best wishes for a speedy recovery
