It’s a full-fledged IV-in, anaesthesia using, no eating after midnight procedure. They clean it up and recut the edges and something. I’m not sure what all is involved, but new stitches alone wouldn’t help.
If he is using the area too soon after surgery, tie him down or something. (semi-joke) If he is obeying the doctors orders talk to the doctors and find out what you/he can do. This doesn’t sound like a good thing. Maybe the repeated surgeries are not a good idea - the wound edges are too clean to heal correctly? When I cut my arms open several years ago trying to remove an air conditioner alone (note: DO NOT TRY THIS) the doctors did very little cleaning of the edges and told me a rip will heal more quickly than a razor cut.
I’m not taking any pool bets, because mine would be that it will never open again. My thoughts are with you and your hubby.
