She's still in surgery, but per her husband about 30 min ago "Progress report from the OR. Everything is going well and no problems have surfaced."
As expected, showing up at 6 AM was for a surgery start time of about 8 AM Eastern time, so it's been about 4.5 hours since she was taken into the OR - not surprising in view of her size and the number of procedures (stomach, intestines, cholecystectomy and appendectomy) being done. I wouldn't be surprised if Elariny finds and repairs a hiatal hernia in the process as well (everyone in the family has reflux, and Dad had a hiatal rupture a few years ago - most of his stomach abruptly ended up above the diaphragm). So I'm not concerned about the time just yet.
I'm expecting a post-op update shortly.
