Jan 10th. So far a stent was placed for two weeks, then removed. It's out, the hole is still there and the endoscopic surgeon is doing another procedure on March 2nd, but this procedure will not close the hole and may involve placing a stent through the hole which will further delay the closure.
I am an engineer and can't believe in the year 2017 there is not a patch, plug, adhesive, fastener or other method to close a hole.
