I can answer that. Most likely, no. This is not like unbunching your panties, where you just undo the kink. That is what happens when you have the occasional partial obstruction that rights itself.
With prolapse, it is a structural defect that occurs over time due to ongoing weakness, pressure and/or narrowing. Like an over-stretched pouch or weak pelvic floor, it cannot be manipulated back in place.
If it is due to adhesions or stricture, the hope is that the tissues return to normal position after the the cause is dealt with. But, if it has gone on too long, only surgical repair can restore the proper shape and alignment.
Most likely, these things are mot visible on scope, because they inflate your pouch with air for visibility, taking away the effect of gravity and internal pressure. That is except for a stricture. That could be seen.
