@CTBarrister, I've been scoped many a time over the years, and my problem was usually due to a stricture, or so my surgeon told me over the years, which was dilated during office visits. But it didn't quite make a difference, which is why I'm pretty sure it's due to food volume.
Two years ago I had a full workup with the King of Pouches, Dr. Bo Shen, at the Cleveland Clinic and he said I had Paradoxical Contractions (as well as a bit of a Floppy Pouch) and needed 10 straight sessions of Physical Therapy, which I did. I had learned that I wasn't using my pelvic muscles properly to properly evacuate. So even though I'm more mindful now of evacuating properly, I still have problems which is why I'm sure it's from too much food volume and also because of my minor Floppy Pouch.
Dr. Shen did not find any strictures at that time. Now that he is in NY and much closer to me than the Clinic in Ohio was, I must make an appointment with him, but Covid interfered with a lot of plans.
In all of Bo Shen's literature, it is stressed to eat SMALL meals! I would join an overeaters anonymous group but they would look at me funny because I'm on the thin side, heh. Maybe if there are enough people in this group who have the same problem with eating we can all give each other encouragement.
