Dang! Not really. I'm wondering the difference if any between a diverticula and a crypt in the colon? I "thought" at first of "rectal crypts" which I have heard of (had one myself that required a "rectal cryptectomy" years ago when I didn't know anything and 5 years before my Crohn's symptoms and Dx). I would think pathologists would differentiate between the colon and the rectum but ... I would also "think" that a pathologist would differentiate between an ulceration, a crypt and a diverticulum. I'd say this is something you would have to discuss w/your gastro to get a clear answer.
Some people are like Slinkies... Not really good for anything, but they still bring a smile to your face when you push them down a flight of stairs.
