Seems unusual. What is confusing to me is that the patient had a "total colectomy", but retained the ascending part of the colon. I don't understand a "total colectomy" that still has part of the ascending colon.

Typically after a total colectomy (which I had in 2021) one has the opposite problem of watery stools because there's no colon to absorb the liquid and make the stool semi-solid. In my case, they connected the end of the small intestine to the rectum.

Second, after a total colectomy there is no buffer space in the colon and one requires more frequent trips to the toilet.

Whether a total or partial colectomy, Metamucil or equivalent is a suggested therapy. For a partial colectomy, the fiber helps keep stuff moving. For a full colectomy, it's recommended to absorb the liquid and tighten it up.

One other thing - keep in mind that we're not medical professionals on this site, we're patients with real patient experiences.
