If you were fine on pantoprazole for 4 weeks and only then developed urgency and watery stools then I'd guess it's not the most likely cause, though it's possible. You could try changing acid reducing medication to see if things improve. Have you ever had these symptoms before? Has anything else changed? For me urgency usually signals pouchitis - is that possible, do you think? The rectal steroid makes pouchitis less likely, though.

Now I remembered, 4 years ago I had green stools and similar symptoms and I had Ciptosporidium and Entamoeba hystoliticia parasites. Green stool that apparently passes quickly like now, without smell. I read that it passes spontaneously, I don't remember if I took any therapy for them then. I generally go with the hypothesis that Mazda's lack of gastric acid helped in several infections.

This certainly could be a GI infection (viral, bacterial, or parasitic), particularly if you are exposed to questionable food or water. While some GI infections do clear up on their own it’s much wiser (if it persists) to find out what you’ve got and treat it, when appropriate. Some of them don’t clear up without treatment, and some of them can cause significant complications.

Yes, I understand your logic.  I'm taking stool samples for analysis on Monday.  The doctor gave me "metro" 400 mg x3

I’m glad you’re getting tested. It is sometimes a mistake to start treatment before testing, since it can sometimes cause the tests to give a false negative result, even though the treatment may not be quite right. OTOH sometimes waiting for the test without treatment can be a problem, too.

@Enterin You posted the link without explanation. Did you get a diagnosis?

Not, everything is negative, I need to take the stool 2 more times for parasites. I hope that the "metro" antibiotic did not camouflage something
