Here We Go Again...

I think it is diverticulitis - little out pouches in the colon that can capture waste and become inflammed and bleed or even burst (which is not good, but doesn't happen very often). The polyps could have been bleeding too, so with them removed, that could help.

Usual treatment might be antibiotics if the pouches are inflammed, if spasms or pain is present, then other meds to reduce those symptoms are prescribed. Also, a bland, liquid or low fiber diet may help.
