> [...] the treatment, which involved a bowel cleanse and daily transplants of fecal microbiota over a period of seven to eight weeks

Maybe I'm misinterpreting what the process of that daily transplant looked like, but I expect they ate a not insignificant amount of hospital food if there were 7-8 weeks of daily treatments.

In my experience (instant cure for recurrent c. diff) a fecal transplant is easier and simpler than a colonoscopy, which themselves are easy enough to be outpatient.
