If you were to name the 3 most important recent advances relevant for everyday practice in gastroenterology, what would they be?

Paul Moayyedi, BSc, MB ChB, PhD, MPH: So, the most important developments in gastroenterology over the last few years… I feel [it] is the understanding that the microbiome is associated with many diseases. Certainly, it’s important for ulcerative colitis. We have shown this and we’ve shown this because fecal transplants work in a proportion of people with this disease. We showed it in our group, and 4 other studies have confirmed these findings.

This, I think, is important and also highlights another area that is important, which is fecal transplants, which have been very useful in the treatment of Clostridioides difficile–associated diarrhea, particularly [if it] was resistant to antibiotics. But, as I say, we will probably find this approach emerging [as effective] for other diseases but not [in] as many as are being tested at the moment. You know, the press seem to feel this will treat everything, which it will not, but it certainly will be useful, I feel, for some patients with some diseases.

Our treatments will develop further. So, we will understand what gut bacteria are driving this change and indeed what gut bacteria [are] driving disease. So, gastrointestinal (GI) diseases in the future may be a lot more [frequently] treated with both targeted probiotics and antibiotics, with a greater understanding of what is driving disease and therefore [with] a lot better [management] than what we’re doing at the moment.
