Lancet Gastroenterol Hepatol 2022; 7: 617-626.
Some 95 patients were included in this trial. After 18 months, radiological (MRI) healing was higher after surgery with anti-TNF (32 per cent) than anti-TNF alone (9 per cent); P=0.005. In contrast, clinical closure rates were reported as similar: 68 versus 52 per cent, respectively.
Comment: Shouldn’t there have been a surgery only arm for the perfect trial?
