In clinical practice to label remission in the case of ulcerative colitis, all the features are needed, EXCEPT:: (A) Stool frequency <3 /day, (B) No bleeding, (C) No Urgency, (D) Normal looking mucosa in endoscopy
Answer is D. In clinical practice, 'remission' mean a stool frequency <=3/day with no bleeding and no urgency. Sigmoidoscopy to confirm mucosal healing is generally unnecessary. Ref: Journal of Crohn's and Colitis (2012) 6, 965-990
