"P: perianal"
"P is a modifier that can be added to B1, 2 and 3 when concomitant perianal disease is present"
"S0: ulcerative colitis in clinical remission; no symptoms of UC"
"S1: mild UC ≤4 bloody stools daily, lack of fever, pulse 105 g/L, ESR"

"Ulcerative colitis did not have specific sub-classifications listed in the Vienna and Rome classifications, which were introduced with the Montreal classification system. The existing limitation of these classifications is that they capture a snapshot of the disease state rather than longitudinal data, which is important given the dynamic nature of inflammatory bowel disease 1."
Expected headings
"Classification system"
"Crohn disease"
"Ulcerative colitis"
"Crohn disease has three categories, including age of onset, location and behaviour. Age of onset and location are descriptive in nature, whereas an increase in the behaviour subcategory provides an indicator of disease severity; similarly, in ulcerative colitis."
"P is a modifier that can be added to B1, 2 and 3 when concomitant perianal disease is present"
"The Rome classification in 1991, proposed by the International Working Party, suggested a classification system based on disease extent, anatomical location, behaviour and operative history 5,6. This was subsequently revised in Vienna at the World Congress of Gastroenterology in 1998 (and subsequently known as the Vienna classification), which introduced age of onset as well as including anatomical location and disease behaviour 6."
"Crohn disease has three categories, including age of onset, location and behaviour. Age of onset and location are descriptive in nature, whereas an increase in the behaviour subcategory provides an indicator of disease severity; similarly, in ulcerative colitis."
"E1: ulcerative proctitis; involvement limited to rectum (rectosigmoid junction)"
