Advice
  • Use the classification results to tailor treatment options, such as immunomodulators, biologics, or surgery, based on disease severity and phenotype.
  • Incorporate classification results into multidisciplinary discussions, including gastroenterologists and surgeons, to optimize patient care.
  • Monitor disease progression and reassess the classification periodically, particularly in cases of changing clinical presentation or treatment failure.
  • Do not use this tool as the sole determinant of management decisions; clinical context, patient history, specialist consultation, and other diagnostic tools are essential.
  • For more detailed management recommendations, please refer to regional guidelines, such as those from the American Gastroenterological Association, American College of Gastroenterology, and American Society of Colon and Rectal Surgeons.
