Understanding the Rome IV: Irritable Bowel Syndrome and Functional Diarrhea / 대한내과학회지

Irritable bowel syndrome (IBS) is a common, chronic functional gastrointestinal disorder affecting the large intestine, and presents as abdominal pain and/or discomfort, bloating, gas retention, diarrhea, and constipation. IBS impairs quality-of-life and requires long-term management. In 2016, the Rome Foundation introduced new IBS diagnostic criteria (the Rome IV criteria), and also revised the diagnostic algorithms for, and the multidimensional clinical profile (MDCP) of, functional gastrointestinal disorders. The IBS MDCP includes clinical data, the extent to which normal daily activities are affected, and psychosocial and physiological measures. The criteria seek to aid physicians in choosing appropriate treatment for IBS patients. Herein, we seek to provide evidence- based practical information on IBS and functional diarrhea. We review the new Rome diagnostic IV criteria, the MDCP, and the various IBS treatment options. We suggest that, in clinical practice, combination therapies may be useful to treat patients with IBS of various grades.

Understanding the Rome IV: Functional Constipation and Anorectal Disorders / 대한내과학회지

We used mainly the Rome diagnostic criteria to diagnose functional gastrointestinal disease (FGID). The revised Rome IV was announced in 2016. Rome IV is the recognition that a considerable overlap exists between some of the FGIDs and that they may exist as part of a spectrum, rather than discrete disorders. Based on this concept, the Rome IV criteria for functional constipation and anorectal disorders are newly revised. We review the background and content of the Rome IV diagnostic criteria and introduce the multidimensional clinical profile using clinical cases. These revised criteria will be helpful for adequately diagnosing and managing these patients in actual clinical practice.
