ARTICLE HIGHLIGHTS
Research background

The Rome IV criteria eliminated abdominal discomfort for irritable bowel syndrome (IBS), which was previously included in the Rome III criteria. Asian studies showed the rate of IBS patients with abdominal discomfort alone was high.

Research motivation

There are questions as to whether IBS patients with abdominal discomfort (seen in Rome III but not Rome IV) are different from those with abdominal pain (Rome IV).

Research objectives

To compare the bowel and extraintestinal symptoms of patients with IBS presenting with abdominal discomfort alone to those with pain alone as well as with pain & discomfort and to evaluate the anxiety, depression, quality of life, and symptom reporting tendency for patients with pain and discomfort.

Research methods

We enrolled IBS patients and collected their clinical data. Patients were classified to the pain only group, the discomfort only group, and the pain & discomfort group. We compared bowel symptoms, extraintestinal symptoms, IBS-quality of life, psychological status and healthcare-seeking behaviors, and efficacy among the three groups and tested risk factors for symptom reporting in IBS patients.

Research results

About one-third of patients meeting Rome III criteria failed to meet Rome IV criteria for an IBS diagnosis. There were no meaningful differences between the pain group and discomfort group for frequency of defecatory abdominal pain or discomfort, bowel habits, coexisting extragastrointestinal pain, comorbid anxiety and depression, and IBS-quality of life scores.

Research conclusions

IBS patients with abdominal discomfort have similar bowel symptoms and psychosocial features to those with abdominal pain.

Research perspectives

Further studies focused on the pathophysiology and therapeutic response (including the cultural influence) of abdominal pain and discomfort are needed.
