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).AIM To compare bowel symptoms and psychosocial features in IBS patients diagnosed with Rome III criteria with abdominal discomfort, abdominal pain, and pain &discomfort.METHODS We studied IBS patients meeting Rome III criteria. We administered the IBS symptom questionnaire, psychological status, and IBS quality of life. Patients were classified according to the predominant abdominal symptom associated with defecation into an only pain group, only discomfort group, and 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. Finally, we tested risk factors for symptom reporting in IBS patients.RESULTS Of the 367 Rome III IBS patients enrolled, 33.8%(124 cases) failed to meet Rome IV criteria for an IBS diagnosis. There were no meaningful differences between the pain group(n = 233) and the discomfort group(n = 83) for the following:(1) Frequency of defecatory abdominal pain or discomfort;(2) Bowel habits;(3) Coexisting extragastrointestinal pain;(4) Comorbid anxiety and depression;and(5) IBS quality of life scores except more patients in the discomfort group reported mild symptom than the pain group(22.9% vs 9.0%). There is a significant tendency for patients to report their defecatory and non-defecatory abdominal symptom as pain alone, or discomfort alone, or pain & discomfort(all P < 0.001).CONCLUSION IBS patients with abdominal discomfort have similar bowel symptoms and psychosocial features to those with abdominal pain. IBS symptoms manifesting abdominal pain or discomfort may primarily be due to different sensation and reporting experience.展开更多
