Diagnostic Considerations
Manning and associates established 6 criteria to distinguish irritable bowel syndrome from organic bowel disease.[13] Although historically important, these criteria are insensitive (58%), nonspecific (74%), and less reliable in men. The Manning criteria are as follows:
- Onset of pain associated with more frequent bowel movements
- Onset of pain associated with looser bowel movements
- Pain relieved by defecation
- Visible abdominal bloating
- Subjective sensation of incomplete evacuation more than 25% of the time
- Mucorrhea more than 25% of the time
Other problems to consider include the following:
- Fructose intolerance
- Gastrinoma
- Infectious colitis
- Medication adverse effects
- Secretory diarrhea
- VIPoma
