We studied correlations of pain measures in patients with either inflammatory bowel disease (IBD), a disease with a clear organic cause, or irritable bowel syndrome (IBS), a functional pain syndrome in which there is little demonstrable pathology. Correlations were determined between measures on the visual analogue scale (VAS) and on the McGill Pain Questionnaire (MPQ). The VAS score and present pain intensity scale (PPI) of the MPQ correlated well in the organic IBD but correlated poorly in the functional IBS. Differences in correlation between the VAS and PPI scores in functional versus organic disease did not appear to be due to altered sensory and affective pain components. This finding is similar to what we observed in our previous study of organic and functional pain syndromes in the musculoskeletal system. Correlations between the other measures are also discussed.

Irritable bowel syndrome (IBS) is defined as chronic-recurrent abdominal pain in absence of organic lesions. The crucial pathogenetic point is to establish whether pain is related to enhanced sensitivity of the patient or to an abnormal peripheral stimulus originating from the bowel. We can subdivide the patients with abdominal pain into two main groups: the first comprehends those patients with an abnormal response to a normal stimulus (i.e. an enhanced motor response to a meal) (irritable bowel syndrome) and second those patients who have a normal response to an abnormal stimulus (i.e. alimentary factors, laxatives, bile acids) (irritated bowel syndrome). On the basis of our knowledge we can say that the pathogenesis of IBS is complex and not yet completely defined. The crucial point is represented by our capability to discriminate between the "irritable" and "irritated" colon.

We studied 5 healthy volunteers and 9 patients with irritable bowel syndrome (IBS) during infusion of the colon with saline solution, bile acids, fatty acids and balloon distension. Our results show that the pain threshold was significantly (p less than 0.001) higher in controls than in IBS patients. Bile acids and fatty acids brought on the habitual pain in 5/7 and 7/8 patients respectively, while they did not have any effect in the control group. On the basis of our data we can conclude that the IBS patients are more sensitive to colonic distension and perfusions, thus suggesting a non-specific irritability of the colon which could be a characteristic of these patients.

Seventy-two patients complaining of abdominal pain were studied in a double blind trial with otilonium bromide (OB) (40 mg tid or placebo). In our patients we performed, before and after the treatment, a clinical evaluation (symptom variations) and functional studies (sigmoid manometry during bowel distension). As regards clinical parameters, otilonium bromide significantly reduced abdominal pain and bloating and significantly increased (p less than 0.02) the pain threshold. However the comparison with the placebo group did not show any difference between the two groups. Sigmoid motility during distension was significantly reduced (p less than 0.05) in OB group, whereas it did not change in the placebo group. We can conclude that, in irritable bowel syndrome (IBS) patients, OB is able to improve symptoms and to reduce stimulated motor activity of the sigmoid.

We studied 40 patients with irritable bowel syndrome (IBS) which received in a simple-blind fashion otilonium and pinaverium bromide (15 days each drug). During each 15-day period we evaluated: number of pain episodes, intensity of pain, number of bowel movements, side effects. Otilonium bromide, (OB), compared with pinaverium bromide was able to significantly (p less than 0.05) reduce the number of pain attacks, whereas no significant differences were found between the 2 groups as regards the other parameters. The occurrence of side effects was similar in the two treatment courses. We can conclude that the two types of treatment were similarly useful in IBS, although OB seems more effective than pinaverium bromide.

The autonomic nervous system may have a role in the pathogenesis of irritable bowel syndrome. If so, the occurrence of irritable bowel symptomatology in patients with autonomic neuropathy might indicate which, if any, of these symptoms are dependent on autonomic innervation. The prevalence of abdominal pain, abdominal distension and an abnormal bowel habit was recorded in 200 patients with diabetes, screened for autonomic neuropathy, and 200 matched controls. Constipation was significantly more common in patients with autonomic neuropathy than in those without, or controls (22.0% vs 9.2% vs 6.8%). The prevalence of abdominal pain and abdominal distension was no different in patients with and without autonomic neuropathy and their respective controls. The results of this study suggest that control of bowel habit is more dependent on the total integrity of the autonomic nervous system than the perception of pain or the production of distension.

Functional gastrointestinal disease is believed to be very common, but reports of its prevalence have not usually evaluated random community samples, and validated questionnaires have not been used to elicit symptoms. The prevalence of specific colonic symptoms and the irritable bowel syndrome among representative middle-aged whites was determined from a defined population, and the impact of these symptoms on presentation for medical care was measured. An age- and sex-stratified random sample of 1021 residents of Olmsted County, Minnesota, aged 30-64 years, was obtained. All subjects were mailed a valid self-report questionnaire that identified gastrointestinal symptoms and functional gastrointestinal disorders. The response rate was 82% (n = 835). The age- and sex-adjusted prevalence of abdominal pain (more than six times in the prior year) was 26.2 per 100 (95% confidence interval, 23.1-29.2). The prevalence of chronic constipation (hard stools and straining and/or less than 3 stools per week greater than 25% of the time) was 17.4 (95% confidence interval, 14.8-20.0), whereas the prevalence of chronic diarrhea (loose watery stools, and/or greater than 3 stools per day greater than 25% of the time) was 17.9 (95% confidence interval, 15.3-20.5). The prevalence of abdominal pain and disturbed defecation was similar in women and men, except that infrequent defecation and straining at stool were more common in women. Using the Manning symptom criteria to identify irritable bowel syndrome (greater than or equal to 2 of 6 symptoms in those with abdominal pain more than six times in the prior year), the prevalence of irritable bowel syndrome was 17.0 per 100 (95% confidence interval, 14.4-19.6). Overall, 71 persons (9%) reported visiting a physician for abdominal pain or disturbed defecation in the prior year; a subset of variables related to pain severity were the best predictors of health care seeking after adjustment for age and gender. However, these accounted for only 22% of the log likelihood. In conclusion, more than one third of an unselected middle-aged population reported chronic abdominal pain or disturbed defecation, and more than one in six had symptoms compatible with the irritable bowel syndrome. Only a minority had presented for medical evaluation; moreover, the characteristics of the abdominal complaints did not explain the seeking of health care in most cases.

One hundred two patients with irritable bowel syndrome were studied in a controlled trial of psychological treatment involving psychotherapy, relaxation, and standard medical treatment compared with standard medical treatment alone. Patients were only selected if their symptoms had not improved with standard medical treatment over the previous 6 months. At 3 months, the treatment group showed significantly greater improvement than the controls on both gastroenterologists' and patients' ratings of diarrhea and abdominal pain, but constipation changed little. Good prognostic factors included overt psychiatric symptoms and intermittent pain exacerbated by stress, whereas those with constant abdominal pain were helped little by this treatment. This study has demonstrated that psychological treatment is feasible and effective in two thirds of those patients with irritable bowel syndrome who do not respond to standard medical treatment.

Since it is not known whether the symptoms and bowel function of patients with the irritable bowel syndrome are truly abnormal we used diaries and frequent telephone interviews over a 31 day period to assess symptoms, defecation, and stool types in 26 unselected female hospital patients with the irritable bowel syndrome, 27 women who admitted to recurrent colonic pain but had not consulted a doctor (non-complainers), and 27 healthy control subjects. Unexpectedly, abdominal pain and bloating occurred in most of the control subjects. Pain, however, was six times more frequent in the patients and was more often considered severe. Bloating occurred three times more often. Defecation was more frequent, more erratic in timing and stool form, and more likely to produce stools of extreme forms, indicating rapid fluctuations in intestinal transit time. Urgency was four times more prevalent in patients than control subjects. Straining to finish defecating was nine times more prevalent and was often accompanied by feelings of incomplete evacuation--a combination which could lead to the misdiagnosis of constipation. The normal relation between stool form and the above symptoms was distorted, possibly due to rectal irritability. Non-complainers were intermediate between patients and control subjects in almost every parameter but were closer to control subjects than to patients. Patients with the irritable bowel syndrome have real cause for complaint and their bowel function is truly abnormal.

Fifteen patients with abdominal pain compatible with the irritable bowel syndrome (IBS) were examined by barium enema and pressure recording. Strong circular contractions of the sigmoid colon and pressure recordings correlated with the characteristic pain in 13 of the 15 patients. In 15 control patients no pain occurred. It is concluded that pain and high pressure are caused by strong circular sigmoidal contractions. Such findings enable the radiologist to contribute to the diagnosis of IBS.
