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.

The effects of prokinetic treatment with cisapride in patients with constipation-predominant irritable bowel syndrome (IBS) were evaluated in a randomized, double-blind, placebo-controlled study. Sixty-nine IBS patients were assigned to a 12-week treatment with either 5 mg cisapride or placebo t.i.d.; this dosage could be changed if necessary. The mean weekly number of days on which a stool was passed in the cisapride and placebo group increased to 5.3 and 4.4 (p less than 0.05) during weeks 8-12 of treatment, and the number of days with stools of normal consistency increased to 3.5 and 1.9 (p less than 0.05), respectively. At week 12, the reduction in severity and frequency scores for abdominal pain was significantly greater (p less than or equal to 0.05) in the cisapride group (60 and 61%) than in the placebo group (40 and 32%), as it was for abdominal distension (p less than 0.05). Cisapride tended to be better than placebo in diminishing flatulence. In 71% versus 39% of the patients the overall rating for the response to treatment was good or excellent at week 12. Cisapride was well tolerated. These results suggest that the drug will be useful for the management of constipation-predominant IBS.

Among medical clinic patients consulting for IBS, symptoms of psychologic distress are common, and more than half of these patients are found to have a psychiatric diagnosis in addition to bowel dysfunction. Many investigators have therefore concluded that IBS is a psychophysiologic disorder and proposed that patients with IBS be treated with psychologic techniques. However, recent studies suggest that this association may be spurious; persons in the community who have symptoms of IBS but do not consult a doctor have no more psychologic symptoms than persons without bowel symptoms. This indicates that psychologic symptoms do not cause bowel symptoms, but, instead, influence which persons with bowel symptoms will consult a physician. The bowel symptoms and the psychologic symptoms that coexist in most patients with IBS may be best thought of as comorbid conditions. Neither causes the other, but both may be serious enough to warrant treatment. Moreover, in some patients whose bowel symptoms consist of vague complaints of abdominal pain not specifically related to defecation or to changes in the frequency or consistency of bowel habits, the psychologic disorder may be primary. Psychologic stress may exacerbate IBS whether or not the patient has a psychiatric disorder, and psychologic stress may trigger acute episodes of symptoms similar to those of IBS even in persons without IBS. However, the magnitude of this correlation is modest, suggesting that only about 10% of the variation in bowel symptoms is attributable to stress. Psychologically oriented treatments have a role in the management of IBS. Most patients who consult internists about bowel symptoms have significant levels of depression and anxiety, and they tend to notice and to worry about somatic complaints more when they experience these dysphoric affects. Psychologic treatments that reduce the level of their psychologic distress also frequently reduce the frequency and severity of complaints about bowel symptoms. Tricyclic antidepressants may be tried as a first line of treatment; they have been shown to be superior to placebo for the management of abdominal pain and diarrhea but not constipation. In patients who do not show an adequate response to antidepressants, brief psychotherapy focusing on better ways of coping with current problems, hypnosis, or behavior therapy emphasizing methods of controlling reactions to stress are recommended. Controlled trials show these treatment approaches to be superior to medical management alone. It may appear paradoxical that psychologic treatments aimed at the management of emotions are so frequently found to reduce bowel symptoms, because the motility disorder responsible for the bowel symptoms may be unrelated to the psychologic symptoms that influence the patient to seek treatment.+4

This placebo controlled, double-blind, cross-over trial involving 20 patients was conducted to assess the effect of ispaghula husk on the major bowel symptoms and the whole gut transit time in irritable bowel syndrome (IBS) and to determine if changes in these parameters were related to global improvement. All 20 patients were interviewed at the end of the treatment periods and 14 patients kept concurrent daily records. Ispaghula therapy resulted in improvement in global symptoms and satisfying bowel movements (P less than 0.001) but produced no change in abdominal pain or flatulence. There was a correlation between the improvement of well-being and the number of days of satisfying bowel movements (P less than 0.001) but not with the indexes of pain, stool frequency or changes in the transit time. The easing of bowel dissatisfaction appears to be a major reason for the therapeutic success of ispaghula in IBS.

A retrospective study on the syndrome of chronic diarrhea was carried out on 50 revised clinical histories. The patients were hospitalized at the E. Rebaglati M. Hospital between April 1983 and March 1988. The purpose of the study was to evaluate the signs and symptoms of the syndrome, as well as the etiological agents and the methodology used for diagnoses. The selection criteria involved patients diagnosed as suffering from "chronic diarrhea of undetermined causes" upon entry. Seven were excluded due to incomplete study whereas 2 were diagnosed as acute infections diarrhea. Forty one patients were definite cases of chronic diarrhea and they were divided between 2 groups: the first one or Chronic Organic Diarrhea (58.53%) and the second one or Chronic Functional Diarrhea (41.46%). Out of the 41 revised clinical histories with chronic diarrhea, the following were the foundings: (1) the syndrome affects the economically active populations mainly and the length of the disease was more than 3 weeks in all the patients; (2) anemia, fever, weight loss, nightime bowel movements and bloody stools suggest organic problems whereas psychiatric disorders, daytime bowel movements, abdominal pain, disease recurrence and absence of detectable organic pathology suggest functional problems; (3) the most common cause of chronic diarrhea is the Irritable Bowel Syndrome followed by infectious diseases, with parasitosis in the first place; and (4) bearing in mind the mainly colonic affection and the predominant infectious diseases, the methodology used for their diagnosis would bring out good results.

Thirty-nine hospital outpatients with upper abdominal pain without demonstrable organic abdominal abnormalities and 28 healthy controls were compared blindly with regard to back pain and back abnormalities when subjected to a standardized physical examination of the spine. Seventy-two per cent of the patients versus 17% of the controls were troubled with back pain (P less than 0.001). Seventy-five per cent of the patients with back pain actually had abnormalities revealed at the physical examination, indicating that some organic mechanisms are involved in back pain. Most of the findings were localized to the lower thoracic and thoracolumbar segments, the same segments that innervate the upper gastrointestinal tract. This suggests the existence of a connection between abdominal pain and back pain. Viscerosomatic or somatovisceral reflexes with trigger zones either in the viscera or in the skin, muscles, tendons, or ligaments could be part of the pathophysiology in this syndrome. Fifty-one per cent of the patients had symptoms of irritable bowel syndrome, and 41% had heartburn, which was significantly related to the experience of back pain.

OBJECTIVE To compare the efficacy and acceptability of mebeverine and high-fibre dietary advice versus mebeverine and ispaghula in fixed combination in the treatment of irritable bowel syndrome in adults. DESIGN Open, prospectively randomised, parallel group comparison of mebeverine/dietary advice and mebeverine/ispaghula during an eight-week study period. SETTING General practices in the UK. PATIENTS One hundred and eleven patients with irritable bowel syndrome diagnosed by symptom profile or negative investigations between the ages of 18 and 75 years were entered. All patients had a history of abdominal pain occurring at least once a week for a period of three months or more. INTERVENTION Dosage was 135 mg of mebeverine hydrochloride, three times daily before meals, together with advice on high-fibre dietary intake, or 135 mg of mebeverine hydrochloride plus 3.5 g of ispaghula husk twice or three times daily before meals. MEASUREMENTS AND RESULTS Details of abdominal pain severity and frequency, bowel frequency and stool consistency were recorded by means of clinicians' assessments and patient diaries. Pre-treatment assessments revealed no significant differences between the two groups with respect to any of the parameters. Both treatment groups demonstrated highly significant improvements in the numbers of pain attacks and their severity; no statistically significant differences between the two groups were demonstrated. Five patients in the mebeverine/dietary advice group reported five concurrent effects and nine patients in the mebeverine/ispaghula group reported 13 concurrent effects. All of the mebeverine/dietary advice group found their treatment acceptable but up to 28% of the mebeverine/ispaghula group found their treatment unpalatable. CONCLUSION Both treatments are effective in the treatment of irritable bowel syndrome in adults. The fixed combination of mebeverine/ispaghula, however, was found to be unpalatable by up to 28% of the patients in that group. There does not, therefore, appear to be any advantage in using fixed combination therapy in this condition.

The aim of this study was to evaluate the efficacy of cimetropium bromide, a new antimuscarinic compound, in relieving symptoms of patients with irritable bowel syndrome over a three month period. Seventy consecutive outpatients were given cimetropium (50 mg tid) or placebo according to a double blind, randomised, parallel groups design. Symptoms were evaluated initially and at monthly intervals up to the end of the study period. One patient receiving placebo withdrew because of treatment failure. Pain score decreased by 40, 66, 85% in the cimetropium group, at the end of the first, second and third months respectively, compared with 26, 32 and 52% reductions among controls (p = 0.0005). At the end of treatment there was a 86% reduction in the number of abdominal pain episodes per day in the cimetropium group compared with 50% in the placebo group (p = 0.001). Constipation and diarrhoea scores decreased by 59 and 49% in the cimetropium treated patients, compared with 37 and 39% in controls, the differences between being not significant. At the end of the study 89% of the patients treated with cimetropium considered themselves as globally improved as opposed to 69% in the placebo group (p = 0.039). The corresponding 95% confidence intervals for the differences between the proportion of improved patients in the two groups were from 11% to 29%. Six patients taking cimetropium complained of slight dry mouth. The results of this study showed that cimetropium bromide is effective in relieving pain in patients with irritable bowel syndrome.

The presently available methods of study of small bowel motility in humans include manometry (or electromyography) which records the temporospatial organization of bowel contractions and determination of intestinal transit time. Investigation of subjects with the irritable bowel syndrome has shown that the small intestine has its part in the motor disturbances. The characteristics of normal motility of the small intestine are well known: the migrating motor complex (MMC) develops during the interdigestive period, typical contractions are seen during phases 2 and 3 of the MMC, the nature and the duration of the motor response to alimentation have been described. In patients with IBS, the production of the MMC is irregular during the day hours; this is most likely due to environmental solicitations and it is recognized that intensive aliess can cause transient interruption of the development of cycles. On the other hand, the MMC develops normally during sleeping hours. Contraction derangements such as non propulsed repeated contractions in the proximal intestine and contractions propulsed too frequently in the small intestine may be found during phase 2. Some of the abnormal contractions coincide with abdominal pain. After meals, the duration of interruption of the MMC is shorter than in the normal subject. Transit time is shortened in patients with diarrhea, lengthened in patients with constipation. Patients with IBS respond excessively to certain stimuli: for instance, the motor response to cholecystokinin is increased compared to the normal subject. Intake of fatty ingesta is followed by the same type of reaction: pain is often associated with abnormal contractions.(ABSTRACT TRUNCATED AT 250 WORDS)

The irritable bowel syndrome is above all a syndrome of intestinal pain. Although the intestinal disorders described in this syndrome have prompted several studies focused on intestinal motility, little has been learned from these studies increasing our knowledge on the pathophysiology of this syndrome. The demonstration of colonic hypermotility or various and slightly significant modification in small intestinal motility do not add much to our knowledge. For one, why are clinical signs such as abdominal pain, bowel movement disorders, and abdominal distension, and most likely other motor disorders, found in numerous normal subjects (14 to 30 percent of the normal population) who do not seed medical advice for intestinal signs which are, one must admit, not very alarming? Are patients who complain of functional digestive tract disorders, constantly seeking medical advice and heavy medication consumers, mentally ill (emotional patients, hypochondriacs, depressive, hysterics), are they just under great stress, or do they indeed have chronic pain pathology? A number of studies show clearly that the last hypothesis is most likely true: patients with the irritable bowel syndrome (i.e. hypersensitive bowel) have a chronic pain pathology because their threshold perception of pain is lower than in the normal population. The threshold tolerance to distension of the pelvic colon is lower in these patients than in asymptomatic patients. The gastric transmural potential is lower in patients complaining of functional intestinal disorders, and it is known that a fragile mucosa is highly sensitive to normally innocuous stimuli.(ABSTRACT TRUNCATED AT 250 WORDS)
