The characteristics and the prevalence of functional bowel disorders in the general French population are unknown. Based on an epidemiological inquiry in a random population of 1,200 persons who were not seeking care, residents in our country we established: the prevalence of symptoms suggestive of functional bowel disorders; the epidemiological differences between symptomatic subgroups which included abdominal pain with or without bowel dysfunction, diarrhea and constipation. The amount of cases and the prevalence in each subgroup were: abdominal pain, 165, 13.8 p. 100, painless constipation, 75, 6.3 p. 100, diarrhea, 10, 0.8 p. 100. As a whole, functional bowel disorders occurred in 20 p. 100 of our population. The "irritable bowel syndrome" group defined as abdominal pain and/or diarrhea differ from normal subjects by the following higher frequency of age under 50, subjects in active duty, antecedents of diverticulosis, influence of stress on symptoms, nausea, vomiting, migraines, pyrosis and number of visits to a doctor. However neither the sex-ratio nor professional occupation were relevant. The constipation group differed from normal because of the higher frequency of female sex, antecedents of hiatus hernia, use of laxatives but not because of age nor by the number of associated symptoms. In conclusion, functional bowel disorders occurred in 20 p. 100 of our population; two subgroups were clearly different from an epidemiological point of view, the irritable bowel syndrome (13 p. 100) and constipation (7 p. 100); therefore these two groups deserve a specific physiopathological, psychological and therapeutic approach.

During a 2 year period, 83 patients with gastric motility problems were evaluated using radionuclide imaging. The patients presented with epigastric distress, postprandial fullness, pain, nausea, vomiting, and diarrhea; signs and symptoms suggestive of either gastroparesis or gastric outlet obstruction. Upper gastrointestinal series or endoscopy, or both, demonstrated no mechanical obstruction. After oral administration of a 300 g meal labeled with 600 muCi of technetium-99m sulfur colloid, a gastric emptying study consisting of serial images and data acquisition was performed. Of the patients studied, 52 had had peptic ulcer surgery, 17 were suspected of having gastroesophageal reflux, 8 were diabetic and suspected of having visceral enteropathy, and 6 had a history of irritable bowel syndrome. The normal mean gastric half emptying time was 77 +/- 16 minutes. Of the patients who had had gastric surgery, 90.4 percent had abnormal emptying: 69.2 percent had delayed gastric emptying and 21.2 percent had rapid gastric emptying time; 9.6 percent had normal emptying time. Of the gastroesophageal reflux group, all but two had normal gastric emptying time; 65 percent demonstrated gastroesophageal reflux within 15 minutes. Two of the patients with irritable bowel syndrome had prolonged emptying; the rest had normal emptying. All diabetic patients with gastroparesis had prolonged gastric emptying time, and all responded favorably to metoclopramide. Of the patients who previously had peptic ulcer surgery and had prolonged emptying time, 72 percent also responded favorably to metoclopramide. We conclude that radionuclide gastric imaging is a useful diagnostic test for the measurement of gastric emptying in patients with a variety of gastrointestinal motility disorders and may be helpful in assessing medical therapy and selecting those who may be candidates for surgery.

In 73 patients the occurrence of dyspeptic symptoms were correlated with the presence of a normal duodenal loop (29 patients) and an abnormal duodenal loop (44 patients). An abnormal duodenal loop was associated with a significantly higher incidence of symptoms provoked by meals, vomiting, regurgitation, heartburn, and the irritable bowel syndrome.

This study reviews 71 patients who presented between 1968 and 1988 with recurrent, self-limited episodes of nausea and vomiting separated by symptom-free intervals and were diagnosed with cyclic vomiting syndrome (CVS). The length and symptomatology of episodes tended to be stereotyped and characteristic for each patient over time. The disorder may persist from months to decades. There is a coincident relationship between CVS, migraine, and irritable bowel syndrome. The differential diagnosis includes many diseases which may mimic CVS. Management involves a responsive, collaborative doctor-patient relationship, sensitivity to stresses caused by the illness and to feelings and attitudes that may predispose to attacks, use of antiemetic agents to abort or shorten attacks, treatment of complications, and use of prophylactic agents in patients whose episodes are of sufficient frequency and severity to warrant their trial.

The effects of octreotide on six normal subjects and five patients with scleroderma were investigated. Changes in intestinal motility and in plasma motilin were examined after a single injection of octreotide. Octreotide stimulated intense intestinal motor activity in normal subjects. Motility patterns in the scleroderma patients were chaotic and non-propagative, but, after octreotide was given, became well coordinated, aborally directed, and nearly as intense as in normal volunteers. Clinical responses and changes in breath hydrogen were also evaluated in the five scleroderma patients who had further treatment with octreotide at a dose of 50 micrograms/day subcutaneously for three weeks. A reduction in symptoms of abdominal pain, nausea, vomiting, and bloating was seen. Additionally, there was an improvement in bacterial overgrowth as objectively measured by breath hydrogen testing. The effects of octreotide (100 micrograms/day subcutaneously) on the perception of rectal distension were investigated in a double blind, placebo controlled study in healthy volunteers. Octreotide was shown to reduce the perception of rectal distension without affecting motor pathways or local rectal reflexes. This enhanced tolerance to volume distension seems to result from inhibition of sensory afferent pathways as shown by electroencephalographic studies showing diminished evoked spinal and cortical potentials after octreotide. In irritable bowel syndrome patients with rectal urgency, octreotide reduces rectal pressures and perception after rectal distension to near normal values.

Dyspepsia is a vague term for the nonspecific symptoms of upper abdominal discomfort, prolonged postprandial fullness or early satiety, nausea, vomiting, and upper abdominal bloating. Many common and accepted diseases and disorders such as gastroesophageal reflux and irritable bowel syndrome cause dyspepsia symptoms; these disorders should be identified and treated. However, many patients with dyspepsia symptoms have normal radiographic and endoscopic evaluations; in these patients, neuromuscular of functional disorders of the stomach ranging from gastric dysrhythmias to gastroparesis may be the cause of dyspepsia symptoms. A practical approach to the evaluation and treatment of dyspepsia symptoms attributed to gastric neuromuscular dysfunction of unknown origin is described.

The relationship between characteristics of irritable bowel syndrome (IBS) and eating disorders (ED) was investigated in a clinical sample of 43 female and 17 male IBS patients who completed the Eating Disorder Inventory (EDI). A diagnosis of IBS was generally unrelated to the Body Dissatisfaction, Perfectionism, and Ineffectiveness subscales of the EDI, but symptom severity was correlated with Perfectionism and Ineffectiveness. Severe bouts of vomiting were significantly associated with desires for lower body weight and reported binge-purge behaviors and cognitions measured by the Bulimia subscale of the EDI. Results suggest the need for a more comprehensive understanding of both types of illness as well as a possible framework for future empirical work.

While many definitions exist, dyspepsia is best considered a symptom complex (not a diagnosis) thought to arise in the upper gastrointestinal tract, unrelated to defecation. The symptom complex includes: upper abdominal/epigastric pain or discomfort, postprandial fullness, bloating, belching, early satiety, anorexia, nausea, retching, vomiting, heartburn and regurgitation. Patients with typical gastroesophageal reflux, biliary colic and irritable bowel syndrome should not be considered to have dyspepsia. After investigations, if a cause of dyspepsia is found, this is 'organic or structural' dyspepsia. If no structural cause is found, this is best called 'functional dyspepsia', subclassified into a) ulcer-like b) dysmotility-like c) reflux-like and d) unspecified dyspepsia. This symptom guided classification should be shifted to the first presentation with uninvestigated dyspepsia, prior to any investigations, to define a clinically useful guide to patient care. As there is considerable symptom overlap, it may be useful to combine together the ulcer and reflux-like groups into an acid-related dyspepsia group. In 1998, another approach would be to screen dyspeptic patients with an H. pylori test and classify them as H. pylori positive and negative dyspepsia.

Motility disorders are very common in childhood, causing a number of gastrointestinal symptoms: recurrent vomiting, abdominal pain and distension, constipation and obstipation, and loose stools. The disorders result from disturbances of gut motor control mechanisms caused by either intrinsic disease of nerve and muscle, central nervous system dysfunction or perturbation of the humoral environment in which they operate. Intrinsic gut motor disease and central nervous system disorder are most usually congenital in origin, and alterations of the humoral environment acquired. Irritable bowel syndrome occurs in children as well as adults and is multifactorial in origin, with an interplay of psychogenic and organic disorders.

The evidence supporting a role of abnormal motor function in irritable bowel syndrome (IBS) is reviewed. Symptoms commonly present in IBS patients, such as vomiting, diarrhea, constipation or incomplete rectal evacuation, indicate that a motor disorder is implicit as either a primary or secondary disturbance. Physiological studies implicate a disturbance of transit through the small bowel and proximal colon, and abnormal motor responses of the rectum to distention in IBS patients. Intestinal contractions (physiological or 'abnormal') are associated with the sensation of pain, suggesting that these contractions are interactions between abnormal motor and sensory functions in IBS. Therapies aimed at correcting abnormal transit or antispasmodics are the main pharmacological approaches to the relief of IBS, and, although the latter are not always effective in the long term response to treatment, they support the role of dysmotility in IBS. Most novel therapies under trial probably modulate both sensory and motor functions, and are discussed briefly. In summary, the weight of clinical, physiological and pharmacological evidence supports a role of abnormal motility in IBS.
