          Abstract

          Background:

          Treatment of chronic constipation is creating one of the major problems for doctors and patients. Pyridostigmine increases the gastrointestinal motility through the effects on cholinesterase. It seems that this mechanism can reduce chronic constipation. The aim of this study was to compare the effects of pyridostigmine and bisacodyl on chronic constipation.

          Methods:

          This study was conducted on 68 patients who suffered from chronic constipation. Patients were randomly divided into two groups of Pyridostigmine and bisacodyl in which each consisted of 34 patients, respectively. Bristol stool form score, straining defecation, the time of defecation, the number of defecation per week, sense of incomplete evacuation and self-digitation were collected by means of questionnaires and the data were compared.

          Results:

          Sixty-eight patients with the mean age of 68.12±84.49 were studied. The mean difference in the frequency of defecation per week, VAS score, the time to defecation and the Bristol Stool form Scale in pre and post-treatment were 4.33±1.88, 5.96±2.29, 12.30±7.95 min and 2.10±0.95 in pyridostigmine group and 2.96±1.81, 4.06±2.22, 6.67±5.23 min and 1.41±0.84 in bisacodyl group, respectively. The significant difference was observed in both pyridostigmine and bisacodyl groups (P=0.005, P=0.002, P=0.002 and P=0.005, respectively). 60% and 32.3 of patients in pyridostigmine and bisacodyl groups recovered from self-digitations, respectively. In pyridostigmine and bisacodyl groups, 66.7% and 32.3 of them had improvement in the sense of incomplete defecation, respectively.

          Conclusion:

          Pyridostigmine and bisacodyl significantly improved the symptoms of chronic constipation similarly.

          U.S. householder survey of functional gastrointestinal disorders. Prevalence, sociodemography, and health impact.

          Our objective was to obtain national data of the estimated prevalence, sociodemographic relationships, and health impact of persons with functional gastrointestinal disorders. We surveyed a stratified probability random sample of U.S. householders selected from a data base of a national market firm (National Family Opinion, Inc.). Questions were asked about bowel symptoms, sociodemographic associations, work absenteeism, and physician visits. The sampling frame was constructed to be demographically similar to the U.S. householder population based on geographic region, age of householder, population density, household income, and household size. Of 8250 mailings, 5430 were returned suitable for analysis (66% response). The survey assessed the prevalence of 20 functional gastrointestinal syndromes based on fulfillment of multinational diagnostic (Rome) criteria. Additional variables studied included: demographic status, work absenteeism, health care use, employment status, family income, geographic area of residence, population density, and number of persons in household. For this sample, 69% reported having at least one of 20 functional gastrointestinal syndromes in the previous three months. The symptoms were attributed to four major anatomic regions: esophageal (42%), gastroduodenal (26%), bowel (44%), and anorectal (26%), with considerable overlap. Females reported greater frequencies of globus, functional dysphagia, irritable bowel syndrome, functional constipation, functional abdominal pain, functional biliary pain and dyschezia; males reported greater frequencies of aerophagia and functional bloating. Symptom reporting, except for incontinence, declines with age, and low income is associated with greater symptom reporting. The rate of work/school absenteeism and physician visits is increased for those having a functional gastrointestinal disorder. Furthermore, the greatest rates are associated with those having gross fecal incontinence and certain more painful functional gastrointestinal disorders such as chronic abdominal pain, biliary pain, functional dyspepsia and IBS. Preliminary information on the prevalence, socio-demographic features and health impact is provided for persons who fulfill diagnostic criteria for functional gastrointestinal disorders.

              Review article: epidemiology and quality of life in functional gastrointestinal disorders.

              The epidemiology and health-related quality of life associated with functional gastrointestinal disorders are reviewed, with particular emphasis on irritable bowel syndrome and functional dyspepsia. The literature supports the significant world-wide prevalence of functional gastrointestinal disorders, including irritable bowel syndrome (IBS), functional dyspepsia and chronic constipation. An increased female prevalence has been demonstrated in most studies in patients with IBS and chronic constipation, but not functional dyspepsia. The female to male ratio appears to be greater in the health care-seeking population than in community populations. However, some differences in the reported general prevalence and gender-related prevalence of functional gastrointestinal disorders may be due to cultural factors and study methodology. A significant health care burden is associated with IBS, with increased out-patient services, abdominal and pelvic surgeries, and gastrointestinal- and non-gastrointestinal-related physician visits and health care costs. Health-related quality of life is impacted significantly in patients with functional gastrointestinal disorders, such as functional dyspepsia and IBS, compared with the general healthy population, as well as patients with other chronic medical conditions, such as gastro-oesophageal reflux disease and asthma. Impaired health-related quality of life has been demonstrated, in particular, in patients with moderate to severe disease seen in referral settings. The health-related quality of life appears to improve in treatment responders, or correlates with symptom improvement, with at least some treatment modalities studied in functional gastrointestinal disorders, but further studies are needed. Predictors of health-related quality of life in patients with functional gastrointestinal disorders include psychosocial factors, such as early adverse life events, and symptoms related to visceral perception, e.g. pain and chronic stress. The presence of extra-intestinal symptoms appears to have a major if not greater impact on health care visits, excess health care costs and health-related quality of life in patients with functional gastrointestinal disorders.
