Colonic fermentation influences lower esophageal sphincter function in gastroesophageal reflux disease.

BACKGROUND & AIMS: Colonic fermentation of carbohydrates is known to influence gastric and esophageal motility in healthy subjects. This study investigated the effects of colonic fermentation induced by oral administration of fructooligosaccharides (FOS) in patients with gastroesophageal reflux disease (GERD). METHODS: In the cross-over design used in the study, 9 patients with symptomatic GERD were administered a low-residue diet (i.e., 10 g fiber/day) during 2, 7-day periods, receiving either 6.6 g of FOS or placebo 3 times daily after meals. Each period was separated by a wash out of at least 3 weeks. On day 7, esophageal motility and pH were recorded in fasting conditions and after a test meal containing 6.6 g of FOS or placebo. Breath hydrogen concentrations (reflecting colonic fermentation) and plasma concentrations of glucagon-like peptide 1 (GLP-1), peptide YY, and cholecystokinin were monitored. RESULTS: Compared with placebo, FOS led to a significant increase in the number of transient lower esophageal sphincter relaxations (TLESRs) and reflux episodes, esophageal acid exposure, and the symptom score for GERD. The integrated plasma response of GLP-1 was significantly higher after FOS than placebo. CONCLUSIONS: Colonic fermentation of indigestible carbohydrates increases the rate of TLESRs, the number of acid reflux episodes, and the symptoms of GERD. Although different mechanisms are likely to be involved, excess release of GLP-1 may account, at least in part, for these effects.

C-reactive protein as an aid in the differentiation of functional and inflammatory bowel disorders.

Eighty-two patients were investigated on their first visit to the outpatient department of St. Mark's Hospital, London, for the assessment of abdominal symptoms. In addition to the clinical examination, a rectal biopsy, routine tests and appropriate special investigations, blood was taken from each patient for the determination of erythrocyte sedimentation rate, C-reactive protein and alpha-1-acid glycoprotein. Nineteen patients were finally diagnosed as having Crohn's disease, twenty-two ulcerative colitis, and forty-one functional bowel disorders. All the patients with Crohn's disease had an elevated erythrocyte sedimentation rate and C-reactive protein level as had 11 (50%) of the patients with ulcerative colitis, but none with functional disorders. All cases of ulcerative colitis could be diagnosed by rectal biopsy. Measurement of alpha-1-acid glycoprotein provided no additional diagnostic information. A combination of rectal biopsy, and measurement of the erythrocyte sedimentation rate and C-reactive protein successfully distinguishes between inflammatory disease of the large and small bowel and functional bowel syndrome.

Irritable bowel syndrome. Practical management.

BACKGROUND: Irritable bowel syndrome (IBS) is a common problem affecting one in six Australians. In any patient complaining of chronic or recurrent abdominal pain, chronic diarrhoea or constipation or bloating, IBS should top the list of possibilities. OBJECTIVE: To outline an approach to the practical management of patients with IBS. DISCUSSION: A positive diagnosis can be made if a few simple questions are asked, and the diagnosis can be confirmed by a small number of tests to exclude structural disease. Improved understanding of the differences in gut function in patients with IBS is likely to result in the development of some exciting new therapies.

[Behavior therapy in gastrointestinal functional disorders].

Almost all functions of the gastrointestinal tract have been shown to be under central nervous control and to respond to environmental factors such as stress. It is, therefore, not surprising that disturbed gastrointestinal functions may be altered through psychological therapy approaches. For motor dysfunctions of the esophagus and functional dyspepsia, there is a lack of behavioral therapy studies, while controlled studies utilizing relaxation techniques, stress management strategies and anxiety treatment have been shown to improve symptoms and prevent recurrence in reflux esophagitis and peptic ulcer disease despite the wide use of effective medication. Most studies have treated patients with symptoms of the irritable bowel syndrome: This approach usually combined conventional medical treatment with psychotherapy. Psychological management usually consisted of relaxation training, stress management and patient information. Additional behavioral modification, e.g. of eating and defecation behavior, is superior to pharmacological and dietary management alone. The role of biofeedback therapy in these patients remains to be clarified in the future. It is, however, therapy of choice in some patients with constipation due to spastic pelvic floor syndrome and in fecal incontinence, if the external anal sphincter is insufficient to maintain continence. There ist a systematic lack of treatment opportunities as compared to the number of patients seeking health care for functional bowel disorders.

Behavioral medicine approaches to gastrointestinal disorders.

Behavioral research in gastroenterology has grown exponentially over the last decade. Controlled studies demonstrate that psychotherapy, stress management, and hypnosis are effective for irritable bowel syndrome; and behavioral treatments are preferred over medical management for some types of fecal incontinence and vomiting. For peptic ulcer disease, interest in behavioral treatments has declined. However, a new syndrome, functional dyspepsia, is now recognized, in which ulcerlike symptoms occur without ulcer and frequently in association with psychological symptoms. For inflammatory bowel disease, stress management training has produced inconsistent outcomes. Newly recognized disorders for which behavioral treatments are needed include constipation associated with inability to relax the pelvic floor muscles during defecation, functional rectal pain (proctalgia), noncardiac chest pain, and aerophagia (excessive air swallowing).

Common functional gastrointestinal disorders: nonulcer dyspepsia and irritable bowel syndrome.

Up to 35% of the world population suffer from functional gastrointestinal disorders (FGD), accounting for about 40% of gastroenterologic and 12% of primary care practice. Society incurs high costs from FGD morbidity in terms of medical workups and absenteeism from work. FGD are characterized by chronic and recurrent symptoms of the gastrointestinal (GI) tract without detectable structural or biochemical abnormalities. In the absence of universal biologic markers, the diagnosis is based on consensus symptom criteria (1). This chapter reviews current knowledge of the pathophysiology and provides a practical approach to patients with functional dyspepsia and irritable bowel syndrome, 2 of the most common functional GI syndromes.

Outcomes of hysterectomy.

Recent randomized trials and prospective cohort studies have provided new information on the health outcomes of hysterectomy for nonmalignant conditions. These studies consistently have demonstrated a marked improvement in symptoms and quality of life during the early years after surgery. The long-term effects of premenopausal hysterectomy on ovarian function have not been established, but existing evidence suggests there is no adverse effect on risk for cardiovascular disease from hysterectomy alone. Epidemiologic studies have indicated that premenopausal hysterectomy with ovarian preservation is associated with a modest decrease in future risk for ovarian cancer and possibly breast cancer. There is no consistent evidence for adverse effects on bowel or bladder function. Hysterectomy does not cause long-term psychiatric morbidity, and psychological status generally improves. Studies of sexual function have shown varying results, with most suggesting improvement or no change in sexual function for the majority of women.
