Colonoscopy skills improvement training improves patient comfort during colonoscopy.

INTRODUCTION: We aimed to assess the effect of Colonoscopy Skills Improvement (CSI) training on patient comfort and sedation-related complications during colonoscopy. METHODS: This retrospective cohort study was performed on 19 endoscopists practicing in a Canadian tertiary care center who completed CSI training between October 2014 and May 2016. Data from 50 procedures immediately prior to, immediately after, and eight months following CSI training were included for each endoscopist. The primary outcome variable was intraprocedural comfort, and secondary outcomes included intraprocedural hypotension and hypoxia. Data were extracted from an electronic medical record and analyzed using SPSS version 20.0. Univariate analysis and stepwise multivariable logistic regression were performed to determine if there was an association between patient comfort and CSI training. Predictors of these outcomes including patient age, gender, sedation use and dosing, procedure completion, quality of bowel preparation, endoscopist experience, and specialty were included in the analysis. RESULTS: 2533 colonoscopies were included in the study. The mean dose of sedatives was reduced immediately following CSI training and at 8 months for both Fentanyl (75.4 mcg v. 67.8 mcg v. 65.9 mcg, p < 0.001) and Midazolam (2.57 mg v. 2.27 mg v. 2.19 mg, p < 0.001). The percentage of patients deemed to have a comfortable exam improved following endoscopist participation in CSI training and remained improved at 8 months (55.1% v. 70.2% v. 69.8%, p < 0.001). No significant change in rates of intraprocedural hypoxia or hypotension were noted following CSI training. CONCLUSION: CSI training is associated with improved patient comfort and reduced sedation requirements during colonoscopy.

Quality of life measurement in gastrointestinal and liver disorders.

Modern medicine has had a considerable impact on mortality rates for serious illness. Many chronic diseases which have previously been associated with an increased mortality now have survival rates approaching those of the background population. However, chronic diseases such as cancer, chronic pain syndromes, and chronic inflammatory conditions impose a considerable burden on families, the health care system, and society. Health related quality of life (HRQOL) is a concept that has developed from the need to estimate the impact of such chronic diseases. HRQOL measurement is a conceptual framework which attempts to predict daily function and well being based on subjective attitudes and experiences of physical, social, and emotional health. It has been evaluated predominantly from the patient's viewpoint as proxy respondents appear to underestimate the full effect of chronic illness on functional status. Measuring HRQOL in clinical research is most frequently undertaken using multi-item questionnaires to estimate daily function. Factors which affect HRQOL can be broadly classed as disease related and disease independent. The use of different assessment techniques permits comparisons between and within disorders. Generic and disease specific instruments used together enhance the ability to direct treatment for individuals and patient populations. Psychometrically sound questionnaires must be used. However, the type of instrument and research methods adopted depend on the question of interest. We have attempted to catalogue and critically assess the disease specific instruments used in the assessment of chronic gastrointestinal disease.

Anti-tuberculous therapy for maintaining remission of Crohn's disease.

OBJECTIVES: To evaluate the effects of anti-tuberculous therapy for the maintenance of remission in patients with Crohn's disease. SEARCH STRATEGY: We searched the Inflammatory Bowel Disease Trials Register, the Cochrane Controlled Trials Register and MEDLINE from 1966 to 1998 (supplemented by a manual search of Index Medicus from 1966 to 1994). We also searched for abstracts in Gut, Gastroenterology, and The American Journal of Gastroenterology from 1990 to 1996. Date of most recent search: August 1998. SELECTION CRITERIA: Randomized trials of anti-tuberculous therapy in patients with Crohn's disease. DATA COLLECTION AND ANALYSIS: Data on the number of patients maintaining remission for each treatment group were abstracted. These data were pooled to yield Mantel-Haenszel odds ratios and numbers needed to treat for maintenance of remission in treated versus control groups. MAIN RESULTS: A total of seven randomized trials which included 355 patients were identified. Two trials used anti-tuberculous therapy (clofazimine or clofazimine, rafmpin, ethambutol, and dapsone) in combination with corticosteroids to induce remission. Maintenance therapy consisted of the anti-tuberculous agents without corticosteroids. Control patients received corticosteroids to induce remission but no anti-tuberculous therapy. The analysis of all seven trials yielded an odds ratio for maintenance of remission of 1.36 (95% CI 0.87-2. 13). Removing the two studies that were published as abstracts did not significantly affect this result: the pooled odds ratio was 1.14 (95% CI 0.71-1.83). The two trials reported as abstracts were excluded from subgroup analyses because they did not include any information on adjunct therapy. Subgroup analysis of the two trials which used steroids to induce remission yielded an odds ratio for maintenance of remission of 3.37 (95% CI 1.38-8.24). The number needed to treat was three. However, these two trials included only 89 patients, and the results should be interpreted with caution. The remaining three trials compared the combination of anti-tuberculous therapy and 'standard therapy' with 'standard therapy alone'. The pooled odds ratio was 0.70 (95% CI 0.39-1.25). REVIEWER'S CONCLUSIONS: Anti-tuberculous therapy may be effective in maintaining remission in patients with Crohn's disease when remission has been induced with corticosteroids combined with anti-tuberculous therapy. However, the results which support this conclusion come from a subgroup of only two trials with small numbers of patients and should be interpreted with caution. Use of this therapy cannot be recommended on the basis of this evidence.

A meta-analysis of antimycobacterial therapy for Crohn's disease.

OBJECTIVE: Various therapies have been studied for the treatment of Crohn's disease, including antimycobacterial therapy. Meta-analysis was used to evaluate the effect of antimycobacterial therapy in patients with Crohn's disease. METHODS: Randomized, controlled trials comparing antimycobacterial therapy with placebo were identified. Key outcome data were abstracted and the results were pooled to yield odds ratios for maintenance of remission in treated versus control groups. RESULTS: A total of eight randomized trials were identified. Six trials were fully published and were included in the primary analysis. Two trials used antimycobacterial therapy in combination with corticosteroids to induce remission in patients with active Crohn's disease, followed by maintenance therapy with antimycobacterial agents. In these trials, control patients received corticosteroids to induce remission but no antimycobacterial therapy. Pooling of these trials yielded an odds ratio of maintenance of remission in treatment versus control of 3.37 (95% confidence interval [CI], 1.38-8.24) in favor of antimycobacterial therapy. The remaining four trials used antimycobacterial therapy combined with standard therapy in patients with Crohn's disease. In these trials, control patients received standard therapy alone. Pooling of these trials yielded an odds ratio of maintenance of remission in treatment versus control of 0.69 (95% CI, 0.39-1.21) in favor of standard therapy. CONCLUSIONS: These results suggest that antimycobacterial therapy is effective in maintaining remission in patients with Crohn's disease after a course of corticosteroids combined with antimycobacterial therapy to induce remission. Treatment of Crohn's disease with antimycobacterial therapy does not seem to be effective without a course of corticosteroids to induce remission. Because of the small number of studies included in this meta-analysis, the results should be interpreted with caution.

Putative inflammatory and immunological mechanisms in functional bowel disorders.

The observations that irritable bowel syndrome (IBS) may be precipitated by an acute enteric infection, or occurs commonly in patients in remission from inflammatory bowel disease (IBD) has prompted consideration of inflammation as a putative basis for symptom generation in IBS. In this regard, IBS may follow a pattern of pathogenesis that is similar to asthma--which was once considered a psychosomatic disease. This review examines the basic scientific evidence of a functional interface between the immune and sensory-motor systems of the gut and discusses how this may be relevant to a subgroup of IBS patients. In addition, review will examine the implications of this for the diagnosis and treatment of IBS.

Primary biliary cirrhosis and type II autoimmune polyglandular syndrome.

A 45-year-old female was diagnosed with Hashimoto's thyroiditis in 1976 and Addison's disease in 1979. At that time, her antimitochondrial antibody (AMA) level was elevated at 1:32. She subsequently developed premature ovarian failure and type I diabetes mellitus. In 1996, she became jaundiced with a cholestatic enzyme pattern. AMA was positive at a titre of 1:256. A liver biopsy confirmed the diagnosis of primary biliary cirrhosis (PBC). She underwent a liver transplantation in January 1998. This is the first report of PBC in association with type II autoimmune polyglandular syndrome. The association of PBC with other organ-specific autoimmune diseases supports an immune-mediated pathogenesis and may have implications in further studies of PBC.

Antibiotics.

Antibiotics may be a helpful addition to your therapy for IBD. Although it sounds as if there are a number of side effects, most patients do well, without any problems. If you develop new or worsening symptoms, or if you have other concerns, feel free to discuss them with your physician.
