Continuous quality improvement of colorectal cancer screening

引用

World Journal of Gastrointestinal Pharmacology and Therapeutics 2013年第1期4卷 1-3页

Quality assurance is a key issue in colorectal cancer screening, because effective screening is able to improve primary prevention of the cancer. The quality measure may be described in terms:how well the screening test tells who truly has a disease (sensitivity) and who truly does not have a disease (specificity). This paper raises concerns about identification of the optimal screening test for colorectal cancer. Colonoscopy vs flexible sigmoidoscopy in colorectal cancer screening has been a source of ongoing debate. A multicentre randomised controlled trial comparing flexible sigmoidoscopy with usual care showed that flexible sigmoidoscopy screening is able to diminish the incidence of distal and proximal colorectal cancer, and also mortality related to the distal colorectal cancer. However, colonoscopy provides a more complete examination and remains the more sensitive exam than flexible sigmoidoscopy. Moreover, colonoscopy with polypectomy significantly reduces colorectal cancer incidence and colorectal cancer-related mortality in the general population. The article considers the relative merits of both methods and stresses an ethical aspect of patient's involvement in decision-making. Patients should be informed not only about tests tolerability and risk of endoscopy complications, but also that different screening tests for bowel cancer have different strength to exclude colonic cancer and polyps. The authorities calculate effectiveness and costs of the screening tests, but patients may not be interested in statistics regarding flexible sigmoidoscopy screening and from an ethical point of view, they have the right to chose colonoscopy, which is able to exclude a cancer and precancerous lesions in the whole large bowel.

Rectal bleeding in adults over 20 years: Endoscopic investigations and results in current hospital practices in Yaoundé, Cameroon

Open Journal of Gastroenterology 2013年第6期3卷 298-302页

Introduction: In order to identify the modes of investigation and the results of the assessment of rectal bleeding in the Cameroonian adult, we retrospectively analysed the records of 287 patients aged above 20 years diagnosed with rectal bleeding with the aim to know the prescription patterns according to age, the diagnostic performance of tests and the results. Methodology: Between the 1st of January 2009 and the 30th of June 2010, we examined patients at the University Teaching Hospital and the “La Cathédrale” Medical Centre in Yaounde. Age, sex, endoscopic tests and results were evaluated. Results: 287 protocols met our selection criteria, sex ratio (M/F) 2.4/1, median age 46 years interquartile range [36, 55]. Normal tests were 57 (19.2%). Main lesions: haemorrhoids (42.4% CI95 36.7 -48.3), colorectal cancer (10.8% CI95 7.5 -14.9), anal fissure (8.8% CI95 5.8 -12.6) and colorectal polyps (8.4% CI95 5.5 -12.2). The prevalence of significant lesions (polyps and cancer) recorded 7% for those under age 40. 20.5% in those were between 40?-50 years, and 28.9% for those over 50 years. For anoscopies, 44.4% were under 40 years, 39.3% of cases of sigmoidoscopy affected those between 40 -50 years and colonoscopy affected 54% of those over 50 years. For the diagnostic yield, 26.2% had a significant lesion for flexible sigmoidoscopy and only 16.7% and 1.6% for colonoscopy and anoscopy respectively. Conclusion: The study shows that anoscopy and sigmoidoscopy are the main initial tests conducted in Cameroon in the assessment of rectal bleeding in adults of less than 50 years and they are quite sufficient. Haemorrhoids and colorectal cancer are the main pathologies.

Role of virtual reality simulation in endoscopy training

引用

World Journal of Gastrointestinal Endoscopy 2015年第18期7卷 1287-1294页

作者： Louis Harpham--Lockyer Faidon--Marios Laskaratos Pasquale Berlingieri Owen Epstein Centre for Gastroenterology Royal Free London NHS Foundation Trust Academic Centre for Medical Education University College London Centre for Screen-Based Simulation Royal Free London NHS Foundation Trust

Recent advancements in virtual reality graphics and models have allowed virtual reality simulators to be incorporated into a variety of endoscopic training programmes. Use of virtual reality simulators in training programmes is thought to improve skill acquisition amongst trainees which is reflected in improved patient comfort and safety. Several studies have already been carried out to ascertain the impact that usage of virtual reality simulators may have upon trainee learning curves and how this may translate to patient comfort. This article reviews the available literature in this area of medical education which is particularly relevant to all parties involved in endoscopy training and curriculum development. Assessment of the available evidence for an optimal exposure time with virtual reality simula-tors and the long-term benefits of their use are also discussed.
