AIM:To examine the impact of the patient’s birthplace on the prevalence of colonic polyps and histopathological subtypes.METHODS:This is a retrospective audit of the colonoscopy practice of one Gastroenterologist in a tertiaryreferral hospital from 2008 to 2011.Data collected include demography,birthplace,language spoken,details of the colonoscopy including indications,completion rates,complications,results including prevalence and histopathology of polyps.Statistical methods used were binary logistic regression,χ2 and Mann-Whitney U.RESULTS:A total of 623 patients(48%male,67%aged over 50 years)were recruited and categorised according to birthplace:Australia/New Zealand 42%,European 20%,Asian 15%,Middle Eastern/African11%,South American 9%and Pacific Islander 3%.The median age of the cohort was 56.3 years(range:17-91 years),median body mass index 27.3 kg/m2 (range:16-51 kg/m2),25%were smokers,25%had hypercholesterolemia,20%had diabetes mellitus 16%were on aspirin and 7%were on non-steroidal antiinflammatory drugs.A total of 651 colonoscopies were performed for standard indications.The prevalence of polyps varied according to patient’s birthplace:Europe45.1%,Australia and New Zealand 39.5%,Pacific Islands 33.3%,Asia 30.3%,Middle East and Africa26.9%and South America 24.5%(P=0.027,df=6).However,multivariate analysis revealed that birthplace was not an independent predictor of developing polyps,including adenomas and advanced adenomas after correcting for age and male sex.CONCLUSION:Birthplace is not a predictor for developing colorectal neoplasia,including adenomas and advanced adenomas;hence,should not influence the recommendations for colorectal cancer screening.
AIM: To examine the impact of the patient’s birthplace on the prevalence of colonic polyps and histopathological subtypes.
