The Ontario Endoscopy Centre data demonstrate that office-based colonoscopies, performed by well-trained physicians using adequate sedation and hospital-grade equipment, result in outcomes at least equal to or better than those of published academic/community hospital practices and are therefore a viable option for the future of screening colonoscopy in Canada.

SUMMARYBackground: Intravenous (IV) proton-pump inhibitor therapy is used in patients who cannot take oral medications or require greater acid suppression. Oral esomeprazole produces greater acid suppression than oral pantoprazole; however, no comparative data exist for oral esomeprazole and IV pantoprazole. Aim: To compare acid suppression (time with pH > 3.0, 4.0, 5.0 and 6.0) produced by standard doses of oral esomeprazole and IV pantoprazole in healthy subjects. Methods: A randomized, two-way crossover study in 30 subjects receiving oral esomeprazole (40 mg o.d.) or IV pantoprazole (40 mg o.d.) for 5 days followed by a 2-week washout period before the second 5-day drug

Background: Self-expandable metal stents (SEMS) can provide temporary relief of acute large bowel obstructions. Placement of SEMS creates the opportunity for semielective 1-stage surgical resections, use of possible adjuvant therapy or palliative relief of malignant obstructions. Our aim was to assess the likelihood of success and possible complication rates of SEMS insertion in a community hospital setting in patients presenting with large bowel obstructions.

Background and Objectives:A Canadian Community Hospital launched a new Endoscopic Ultrasound (EUS) Program in 2011. The aim of this study was to report the accuracy of EUS-fine needle aspiration (EUS-FNA) of solid lesions over time as it pertains to cytotechnologists’ involvement and learning curves.Methods:The electronic medical records of patients that had a EUS from July 2011 to January 2014 were retrospectively reviewed. Only solid lesions with FNA sampling were included in the study. The primary outcome assessed was the accuracy of specimen acquisition for pathological review. The secondary outcome was diagnostic accuracy. Cases were separated by chronological order into thirds for the assessment of learning curves. Cytotechnologists’ involvement was correlated to determine its impact on accuracy.Results:Two hundred and seventy-one EUS-FNA procedures were completed for solid lesions. Cytotechnologists’ involvement resulted in a specimen acquisition accuracy of 82.6%, compared with 68.8% without a cytotechnologist (P = 0.009; 95% confidence interval [CI] 3.2%–25.0%). Diagnostic accuracy was 74.2% with a cytotechnologist while 62.4% without a cytotechnologist (P = 0.038; 95% CI 0.3%–23.7%). The specimen acquisition accuracy increased from 73.2% from the first third of cases to 92.3% for the last third with a cytotechnologist (P = 0.004; 95% CI 6%–33.0%). Without a cytotechnologist, the specimen accuracy was 67.6% for the first third while 57.7% for the last third of cases (P = 0.434; 95% CI − 33.9–14.4%). In the multivariable regression analysis, after adjusting for other predictors, a present cytotechnologist (P = 0.022) and lesion size 21 mm–30 mm (P = 0.039) and >30 mm (P = 0.001) were significantly associated with increased specimen acquisition accuracy. Only a present cytotechnologist (P = 0.046) was significantly associated with increased diagnostic accuracy.Interpretation:Cytotechnologists’ involvement significantly improved the accuracy of specimen acquisition. Although accuracy was impacted by a cytotechnologist learning curve, our results highlight the importance of a cytotechnologist being present for EUS-FNA sampling of solid lesions.
