Shear wave elastography to predict oesophageal varices, morbidity and mortality in chronic liver disease.

Introduction: In chronic liver disease (CLD), Fibroscan® (transient elastography) can be a useful "rule-out" test for oesophageal varices, but it is limited by body habitus. Shear wave elastography (SWE) is another non-invasive fibrosis test that is better suited for overweight subjects. We determined SWE's ability to predict oesophageal varices, morbidity and mortality in a predominantly overweight population.

Chromoendoscopy versus standard colonoscopy for detection of nonpolypoid dysplasia in patients with inflammatory bowel disease.

Aim: Inflammatory bowel disease (IBD) is associated with an increased risk of colorectal cancer. Studies show that chromoendoscopy (CE) can increase the detection of dysplasia at surveillance colonoscopy, compared to standard white light endoscopy (WLE). We performed a retrospective cohort study to compare standard WLE to CE with targeted biopsies in detecting nonpolypoid dysplasia in IBD patients undergoing surveillance colonoscopy at a single tertiary centre.
