Advanced Endoscopy

The therapeutic endoscopy group in Calgary is engaged in a number of clinical research projects. In addition to leading and participating in a number of clinical trials, we are capitalizing on existing administrative data infrastructure to bolster research output and establish a culture of academic productivity in therapeutic endoscopy.

 Active studies:

  • Evaluating the need for a follow-up ERCP in the management of post-cholecystectomy biliary leaks
  • Evaluating time trends and predictors of mortality in cholangitis and pancreatitis using the National Inpatient Sample (NIS) in the United States
  • Evaluating EUS utilization, disparities of EUS service provision and complications of EUS in Alberta and Ontario
  • Evaluating the use of optical enhancement for identifying colorectal neoplasia: A randomized controlled trial (RCT) of optical enhancement (i-scan) compared to standard high definition optical colonoscopy for detecting adenomas in patients at increased risk of colorectal cancer
  • Evaluating the utility of capsule endoscopy in obscure GI bleeding: RCTs of capsule endoscopy compared to traditional diagnostic modalities in patients with obscure gastrointestinal bleeding
  • Evaluating clinical outcomes following double balloon endoscopy
  • Calgary is a recruitment site for a multicenter RCT comparing fully covered metal and plastic biliary stents for benign biliary strictures
  • Evaluating the clinical and resource benefits of tandem EUS and ERCP for moderate probability choledocholithiasis
  • Evaluating the role of rectal endoscopic ultrasound in the assessment of rectal mucosal disease activity in inflammatory bowel disease (collaboration)
  • Participating in a registry of clinical use of Wallflex (Boston Scientific) biliary self-expanding metal stents
