Improving treatment of patients with inflammatory bowel diseases (IBD)

  • Application of microarray technology to predict the outcome of IBD as well as a patient's response to therapies, such as infliximab, adalimumab, and vedolizumab. 

Small bowel endoscopy 

  • Double-balloon endoscopy is a relatively new technology that my team is assessing for the management of patients with Crohn's disease of the small bowel. 
  • Imaging of the entire intestinal tract provides insight into how the individual is responding to therapy and can inform treatment modifications.
