Peter Legnani, MD

Why did you choose to specialize in gastroenterology?

I found gastroenterology to be a dynamic intersection of multiple fields of study and practice. For example, I found that caring for patients with inflammatory bowel diseases during my residency encompassed immunology, preventative medicine, endoscopic evaluation of inflammation and the potential for endoscopic therapies—and that each patient had their own unique psychosocial context that I had to understand so that I could optimize their treatment and provide education about their disease. Since completing fellowship in 2002, gastroenterology has evolved, rapidly improving endoscopic capabilities for colon cancer screening and imaging the small bowel, understanding new disease, and expanding increasingly safe and effective therapies for inflammation. I enjoy participating in collaborative research and education within gastroenterology—to be able to continue this while caring for patients on a daily basis is why I became a gastroenterologist.

What are your areas of special interest and expertise within gastroenterology?

I am particularly interested in inflammatory bowel diseases, small intestinal disorders, colorectal cancer prevention, and endoscopic evaluation of the small intestine.
