Why Yale Medicine?
  • Our staff includes pathologists specialize in conditions related to the gastrointestinal system.
  • We use molecular and genetic tests in order to make the most accurate diagnosis possible.
  • We provide the highest level of sub-specialized expertise for patients with complex digestive conditions.

When you sit down for a meal, you may not give much thought to what happens after you polish the plate clean. But the human digestive process involves different organs and is quite complicated. Up to 70 million people in the United States, or about 22 percent of the population, suffer from digestive difficulties at any given time, according to the National Institutes of Health. 

For those who need to pinpoint the root cause of their problem, Yale Medicine’s Department of Pathology offers expertise in diagnosing digestive and bowel conditions. “Sometimes a patient’s condition can only be diagnosed by obtaining a tissue sample. We examine tissue from throughout the gastrointestinal tract, including small biopsy samples taken during an endoscopy and surgical resections of tumors, such as colon cancer,” says Marie E. Robert, MD, professor of pathology at Yale School of Medicine.

Clinical Trials

New treatments for many conditions are tested in clinical trials, which ultimately bring lifesaving new drugs and devices to the patients who need them most. By participating in a clinical trial, you may get access to the most advanced treatments for your condition, and help determine their benefits for future patients.
