Research Summary

I am interested in clinical studies that examine the value of interventions for detecting and treating GI diseases. We have a large clinical practice and some of our present clinical studies include the value of surveillance of Barrett's esophagus, screening intervals for colo-rectal cancer surveillance, interventions to prevent post-ERCP pancreatitis and use of confocal microscopy in management of pre-malignant mucosal GI diseases.

Specialized Terms: Value of interventions for detecting and treating GI diseases
