When studying the gastrointestinal system, be sure to understand the
normal embryology, anatomy, and physiology and how it is affected in
the various pathologic diseases. Study not only what a disease entails,
but also its specific findings, so that you can differentiate between two
similar diseases. For example, what specifically makes ulcerative colitis
different than Crohn disease? Also, it is important to understand bile
metabolism and which lab values increase or decrease depending on the
disease process. Be comfortable with basic interpretation of abdominal
x-rays, CT scans, and endoscopic images.
