It includes common and important conditions such as colon polyps and cancer, hepatitis, gastroesophageal reflux , peptic ulcer disease, colitis, gallbladder and biliary tract disease, nutritional problems, Irritable Bowel Syndrome (IBS), and pancreatitis. In essence, all normal activity and disease of the digestive organs is part of the study of Gastroenterology.

  • endoscopic ultrasounds, which examine the upper and lower GI tract, as well as other internal organs
  • colonoscopies, which can detect colon cancer or colon polyps
  • endoscopic retrograde cholangiopancreatography, which identifies stones or tumors in the bile duct area
  • sigmoidoscopy, which evaluates blood loss or pain in the lower large bowel
  • liver biopsy, which assesses inflammation and fibrosis in the liver
