Dr. Caldwell performs procedures of Colonoscopy, Upper Endoscopy, Liver biopsy and Fibroscan.  The latter is a safe and noninvasive FDA-approved device using a technique of transient elastography to measure the “stiffness” or fibrosis of the liver, which in many instances can substitute for a liver biopsy in the measurement of fibrosis.    Patients with general gastrointestinal or liver conditions can make an appointment to be seen in either the New Haven or Guilford CGC offices, where Dr. Caldwell practices 5 days per week.
