The Gastroenterology Division at Houston Methodist Hospital is ranked No. 12 by U.S.News & World Report for 2013-2014.

The Gastroenterology Division at Houston Methodist Hospital is a multidisciplinary team of expert physicians, exceptional nurses and other specially trained health care professionals who work together to diagnose and treat diseases of the esophagus, stomach, liver, pancreas, biliary tree, small intestine and colon with leading-edge technology and research. This collaboration between experts in gastroenterology, surgery, oncology and radiology ensures that patients receive compassionate and innovative care at Houston Methodist.

    Esophageal Diseases

    Pancreas and Biliary Diseases
  • Pancreatic diseases
  • Gallbladder and bile duct diseases
    Liver Diseases
  • Acute and chronic liver diseases
    • Hepatitis
    • Cirrhosis
  • Transplant evaluation
    Intestinal Disorders
  • Gastrointestinal motility disorders
  • Inflammatory bowel diseases
    • Crohn's disease

The Gastroenterology Division works closely with the Methodist Institute for Technology, Innovation, and Education (MITIESM) to educate physicians-in-training in performing advanced procedures such as radiofrequency ablation for Barrett's esophagus. Their unique partnership fosters the development of innovative technological treatments for all gastrointestinal (GI) diseases while promoting academic strength through exposure to the latest clinical techniques.

Experts at Houston Methodist use sophisticated, state-of-the-art technologies to image as well as evaluate the physiology of the gastrointestinal tract, assisting in diagnosis and treatment.

  • High-definition upper and lower endoscopy
  • Endoscopic mucosal resection
  • Endoscopic ultrasound
  • Capsule endoscopy

  • Endoscopic retrograde cholangiopancreatography (ERCP)
  • High-resolution esophageal manometry
  • Push and balloon enteroscopy
  • Radiofrequency ablation
  • High-resolution anorectal manometry

While the Gastroenterology Division also offers care for common GI ailments, its physicians also work in concert with the Methodist Cancer Center, Methodist Transplant Center and Methodist Center for Liver Disease and Transplantation to stage cancers of the colon, esophagus, pancreas and stomach, as well as treat early cancer with techniques such as radiofrequency ablation. The Reflux Center & GI Physiology Lab employs physiological studies such as Impedance-pH monitoring to assess esophageal and intestinal function to aid in management of the patient, often before surgery.
