Gastroenterologists at Doctors Hospital specialize in the prevention, diagnosis and treatment of disorders of the digestive tract and liver. Gastroenterologists diagnose and treat disorders of the esophagus, stomach, small intestine, colon and rectum, pancreas, gallbladder, bile ducts and liver.


Our Services
Doctors Hospital resources include the latest in endoscopic equipment and techniques. Using these minimally invasive procedures, doctors insert tubes through the mouth, or rectum to examine and treat problems of the digestive tract.
Endoscopic examinations allow physicians to diagnose and treat a variety of gastrointestinal disorders, including abdominal pain, vomiting, and bleeding from the intestinal tract. In addition, benign (non-cancerous) growths of the colon i.e. polyps, which can lead to colon cancer, may be detected and removed with the help of an endoscope. Endoscopes are flexible tubes that can be passed through the mouth or rectum. They allow physicians to see and examine the surfaces of the esophagus (food pipe), stomach, intestine, and colon.


The Gastroenterology Department at Doctors Hospital utilizes state-of-the art endoscopic equipment in order to take stones out of bile duct, pancreatic ducts, as well as place stents in order to open blocked ducts. Our doctors can also place feeding tubes in the stomach as PEG tubes. In bleeding cases, our doctors apply hemoclips, cauterize the bleeding ulcers and apply band ligation of varices. Our gastroenterologists are also skilled at taking biopsies of growth to diagnose cancer. Furthermore, the department utilizes endoscopic ultrasounds to help diagnose tumors, cancer, and tuberculosis of deeper areas of the esophagus, stomach, rectum, lymph nodes, and pancreas by fine needle aspiration and core biopsies.

Hepatitis B and C are treated with all the modern drugs.

Capsule Endoscopy Service

Doctors Hospital now offers Capsule Endoscopy service, by which a small capsule is swallowed that can take images of the entire small bowel. The small intestine is an area that is usually difficult to access by upper endoscopy and colonoscopy. Capsule endoscopy is useful when disease is suspected in the small intestine, and can sometimes diagnose sources of occult bleeding [blood visible only microscopically] or causes of abdominal pain such as Crohn’s disease, peptic ulcers, typhoid ulcers, and tuberculosis.

Small Bowel Enteroscopy

Doctors Hospital also offers Small Bowel Enteroscopy service. With small bowel enteroscopy the entire small bowel is examined, biopsies are taken for diagnosis and treatment is rendered to stop bleeding. Enteroscopes are much longer than standard gastroscopes and can visualize the small bowel, averaging 4–6 meters in an adult. This technique is also referred to as single balloon enteroscopy.
