Gastroenterology
The Department of Gastroenterology specializes in the treatment of disorders of the esophagus, stomach, intestines, liver, gallbladder, pancreas, and other organs of the digestive system.
Medical services
Approximately 90 specialists work together in this department to treat diseases, mainly cancers, of the esophagus, stomach, large intestine, liver, gallbladder, bile duct and pancreas; and other particularly intractable diseases such as hepatitis, pancreatitis and inflammatory bowel disease.
Diagnosis and treatment policy
“Patient-oriented, non-invasive treatment” is our motto. Aiming to achieve maximum outcomes with minimally-invasive approaches, the department adopts a team approach to care for patients with refractory cancer and other intractable diseases. Efforts are focused on treating not only the disease but the patient as a whole.

Outpatients
- Abdominal ultrasound examination : gallbladder, pancreas, kidney, spleen, lymph node
- Upper endoscopy (gastroscopy) : esophagus, stomach, duodenum
- Lower endoscopy (colonoscope) : colon and rectum
