Medical services and specialties

Malignant tumors of the gastrointestinal tract such as stomach cancer, esophageal cancer, colorectal cancer and the like are frequent among cancers, it is very important to detect these cancers at an early stage and provide appropriate treatment. Patients who have symptoms related to the gastrointestinal tract or patients with gastrointestinal tract abnormality as indicated by barium examination or fecal occult blood tests, etc., are examined in detail by experienced endoscopists using the latest endoscopic devices.

We also make diagnosis and treatment of obstructive jaundice, gallbladder cancer, biliary cancer, and pancreatic cancer. Especially diagnosis and treatment of biliary tract and pancreas using endoscope or ultrasonic endoscope are highly evaluated internationally, and we actively engage in technical guidance and acceptance of operation observing for visitors. Among them, ERCP for postoperative reconstructed intestinal tract such as EUS-FNA using ultrasonic endoscope or Roux-en-Y case using balloon endoscope is evaluated as one of the world’s leading facilities.
