We treat patients with any of the gastroenterological diseases.
In particular, we accept patients with alimentary malignant tumors and for organ transplantation.
Alimentary cancers we treat include esophageal cancer, gastric cancer, colorectal cancer, and gastrointestinal stromal tumor, as well as liver cancer, carcinoma of the biliary tract, and pancreatic cancer in the hepato-biliary-pancreatic area.
Transplantation surgery we perform includes hepatic transplantation, kidney-pancreas transplantation, and pancreatic transplantation.
We also perform surgical procedures on patients with inflammatory bowel diseases and provide medical care services to patients with functional gastrointestinal diseases.

Features

Our clinical section is committed to the development of new surgical therapies based on multimodality therapy of advanced cancers which have been considered to be intractable, such as pre-operative chemotherapy for patients with esophageal cancer, pre-operative chemoradiotherapy for patients with pancreatic cancer, molecular targeting treatment for patients with gastrointestinal stromal tumor, total pelvic exenteration for patients with recurrent rectal cancer, and hepatic intra-arterial chemotherapy combined with interferon for patients with advanced progcessive liver cancer. Laparoscopic surgery has been introduced to perform minimally invasive surgery on patients with gastric cancer, colorectal cancer, esophageal cancer, liver cancer, and pancreatic cancer. Single port surgery, in particular, which is conducted only inside the umbilical opening, is actively performed on patients with colorectal cancer. A clinical study on the effects of peptide vaccination on patients with advanced esophageal cancer and gastric cancer is being conducted to develop immunotherapy.
Our clinical section is designated as a facility for organ transplantation from brain-dead donors, and provides clinical services and conducts research on hepatic/pancreatic transplantation.
We also perform segmental hepatic transplantation from living donors, which has been covered by health care insurance since 2004.

Considerations in referring your patients to Gastroenterological Surgery

Gastroenterological Surgery accepts new patients on weekdays from Monday to Friday.
Feel free to contact our attending surgeon if your patient requires an emergency procedure. We accept patients with fulminant hepatitis mainly in the Trauma and Acute Critical Care Center and provide comprehensive medical services including hepatic transplantation.
Note that we do not accept patients with simple gallstones, who may not be treated in our hospital, including surgical procedures; however, gallstone patients with postoperative serious complications, e.g., patients with a ventricular assist device implanted, are accepted.
