Gastroenterological Surgery

We treat patients with any of the gastroenterological diseases.
In particular, we accept patients with gastrointestinal malignant tumors and for organ transplantation.
Gastrointestinal 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.


Gastroenterological Surgery is developing new surgical therapies based on multimodality therapies for advanced cancers which have been considered to be intractable, such as pre-operative chemotherapy for patients with esophageal or gastric cancer, pre-operative chemoradiotherapy for patients with pancreatic cancer, pre-operative molecular targeting treatment for patients with gastrointestinal mesenchymal tumor, and total pelvic exenteration for patients with recurrent rectal cancer. This 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.
Endoscopic surgery was introduced early on, and minimally invasive surgery is performed on patients with gastric cancer, colorectal cancer, esophageal cancer, liver cancer, and pancreatic cancer.Especially for gastric cancer and colorectal cancer, most operations are performed laparoscopically or with robotic (da Vinci) support, and the numbers of gastric cancer and rectal cancer operations with robotic (daVinci) support are both over 120 (as of March, 2020); one of the largest institutions in Japan. In addition, single port surgery, which is conducted only through the umbilical opening, is actively performed on patients with colorectal cancer.

More details, such as numbers of cases, can be found here (Japanese version only).

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.
