Our clinical section has been a leader in pediatric surgical technology in Japan for many years. We have inherited these accumulated experiences, as well as expertise and skill, striving to provide medical care services as a core facility for advanced techniques to treat pediatric surgical patients in Japan. We are committed to treatment of patients with neonatal surgical diseases and malignant solid tumors, organ transplantation, as well as pediatric nutritional management, endoscopic surgery, and conduct research on these. Needless to say, we, as a leader in the community, actively provide medical care services for pediatric patients with general diseases who require surgical treatment.
At present, three supervisory doctors and five medical specialists, who are certified by the Japanese Society of Pediatric Surgeons, work together in our clinical section. We are committed to providing surgical procedures to pediatric patients, focusing on patients’ QOL and taking their growth into account, including endoscopic surgery, introduction of molecular target drug medication to treat pediatric cancers, promotion of hepatic/small bowel transplantation, regenerative medicine, and fetal therapy.
