Efforts in Gastroenterology

Our gastroenterology department is operated by a very small staff of two specialists and three doctors who are undergoing training in the diagnosis and treatment of gastroenterology.For this reason, there is a limit to the number of medical treatments that can be accepted, but in the future we will make efforts to broadly support gastroenterology medical treatment in Science City, so please take a little long-term view.

A word to patients

We are very sorry for the small number of patients, but it is difficult to receive medical care at night or in an emergency.We apologize for any inconvenience this may cause to patients and nearby medical institutions, but with the cooperation of doctors in our general medicine department and emergency department, we will gradually build up our track record and secure doctors.

To local teachers

At present, there is a shortage of doctors who can cover the entire range of gastrointestinal procedures, so we are conducting medical care on a daily basis with a shortage of manpower.
Therefore, we would appreciate it if you could first introduce us to semi-urgent patients.
