The Department of Gastrointestinal Surgery is composed of three departments of esophageal surgery, gastric surgery, and colorectal surgery, and it conducts research on the entire gastrointestinal tract. We conduct clinical research based on clinical activities and basic research in specialized laboratories within and outside the department, which is applied to clinical practice. We provide up-to-date and high-level gastrointestinal surgery and pre- and post-graduate education.

1) Development of esophageal surgery.
2) Development of gastric surgery.
3) Development of colorectal surgery.

The history of the department started as both the Department of Esophageal and General Surgery and the Department of Surgical Oncology of TMDU, and many surgeons and researchers in various specialties have gathered and have been keeping a high level of activities. Our main purposes of education are to make the post-graduate physicians grown up to excellent surgeons and to contribute in development of medical/surgical sciences. Surgeons with high-level medical knowledge and techniques are expected to grow up in this department. Moreover, making surgeons with matured humanity is one of the purposes. The department has a peaceful atmosphere and stands for active work in solving difficult problems.

Basic gastrointestinal and general surgery knowledge and skills are the program's cornerstones. The program aims to cultivate a high level of practical ability to quickly perform logical and objective medical treatment, backed up by the skill and kindness of a clinician.

Not only to engage in specialized training and research activities within the university but also to contribute to community medicine while improving their abilities as gastrointestinal and general surgeons at the affiliated hospitals. They are also encouraged to study in Japan and overseas and to work at overseas bases.

　Main clinical services are diagnosis and treatment for esophageal, gastric and colorectal diseases. Post-graduate students learn and study general surgery and sub-specialty, e.g. esophageal surgery, gastric surgery and colorectal surgery. The territory of clinics is wide and the department provides a full spectrum of standard and special technologies such as minimally invasive surgery and extended radical surgery for malignancies.
