Stomach and Esophageal Surgery
The Department of Stomach and Esophageal Surgery specializes in the diagnosis and surgical treatment of malignant diseases such as gastric and esophageal cancer, and benign diseases such as esophageal hiatal hernia. We also provide advanced surgical treatment for severe obesity.
Medical services
Supervising physicians and specialists affiliated with the Japan Surgical Society, the Japanese Society of Gastroenterological Surgery, the Japan Esophageal Society, and the Japanese Gastric Cancer Association provide highly professional treatment. Patients receive cutting-edge treatment from diagnosis to surgery and chemotherapy.
Diagnosis and treatment policy
We place the highest priority on the patient. Patients’ wishes regarding treatment decisions are confirmed and respected at all times. The most appropriate treatment method is selected by a group of specialists based on a careful review of the results of detailed and precise examinations, and patients are included in discussions about the selected method.
Specialized surgical procedures include:
Esophageal cancer
Based on our broad experience, we perform not only conventional esophagectomy with thoracotomy but robot assisted transmediastinal esophagectomy without thoracotomy that achieves radical cures while maintaining postoperative quality of life.
Gastric cancer
Striving to provide “body-friendly” treatment, we apply laparoscopic surgery techniques for cancers detected in the early and advanced stages.
Chemotherapy
Pre- and postoperative chemotherapy is used to increase the excision rate and improve the prognosis.
Target diseases
Gastric malignancy (gastric cancer, GIST, etc.), esophageal malignancy (esophageal cancer, malignant melanoma, sarcoma, etc.), emergency surgery for perforation, benign diseases such as inguinal and esophageal hiatal hernia, severe obesity.
Advanced treatments/ Specialized treatments
Esophageal cancer treatment
We perform robot-assisted transmediastinal esophagectomy without thoracotomy for the purpose of reducing postoperative complications and maintaining quality of life. Our robot-assisted esophagectomy shows shorter duration of hospital stay, lesser incidence of pneumonia and better quality of life compared with conventional esohpagectomy.
Gastric cancer treatment
With the goal of reducing the physical burden on patients, we apply laparoscopic or robot-assisted surgery techniques for gastric cancer and gastric GIST. We developed a new laparoscopy and endoscopy cooperative surgery technique (NEWS) and obtain good results.
Severe obesity
We apply laparoscopic sleeve gastrectomy for severely obese patients under insured health treatment.
Frequently performed tests and descriptions
Physical examinations such as blood, X-ray, ECG, respiratory function, endoscopy, CT, and PET-CT are performed as needed.
