Stomach and Esophageal Surgery

Psychosomatic Medicine

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 strive to perform surgery that achieves radical cures while ensuring patient safety and maintaining postoperative quality of life. Patients who have undergone surgery at our hospital have successfully returned to their preoperative levels of social and professional activity. Additionally, laparoscopic surgery is performed for cancers detected in the early stages.

Gastric cancer

Striving to provide “body-friendly” treatment, we apply laparoscopic surgery techniques for cancers detected in the early 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 bleeding and perforation; benign diseases such as hernia; severe obesity.

Advanced treatments/ Specialized treatments

Esophageal cancer treatment

By enhancing the immune system preoperatively, we have achieved a reduction in postoperative complications. Our aims are to perform surgery without blood transfusion, to cause no deaths attributable to surgery, and allow early hospital discharge after surgery. Additionally, robot-assisted surgery (Non One-lung Ventilation Esophagectomy; NOVEL) is performed.

Gastric cancer treatment

With the goal of reducing the physical burden on patients, we apply laparoscopic surgery techniques. Preoperative chemotherapy is used to improve the prognosis. .

Severe obesity

Intragastric balloon placement is used for severely obese patients who do not respond to conventional treatment methods.
