Message from the Director of the Department
We provide comprehensive surgical consultation and care in many specialties including esophageal surgery, gastric surgery, and colon and rectal surgery. Minimally invasive laparoscopic and thoracoscopic surgery and robotic surgery are actively performed for functional conservation and early recovery after surgery. Chemotherapy is an available option, when indicated.
Department of Gastroenterological
Scope of Target Diseases
◎ Esophageal diseases: Surgery, chemotherapy and radiotherapy for esophageal cancer, surgery for benign tumor such as leiomyoma, benign diseases such as gastroesophageal reflux disease, hiatal hernia, esophageal achalasia and esophageal diverticulum.
◎ Gastric diseases: Surgery and chemotherapy for gastric cancer and submucosal tumor such as gastrointestinal stromal tumor (GIST), and surgery for severe obesity, called bariatric surgery.
◎ Colorectal disease: Surgery, chemotherapy and radiotherapy for colorectal cancer, and surgery for small intestine tumor such as GIST, inflammatory bowel diseases such as ulcerative colitis and Crohn’s disease, anal diseases such as hemorrhoid and rectal prolapse, and appendicitis.
Features and Description of Medical Care
◎ Esophageal surgery: As a leading hospital in Japan, we have many surgical cases for esophageal cancer. We strive for “less-invasiveness” in esophageal cancer surgery which is originally “high invasive” by introducing thoracoscopic laparoscopic and robotic surgery. In addition, for patients with far-advanced cancer, we use multidisciplinary treatments such as surgery, chemotherapy, and radiotherapy to provide the most appropriate treatment for each individual patient.
◎ Gastric surgery: We provide less-invasive and function-preserving surgery for gastric cancer by standardizing laparoscopic surgery and robotic surgery, which currently accounts for more than 90%, and introducing laparoscopy and endoscopy cooperative surgery (LECS) . We also aim at improved outcomes for advanced gastric cancer by the use of multimodal therapies including adjuvant chemotherapy before and after surgery.
◎ Colorectal surgery: We provide less-invasive laparoscopic and robotic surgery for colorectal cancer, notably hybrid surgery performed by two-team transperitoneally and transanally for low rectal cancer. We also provide less-invasive laparoscopic surgery with satisfactory cosmetic outcomes especially for IBD, which is common among young people.
