Message from the Head of the Department

    Dokkyo Medical University Saitama Medical Center is located in the east area of Saitama prefecture and has essential roles as a core medical institution of this area in which more than one million people live. Our department is mainly focusing on surgical treatment of digestive disease. Our mission is to provide highly advanced medical care and general surgical treatment.
     As a core medical institution, we provide advanced medicine. We mainly focus on the treatment for gastrointestinal malignancies. We introduced multidisciplinary treatment for the tumors in the advanced stage, which combines chemo(radio)therapy and aggressive surgical treatment. To achieve curative resection, we use the highly advanced surgical technique, such as vascular resection and reconstruction. In addition, we are widely using laparoscopic and robotic surgery. These minimally invasive surgical procedures help patients’ early recovery and better quality of life.
     We also perform general surgery, such as inguinal hernia repair and cholecystectomy. We also treat emergency cases, such as perforation of intestine and traumatic surgery, cooperating with the department of emergency and critical medicine.
 We perform more than 1,000 surgeries per year. You can learn a lot of things regarding surgery through these abundant cases. We welcome many residents and students to our department.

Activities

  • Diagnosis and treatment of digestive diseases (cancer/inflammation, etc.) such as the esophagus, stomach, duodenum, colon, rectum, anus, and hepatobiliary pancreatic diseases.
  • Provide personalized medical care according to the patient's status combining the surgical operation (laparoscopic surgery, open surgery, robot-assisted surgery, etc.) and cancer chemotherapy (preoperative-, postoperative- and multidisciplinary treatment, etc.)
  • Laparoscopic surgery for benign diseases such as cholelithiasis, acute appendicitis, and hernia.
  • Surgical treatment of emergency abdominal diseases (such as gastrointestinal perforation and ileus, etc.).
  • Diagnosis and treatment of acute pancreatitis and chronic pancreatitis.

  • For esophageal cancer, we provide multidisciplinary treatment in collaboration with other departments by combining multidisciplinary treatments such as minimally invasive surgery (endoscopes, thoracoscopes, and laparoscopes), radiotherapy, and chemotherapy.
  • For gastric and rectal cancers, we perform laparoscopic or robot-assisted surgery in almost all cases.
  • For colon cancer, laparoscopic surgery is actively indicated.
  • For advanced colorectal cancer, chemotherapy is used to control cancer before surgery.
  • Our section has three highly skilled hepatobiliary and pancreatic surgeons certified by the Japanese Society of Hepato-Biliary-Pancreatic Surgery and provides safe and reliable treatment.
  • We perform aggressive surgical resection for advanced liver, biliary tract, and pancreatic cancer, using highly advanced surgical techniques such as vascular resection.
  • We aggressively perform robotic surgery as a minimally invasive procedure for patients with pancreatic cancer.
  • We perform laparoscopic surgery for liver and pancreatic tumors.
  • For advanced digestive cancers, we aggressively provided multidisciplinary treatment combined with chemotherapy and radiotherapy according to each patient's medical condition.
