Department of Surgery (Gastrointestinal Surgery) Director：NAKAYAMA, Goro (Associate Professor)

Globally acclaimed for expertise in multidisciplinary approach and minimally invasive approach in all fields of gastrointestinal and hepatobiliary-pancreatic surgery

Multidisciplinary treatment with surgery at the core for neoplasms of the digestive system has been tailored for each patient and delivered with care.


Medical Care System

Thirteen academic and nineteen medical members provide outpatient and inpatient medical care. The outpatient clinic is open Monday through Friday and is staffed by specialists in esophageal, gastric and colorectal diseases, including inflammatory bowel disease (IBD) surgery and bariatric surgery. Laparoscopic and robotic approaches are selected where applicable. Academic members and medical doctors collaborate with hospital treatments to provide appropriate medical care as a team.

Target Diseases

We treat patients with neoplasms and other intractable disorders of the esophagus, stomach, colon, and rectum, including gastrointestinal tract cancers and other malignancies, gastroesophageal reflux disease, achalasia, Crohn’s disease, and ulcerative colitis.

Strong Fields

For esophageal, gastric, colon, and other digestive tract cancers, we take a minimally invasive approach like laparoscopic or robotic surgery whenever possible and pursue a radical cure. We also work on conversion surgeries after intensive multimodal treatments and surgeries for cancer recurrence cases, which usually need high professionalism. As for IBD surgeries, total colectomy with ileal pouch-anal anastomosis for ulcerative colitis or recurrent surgeries for Crohn`s disease are frequently performed and have favorable surgical outcomes.

Clinical Results

The numbers of resections performed in 2023 are as follows, esophageal cancer: 83 (of those, 11 are open surgery, 35 are thoracoscopic surgery and 37 are robot-assisted surgery); gastric cancer: 57 (of those, 13 are open surgery, 22 are laparoscopic surgery, 22 are robot-assisted surgery); colorectal cancer: 151 (of those, 16 are open surgery, 93 are laparoscopic surgery, 42 are robot-assisted surgery); IBD: 78 (of those, 14 are open surgery, 52 are laparoscopic surgery, 12 are anal surgery).

Advanced Medicine and Research

Clinical studies on surgery and chemotherapy for esophageal, gastric and colorectal cancers are now conducted at many facilities, including hospitals affiliated with Nagoya University Hospital.
