Severance's Gastric Cancer Clinic conducts approximately 1,600 operations a year and therefore, seeks to offer optimal treatment to our patients. For example, an electrocautery tool incises with the least amount of bleeding and halves the operation time from 4 to 2 hours. With new and innovative surgical methods, and abandoning outdated and painful methods, the gastric cancer treatment team has reduced the days of hospitalization from 10-12 days to only 5-7 days. The surgeons of our Gastric Cancer Clinic have performed the largest number of gastric resections also using the da Vinci robotic surgical system.
