They were first in demonstrating that a course of antibiotics lasting a week can cure H. pylori infection and successfully treat peptic ulcers and minimize their relapse. At the same time, Professor Sung and his research team pioneered the use of endoscopic treatment for ulcer bleeding to reduce the need for operative surgery. These research results have a major impact on and have changed the practice of gastroenterology worldwide.
