Since its conception in 2005, we believe that the Korean Laparoendoscopic Gastrointestinal Surgery Study (KLASS) group has played a pivotal role in laparoendoscopic technique
and research in gastrointestinal surgery.
To develop diverse minimally invasive surgeries and to find concrete evidences for clinical application, the KLASS group conducted prospective multi-center phase III trials.
We published outstanding results in prestigious journals, which led to significant improvement in surgical practice.
Furthermore, we made a constant effort by continue intensive academic exchanges with Northeast Asian countries to establish a “global standard” of laparoendoscopic gastrointestinal surgery.
