Surgery clinic oversees all operations. Some examples of procedures carried out at the surgery clinic include hernia, appendicitis, breast cancer, thyroid tumors, varicose veins, and transplant surgery in addition to stomach, colon, liver biliary tract, pancreas and other digestive cancers. Particularly, the incidence of gastric cancer is very high in Korea and the incidences of colorectal and breast cancers are also on the rise these days. For cancer, the most important part of the treatment is the surgery.
With the belief that laparoscopic surgery is not just another surgical method but a 'patient-centered surgical method which yields maximum results with minimum incision', the surgery clinic at Dongguk University Medical Center is investing in the best facilities and personnel for this new surgical procedure. Specifically, the laparoscopic procedure for colon and rectal cancer is recognized worldwide and the cure rate for cancer is surpassing the laparotomy procedure.
