ABSTRACT
As the diagnosis rate of early gastric cancer is increasing annually, the current hot spot in the treatment of early gastric cancer is how to better preserve the anatomical structure and physiological function of the stomach and improve the quality of life of patients after surgery under the premise of tumor eradication. Therefore, function-preserving gastrectomy has been the trend of surgical treatment for early gastric cancer. It is not just a modified gastrectomy, but a better combination of improved surgical techniques and the concept of function-preserving treatment, rather than being limited to traditional surgical treatments. Currently, the routine function-preserving gastrectomy mainly includes pylorus-preserving gastrectomy, proximal gastrectomy and partial gastrectomy combined with endoscopy. In addition, with the deeper understanding of metastasis pattern of gastric cancer and the development and popularization of minimally invasive techniques, laparoscopic and endoscopic cooperative surgery is gradually gaining attention. The application of laparoscopic and endoscopic hybrid surgery combined with sentinel lymph node navigation is anticipated in the treatment of early gastric cancer.

With the detection rate of early gastric cancer increases annually, more and more patients can survive for a long time after surgery. Thus, surgeons have paid more attention to preserve the function of the remnant stomach, limit the surgical trauma and improve the quality of life. Pylorus-preserving gastrectomy andlocal gastrectomy are the most common kind of function preserving gastrectomy. The key points we concern are whether they will bring about the risk of radical tumors, whether they will increase the occurrence of surgical complications and whether they are difficult to popularize. The systematic and in-depth study of the key aspects of these function preserving gastrectomy and the provision of a strong evidence-based medical basis will contribute to a new round of innovation in the surgical treatment of early gastric cancer.
ABSTRACT
Gastric cancer is most common cancer in Korea. Surgery is still the main axis of treatment. Due to early detection of gastric cancer, the innovation of surgical instruments and technological advances, gastric cancer treatment is now shifting to a new era. One of the most astonishing changes is that minimally invasive surgery (MIS) is becoming more dominant treatment for early gastric cancer. These MIS are represented by endoscopic resection, laparoscopic surgery, robotic surgery, single-port surgery and natural orifice transluminal endoscopic surgery. Among them, laparoscopic gastrectomy is most actively performed in the field of surgery. Laparoscopy-assisted distal gastrectomy (LADG) for early gastric cancer (EGC) has already gained popularity in terms of the short-term outcomes including patient's quality of life. We only have to wait for the long-term oncologic results of Korean Laparoscopic Gastrointestinal Surgery Study Group. Upcoming top issues following oncologic safety of LADG are function-preserving surgery for EGC, application of laparoscopy to advanced gastric cancer and sentinel lymph node navigation surgery. In the aspect of technique, laparoscopic surgery at present could reproduce almost the whole open procedures. However, the other fields mentioned above need more evidences and experiences. All these new ideas and attempts provide technical advances, which will minimize surgical insults and maximize the surgical outcomes and the quality of life of patients.
