17、eved Lym,Conclusion-LDG in general,With recent advent of instrumentation, laparoscopic approach is increasingly applied for patients with early cancer. Proper extent of lymph node dissection for early cancer appears feasible with keeping lower incidence of morbidity. However, oncologic adequacy of lymph node dissection is not proved at present.,本胃癌腹腔镜,Conclusion-LDG in general Wi,
