Abstract　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.

Key words: early gastric cancer, function preserving gastrectomy, pylorus-preserving gastrectomy, local gastrectomy, sentinel lymph node navigation surgery

摘要：

随着检出率的逐年升高，越来越多的早期胃癌病人得以长期生存。保留功能的胃切除术在确保肿瘤根治的同时，保留胃的正常解剖生理功能，并改善病人术后生活质量，是未来早期胃癌治疗的发展趋势。其最经典的保留幽门的胃切除术，及在前哨淋巴结示踪基础上的胃局部切除术是目前最受关注的保留功能胃切除术式。而以上术式是否会带来肿瘤根治性上的风险、是否会增加手术并发症的发生以及术后病人的生活质量获益程度是影响其作为常规手术开展推广的主要因素。因此，对于目前胃功能保留手术所关注的相关问题进行系统、深入研究，提供有力的循证医学依据，将有助于早期胃癌外科治疗的新一轮革新。
