[Progress and controversy of indocyanine green (ICG) used in laparoscopic navigation surgery for advanced gastric cancer].

Indocyanine green (ICG) has been used as a novel tracer for mapping lymph nodes in navigation surgeries for many malignant tumors. Recently, ICG is mainly applied in sentinel lymph node biopsy for early gastric cancer, while its application in advanced gastric cancer is less reported. It was reported that application of ICG in locating perigastric lymph nodes could elevate the efficiency of lymphadenectomy for advanced gastric cancer. Besides, recognizing small lymph nodes and dissecting certain lymph node stations are its unique advantages. However, some problems remain unsolved, as few relevant research has been done. Based on conceptions of minimal invasive and precision medicine, ICG may play an important role in improving the accuracy of laparoscopic surgery for advanced gastric cancer in the future.吲哚菁绿(ICG)作为一种新型淋巴结示踪剂已应用于多种恶性肿瘤的导航手术。在胃癌中，ICG目前主要用于早期胃癌手术的前哨淋巴结活检，有关其在进展期胃癌手术中的研究相对较少。已有研究表明，ICG定位胃周淋巴结可使进展期胃癌手术淋巴结的清扫数量呈增加趋势，对清扫较小淋巴结和特殊区域淋巴结等方面具有独特优势。然而相关研究尚处于起步阶段，仍有许多临床问题尚未阐明。但在微创外科和精准医学理念的指导下，ICG的淋巴结定位技术将对提高进展期胃癌手术的精准性起到重要的辅助作用。.
