由于右后肝蒂解剖结构复杂，标准化腹腔镜门区染色引导肝第6段解剖切除术（LPTAR-S6）的报道较少。本研究旨在阐明LPTAR-S6的吲哚菁绿（ICG）荧光染色方法。LPTAR-S6可以使用阳性和阴性荧光染色方法进行。我们对肝细胞癌患者实施了这两种方法。介绍了手术策略和技术细节。两名患者使用术前三维重建计划安全地接受了 LPTAR-S6。术中ICG荧光染色效果满意，解剖标志充分暴露。术前详细的三维重建方案，术中完整应用实时腹腔镜超声引导，ICG荧光染色可实现肝实质的准确横断LPTAR-S6 期间。© 2024。外科肿瘤学会。

Because of the complex anatomy of the right posterior hepatic pedicle, there have been few reports on standardized laparoscopic portal territory staining-guided anatomical resection of liver segment 6 (LPTAR-S6). This study aimed to elucidate the indocyanine green (ICG) fluorescence staining methods for LPTAR-S6.LPTAR-S6 can be performed using positive and negative fluorescence staining approaches. We implemented these two approaches for patients with hepatocellular carcinoma. Descriptions of the surgical strategy and technical details are presented.Two patients safely underwent LPTAR-S6 using a preoperative three-dimensional reconstruction plan. The intraoperative ICG fluorescence staining effect was satisfactory, and the anatomical landmarks were fully exposed.A detailed preoperative three-dimensional reconstruction plan, complete intraoperative application of real-time laparoscopic ultrasound guidance, and ICG fluorescence staining can result in accurate transection of the liver parenchyma during LPTAR-S6.© 2024.
