Intraoperative determination of resection margin and adequate residual liver parenchyma are the key points of hepatectomy for the treatment of liver tumors. Intraoperative ultrasound and indocyanine green fluorescence navigation are the most commonly used methods at present, but the technical barriers limit their promotion.
To evaluate the value of the three-dimensional location approach with silk thread (3D-LAST) in precise resection of liver tumors.
From September 2020 to January 2022, 8 patients with liver tumors including hepatocellular carcinoma, intrahepatic cholangiocarcinoma, hilar cholangiocarcinoma, and gastric cancer liver metastasis were included in this study. All patients underwent 3D-LAST in precise resection of liver tumors.
All patients (8/8, 100%) underwent the operation successfully without any complications. During the mean follow-up of 8.7 months, all patients survived without tumor recurrence.
In conclusion, the 3D-LAST is a safe and effective new method for liver intraoperative navigation, which is practical and easy to promote.
术中确定切除边缘和足够的残余肝实质是肝肿瘤切除术治疗的关键要点。术中超声和吲哚菁绿荧光导航是目前最常用的方法，但技术障碍限制了它们的推广。
评估丝线三维定位法（3D-LAST）在肝肿瘤精确切除中的价值。
2020年9月至2022年1月，本研究纳入8例肝肿瘤患者，包括肝细胞癌、肝内胆管癌、肝门胆管癌和胃癌肝转移患者。所有患者均采用3D-LAST进行肝肿瘤精确切除。
所有患者（8/8，100%）手术成功，无任何并发症。平均随访8.7个月期间，所有患者均存活，无肿瘤复发。
总之，3D-LAST是一种安全有效的肝脏术中导航新方法，实用且易于推广。
