Three-dimensional location approach with silk thread guided hepatectomy for liver tumor

Figure 1 Surgical procedure of three-dimensional location approach with silk thread guided hepatectomy. A: Three-dimensional reconstruction of the intrahepatic vessels and tumors was performed; B: The key points of the cutting edge were demarcated with small virtual sticks; C: The lines were connected with the key points on the surface of the virtual liver model; D: The length of each line was measured; E: The visceral face of the liver model; F: Prepare silk thread with the same length and place it at the anatomical position of the liver surface. The shape of the silk thread is the liver cutting line; G: The liver was resected according to the shape of the silk thread, and the middle hepatic vein was exposed in the section; H: Liver section after hepatectomy; I: After the complete resection of the liver lesion, the section shows that the tumor is completely removed with a safe margin, which is consistent with the preoperatively planned resection margin.
