Detailed Description
Intervention of the experimental group: based on high-quality thin-slice CT image reconstruction 3d visualization model to guide preoperative planning and surgery. The surgical process and perioperative management are as follows: All patients in this study were operated by the medical team whose main member was the medical team leader, and all patients were treated with anatomic hepatectomy. The main points of anatomic hepatectomy are summarized as follows :(1) determine and mark the boundary of liver segment according to ischemia line or staining. (2) The postoperative liver section should fully expose the iconic veins and vessels. (3) The initial part of Glisson's pedicle of the target liver segment was severed. Tissue was taken from the surgical margins of all patients and sent to frozen sections for examination. Routine pathological examinations were performed on all resected liver after surgery. Postoperative patients were treated with relevant perioperative symptomatic treatment, and blood routine examination, liver function and coagulation function were detected on the 1st, 3rd and 5th day after surgery.
Intervention in the control group: preoperative planning and operation were guided based on high-quality thin-slice CT images. Perioperative management same as above.

Experimental: 3d reconstruction visualization model to guide preoperative planning and surgery
All patients in this study were operated by the medical team whose main members were the medical team leader, and all patients underwent anatomic hepatectomy.
The main points of anatomic hepatectomy are summarized as follows :(1) determine and mark the boundary of liver segment according to ischemia line or staining.
(2) The postoperative liver section should fully expose the iconic veins and vessels.
(3) The initial part of Glisson's pedicle of the target liver segment was severed.
Tissue was taken from the surgical margins of all patients and sent to frozen sections for examination.
Routine pathological examinations were performed on all resected liver after surgery.
Postoperative patients were treated with relevant perioperative symptomatic treatment, and blood routine examination, liver function and coagulation function were detected on the 1st, 3rd and 5th day after surgery.

3D visualization technology refers to the conversion of 2d imaging data such as CT and MR into 3D stereoscopic images through computer calculation, analysis and reconstruction, visually separating the shapes and spatial distribution features of targets such as liver, blood vessels and tumors directly, accurately and quickly to present three-dimensional views.
Combined with transparency, rotation, scaling and measurement techniques, real-time and interactive 3D dynamic analysis of 3d visual model is carried out.
In addition, the computer was used to simulate the operation, and the feasible surgical plan was discussed.
The best surgical plan was selected based on the patient's individual data.

No Intervention: Based on high-quality thin slice CT images to guide preoperative planning and surgery.
All patients in this study were operated by the medical team whose main members were the medical team leader, and all patients underwent anatomic hepatectomy.
The main points of anatomic hepatectomy are summarized as follows :(1) determine and mark the boundary of liver segment according to ischemia line or staining.
(2) The postoperative liver section should fully expose the iconic veins and vessels.
(3) The initial part of Glisson's pedicle of the target liver segment was severed.
Tissue was taken from the surgical margins of all patients and sent to frozen sections for examination.
Routine pathological examinations were performed on all resected liver after surgery.
Postoperative patients were treated with relevant perioperative symptomatic treatment, and blood routine examination, liver function and coagulation function were detected on the 1st, 3rd and 5th day after surgery.
