  • Application of multimode imaging technology in precise hepatectomy for huge hepatocellular carcinoma

    ObjectiveTo study clinical practical value of multimode imaging technique in precise hepatectomy for huge hepatocellular carcinoma (HCC). MethodsThe clinicopathologic data of patients with huge HCC who underwent precise hepatectomy in Yuebei People’s Hospital from Jan. 2018 to Dec. 2020 were collected. The three-dimensional (3D) reconstruction, 3D visualization, 3D printing, and augmented reality (AR) were used to guide preoperative evaluation, surgical planning, and surgical navigation. The liver function indexes, surgical mode, operative time, intraoperative bleeding, volume of resected liver, postoperative hospitalization, and complications were analyzed. ResultsThere were 23 patients in this study, including 18 males and 5 females, with (56.8±8.1) years old. The virtual tumor volume assessed by multimodal imaging technology was (865.2±165.6) mL and the virtual resected liver volume was (1 628.8±144.4) mL. The planned operations were anatomical hepatectomy in 19 patients and non-anatomical hepatectomy in 4 patients. The actual operation included 17 cases of anatomical hepatectomy and 6 cases of non-anatomical hepatectomy, which was basically consistent with the results of AR. The operative time was (298.4±74.5) min, the median hepatic blood flow blocking time was 20 min, and the intraoperative bleeding was (330.4±152.8) mL. Compared with preoperative levels, the levels of hemoglobin and albumin decreased temporarily on the first day after operation (P<0.05), and then which began to rise on the third day and basically rose to the normal range; prothrombintime, total bilirubin, alanine aminotransferase, and aspartate aminotransferase increased transiently on the first day after operation (P<0.05), then which began to decline to the normal levels. There were no serious operative complications and no perioperative death. The median follow-up time was 18 months, the tumor recurrence and metastasis occurred in 3 cases. ConclusionFrom preliminary results of this study, it could improve surgical safety and precision of hepatectomy for huge HCC by preoperative precise assessment and operation navigation in good time of multimode imaging technology.
