To investigate the clinical value of the three-dimensional (3D) reconstruction assisted hepatectomy for patients with liver cancer.

Retrospective analysis were performed from March 2017 to July 2019, in 46 patients who received laparoscopic hepatectomy with Surgical Difficulty Score of ≥8.46 patients were divided into enhanced CT group (n=22) and 3D reconstruction group (n=24) according to the different preoperative evaluation methods. SPSS 22.00 statistical software were used for data analysis. Measurement data such as lesion assessment, perioperative indexes and liver function indicators were expressed as (±s) and were examined by using independent t test. The accuracy of vascular invasion and complications were examined by using χ² or Fisher test. A P value <0.05 was considered as statistically significant difference.

All of 46 patients received successful laparoscopic hepatectomy without intraoperative death or conversion to laparotomy. There were 3 cases of surgical plan change among 24 patients in the 3D reconstruction group. The coincidence rate of vascular invasion was 57.1% (8/13) in the enhanced CT group, while 84.6% (10/13) in the 3D reconstruction group, without significant difference (P>0.05). The actual volume of resected liver and residual liver in the 3D reconstruction group were significantly different from those in the enhanced CT group respectively (P<0.05). The intraoperative blood loss in the 3D reconstruction group was significantly less than that in the enhanced CT group (P<0.05). The indexes of postoperative liver function in the 3D reconstruction group were significantly decreased, however with a lower drop than those in the enhanced CT group, with significant differences (P<0.05).

Three-dimensional reconstruction assisted hepatectomy has clinical value in treating patient with difficult liver cancers.
