ABSTRACT
Objective:
To explore the application value of mixed-reality (MR) navigation combined with three-dimensional visualization technique in complicated hepatectomy.Methods:
A retrospective analysis of the clinical data of fifty patients with complex liver cancer who underwent liver resection in the Department of hepatobiliary surgery of Nantong Tumor Hospital during September 2015 to October 2017 was conducted. These patients were randomly divided into control group and experimental group, including 22 cases in the experimental group, using three-dimensional visualization technique for preoperative assessment, and MR surgery intraoperative navigation technology, and 28 cases in the control group, in which the three-dimensional visualization technique and the MR navigation were not performed. The surgeons of the two groups were the same. The preoperative, intraoperative and postoperative indexes of the two groups were compared and analyzed.Results:
There was no significant difference in preoperative indexes. But in the intraoperative indexes, the operation time [(82.3±10.4) min vs (96.6±22.7) min] and hepatic portal blocking time [(12.2±3.8) min VS (15.8±4.2) min] of the experimental group were significantly shorter than those of the control group, meanwhile, the amount of intraoperative bleeding [(486.4±118.5) ml vs (567.2±142.8) ml] and the volume of intraoperative blood transfusion of [(1.8±0.2) U vs (2.5±0.6) U] were significantly decreased. These differences were statistically significant. In the postoperatively, the total incidence of postoperative complications (4/22 vs 13/28) of the experimental group was lower than that of the control group, and the difference was statistically significant.Conclusion:
In complicated hepatectomy, MR intraoperative navigation combined with three-dimensional visualization technique which used for preoperative assessment can significantly shorten operation time, hepatic portal blocking time, significantly reduce intraoperative blood loss and transfusion volume, and significantly reduce the incidence of postoperative total complications, which is of clinical value.Palavras-chave
