OBJECTIVE: To evaluate the value of the three-dimensional visualization technology for the preoperative assessment of liver autotransplantation for end-stage hepatic alveolar echinococcosis.
METHODS: A total of 8 patients with end-stage hepatic alveolar echinococcosis undergoing liver autotransplantation in Qinghai Provincial People's Hospital from May 2013 to July 2017 were collected. All cases received preoperative abdominal CT scanning and dynamic three-phase enhanced CT scanning, and the original CT data were transferred to the human 3D visualization virtual surgical planning system. The volumes of Echinococcus multilocularis and pre-resected liver were measured using the 3D visualization reconstruction, and the relationship between the lesion and the neighboring tissues was observed. The value of the 3D visualization technology for the preoperative assessment of liver autotransplantation for end-stage hepatic alveolar echinococcosis was assessed by comparing with the intraoperative findings.
RESULTS: The 3D visualization reconstruction model clearly displayed the adjacent relationship between the lesions of end-stage hepatic alveolar echinococcosis and the neighboring tissues, and no significant difference was seen between the pre-resected liver volume in 3D visualization reconstruction model and the actually resected liver volume (t = 1.083, P > 0.05).
CONCLUSIONS: 3D visualization technology is feasible to develop a reasonable scheme for liver resection and vascular anastomosis for end-stage hepatic alveolar echinococcosis prior to liver autotransplantation, which may increase the success of surgery and improve the prognosis.
