[Multimodality navigation for liver resection of complicated alveolar echinococcosis]

Objective: To investigate the clinical application of multimodality navigation for liver resection in the treatment of complicated alveolar echinococcosis (AE). Methods: From October 2019 to February 2020, the clinical data and perioperative results of patients with AE treated by surgery in our department were retrospectively studied. Hepatic parenchyma disconnection plane and liver resection were navigated and performed with three-dimensional reconstruction and HITACHI real-time multi-image fusion interventional navigation system (RVS). Results: All of six patients were successful performed radical liver resection without mortality. The operation time was (301±106)min and the median blood loss was 200 ml. Two patients needed blood transfusion intraoperative (33.33%). The postoperative hospital stay was (10.8±2.8) day, and the cost of hospitalization was (82 584±995.61) yuan. Clavien-Dindo grade Ⅲ complication occurred in one patient. Conclusions: Multimodality navigation might provide precise intraoperative navigation of the surgical plane and effectively assist liver resection for the treatment of complicated AE.
