Application of intraoperative ultrasonography in robot-assisted laparoscopic hepatectomy / 中华超声影像学杂志

ABSTRACT

Objective To explore the application and significance of intraoperative laparoscopic ultrasound( IOUS) in robot-assisted laparoscopic hepatectomy . Methods From February 2015 to February 2017 ,135 patients undergoing liver resection with robotic approach were enrolled in the study . All data about demographic ,surgical procedure and postoperative course were collected prospectively and analyzed . IOUS was routinely performed in these patients . To assist the localization and resection of liver tumor ,a four steps IOUS protocol in robotic liver surgery was proposed ,including exploration ,verification ,guidance , and confirmation . If necessary ,intraoperative laparoscopic ultrasound guided microwave ablation of liver tumor to complete the treatment . Results A total of 11 additional lesions in 11 patients were detected in 135 patients ,7 patients accepted strategic surgical modification 4 cases were enlarged resection ,and 3 cases were treated with microwave ablation . There were only 17 patients lost blood more than 1000 ml in all patients . No patient suffered from any single or multiple organ dysfunctions ,and there was no mortality observed . Conclusions IOUS is indispensable to understand lesions and vessels ,confirm the complete resection of the tumor in robot-assisted laparoscopic hepatectomy . It is also a necessary tool for the microwave ablation of liver tumor .
