Near-infrared imaging combined with intraoperative ultrasound in laparoscopic liver tumor resection / 中华普通外科杂志

ABSTRACT

Objective To evaluate intraoperative ultrasound combined with near-infrared imaging in laparoscopic liver tumor resection.Methods 15 cases undergoing laparoscopic hepatectomy at our department from Ju12017 to Sep 2017 were enrolled in this study.We observed the volume of resected liver,ICG test,the ability of detected lesion overlooked by preoperative imaging,operation time,blood loss,hospital stay,postoperative complication,final pathological result,and tumor margin.Results We have done laparoscopic hepatectomy in 15 cases by intraoperative ultrasound and near-infrared imaging.There was no conversion to open surgery,blood loss was (220 ± 159) rnl,operation time was (136 ±6) min,hospital stay was (8.6 ± 2.1) d,tumor margin was (1.6 ± 1.1) cm,all were tumor negative.There was no major complications such as postoperative bleeding,nor perioperative death.There were pleuraleffusion in 3 cases and bile leakage in one,all were cured by drainage.Conclusion Intraoperative ultrasound combined with near-infrared imaging during the process of laparoscopic hepatectomy helps in assuring safe tumor margin and preserving normal liver parenchyma.
