Laparoscopic ultrasound combined with CT three-dimensional reconstruction for guiding laparoscopic hepatectomy / 中国医学影像技术

ABSTRACT

Objective To observe the value of laparoscopic ultrasound(LUS)combined with CT three-dimensional reconstruction for guiding laparoscopic hepatectomy(LH).Methods Data of 78 hepatocellular carcinoma(HCC)patients who underwent LH were retrospectively analyzed.The patients were divided into observation group(n=46)or control group(n=32)based on whether underwent preoperative CT three-dimensional reconstruction and LUS.Clinical data,perioperative data and prognosis were compared between groups.Results No significant difference of clinical data was found(all P＞0.05),whereas significant differences of tumor body mainly location,resection method,tumor resection margin,surgical operation time,intraoperative blood loss,postoperative hospital stay,postoperative complication grading and incidence were found between groups(all P＜0.05).During follow-up period,15 patients died in observation group and 14 died in control group.Significant difference of disease-free survival rate was detected between groups(x2=4.210,P=0.040).Conclusion LUS combined with CT three-dimensional reconstruction for guiding LH could reduce intraoperative injury and complication incidence,improving disease-free survival rate of HCC patients.
