Application Experience Of Laparoscopic Ultrasound In Hepatobiliary And Pancreatic Surgery

Objective:In order to improve the accuracy of hepatobiliary and pancreatic surgery,we used laparoscopic ultrasound or laparoscopic ultrasound combined with indocyanine green imaging technology to assist hepatobiliary and pancreatic laparoscopic surgery,and to explore the effect of laparoscopic ultrasound assisted hepatobiliary and pancreatic surgery on patients.And compare the sensitivity of laparoscopic ultrasound and preoperative different examination methods in the detection of hepatobiliary and pancreatic diseases.Methods:The clinical data of 95 patients with hepatobiliary and pancreatic diseases who need surgical treatment in our hospital(Shengjing Hospital Affiliated to China Medical University)from September 2018 to December 2020 were retrospectively analyzed.There were 34 patients with liver diseases,46 patients with gallbladder and bile duct diseases,and 15 patients with pancreatic diseases.They were divided into two groups according to whether laparoscopic ultrasound was used in operation:experimental group(laparoscopic ultrasound group)45 cases;control group(without laparoscopic ultrasound group)50 cases.The operation effect(intraoperative blood loss,operation time,operation adverse events,postoperative hospital stay,hospitalization expenses,etc.)of the two groups were compared.The sensitivity of preoperative transabdominal ultrasound,abdominal computed tomography and intraoperative laparoscopic ultrasound in the experimental group was compared and analyzed.Results:The demographics and preoperative diagnosis of the two groups were similar(P > 0.05).The intraoperative blood loss(99.2±132.4 vs 161.7±151.8,z=-2.89,P=0.04)and the effect of surgery on human hemoglobin(14.5 ± 10.2 vs19.5 ± 10.8,t =-2.350,P = 0.021)could be reduced by using LUS assisted laparoscopic surgery.The sensitivity of LUS for the diagnosis of hepatobiliary and pancreatic diseases was higher than that of percutaneous ultrasound and CT(97.7%vs 84.1% vs 86.4%),and the detection rate of LUS for hepatobiliary and pancreatic diseases was significantly higher than that of percutaneous ultrasound(97.7% vs84.1%,2 = 4.950,P = 0.029).Conclusion:As a combination of ultrasound and minimally invasive technology,laparoscopic ultrasound has the advantages of convenience,rapidity,real-time and reliability.In clinical practice,it has feasibility,safety and accuracy,can improve the operation efficiency and better realize the visualization of hepatobiliary and pancreatic surgery.
