The Value Of Endoscopic Ultrasonography In Laparoscopic Resection Of Hepatic Malignancies

Objectives:To observe clinical efficacy of laparoscopic ultrasonography in resection of hepatic malignancies.Methods:Thirty-two patients with malignant tumor of the liver conducted laparoscopic ultrasound-guided laparoscopic resection of hepatic malignancies.Many relative clinical data,including operative time,intraoperative hemorrhage,intraoperative blood transfusion,postoperative complications and other clinical data were retrospectively analyzed.Results:All of the 32 cases were successfully operated and had no transfer to open the abdomen.Among the 32 patients,15 cases had anatomic half liver and segmental resection,17 cases were irregular excision.And 6 patients underwent laparoscopic left hemihepatectomy,4 patients underwent laparoscopic right hemihepatectomy,2 patients underwent laparoscopic resection of right posterior lobe of liver,3 patients underwent laparoscopic left lateral lobectomy of liver.According to postoperative pathological statistics,there were 19 cases of primary hepatocellular carcinoma,10 cases of intrahepatic cholangiocarcinoma,and 3 cases of metastatic liver cancer.The average operative time was 248.11 ± 38.08 min,the intraoperative blood loss was 213 ± 74.91 ml,and the intraoperative blood transfusion volume was 304.78±53.78 ml.The average postoperative hospital stay was 7.89±2.23 d,and the recovery time of gastrointestinal function after operation was 3.67±1.56 d.A total of 3 patients had pulmonary atelectasis or pneumonia after operation.And no postoperative bleeding or bile leakage was found in 32 patients.In one case,the liver surface was covered with about 5mm liver cirrhosis nodules,the tumor location was near the inferior vena cava,and the liver failure occurred after local resection.After 2 weeks of conservative treatment,the patients recovered from the hospital.Conclusion:Laparoscopic ultrasonography is an important auxiliary tool in laparoscopic liver tumor resection,which improves the safety and success rate of laparoscopic liver tumor resection.
