Research Laparoscopic Ultrasound In Robot-assisted Resection Of Hilar Cholangiocarcinoma

ObjectiveTo investigate the value of the application of robot-assisted laparoscopicultrasonography (LUS) guided in the treatment of hilar cholangiocarcinoma.MethodsFrom July2009to December2010in Hepatobiliary Research Center，60patients suspicious hilar cholangiocarcinoma by imaging, which can doradical surgery and tolerate surgery, excluded because of serious heart andlung disease who can not tolerate surgery, which included78male cases and27females cases, aged range from34to83years old，mean age63.08±9.36years. Which received operator therapy under the robot-assisted LUS (35cases), robot-assisted (35cases) or abdominal (35cases). The curative effect,prognosis and complications were observed. Clinical data was observed andanalyzed, on the pathological diagnosis of hilar cholangiocarcinoma inpatients with follow-up results, and clinical data and follow-up results wereanalyzed to assess the clinical value of LUS.The data was analyzed statistically by using SPSS17.0software package.The quantitative data was expressed as mean±standard(x±s), and thequalitative data was expressed as cases or rate(%). between groupscompared using ANOVA analysis of variance, Number data using chi-squaretest、the fourfold table of fisher’s exact test and Wilcoxon rank sum test.Results with P<0.05was considered statistically significant. ResultsAll patients were treated with laparoscopic ultrasound guidedrobot-assisted radical resection, the rate of radical resection was100%（60/60）, robot-assisted LUS group, routine use of intraoperative LUS, Threecases change the surgical approach, because discovery of multiple small livermetastases (diameter<1.5cm). Patients in postoperative pathplogicalconfirmed hilar cholangiocarcinoma, To comparing the robot-assisted LUSgroup (group A), The oldest age, the longest operation time, the largestvolume of total blood loss, the shortest after bed time, the shortestpostoperative hospital stay, the least postoperative complications, the mostnumber of cases of R0resection were a significant different in robot-assistedgroup (group B) and abdominal group (group C)(*P<0.05). age, operationtime, volume of total blood loss, after bed time, postoperative hospital stay,postoperative complications, number of cases of R0resection were nosignificant different between group B and group C (*P>0.05).ConclusionsLUS has become a very useful means in laparoscopic surgery，inrobot-assisted operative LUS can not only help surgeons to select theoperative strategy and guide surgical approach, but also improve the rate ofradical resection of hilar cholangiocarcinoma, Provide a new method ofminimally invasive treatment of hilar cholangiocarcinoma.
