摘要:

目的    探讨三维可视化技术在医源性胆管损伤后狭窄修复手术的术前评估和手术方案选择中的价值。方法    回顾性分析上海交通大学医学院附属仁济医院胆胰外科2014年1月至2018年3月接受手术治疗的20例医源性胆管损伤后狭窄病人的临床资料。采用三维可视化工作站对上腹部增强CT进行三维可视化处理和评估。利用增强CT和三维可视化技术评估脉管变异情况、胆管狭窄的位置、肝脏萎缩情况、有无肝门旋转、有无合并肝内胆管结石并测量肝门深度等,比较依据三维可视化评估制定的手术规划与实际施行的手术方式的一致性,随访远期胆管再狭窄情况、肝功能状况与生活质量。结果    三维可视化技术评估胆管狭窄Bismuth分型与术中评估完全一致,增强CT评估将2例Bismuth Ⅰ型胆管狭窄误认为Bismuth Ⅱ型,1例Ⅱ型误认为Ⅰ型。三维可视化技术可发现增强CT不能发现的肝动脉和门静脉变异,测量20例病人的肝门深度值范围为(-10.1~+21.1)mm,左肝管横部长度为(15.2±4.6)mm。利用三维可视化技术评估制定的手术规划与实际手术方式完全符合,术中无血管损伤和大出血的发生。结论    利用三维可视化技术能提高术前评估的准确性,有利于制定合理的手术路径与方案,提高手术安全性。

Abstract    Objective    To explore the value of 3-D visualization technique in preoperative evaluation and operation procedures selection in the repairing of iatrogenic biliary strictures. Methods    The clinical data of 20 patients with biliary stricture due to iatrogenic injury who were underwent surgical treatment from January 2014 to March 2018 in Department of Pancreaticobiliary Surgery,Renji Hospital, Shanghai Jiao Tong University School of Medicine were analyzed retrospectively. 3-D visualization processing and evaluation were done by 3-D visualization workstations based on abdominal enhanced CT data of all the patients. Variations of hepatic vasculatures,location of biliary strictures,liver atrophy,porta hepatis rotation,hepatolithiasis and depth of porta hepatis were evaluated by enhanced CT and 3-D visualization technique respectively. The consistence between preoperative operation plan made by 3-D visualization and actual operation procedures were compared. Patients were followed up of biliary stricture,liver function and quality of life in the long-term. Results    The Bismuth classification of biliary stenosis evaluated by 3-D visualization technique was completely consistent with intraoperative evaluation,while enhanced CT mistaked 2 cases of Bismuth I for Bismuth Ⅱ and one case of Bismuth Ⅱ for Bismuth Ⅰ. Several variations of hepatic artery and portal vein were ignored by enhanced CT,but detected by 3-D visualization technique.The range of depth of portal hepatic and length of transverse part of left hepatic duct were(-10.1~+21.1)mm and(15.2±4.6)mm respectively. Preoperative operation plan made by 3-D visualization and actual operation procedures were identical. Vascular injury and massive hemorrhage did not occur intraoperatively. Conclusion    The accuracy of preoperative evaluation can be improved by using 3-D visualization technology,which is conducive to the formation of reasonable surgical path, plan and improvement of surgical safety.
