超声对腹腔镜胆囊切除术难易程度的估测

目的探讨超声评价腹腔镜胆囊切除术（laparoscopic cholecystectomy,LC）难易程度的临床应用价值。方法采用灰阶超声,估测32例拟行腹腔镜胆囊切除术患者的胆囊粘连情况,与术中直接观察结果进行比较分析,并对多种可能影响手术的因素作相关性分析。结果超声可较清晰显示胆囊三角形态,超声对其是否粘连的观察结果与术中直接观察结果比较差异无统计学意义（P〉0.05）。手术时间与胆囊壁厚度、胆囊三角有无粘连呈正相关关系（P〈0.05）,与胆囊大小、胆囊三角的显示情况无相关关系（P〉0.05）。结论超声对胆囊三角是否粘连的术前评估具有一定的价值。

Ultrasonic value in predicting difficulty in laparoscopic cholecystectomy

Objective To study the ultrasonic value in predicting difficulty in laparoscopic cholecystectomy(LC).Methods Predicting the gallbladder adherence of 32 LC patients with gray scale ultrasound,analyzing the difference between the data with ultrasound and that in operation,and making the relevant analysis to many kinds of possible factors affecting the operation time.Results Ultrasound could demonstrate the shape of cystohepatic triangle clearly,and there was no significant statistical difference in observing adherence between ultrasound and by surgical operation(P>0.05).There was positive correlation between operation time and the thickness of gallbladder wall or the adherence of cystohepatic triangle(P<0.05).There was no correlation between operation time and gallbladder volume or the adherence of cystohepatic triangle(P>0.05).Conclusion Ultrasound is an useful and optimal image application for predicting adherence in cystohepatic triangle.
