超声检查对腹腔镜胆囊切除术难度的预测价值

目的:评价术前超声检查对预测慢性胆囊炎患者行腹腔镜胆囊切除术(laparoscopic cholecystectomy,LC)难度的应用价值.方法:793例患者因慢性胆囊炎行LC,术前超声检查对胆囊轮廓、胆囊颈部、囊壁厚度、囊壁回声、囊内回声情况进行综合分析,评估胆囊周围、Calot三角区的粘连程度,并与手术病理进行对...

Value of preoperative sonography in predicting difficulties of laparoscopic cholecystectomy

Objective:To discuss the value of preoperative ultrasound in predicting possible difficulties of laparoscopic cholecystectomy(LC).Methods:A total of 793 patients with chronic cholecystitis received ultrasonography examination.Before LC,the gallbladders were comprehensively examined to observe the contour,gallbladder necks,wall thickness,wall echoes,intra-cyst echoes in these patients.Preoperative data and intraoperative data were compared to access pericholecystic and Calot triangular area adherence.Results:Sensitivity,specificity and accuracy of preoperative sonography for predicting the difficulty of LC was 91.32%,97.51% and 95.08%,respectively.Conclusions:Preoperative ultrasonography is valuable for predicting difficulties during LC.
