Cholecystolithiasis is a common disease in the elderly patient. The routine therapy is open or laparoscopic cholecystectomy. In the previous study, we designed a minimally invasive cholecystolithotomy based on percutaneous cholecystostomy combined with a choledochoscope (PCCLC) under local anesthesia.
To investigate the effect of PCCLC on the gallbladder contractility function, PCCLC and laparoscope combined with a choledochoscope were compared in this study.
The preoperational age and American Society of Anesthesiologists (ASA) scores, as well as postoperational lithotrity rate and common biliary duct stone rate in the PCCLC group, were significantly higher than the choledochoscope group. However, the pre- and postoperational gallbladder ejection fraction was not significantly different. Univariable and multivariable logistic regression analyses indicated that the preoperational thickness of gallbladder wall (odds ratio [OR]: 0.540; 95% confidence interval [CI]: 0.317-0.920; =0.023) and lithotrity (OR: 0.150; 95% CI: 0.023-0.965; =0.046) were risk factors for postoperational gallbladder ejection fraction. The area under receiver operating characteristics curve was 0.714 (=0.016; 95% CI: 0.553-0.854).
PCCLC strategy should be carried out cautiously. First, restricted by the diameter of the drainage tube, the PCCLC should be used only for small gallstones in high-risk surgical patients. Second, the usage of lithotrity should be strictly limited to avoid undermining the gallbladder contractility and increasing the risk of secondary common bile duct stones.
胆囊结石是老年患者的常见疾病。常规治疗方法是开腹或腹腔镜胆囊切除术。在之前的研究中,我们设计了一种在局部麻醉下基于经皮胆囊造瘘术联合胆道镜的微创胆囊取石术(PCCLC)。
为了研究PCCLC对胆囊收缩功能的影响,本研究对PCCLC与腹腔镜联合胆道镜进行了比较。
PCCLC组的术前年龄和美国麻醉医师协会(ASA)评分,以及术后碎石率和胆总管结石率均显著高于胆道镜组。然而,术前和术后胆囊射血分数无显著差异。单因素和多因素逻辑回归分析表明,术前胆囊壁厚度(比值比[OR]:0.540;95%置信区间[CI]:0.317 - 0.920;P = 0.023)和碎石术(OR:0.150;95% CI:0.023 - 0.965;P = 0.046)是术后胆囊射血分数的危险因素。受试者工作特征曲线下面积为0.714(P = 0.016;95% CI:0.553 - 0.854)。
应谨慎实施PCCLC策略。首先,受引流管直径限制,PCCLC仅适用于高危手术患者的小胆囊结石。其次,应严格限制碎石术的使用,以避免损害胆囊收缩功能并增加继发性胆总管结石的风险。
