摘要/Abstract

摘要： 目的分析采取内镜下乳头括约肌小切开术(EST)联合球囊扩张术(EPBD)治疗非扩张性肝外胆管结石患者的疗效及其血清淀粉酶(AMS)和环氧合酶-2(COX-2)水平的变化。方法 2017年7月～2019年5月我院肝胆外科收治的120例非扩张性肝外胆管结石患者,其中60例接受EST治疗,另60例接受EST联合EPBD治疗。结果在术后7 d,联合组外周血白细胞(WBC)计数为(7.8±1.4)×10⁹/L,与对照组的(7.6±1.2)×10⁹/L比,差异无统计学意义(P>0.05),血清COX-2水平为(45.3±11.7)ng/mL,与对照组的(49.6±15.2)ng/mL比,差异无统计学意义(P>0.05),血降钙素原(PCT)水平为(0.4±0.3)μg/L,与对照组的(0.4±0.2)μg/L比,差异无统计学意义(P>0.05),C反应蛋白(CRP)水平为(8.7±2.9)mg/L,与对照组的(8.4±3.2)mg/L比,差异无统计学意义(P>0.05),肿瘤坏死因子-α(TNF-α)水平为(0.5±0.2)ng/mL,与对照组的(0.5±0.2)ng/mL比,差异无统计学意义(P>0.05),血清AMS水平为(60.1±16.7)U/L,与对照组的(58.7±15.3)U/L比,差异无统计学意义(P>0.05);术后,联合组并发症发生率为25.0%,与对照组的31.7%比,差异无统计学意义(P>0.05);联合组一次取石成功率为98.3%,显著高于对照组的86.7%,机械碎石率为5.0%和结石复发率为3.3%, 则均显著低于对照组(分别为16.7%和15.0%,P<0.05)。结论 EST联合EPBD治疗非扩张性肝外胆管结石患者能一次取净结石,而在EPBD的协助下不会加剧机体炎症反应,降低术后结石复发,值得临床进一步研究。

Abstract: Objective The purpose of this study was to investigate the combination of endoscopic sphincterotomy (EST) and endoscopic papillary balloon dilation (EPBD) in treatment of patients with non-expansive extrahepatic bile duct stones. Methods The clinical data of 120 patients with non-expansive extrahepatic bile duct stones were admitted to the Department of Hepatobiliary Surgery in our hospital between July 2017 and May 2019, and were randomly divided into control (n=60) and observation group (n=60), underwent EST or EST and EPBD combination surgery. Results 7 days after the operation, the white blood cell (WBC) counts in the observation group was (7.8±1.4) ×10⁹/L, not statistically significantly different as compared to (7.6±1.2) ×10⁹/L in the control (P>0.05), serum cyclooxygenase-2 level in the observation group was (45.3±11.7) ng/mL, not much different to (49.6±15.2) ng/mL, blood procalcitonin (PCT) level was (0.4±0.3) g/L, not significantly different to (0.4±0.2) g/L, serum C-reactive protein (CRP) level was (8.7±2.9) mg/L, not significantly different to (8.4±3.2) mg/L, serum tumor necrosis factor-α (TNF-α) level was (0.5±0.2) ng/mL, not significantly different to (0.5±0.2) ng/mL, blood amylase level was (60.1±16.7) U/L, not significantly different to (58.7±15.3) U/L in the control (P>0.05); the total incidence of complications in the observation group was 25.0%, not statistically significantly different compared with 31.7% (P>0.05) in the control; the successful rate of primary stone removal in the observation group was 98.3%, significantly higher than 86.7% in the control, and the mechanical gravel rate was 5.0% and the stone recurrence rate was 3.3%, both significantly lower than 16.7% and 15.0%, respectively, (P<0.05) in the EST-treated patients.Conclusion The combination of EST and EPBD in the treatment of patients with non-dilated extrahepatic bile duct stones has a higher successful rate of one-step stone extraction, with less postoperative stone recurrence, which warrants further clinical investigation.
