目的比较腹腔镜胆囊切除联合胆总管探查术（LC＋LCBDE）与内镜下Oddi括约肌切开取石联合腹腔镜胆囊切除术（EST＋LC）治疗胆囊结石合并肝外胆管结石的临床疗效。 方法回顾性分析45例行LC＋LCBDE及60例行EST＋LC患者的临床资料，观察2组在单次结石清除率、中转手术率、手术并发症、住院时间等指标方面的效果。 结果2组患者的基线资料相近，无手术死亡病例；2组术后并发症发生情况的差异无统计学意义（P＞0.05）；LC＋LCBDE组单次治疗成功率高于EST＋LC组，而住院时间及中转手术率则短于或低于EST＋LC组（P＜0.05）。 结论LC＋LCBDE是治疗胆囊结石合并肝外胆管结石患者安全有效的方法。
ObjectiveTo conduct a Meta-analysis to determine the clinical effect of protocol biopsy (PB)-monitored therapy after renal transplantation.MethodsPubMed, Embase, Cochrane Library, Chinese National Knowledge Infrastructure, Wanfang Standards Database and VIP Database for Chinese Technical Periodicals were searched for trials comparing the efficacy of timely intervention under PB surveillance with the conventional treatment. The quality of included studies was assessed and Meta-analysis was conducted by RevMan 5.3 software.ResultsSix randomized controlled trials met our inclusion criteria, including 698 cases. No significant difference was found between the PB group and the control group in 1-year [relative risk (RR)=0.99, 95% confidence interval (CI) (0.97, 1.01), P=0.39] and 2-year recipient survival rate [RR=1.00, 95%CI (0.97, 1.02), P=0.72]. Graft survival rate after 1 year [RR=1.01, 95%CI (0.99, 1.04), P=0.29] and 2 years [RR=1.02, 95%CI (0.99, 1.06), P=0.19] were also statistically similar. No statistical difference was found in glomerular filtration rate between the two groups [mean difference (MD)=0.45 mL/(min·1.73 m2), 95%CI (–3.77, 4.67) mL/(min·1.73 m2), P=0.83]. Renal function of PB group, monitored by serum creatinine, was superior to the control group [MD=–0.46 mg/dL, 95%CI (–0.63, –0.29) mg/dL, P<0.000 01]. No statistical difference was found in infection between the two groups [RR=1.23, 95%CI (0.69, 2.19), P=0.48].ConclusionsOur study did not suggest PB for every kidney transplantation recipient. However, long-term randomized controlled trials with larger sample size would be necessary to determine whether PB was effective for specific populations.
