目的探讨超声介入治疗肝肾囊肿一次性连接管的应用价值。方法回顾性分析超声引导治疗直径4~6cm单纯性肝、肾囊肿患者312例的临床资料,治疗过程中应用一次性连接管172例(连接管组),140例未用一次性连接管(对照组);均行超声引导下无水乙醇冲洗治疗,术后6个月超声复查,评价疗效差异。结果连接管组治愈、有效、无效分别为161例、11例、0例,对照组治愈、有效、无效分别为100例、31例、9例;两组间疗效比较差异有统计学意义(P<0.005)。结论超声引导下一次性连接管无水乙醇冲洗治疗肝肾囊肿,可以防止气体进入及穿刺针的移动,能明显提高疗效,具有重要的应用价值。

Objective To investigate the application value of one-time connection tube in the ultrasound intervention treatment of liver and kidney cysts. Methods The clinical data of 312 patients with simple hepatic and renal cysts with 4~6 cm in diameter treated under ultrasound guidance were analyzed retrospectively. In the course of treatment, one-time connection tube was used in 172 cases (connection-tube group) and not used in 140 cases (control group). All patients were treated by percutaneous injection of ethanol under ultrasound guidance. After 6 months all patients were examined by ultrasound. The differences in efficacy was evaluated by the criteria of cyst complete disappearance as cured, cyst diameter reduced more 1/2 as effective, cyst diameter reduced less 1/2, or no change as ineffective. Results In the connection-tube group, 161 patients were cured and 11 were effective. In the control group 100, 31 and 9 ones were cured, effective and ineffective,respectively. There was statistically significant difference between the two groups (P<0.005). Conclusions One-time connection tube prevents gas entering and prevents the needle moving in the ethanol irrigation treatment of liver and kidney cyst under ultrasound guidance. It improves the efficacy significantly and has important application value.
