Large-dose Absolute Ethanol Sclerotherapy with Ultrasound-guided Catheterization for Huge Liver Cyst

目的探讨超声引导下置管大剂量无水乙醇硬化治疗巨大肝囊肿的疗效和安全性。方法 2001年5月～2011年5月,巨大肝囊肿24例,均为单发囊肿,直径102～180 mm,先在超声引导下穿刺囊肿并置入引流管,通过引流管抽尽囊液,使用大剂量无水乙醇注入囊腔硬化治疗,再用生理盐水冲洗囊腔,保留导管引流4～7天。结果治疗后3、6个月囊肿缩小率分别为(68.8±13.2)%、(86.3±12.4)%,术后12个月24例囊肿均完全消失,囊肿治愈率100%(24/24)。囊肿消失后随访2～5年,平均3年,无复发。结论该方法治疗巨大肝囊肿安全、微创,效果确切。

Objective To study the efficacy and safety of large-dose absolute ethanol sclerotherapy with ultrasound-guided catheterization. Methods From May 2001 to May 2011, 24 patients with huge single liver cyst （ 102 - 180 mm in diameter） , received treatment in our hospital. Under the guidance by uhrasonography, we punctured the cyst and inserted a catheter to drain the cystic fluid, and then, absolute ethanol sclerotherapy was performed. After the procedure, we used P.S. to wash the cystic cavity, and a drainage catheter was kept for 4 to 7 days afterwards. Results The cysts were reduced by a mean of （68.8 ＋ 13.2） % in 3 months after the procedure, （ 86.3 ± 12.4） % in 6 months, and 100% in 12 months. The patients were followed up for a mean of 3 years （2 - 5 years） ,no recurrence was found. Conclusion It is safe, minimally invasive and effective to treat huge liver cyst by large-dose absolute ethanol sclerotherapy with ultrasound-guided catheterization.
