PURPOSE This study aimed to evaluate the efficacy, safety, and follow-up results of the percutaneous treatment of cystic echinococcosis (CE) patients with giant hepatic cysts (at least one diameter > 10 cm). METHODS Between January 2013 and 2018, 31 CE patients with 34 giant cysts classified as CE1 or CE3a (Gharbi type 1 or 2) according to the World Health Organization criteria and treated with the catheterization technique were analyzed retrospectively. RESULTS Thirty-four giant hepatic cysts were treated using the catheterization technique. Technical success was 100%. One procedure was sufficient for 27 of these cysts, while six patients underwent a second procedure due to recurrence, recollection or complications; one did not accept a repeat procedure and decided to refer to surgery due to pain. Ten (29%) major complications developed. The overall clinical success was 97%. The mean follow-up period was 20 months (5-61 months), and the total reduction in the cyst volume was 92%. CONCLUSION The catheterization technique is effective in treating giant CE with acceptable complication rates. LEVEL OF EVIDENCE Level 4, Clinical Investigation.

经皮肝巨囊性球虫病的治疗：CE1和CE3a患者的导尿术。

目的本研究旨在评估经皮治疗巨大肝囊肿（至少一个直径> 10 cm）的囊性棘球cc虫病（CE）患者的疗效，安全性和随访结果。方法回顾性分析2013年1月至2018年1月根据世界卫生组织标准分类为CE1或CE3a（Gharbi 1型或2型）的34例巨大囊肿的31例CE患者。结果采用导管技术治疗了34例巨大肝囊肿。技术成功率为100％。一种方法足以治疗其中的27个囊肿，而六名患者由于复发，回忆或并发症而进行了第二种方法。一个人不接受重复手术，由于疼痛而决定转诊。发生了十项（29％）重大并发症。总体临床成功率为97％。平均随访期为20个月（5-61个月），囊肿体积的总减少为92％。结论导尿术可有效治疗巨大的CE，并具有可接受的并发症发生率。证据级别4级，临床研究。
