The aim of this study was to determine the effectiveness of ultrasound-guided interventional therapy in the treatment of postoperative recurrent chocolate cysts. The 198 patients enrolled in this study were divided into three groups. In group 1, the saline washing group, the cavity of the cyst was washed thoroughly with warm saline. In group 2, the ethanol short-time retention group, after washing with saline, the cyst was injected with 95% ethanol with a volume of half of the fluid aspirated from the cyst. Ten minutes later, the rest of the ethanol was aspirated. In group 3, the ethanol retention group, the procedures were the same as with the ethanol short-time retention group, except that 95% of the ethanol was retained in the cyst. An ultrasound examination was performed in the third, sixth and 12th months after therapy. The chocolate cyst cure rate was significantly higher in the ethanol retention group (96%, 66/69) than in the ethanol short-time retention group (82%, 56/68) and no case was cured in the first group (saline washing). We conclude that ultrasound-guided injection and 95% ethanol retention are an effective therapy for the treatment of postoperative recurrent chocolate cysts.
本研究旨在探讨超声引导介入治疗在术后复发巧囊中的疗效。本研究共纳入 198 例患者，分为三组。第 1 组（盐水冲洗组），囊腔用温盐水彻底冲洗；第 2 组（乙醇短时间保留组），盐水冲洗后，向囊内注入 95%乙醇，注入量为吸出囊液的一半，10 分钟后抽吸剩余乙醇；第 3 组（乙醇保留组），操作与乙醇短时间保留组相同，仅将 95%乙醇保留在囊内。治疗后第 3、6、12 个月行超声检查。乙醇保留组巧克力囊肿治愈率（96%，66/69）明显高于乙醇短时间保留组（82%，56/68），而第 1 组（盐水冲洗组）无 1 例治愈。结论：超声引导下注射 95%乙醇保留是治疗术后复发巧囊的有效方法。
