[背景 ]非寄生虫性肝囊肿是无症状小囊肿 ,无需治疗 ,有压迫症状或出现并发症者 ,应采用手术治疗 .[病例报告 ]1999年 4月行巨大非寄生虫性肝囊肿内引流术 1例 ,术后因内引流不畅、肠内容物反流淤积 ,内引流术失败 .进行第二次手术时利用粗大胶皮引流管行体外引流术 ,术后近 4周囊肿闭缩治愈 .[讨论 ]非寄生虫性肝囊肿通常术式有囊肿开窗术、切除术、内引流术等 .内引流术适用于囊肿体积较大、切除困难者及囊液含有胆汁者 ,该术式基本要求为吻合口要大、位置要低、Y臂长 30～ 6 0cm .本病例吻合口较小且Y臂短 ,导致内引流术失败 [Background] Non-parasitic hepatic cysts are asymptomatic small cysts, requiring no treatment, with oppression or complications, and should be treated surgically. [CASE REPORT] A large, non-parasitic hepatic cyst drain was performed in April 1999 Surgery in 1 case, due to poor drainage after surgery, intestinal contents of the deposition of reflux, the drainage failed. The second operation using a thick plastic drainage tube drainage in vitro surgery, closed after 4 weeks of cyst closure cure. [Discussion] Non-parasitic hepatic cysts usually have cyst fenestration, resection, internal drainage, etc. Internal drainage is suitable for patients with large cysts, difficult to remove and cystic fluid containing bile Requirements for anastomotic should be large, the position is low, Y arm length 30 ~ 60cm. The case of anastomotic Smaller and shorter Y arm, resulting in the failure of the internal drainage
