Objective To evaluate the safety and efficacy of direct percutaneous Pig-tail drainage tube for intra-abdominal abscess under CT guidance.Methods Seven cases of postoperative secondary intra-abdominal abscess were implanted with direct percutaneous Pig-tail drainage tube under CT guidance.Results Nine drainage tubes were placed.Two abscesses were deep-positioned and near the spleen,pancreas,colon and other important organs,so that trocar,guide wire and dilator were used before Pig-tail drainage tube.The other 5 cases were administered direct percutaneous pig-tail drainage tube.One postoperative patient with colon cancer was operated after 3days drainage due to a large fistulae.The other 6 cases were drained for 5-14 days with an average of 9 days.Body temperatures got normal within 2 days.Six patients were healed.Conclusion The usage of CT guided direct percutaneous Pig-tail drainage tube for postoperative secondary intra-abdominal abscess is safe,minimal invasive,accurate and efficient.%目的 探讨CT引导下应用直接穿刺型猪尾巴导管组引流腹腔脓肿的疗效及安全性.方法 对7例术后继发腹腔脓肿的患者行CT引导下直接穿刺型猪尾巴导管组置管引流.结果 7例患者均一次性置管成功,共放置引流管9根.2例因脓肿位置较深,置管路径邻近脾脏、胰腺和结肠等重要器官,于应用套管针、导丝、逐步扩张器后,再置下猪尾巴导管引流；余5例应用直接穿刺型猪尾巴导管组引流.1例结肠癌术后瘘口较大,引流3d后行再次手术治疗.其余6例引流时间为5～14d,平均9d,体温在2d内恢复正常,均治愈出院.结论 CT引导下应用直接穿刺型猪尾巴导管组引流术后继发腹腔脓肿安全、微创、精确,疗效确切.
