探讨猪尾引流管在肝脓肿引流术后堵塞的原因和处理方法。

回顾性分析2016年4月至2017年1月空军军医大学唐都医院收治的3例复杂肝脓肿患者临床资料。患者均签署知情同意书，符合医学伦理学规定。例1男，84岁；例2女，57岁；例3女，50岁。3例穿刺放置猪尾引流管后引流管堵塞，遂实施引流管旋转技术，顺时针或逆时针旋转。

多次旋转引流管后头端松动，引流管疏通，引流出坏死组织。例1和例3在旋转猪尾管后出现一过性轻中度发热不适，自行缓解。3例患者在旋转引流管并疏通后出现少量出血，Hb无明显变化。3例患者引流管通畅后，发热缓解，均治愈出院，术后1年复查无复发。

对于难以疏通的肝脓肿猪尾引流管堵塞，可使用旋转松动引流管的方法。

To investigate the causes and treatments for the congestion after pig-tail catheter drainage of liver abscess.

Clinical data of 3 patients with complicated liver abscess admitted to Tangdu Hospital of Air Force Military Medical University from April 2016 to January 2017 were retrospectively analyzed. The informed consents of all patients were obtained and the local ethical committee approval was received. Case 1, male, aged 84 years; Case 2, female, aged 57 years; Case 3, female, 50 years. The pig-tail catheter was clogged after being placed in 3 patients for drainage and the drainage catheters were therefore rotated clockwise or counter clockwise.

After multiple rotations, the head end of drainage catheter was loosened and unclogged and necrotic tissues was drained out. Mild or moderate fever was observed in cases 1 and 3 after rotating the pig-tail catheter, which was relieved spontaneously. 3 patients presented with mild bleeding after rotating the catheter and no significant change was noted in Hb. After the drainage catheter was unobstructed, the fever was relieved and all were cured and discharged. No recurrence was observed at postoperative 1 year.

For the intractable congestion of pig-tail catheter in liver abscess patients, rotating and loosening the catheter can bea good appoach.
