内镜超声引导下经胃穿刺覆膜金属支架引流胰腺假性囊肿的初步临床研究

目的评价临床应用胆道覆膜自膨式金属支架引流胰腺假性囊肿的有效性、可行性和安全性。方法回顾分析2013年9月至2014年5月在长海医院接受内镜超声（EUS）引导下经胃胰腺假性囊肿全覆膜自膨式金属支架引流的11例患者病例和随访资料。引流方法采用EUS引导下经胃壁穿刺至囊腔，置入导丝，用囊肿切开刀进行针道扩张，置入金属覆膜支架引流。术后定期随访，囊肿消失后拔除支架。评价操作成功率、治愈成功率、并发症发生率。结果11例患者均完成囊肿穿刺、全覆膜金属支架置入引流术，手术成功率为100％，2例患者并发感染，1例患者发生支架移位，无出血、穿孔、死亡病例。其中7例已完成支架拔除术，囊肿均完全消失。结论EUS引导下经胃穿刺胆道覆膜金属支架引流胰腺假性囊肿手术成功率、治愈率高，并发症发生率较低。

Clinical evaluation of fully covered self-expanding metal stent for endosonograph-guided transgastric pancreatic pseudocyst drainage

Objective To evaluate technical efficacy, feasibility and safety of a fully covered self- expanding metal stent for EUS-guided transgastric pancreatic pseudocyst drainage. Methods Data of a total of 11 patients who received EUS-guided transgastric pancreatic pseudocyst drainage with a covered self-ex- panding metal stent at Changhai Hospital from September 2013 to May 2014 were retrospectively studied. The manipulative success rates, curative success rates and complication rates were evaluated. Results All 11 patients were treated by EUS-guided transgastric pancreatic pseudocyst drainage with fully covered self-ex- panding metal stents successfully,with success rate of 100%. Two patients developed infection and displace- ment occurred in 1 patient. There was no hemorrhage, perforation or death. Stents were removed in 7 pa- tients and the pseudocysts vanished. Conclusion Endosonography-guided transgastric pancreatic pseudocyst drainage using a fully covered serf-expanding metal stent can be accomplished with high technical and clinical success rate and low rate of complications.
