超声内镜引导经胃内引流术治疗胰腺假性囊肿误吸的预防

Prevention of wrong absorption of pancreatic pseudocyst using guided transmural drainage under endoscopic ultrasonography

摘要:

目的??探讨如何预防在超声内镜（EUS）引导下经胃内治疗胰腺假性囊肿引起的误吸。方法?对该院所做的EUS引导下经胃内引流胰腺假性囊肿的资料进行回顾性分析。结果?16例胰腺假性囊肿患者，经EUS引导胃内穿刺放置内支架引流成功16例，穿刺引流操作成功率为100.0%。囊肿完全吸收16例，治愈率100.0%。穿刺后囊液反流导致误吸2例，发生率为12.5%。3例患者通过内镜拔出引流支架，另外13例患者支架自行脱落排出。结论?头高脚低位、精细操作及食管套管可以防止EUS穿刺后胰腺假性囊肿囊液误吸入气管。

Abstract:

Objective?To discuss how to preven wrong absorption of pancreatic pseudocyst using guided transmural drainage under endoscopic ultrasonography.?Methods?Retrospectively analyzed the clinical data of patients with pancreatic pseudocysts underwent operations of Endoscopic ultrasonography guided transmural drainage.?Results?16 cases of pancreatic pseudocysts were finished with guided transmural drainage under endoscopic ultrasonography using needling to place bypass grafting with successful rate 100.0% of guided transmural drainage by needling. After needling, 2 cased happened regurgitation which led to wrongly absorbed, rate of occurrence is 12.5%. Generally, pancreatic pseudocysts of 16 cases disappeared completely with cure rate 100.0%. From above, stents were pulled out by endoscope in 3 cases while stents were removed voluntarily in another 13 cases.?Conclusion?Dorsal elevated position, detailed operation and esophageal annular tubes can effectively prevent wrong absorption of guided transmural drainage under endoscopic ultrasonography of pancreatic pseudocysts.
