自制气囊引流管行结肠旁路引流治疗医源性结肠穿孔

Clinical application of self-made drainage tube with balloon for iatrogenic colonic perforation

目的探讨采用自制气囊引流管行结肠旁路引流在医源性结肠穿孔患者中的临床应用价值。方法回顾性分析2009年1月至2011年3月间哈尔滨医科大学附属第二医院消化内科采用自行设计的结肠气囊引流管治疗的8例医源性结肠穿孔患者的临床资料。所有结肠穿孔在内镜下金属夹和（或）尼龙绳缝合后。将自制气囊引流管在内镜直视下留置于肠腔内．引流管前端气囊充气后固定于穿孔部位的近口侧．后端固定于患者臀部并行持续引流肠液及粪便。结果8例患者气囊引流管均成功放置并引流通畅．穿孔均完全愈合．无中转外科手术病例。气囊引流管旁路引流时间3-10（平均7．6）d，1例患者术后3d复查结肠镜，发现气囊导管移位，予以内镜下校正。所有8例患者气囊引流管均顺利拔除。拔除后肠壁气囊固定部位无溃疡穿孔发生。术后随访12-36（平均25．4）个月，全组患者术后无慢性肠瘘、粘连性肠梗阻或腹腔感染等并发症发生。结论应用自制气囊引流管行结肠旁路引流治疗医源性结肠穿孔简单、安全并可靠。

Objective To investigate the clinical efficacy of colonic bypass drainage by self-made drainage tube with balloon for iatrogenic colonic perforation. Methods A retrospective analysis of 8 patients with iatrogenetic colonic perforations from January 2009 to March 2011 was performed. Self-made drainage tubes with balloon were placed in the bowel lumen endoscopically after perforations were closed with endoclips or endoloops under endoscope. The inflatable balloon at the front-end of the tube was fixed at the mouth side of colonic perforation to achieve continuous drainage of stool and intestinal juice. Results Endoscopic bypass continuous drainage by using self-made drainage tube with balloon was successfully carried out in all the 8 patients. All the perforations healed and no surgical intervention required. Bypass drainage continued for 3-10 days （mean 7.6 days）. One patient received colonoscopy 3 days after the procedure, and displacement of the drainage tube was noticed requiring endoscopic adjustment. All the drainage tubes were removed uneventfully, and no ulceration or perforation occurred at balloon fixed site after removal. After follow up ranging from 12 to 36 months, no chronic fistula, adhesive obstruction, or abdominal infection occurred. Conclusion Colonic bypass drainage by selfmade drainage tube with balloon for iatrogenic colonic perforation is simple, feasible, safe and reliable.
