1、内镜结合X线下金属支架置入术治疗胃十二指肠恶性梗阻32例临床研究【摘要】目的探讨经内镜结合X线下金属支架置入术治疗胃出口、十二指肠恶性梗阻的临床价值。方法取32例胃出口恶性梗阻患者,行内镜检查后经活检孔置入导丝,X线监视下置入并释放自膨式金属肠道支架。结果32例患者均成功置入支架,成功率为100.0%,其中6例采取经内镜钳道(TTS)方式释放支架,26例为经导丝直接释放支架。支架置入后内镜和透视造影检查示支架均定位准确、通畅。所有患者均存在少量出血,12例予局部喷洒孟氏液止血,效果良好。31例支架放置后1~3d梗阻症状得到缓解或消除,临床有效率为96.9
2、%,平均生存期4.8个月。1例术后1个月支架移位,1例术后2个月肿瘤向支架内浸润生长,导致梗阻复发,均予放置第2根支架后缓解。结论经内镜下放置金属支架治疗胃出口、十二指肠恶性梗阻是一种简单可行、安全有效的方法;结合X线操作具有提高置入成功率、缩短操作时间、支架定位准确以及减少患者痛苦和手术相关并发症的优点。 【关键词】胃出口梗阻;十二指肠梗阻;内镜;支架 【Abstract】ObjectiveToevaluatetheclinicalvalueofmetalstentingformalignantgastricoutletorduodena1
