1、金属支架治疗恶性幽门梗阻的内镜下置入技术探讨张宁张楠于杰毛建新冯国芹青岛市第三人民医院内窥镜中心266041【摘要】目的探讨金属支架治疗恶性幽门梗阻在内镜下置入的临床技术。方法共有24例患者行内镜下金属支架置入,所有患者均为晚期胃窦部或幽门管癌并有幽门梗阻,不能进食和进食后呕吐。根据支架置入和疗效分为支架置入成功和临床成功。结果20例患者置入1个支架,3例患者置入2个支架。支架置入成功23例(95.8%)。1例不成功是因支架置入器不能送入狭窄部位。支架置入后有19例患者至少能进软食,无呕吐症状,临床成功率
2、为79.2%。支架置入过程中无严重并发症及死亡病例。支架置入后并发症的发生率为17.4%(共4例),1例是置入支架移位,3例为置入支架梗阻。结论对不能手术的胃癌所至幽门梗阻的姑息治疗,内镜下幽门置入金属支架的技术是可行的。该方法安全有效,创伤小,成功率高。【关键词】置入技术;金属支架;恶性幽门梗阻;内镜ThestudyofendoscopicallyplacedprocedureofmetallicstentsformalignantgastricoutletobstructionZHANGNing,ZH
