目的 探讨内镜联合X线监视下支架植入治疗中晚期食管癌恶性梗阻的临床疗效。方法 选择2010年6月—2017年10月在内蒙古呼和浩特市第一医院中晚期食管癌恶性梗阻的67例患者,根据患者意愿分为内镜联合X线监视下支架植入组(联合组, n ...目的 探讨内镜联合X线监视下支架植入治疗中晚期食管癌恶性梗阻的临床疗效。方法 选择2010年6月—2017年10月在内蒙古呼和浩特市第一医院中晚期食管癌恶性梗阻的67例患者,根据患者意愿分为内镜联合X线监视下支架植入组(联合组, n =35)和X线监视下放置支架组(普通组, n =32)。观察比较两组患者术前及术后1~3个月的生活质量和吞咽困难指数变化情况,观察患者的术后并发症并及时对症治疗;统计术后患者的生存期与存活率,并采用生存质量核心问卷(QLQ-C30)和食管癌专用量表(OES-18)调查患者的生活质量。结果 两组患者均一次性成功植入支架,成功率达100%,吞咽困难立刻改善明显,两组评分由联合组和普通组的(3.3 ±0.6)和(3.2 ±0.7)分改善为(1.0±03)分,1周后的评分均改善为0分。两组患者术中、术后无大出血和穿孔的发生,均有不同程度的胸骨后疼痛和不适,大多数均不需特殊处理。联合组患者的再阻塞率、生存时间、生存质量明显高于普通组患者( P <0.05),联合组的再阻塞率明显低于普通组患者( P <0.05);但两组间支架移位率无统计学差异( P 〉0.05)。结论 应用内镜和X线双重定位下植入支架治疗不愿或不能手术切除的中晚期食管癌患者,具有创伤小、安全、定位准确等特点,能迅速缓解患者的症状,提高生存质量,延长生存时间,具有良好的临床应用价值。展开更多
