Gut:横向扩张大肠病变中内镜治疗的成本效益比较研究

2017-11-13 zhangfan MedSci原创

研究认为,选择性内镜黏膜下剥离术是较优的大型直肠病变治疗手术方法,广角内镜下黏膜切除术为次优治疗方法,而常规内镜黏膜下剥离术仅在高危病变患者中表现出较好的成本效益

近日研究人员比较了内镜黏膜下剥离术(ESD)和广角内镜下黏膜切除术(WF EMR)对>20mm的固着和横向扩张的大肠病变(LSLs)治疗的成本效益差异。

研究随访18个月,考察的治疗手段包括WF-EMR、常规ESD(U-ESD)和选择性ESD (S-ESD,粘膜下浸润癌疑似患者[SMIC])。治疗的有效性通过每1000名病例中避免二次手术的患者数进行考察。

1765名患者以及1723个病变参与研究。SMIC以及低风险SMIC率为8.2%和3.1%。内镜下病变评估对SMIC确诊的敏感性为34.9%,特异性为98.4%。研究发现,S-ESD是最廉价的治疗策略,但有效性高于WF-EMR,每1000患者中可以减少19例额外手术,S-ESD手术后发生了43起额外ESD。U-ESD仅在直肠高危病变患者中表现出较好的性价比,对于这部分患者U-ESD相比S-ESD可以减少13起二次手术,避免$210 112手术费用。

研究认为,选择性内镜黏膜下剥离术是较优的大型直肠病变治疗手术方法,广角内镜下黏膜切除术为次优治疗方法,而常规内镜黏膜下剥离术仅在高危病变患者中表现出较好的成本效益。
