GUT:内窥镜下黏膜治疗不同方法的优势比较!

2017-10-15 MedSci MedSci原创

近期,一项发表在杂志gut上的研究旨在比较用于切除大于20mm的大的无蒂横向扩张的结肠直肠病变(LSL)的内窥镜粘膜下剥离术(ESD)和大面积内窥镜粘膜切除术(WF-EMR)的成本效益。此项研究在为期18个月的时间内使用决策树模型进行了增量成本效益分析。比较了以下策略:使用WF-EMR,通用ESD(U-ESD)和选择性ESD(S-ESD)用于含有粘膜下侵袭性癌症(SMIC)的高度可疑的病变,其余病

近期,一项发表在杂志gut上的研究旨在比较用于切除大于20mm的大的无蒂横向扩张的结肠直肠病变(LSL)的内窥镜粘膜下剥离术(ESD)和大面积内窥镜粘膜切除术(WF-EMR)的成本效益。

此项研究在为期18个月的时间内使用决策树模型进行了增量成本效益分析。比较了以下策略:使用WF-EMR,通用ESD(U-ESD)和选择性ESD(S-ESD)用于含有粘膜下侵袭性癌症(SMIC)的高度可疑的病变,其余病变使用WF-EMR。来自大型西方队列和文献的数据用于模型分析。有效性定义为每1000例患者中避免手术的次数。同时提出了避免手术的增量成本并进行了灵敏度和情景分析。

最终,此项研究共分析1765例患者中的1723例病变。SMIC和低分险SMIC的流行率分别为8.2%和3.1%。SMIC内镜病变评估的灵敏度和特异度分别为34.9%和98.4%。 S-ESD是最便宜的策略,并且通过每1000例病例预防19次额外手术也证明了其比WF-EMR更有效。在S-ESD战略中,需要采取43项ESD程序。 与S-ESD相比,U-ESD可以预防额外的13次手术,这些手术的增量成本为210112美元。在高风险直肠病变中,U-ESD只具有成本效益。

此项研究结果表明:S-ESD是首选治疗策略。但是,每1000个LSL只需要43个ESD。WF-EMR对大多数LSL仍然是一个有效和安全的治疗选择。

利用显微镜中耳整复术已经有几十年的历史了。然而,自从20世纪70年代内窥镜开始用于中耳手术,内窥镜中耳整复术获得了越来越多的关注。最近,有研究人员就内窥镜和显微镜中耳整复术带有或者不带有听骨形成术,进行了每种疗法的潜在优势、劣势和效果的研究。该回顾性的研究包括了126名患有慢性中耳炎的病人,并且在2013年到2015年在医院接受了中耳整复术治疗。术后的临床跟踪调查至少3个月。另外,研究人员在手术前
