Br J Surg:神经刺激能不能治疗难治性便秘?

开放性研究报告了骶神经刺激治疗难治性便秘的良好效果。在这里,通过一项双盲交叉试验评估其疗效。至少符合以下两个标准的患者纳入研究:每周排便不到三次;超过25%的尝试都在竭力疏散;或超过25个以上的场合感觉到不完全疏散。治疗的反应被定义为每周至少三次排便和/或症状改善超过50%。对最初三周周围神经评估响应者提供永久植入脉冲发生器,随机分配到两个间隔8周的积极或虚假刺激的交叉设计中。在两个试验期结束时,

开放性研究报告了骶神经刺激治疗难治性便秘的良好效果。在这里,通过一项双盲交叉试验评估其疗效。

至少符合以下两个标准的患者纳入研究:每周排便不到三次;超过25%的尝试都在竭力疏散;或超过25个以上的场合感觉到不完全疏散。治疗的反应被定义为每周至少三次排便和/或症状改善超过50%。对最初三周周围神经评估响应者提供永久植入脉冲发生器,随机分配到两个间隔8周的积极或虚假刺激的交叉设计中。在两个试验期结束时,患者接受积极的刺激,直到1年时进行最终评价。

36例患者(女性34例;平均年龄(SD)45(14)岁)行外周神经评价。二十例响应者接受了永久性刺激物。极或虚假刺激组分别有12/20例和11/20例患者出现阳性反应(P = 0•746)。5例患者发生设备相关的疼痛,3例患者发生伤口感染或血肿。1年后,20例植入装置患者中的11例持续作出回应。刺激对结肠传输时间无显着影响。

这些结果不支持,对临时神经刺激有反应的患者,永久植入脉冲发生器治疗难治性便秘。

随机双盲研究:枕部神经刺激缓解药物治疗无效偏头痛

美国头痛学会年会上报告的一项针对偏头痛药物治疗无应答患者的随机双盲试验显示,枕部神经刺激可使慢性偏头痛缓解。 该研究中,费城杰佛逊头痛中心的研究者纳入125例每月至少15天有头痛发作、至少3种预防性药物治疗失败并发生中度头痛相关障碍的慢性、难治性偏头痛患者。其疼痛必须在10 cm视觉模拟量表中标注在6 cm以上,且疼痛局限于头后部或起源于颈部区域。不要求患者既往对枕部神经阻滞有应答,Silbers
