骶神经调节术治疗顽固性便秘疗效观察

目的：观察骶神经调节术（SNM）治疗顽固性便秘的临床效果。方法第四军医大学西京消化病医院消化外科于2013年1月至2014年1月期间，采用骶神经调节测试系统经皮穿刺，刺激第3骶神经根，治疗7例复杂便秘患者，其中4例患者既往进行过至少1次的便秘手术。通过排粪日记、Cleveland便秘评分及视觉模拟评分（VAS）进行疗效评价。结果7例患者在接受体外临时测试治疗后，便秘症状均明显改善。其中6例接受永久性骶神经调节器植入术，围手术期未见并发症。术后随访中位时间4（2～12）月，6例患者的每周排粪次数由治疗前（0．6±0．5）次／周，增加到（8．0±2．5）次／周（P＜0．01）；排粪时间从（22．9±11．5） min减少到（3．7±0．8） min（P＜0．01）；Cleveland便秘评分从（24．6±4．2）分下降到（9．0±0．9）分（P＜0．01）；VAS评分从（8．1±0．9）分增加到（82．5±5．2）分（P＜0．01）。结论 SNM是治疗顽固性便秘的一种微创而安全有效的新方法。

Sacral neuromodulation in the treatment of intractable constipation

Objective To assess the efficacy of sacral neuromodulation （SNM） in patients with intractable constipation. Methods A total of 7 patients with intractable constipation were treated with pereutaneous test stimulation of the S3 nerve root and were assessed by sacral never stimulation system in our department from January 2013 to January 2014. Four of these 7 patients received operation for constipation before. The efficacy was assessed by bowel habit diary, clinic constipation scores, subjective questionnaire and clinical signs. Results The constipation symptoms were improved significantly in all the 7 patients. The frequency and volume of defecation per week were increased obviously, and the average urine was increased. Six patients underwent permanent implantation of the SNS system. After a median 4 months follow-up, the defecation frequency increased from 0.6 ±0.5 to 8.0 ±2.5 per week （P〈0.01）, and the defecation time decreased from （22.9 ±11.5） to （3.7 ±0.8） min （P〈0.01）. The Cleveland clinic constipation score decreased from 24.6±4.2 to 9.0±0.9 （P〈0.01）, and the visual analogue scale（VAS） score increased from 8.1±0.9 to 82.5±5.2（P〈0.01）. Conclusion SNM is a clinically efficacious, minimally invasive and safe new technique, which offers an alternative treatment for the patients with intractable constipation resistant to conservative treatment , especially for the patients refractory to traditional operations.
