T4交感神经干切断术治疗原发性手足多汗症对足汗的影响

目的：观察胸腔镜下T4交感神经干切断术治疗原发性手足多汗症后对足汗的影响。方法：收集2009年6月至2014年5月接受胸腔镜下双侧T4交感神经干切断术治疗原发性手汗症患者28例。在手术前后患者完成有关多汗症的调查问卷并予以评分。术后1个月至半年连续随访足汗症状缓解情况。结果：患者均顺利完成双侧同期胸腔镜下T4交感神经干切断术。术后所有病例手汗症状完全缓解，随访期间未发现手汗症复发。术后1个月足汗症状缓解率28.6%(8/28)，但随后足汗的症状再次复发；术后6个月，无患者表现足汗的症状缓解。27例(96.4%)患者对于手术效果非常满意，1例(3.6%)患者认为手术效果比较满意，没有患者不满意或后悔接受手术治疗。结论：胸腔镜下T4交感神经干切断术虽然早期缓解部分原发性手足多汗症患者足汗症状，但效果不能长久维持；不能用该术式来治疗单纯的足汗症。

Effect of T4 thoracoscopic sympathectomy on plantar hyperhidrosis in patients with primary palmoplantar hyperhidrosis

Objective: To evaluate the effect of video-assisted thoracoscopic sympathectomy at the T4 level on plantar hyperhidrosis in the treatment of palmoplantar hyperhidrosis. Methods: The clinical data of 28 patients with primary palmoplantar hyperhidrosis, who were admited in our hospital from June 2009 to May 2014, was analyzed. All patients were qualified to bilateral thoracoscopic transaction of the sympathetic chain at the thoracic level T4. Patients completed a self-administered hyperhidrosis questionnaire and scoring before and after procedure. Follow-up data were obtained at 1 and 6 months after the surgery. Results: Endoscopic thoracic sympathectomy at the thoracic level T4 was performed successfully for all cases. Palmar hyperhidrosis was completely alleviated after the operation and no recurrence was observed during follow-up. The ratio for initial improvement of plantar hyperhidrosis was 28.6% (8/28) at 1 month after the surgery followed by a recurrence of plantar hyperhidrosis. No case continued to show the improvement of palmoplantar hyperhidrosis at 6 months after the sympathectomy. Twenty-seven patients (96.4%) were very satisfied with the outcome of the operation, 1 patient (3.6%) satisfied and no patient regretted the surgical procedure. Conclusion: T4 thoracoscopic sympathectomy could initialliy alleviate plantar hyperhidrosis in some patients with palmoplantar hyperhidrosis, but the improvement was not sustained over a long period. It could not be used to treat plantar hyperhidrosis.
