Background Endoscopic thoracic sympathicotomy is an effective approach to the treatment of idiopathic localized hyperhidrosis, and compensatory sweating is the main reason for patient dissatisfaction. Our study discusses both the long-term outcomes of sympathicotomy and the course of compensatory sweating.

Methods Patients with palmar and/or axillary hyperhidrosis who were operated by the same surgical team between January 2008 and December 2014 were included in the study. After at least 5 years (60 months) from operation, patients were questioned about their treatment outcomes by using an original survey form.

Results Of the 137 patients included in the study, 88 (64.2%) were female and 49 (35.8%) were male. The mean time from the operation to the survey interview was 80.9 ± 14.1 (64–136) months. After operation, complaints disappeared in 95.1% of the patients, and decreased in 4.9% with palmar hyperhidrosis. Complaints completely disappeared in 12.9% and decreased in 81.7% of the patients with axillary hyperhidrosis. Ninety-seven (70.8%) of the patients described increased sweating in some parts of their body after operation but only 47 reached an uncomfortable intensity. The number of patients who regretted the operation due to the compensatory sweating was 13 (9.5%). The patients' overall scoring of the operation and procedure was calculated as 8.0 ± 2.1 (0–10 points) out of 10.

Conclusion Endoscopic thoracic sympathicotomy's long-term outcomes are also satisfactory in the treatment of palmar and axillary hyperhidrosis. Compensatory sweating may decrease over time, only a minority of patients will express regret at undergoing the treatment.

背景 内镜下胸交感神经切开术是治疗特发性局限性多汗症的有效方法，代偿性出汗是患者不满意的主要原因。我们的研究讨论了交感神经切开术的长期结果和代偿性出汗的过程。

方法 2008 年 1 月至 2014 年 12 月由同一手术团队手术的手掌和/或腋窝多汗患者纳入研究。手术后至少 5 年（60 个月）后，使用原始调查表询问患者的治疗结果。

结果 纳入研究的137例患者中，女性88例（64.2%），男性49例（35.8%）。从手术到调查访谈的平均时间为 80.9 ± 14.1 (64–136) 个月。术后95.1%的患者主诉消失，4.9%的患者出现手掌多汗症状。12.9%的腋窝多汗患者主诉完全消失，81.7%的患者主诉减少。97 名 (70.8%) 的患者描述了术后身体某些部位出汗增加，但只有 47 人达到了不舒服的强度。因代偿性出汗而后悔手术者13例（9.5%）。患者对手术和程序的总体评分计算为 8.0 ± 2.1（0-10 分）（满分 10 分）。

结论 内镜下胸交感神经切开术治疗手腋多汗症的远期疗效也令人满意。代偿性出汗可能会随着时间的推移而减少，只有少数患者会对接受治疗表示遗憾。
