ObjectiveCompensatory sweating is the most common and troublesome complication of thoracodorsal sympathectomy. Whether the magnitude of compensatory sweating is related to the extent of sympathectomy is unclear. We investigated the association between the extent of sympathectomy and the occurrence and severity of compensatory sweating after endoscopic transthoracic sympathectomy for upper limb hyperhidrosis.MethodsFrom September 1992 to June 2000, data from patients undergoing thoracoscopic sympathectomy to treat primary upper limb hyperhidrosis in our department were prospectively collected. Routine follow-up with clinical examination was performed at 1, 3, and 6 months for the first postoperative year and every year thereafter. Late follow-up (February 2001) was with a standardized questionnaire by mail or telephone concerning compensatory sweating and patient satisfaction. Associations between the extent of sympathectomy and the occurrence and severity of compensatory sweating were analyzed with logistic regression and adjusted for age, gender, and relevant confounding factors.ResultsTwo hundred sixty-eight sympathectomies were consecutively performed in 134 patients (99 female, 35 male; mean age, 27.8 +/- 6.7 years). In the 84 patients with palmar hyperhidrosis, eight underwent T1-T2 resection, four T1-T3 resection, eight T2-T3 resection, and 64 T2-T4 resection. In the 43 patients with palmar and axillary hyperhidrosis, eight underwent T1-T5 resection and 35 T2-T5 resection. The seven patients with isolated axillary hyperhidrosis underwent T3-T5 sympathectomy. No deaths occurred; one conversion for bleeding, one permanent Horner's syndrome, and six minor complications did occur. The initial cure rate was 99.2%. The initial satisfaction rate was 97%. The mean follow-up period was 44.3 months (range, 7 to 100 months), and complete follow-up was available in 132 patients (98.5%). Ninety-five patients (71.9%) had compensatory sweating develop. Seventy patients (53%) judged their compensatory sweating to be minor and intermittent, and 25 patients (19%) judged it severe (16% embarrassing, 3% disabling). On univariate and multivariate analysis, the extent of denervation was not associated with the occurrence or the severity of compensatory sweating. The late satisfaction rate was 91.5%. Compensatory sweating and temporary relief/recurrence were equally considered to be the main causes of dissatisfaction.ConclusionCompensatory sweating was the most common long-term complication of thoracodorsal sympathectomy for primary hyperhidrosis. Its incidence and severity were not associated with the extent of sympathectomy.
