摘要


Hyperhidrosis palmaris (HP) is a rather common disease in Taiwan. Taiwan is a leading nation in terms of the surgical treatment of this disease using thoracic endoscopic sympathectomy. However, the currently available epidemiological information regarding HP is insufficient. To date, the incidence of HP and the percentage of patients treated surgically have not been reported. We investigated the incidence of HP treated in 2004 by sampling Taiwan’s National Health Insurance database. Patients who were diagnosed with HP during 2004 were identified by International Classification of Diseases, 9(superscript th) Clinical Modification code 780.8 from a database of about 22 million beneficiaries, and were followed to 2006. Those who had been diagnosed as HP in 2002 or 2003 were excluded. Patients who underwent surgery were identified by the treatment codes 83026C (dorsal sympathectomy) and 83085B (transendoscopic dorsal sympathectomy, TES). Factors included in the analysis included age, sex, time of operation and hospitalization for surgery. In total, 15,839 patients with HP were identified. The incidence was 7.2 per 10,000 beneficiaries. The study sample included 7,603 males with an incidence of 6.9 per 10, 000 beneficiaries, and 8, 236 females with an incidence of 7.4 per 10, 000 beneficiaries. The incidence was highest among patients aged 20-29 years old. The incidence decreased with increasing age (Mantel- Haenszel χ^2 test for trend, p<0.001), and 3,755 cases (23.7%) received an operation, of which 1,733 were male (22.8% of all male patients) and 2,022 were female (24.6% of all female patients) (p=0.009). Of these, 99.3% underwent transendoscopic dorsal sympathectomy, and 94.7% underwent surgery within 1 month of the initial diagnosis. Males underwent surgery sooner than females (p=0.004). Adjusted multivariate logistic regression analysis showed that patients aged 20-29 were more likely to undergo surgery than the other age groups (odds ratio: 2.28; 95% confidence interval: 2.07-2.52). Regional hospitals had the highest chance to perform the operation (odds ratio: 4.87; 95% confidence interval: 4.41-5.37). Here, we have reported the incidence of HP in Taiwan in 2004 and concluded that the incidence was higher in females than in males. About onequarter of patients underwent surgery, mostly within 1 month after attending an outpatient clinic; most surgical interventions involved endoscopic sympathectomy. This report fulfills the epidemiological information gap of HP and provides important data for future health care delivery.
