This study aims to evaluate the long-term outcomes of compensatory hyperhidrosis (CH) after thoracoscopic sympathectomy and explore the risk factors affecting postoperative CH in primary palmar hyperhidrosis(PPH) patients. A retrospective analysis was conducted on patients who underwent thoracoscopic sympathectomy in the thoracic surgery department of our hospital from January 2015 to May 2022. Long-term follow-up surveys was conducted to collect data on post-operative satisfaction, PPH recurrence, and CH occurrence. Postoperative CH outcomes were assessed using the HDSS and satisfaction scores scale. Univariate and multivariate logistic regression analyses were used to identify independent risk factors for postoperative CH. A total of 152 patients was included in the final study, with 113 cases in the CH group and 39 cases in the nCH group. The incidence of postoperative CH was 74.3% (113/152), within which 33.6% (38/113) were severe CH. The median follow-up time was 3.1 years(2.5-5.5y) and the median interval of CH onset after surgery was 30 days (14-90d). Univariate analysis showed that body mass index(BMI), surgical time, and transected nerve level are correlated with CH, with statistically significant differences. Multivariate logistic regression analysis indicated a higher BMI (OR = 0.864, 95% CI 0.755-0.989, P < 0.05) is the independent risk factor for the occurrence of CH. There was no statistically significant difference in HDSS scores among CH patients at 1 month, 1 year, and 3 years after surgery. A higher BMI is the independent risk factor for postoperative CH after thoracoscopic sympathectomy. The incidence and severity of postoperative CH kept stable during a long term follow up.
