Background:
Endoscopic thoracoscopic sympathectomy (ETS) is the gold standard therapy for primary focal palmar hyperhidrosis (PFPH), resulting in high patient satisfaction rates. The most common side effect of ETS is compensatory hyperhidrosis (CH). Previous studies followed patients' satisfaction degree of surgery and the incidence of CH during a limited follow-up period of 1 to 3 years. The purpose of this study was to investigate the long-term outcomes and patient satisfaction after ETS.
Materials And Methods:
After approval of our institutional review board, we conducted a retrospective review of all consecutive patients who underwent ETS for PFPH at our institution between 1998 and 2019. Electronic medical records were reviewed for short-term outcomes. Long-term outcomes were collected through telephone questionnaires. Primary outcome was the resolution of PFPH. Secondary outcomes were CH and long-term patient satisfaction.
Results:
During the study period, 256 patients underwent ETS to treat primary focal palmar hyperhidrosis at our institution between the years 1998-2019. One-hundred and fifty (58.6%) patients agreed to participate in the study and were included in the final analysis. The mean age was 23.8 (17 to 58) years, 56% were females. The mean follow-up time was 11±6.1 (1 to 22) years. Ninety-four percent reported resolution of PFPH; however, CH was reported by 90% of participants. CH decreased mean patient satisfaction score from 4.8±0.5 to 3.8±2 ( P =0.009). This effect was more pronounced in patients with CH of the head and neck ( P =0.009). Patients' satisfaction decreased over time from a mean of 4.8±0.4 in the first year after surgery to a mean of 3.7±1.4 12 years or more after surgery ( P <0.001). Despite this, 79% of patients reported they would recommend ETS to other patients.
Conclusions:
ETS for PFPH is highly effective and results in high patient satisfaction rates even after long-term follow-up. Despite high rates of postoperative CH, nearly 80% of patients would still recommend the procedure to fellow patients, justifying its reputation as the gold standard treatment for PFPH.
