Summary
A new laser-assisted thoracoscopic surgery effectively treats palmar hyperhidrosis (PH), offering a safe and minimally invasive option for excessive sweating. This advanced technique provides lasting relief with reduced recovery time compared to traditional methods.
Area of Science:
- Thoracic surgery
- Minimally invasive procedures
- Laser surgery
Background:
- Palmar hyperhidrosis (PH) is a common condition, particularly in certain populations.
- Existing treatments for PH often yield unsatisfactory results.
- A need exists for more effective and minimally invasive therapeutic options.
Purpose of the Study:
- To introduce and evaluate a novel therapeutic technique for palmar hyperhidrosis.
- To assess the safety and efficacy of laser-assisted thoracoscopic sympathectomy.
- To compare this new method with conventional open sympathectomy procedures.
Main Methods:
- Development of a combined video-thoracoscopic and surgical laser system (CO2 and Nd:YAG lasers).
- Procedure performed under general anesthesia with one-lung ventilation.
- Identification and ablation of the sympathetic trunk (T2 segment) using laser extirpation with intraoperative monitoring.
Main Results:
- Successfully treated 300 patients with palmar hyperhidrosis (ages 6-63).
- Achieved satisfactory relief in most patients (287/300), with minimal complications (no vital sign changes, lung injury, bleeding, or Horner's syndrome).
- Common complication was compensatory hyperhidrosis (approx. 50%); low recurrence rate (3/200) after >12 months follow-up.
Conclusions:
- Laser-assisted thoracoscopic sympathectomy is a safe, minor procedure for palmar hyperhidrosis.
- The technique offers definite, long-lasting therapeutic effects with minimal discomfort and scarring.
- Operation time and hospital stay are significantly reduced compared to open sympathectomy.
