This study introduces a novel endoscopic laser technique for treating palmar hyperhidrosis, offering a precise and safe surgical option. The procedure resulted in minimal complications and improved patient outcomes for excessive palm sweating.

Area of Science:

  • Thoracic Surgery
  • Minimally Invasive Procedures
  • Laser Surgery

Background:

  • Palmar hyperhidrosis is a prevalent condition, particularly in Oriental populations.
  • Existing treatments for palmar hyperhidrosis often lack complete efficacy.
  • Video-endoscopic surgery offers potential for improved treatment of hyperhidrosis.

Purpose of the Study:

  • To introduce and evaluate a new therapeutic technique for palmar hyperhidrosis using video-endoscopic surgery combined with Nd-YAG laser.
  • To assess the safety, efficacy, and outcomes of this minimally invasive approach.

Main Methods:

  • A novel technique combining video-endoscopic surgery, Nd-YAG laser, electrocautery, and laser Doppler flowmeter was developed.
  • General anesthesia with one-lung ventilation was employed for endoscopic thoracic sympathectomy.

  • Sympathetic trunk identification was confirmed via electric stimulation and vasomotor response before laser vaporization.

    • Main Results:

    • Twenty patients underwent bilateral sympathectomy, primarily targeting the T2 sympathetic trunk.
    • The procedure demonstrated no lung injury or bleeding, and importantly, no cases of Horner's syndrome were observed.
    • Precise ganglionectomy was achieved under magnified endoscopic vision, leading to a definite and long-lasting therapeutic effect.

    Conclusions:

    • The described endoscopic Nd-YAG laser sympathectomy is a safe, effective, and minimally invasive treatment for palmar hyperhidrosis.
    • This technique offers significant advantages, including reduced operation time, shorter hospital stays, and minimal scarring compared to open procedures.
    • The precise targeting and clear visualization contribute to a high likelihood of successful and durable treatment outcomes.
