Fluorescent Thoracoscopy Used in Surgery for Palmar Hyperhidrosis

T3/T4 endoscopic thoracic sympathicotomy is a widely accepted and effective treatment for primary palmar hyperhidrosis. However, sympathetic ganglions are invisible with traditional thoracoscopy and until now, the location of ganglions are confirmed by rib indirectly. The team from thoracic department of Peking University People's Hospital discovered that the sympathetic ganglions can be visualized with fluorescent thoracoscopy. Thus, investigators want to apply fluorescent thoracoscopy in sympathicotomy of palmar hyperhidrosis, to conduct a more precise operation and compare the efficiency of the novel and traditional methods.

Treatment and study plan

Near-Infrared Imaging Thoracoscopy

Procedure

Sympathicotomy performed by near-infrared imaging thoracoscopy

Primary outcomes

  1. Anatomical variation of the sympathetic ganglions

    Time frame: during surgery

    Record the spatial relationship between sympathetic ganglions and ribs, for example: T3/R4 represents the T3 sympathetic ganglion is located on the 4th rib.

Secondary outcomes

  1. Improvement of palmar sweating

    Time frame: 1 month after surgery

    Use questionnaire including 3 descriptive names of scale ( over dry, comfortable and wet) to record the surgical effect on palmar sweating.

  2. Degree of compensatory hyperhidrosis

    Time frame: 1 month after surgery

    Use questionnaire including 4 descriptive names of scale ( none, mild, moderate and severe) to record the side effect (compensatory hyperhidrosis) of this surgery.
