Conditions

Palmar Hyperhidrosis

Brief summary

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.

Design outcomes

Primary

Measure	Time frame	Description
Anatomical variation of the sympathetic ganglions	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

Measure	Time frame	Description
Improvement of palmar sweating	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.
Degree of compensatory hyperhidrosis	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.
