Compensatory hyperhidrosis after different surgeries at the same sympathetic levels: a meta-analysis.

BACKGROUND

Different techniques of video-assisted thoracoscopic sympathetic surgery have become the radical treatments for palmar and axillary hyperhidrosis (AH). However, there is no consensus over which technique can make a minimal incidence of compensatory hyperhidrosis (CH). This study was designed to compare the incidence of CH after different techniques at the same sympathetic levels in the treatment of upper limb and facial hyperhidrosis (FH).

METHODS

The databases of PubMed, Web of Science, ScienceDirect, Ovid Medline, Embase, and Cochrane Library were searched to identify studies comparing different surgical techniques at the same sympathetic levels for upper limb and FH. The data was analyzed by Revman 5.3 software.

RESULTS

A total of ten studies involving 896 patients were included, of whom 149 underwent sympathectomy, 435 underwent sympathicotomy, and 312 under endoscopic sympathetic clip (ESC). Meta-analysis showed that the difference of incidence of CH and patients' satisfaction was not significant between sympathectomy and sympathicotomy (P=0.05, 0.19, respectively). But, the incidence of CH is significant lower after ESC than after sympathicotomy (OR: 1.58, 95% CI: 1.04-2.38, P=0.03). However, the incidence of moderate/severe CH between these two groups is not significant different (OR: 1.49, 95% CI: 0.93-2.39, P=0.10).

CONCLUSIONS

If only CH and the same sympathetic levels concerned, sympathectomy and sympathicotomy is equal for upper limb hyperhidrosis and FH. And, ESC should be recommended for a lower incidence of CH, comparing with sympathicotomy.
