Abstract:Objective To compare the efficacy of two different approaches (xiphoid incision and bilateral chest wall incision) of uniport thoracoscopic bilateral T3 sympathectomy in treatment of primary palmar hyperhidrosis. Methods From October 2011 to September 2015, 47 patients underwent uniport thoracoscopic bilateral T3 sympathectomy for primary palmar hyperhidrosis. 11 cases of them underwent xiphoid incision (group A), 36 cases underwent bilateral axillary incision (group B), then observe the postoperative pain, postoperative complications and the degree of symptoms improvement, recurrence and compensatory hyperhidrosis, compare the efficacy and safety between the two groups. Results Patients in the two groups were successfully completed surgery, average operation time of group A was (74.00 ± 12.00) min, average hospitalization time was (2.00 ± 0.70) d, average does of analgesic drugs in postoperative 1 week (Paracetamol and dihydrocodeine) was (26.30 ± 9.20) mg; average operation time in group B was (56.00 ± 16.00) min, average hospitalization time was (2.30 ± 1.00) d, average does of analgesic drugs in postoperative 1 week (Paracetamol and dihydrocodeine) was (26.30 ± 9.20) mg. No recent complications such as hemothorax, pneumothorax, Hornor syndrome was observed. No recurrence during the follow-up period was observed. While the average operation time of xiphoid incision group is longer than bilateral axillary incision group, there was no significant difference in the various complications and treatment effect, but xiphoid incision group significantly relieve postoperative pain. Conclusion Compared with the traditional uniport bilateral axillary incision thoracoscope T3 sympathectomy, the xiphoid incision uniport thoracoscope T3 sympathectomy treat primary palmar hyperhidrosis has more minimally invasive advantages and reduced postoperative pain which is valid and safety, and worthy of further promotion.
