[Ineffective and recurrent cases of thoracoscopic sympathectomy for hyperhidrosis and intractable pain]

Abstract

We reported the cases of thoracoscopic sympathectomy, that is, six cases of hyperhidrosis, three of post herpetic neuralgia, and four of reflex sympathetic dystrophy, including recurrent or incompletely resected or ineffective ones. Recently this procedure for hyperhidrosis had been performed frequently because of its effectiveness, less pain, early discharge and cosmetic aspect. For an ineffective case of hyperhidrosis abdominal respiration which emphasized the exhalation and using an upper abdomen decreased the sweating. The balance of autonomic nerve system, toward parasympathetic dominant, was thought to be improved by conscious respiration. The decrease of sweating right after the operation in a case of incomplete resection indicated that intraoperative maneuver could restrict the sympathetic nerve. This procedure for a pain control could be less effective than that for hyperhidrosis, so an adequate preoperative informed consent was thought to be necessary.
