Abstract BACKGROUND: There are rare reports of video-assisted thoracoscopic resympathicotomy for patients with palmar hyperhidrosis. I present our experience in treating a persistent or recurrent palmar hyperhidrosis after primary endoscopic sympathectomy or sympathicotomy and discuss the perioperative management. METHODS: We reoperated on 42 patients using a technique of video-assisted thoracoscopic resympathicotomy. All patients were placed in a semi-sitting position under single- or double-lumen intubated anesthesia. An 8-mm, 0 degrees thoracoscope was used to interrupt the nerve conduction to the palms from the T2 and T3 ganglia, through one or two 0.8-cm subaxillary incisions. RESULTS: The reasons for failure of endoscopic sympathectomy or sympathicotomy in 26 patients included pleural adhesion (15 of 26, 57.7\%), incorrect identification of T2 ganglion (3 of 26, 11.5\%), vessel overriding or close to sympathetic nerve (3 of 26, 11.5\%), incomplete interruption of sympathetic nerve (2 of 26, 7.7\%), medially located sympathetic nerve (2 of 26, 7.7\%), and aberrant venous arch (1 of 26, 3.8\%). The causes of recurrent palmar hyperhidrosis after primary transthoracic endoscopic sympathicotomy or sympathectomy (TES) in 16 patients included a possible effect of T3 ganglion (8 of 16, 50\%), Kuntz fiber (3 of 16, 18.8\%), nerve regeneration (3 of 16, 18.8\%), and incomplete interruption of T2 ganglion (2 of 16, 12.5\%). Surgical complications included pneumothorax (1 patient, 2.4\%), hemothorax (1 patient, 2.4\%), and compensatory sweating (36 patients, 86\%). All patients had obtained successful bilateral sympathectomies and had satisfactory results after a mean of 32.1 months of follow-up. CONCLUSIONS: Video-assisted thoracoscopic resympathicotomy is an effective and safe method for a previously unsuccessful sympathectomy or recurrent palmar hyperhidrosis if the surgeon acknowledges possible anatomic variations and can overcome the problems related to pleural adhesions.
