T3/T4 thoracic sympathictomy and compensatory sweating in treatment of palmar hyperhidrosis / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Compensatory sweating (CS) is one of the most common postoperative complications after thoracic sympathectomy, sympathicotomy or endoscopic sympathetic block (ESB) for palmar hyperhidrosis. This study was conducted to examine the relevance between CS and the sympathetic segment being transected in the surgical treatment of palmar hyperhidrosis, and thus to detect the potential mechanism of the occurrence of CS.</p><p><b>METHODS</b>Between October 2004 and June 2006, 163 patients with primary hyperhidrosis were randomly divided into two groups, T(3) sympathicotomy (78 patients) and T(4) sympathicotomy (85), who were operated upon under general anesthesia via single lumen intubation and intercostal video-mediastinoscopy (VM).</p><p><b>RESULTS</b>No morbidity or mortality occurred. Palmar hyperhidrosis was cured in all patients. Follow-up (mean (13.8 +/- 6.2) months) showed no recurrence of palmar hyperhidrosis. The difference of rates of mild CS in groups T(3) and T(4) was of no statistical significance. The rate of moderate CS was significantly lower in group T(4) than in group T(3). No severe CS occurred.</p><p><b>CONCLUSION</b>The rates of occurrence and severity of CS are lowered with the lower sympathetic chain being transected.</p>

Intercostal video-mediastinoscopy: a report of 701 cases / 中华外科杂志

<p><b>OBJECTIVE</b>To summarize the experience of intercostal video-mediastinoscopy (VMS) in treatment for mediastinal masses, malignant pleural effusion and palmar hyperhidrosis.</p><p><b>METHODS</b>The clinical data of 701 patients received intercostal VMS from November 2001 to June 2007 were summarized retrospectively. Forty-eight patients with mediastinal masses and 46 patients with suspected malignant pleural effusion underwent intercostal VMS pleural biopsy (39 cases with talc pleurodesis) and 607 patients with palmar hyperhidrosis underwent bilateral intercostals VMS thoracic sympathectomy.</p><p><b>RESULTS</b>No mortality and morbidity were reported in this group. Definitive pathologic diagnosis had been made through VMS mediastinal masses biopsy in mediastinal masses and pleural biopsy in pleura effusion. The efficiency of talc pleurodesis was 100% for 39 cases. The symptoms of sweating of hands in 607 patients with palmar hyperhidrosis disappeared completely, all patients' hands became dry with a 1.5 degrees C to 3.0 degrees C increase of the skin temperature immediately after operation. No recurrence occurred during the follow-up.</p><p><b>CONCLUSION</b>VMS is a simple, convenient and alternative procedure for the treatment of mediastinal masses, malignant pleural effusion and palmar hyperhidrosis.</p>
