Uniportal endoscopic thoracic sympathectomy for treatment of palmar and axillary hyperhidrosis: analysis of 2000 cases.
OBJECTIVE
Primary hyperhidrosis of the upper limbs is a common and troublesome condition in Taiwan. Therefore, we present our experience in treating hyperhidrosis via uniportal endoscopic thoracic sympathectomy.


METHODS
Between April 1993 and March 2000, a total of 2000 patients underwent endoscopic thoracic sympathectomy for treatment of palmar or axillary hyperhidrosis. There were 1520 patients with palmar hyperhidrosis and 480 patients with axillary hyperhidrosis. There were 788 male and 1212 female patients, with a mean age of 22.9 years (range, 9-60 yr). All patients were placed in a semi-sitting position, with single-lumen-intubation anesthesia. We performed T2 sympathectomy at the second and third rib beds for patients with palmar hyperhidrosis, using an 8-mm, 0-degree, offset thoracoscope (Karl Storz GmbH & Co., Tuttlingen, Germany), via a 0.8-cm incision below each axilla. Similar procedures were used for T3 and T4 sympathectomies at the third, fourth, and fifth rib beds for patients with axillary hyperhidrosis. Questionnaires were sent to all patients after surgery.


RESULTS
Among these 2000 patients, successful bilateral sympathectomies were performed for 1992 patients. The operations were usually completed within 20 minutes (range, 10-30 min). Most patients were discharged within 4 hours after surgery. The surgical complications were minimal, including pneumothorax (10 cases, 0.5%), segmental atelectasis (7 cases, 0.35%), hemothorax (2 cases, 0.1%), and mild wound infections (2 cases, 0.1%). There were no surgery-related deaths. The mean postoperative follow-up period was 51.7 months (range, 6-89 mo). A total of 1720 patients (86%) developed compensatory sweating of the trunk and lower limbs. The recurrence rates for palmar and axillary hyperhidrosis after surgery were 0 and 4.1% in the first year, 0.1 and 8.2% in the second year, 0.5 and 10.4% in the third year, 0.6 and 14.1% in the fourth year, and 1.3 and 16.7% in the fifth year, respectively.


CONCLUSIONS
Uniportal endoscopic thoracic sympathectomy is a safe, effective method for the treatment of patients with palmar or axillary hyperhidrosis. For surgery, both a semi-sitting position and single-lumen-intubation anesthesia are recommended.
