Intermediate-term results of endoscopic transaxillary T2 sympathectomy for primary palmar hyperhidrosis. Chiou T S-M,  Chen S-C.  Br J Surg 1999;  86:  45-47. 
Endoscopic transaxillary T2 sympathectomy is currently the preferred treatment for palmar hyperhidrosis.  With this technique the T2 ganglion and its associated fibres are diathermied along the upper border of the third rib.  It is a technique that has minimal post-operative morbidity and an early almost complete success rate.  The long-term efficacy remains unclear.  This paper studied the intermediate-term results of this operative procedure.  A retrospective review was performed of 91 consecutive patients treated between 1992 and 1996.  Patients were contacted by telephone or a post questionnaire to ascertain their satisfaction, late complications and morbidity.  In the early postoperative period no patient developed a Horner's syndrome.  One patient developed a haemothorax that did not require chest drainage.  Overall, 16% developed recurrent sweating but none required further surgery.  78% were satisfied with the outcome of their operation.  However, 13% were dissatisfied mainly due to compensatory hyperhidrosis which occurred in 97% of all patients within the first year.  It was concluded that the results of endoscopic sympathectomy deteriorated progressively from the immediate outcome and the compensatory hyperhidrosis was the principal reason for dissatisfaction
