[Current appraisal of endoscopic thoracic sympathectomy: results of the national questionnaire surgery].
A questionnaire survey was performed in order to investigate the current status of endoscopic thoracic sympathectomy in Japan. Four hundred and twenty-nine (429) university, national or public hospitals with a minimum of 400 beds were included. A total of 248 of these hospitals responded. Among them 63 (25%) performed this procedure. The total of the cases was 1116. The number of access port and the technique for defunctioning the sympathetic chain were broadly divided into three methods. These methods were equally carried out among the departments. The clinical results were judged as satisfactory in the great majority of patients and the frequency of complications was low. On the other hand, the overall incidence of compensatory sweating remained relatively high and accumulated as the number of cases increased. But the reported frequency differed strikingly from hospital probably for lack of an objective way of quantifying following sympathectomy. Although overall complications were infrequent, the need for conventional thoracotomy to stop bleeding occurred in some cases. Therefore even this simple endoscopic operation demands the utmost surgical care, skill and experience. A few recurrences of preoperative symptoms were seen in the follow-up suggesting that all patients must be continually monitored after the operation.
