Position of a chest tube at video-assisted thoracoscopic surgery for spontaneous pneumothorax.
BACKGROUND
Video-assisted thoracoscopic surgery (VATS) is a good therapeutic option for young patients with primary spontaneous pneumothorax (PSP), but there sometimes exists unexpected prolonged hospital stay due to air leak after the operation.


OBJECTIVE
The goal of this retrospective study was to clarify if the position of the chest tube placed at VATS for PSP affected the periods of postoperative hospital stay.


METHODS
Seventy-one cases with PSP under age 40 who undertook VATS from January 1994 to February 2001 were examined for several factors. They were classified into two groups by the location of the tip of the chest tube placed at VATS as follows: upper medial pleural space (group I) and outside of there (group II).


RESULTS
Fifty-three of the 71 cases (75%) were classified in group I and 18 (25%) were in group II. Between the two groups, there were no differences as to preoperative characteristics of the patients and intraoperative findings of blebs or bullae. On the other hand, postoperative air leak-related complications were more frequent in group II than in group I (p=0.004). Mean postoperative hospital stay was 5.1+/-1.9 days in group I and 8.4+/-4.3 days in group II (p<0.0001).


CONCLUSIONS
Patients with the tip of the chest tube in the upper medial pleural space at VATS could be discharged earlier than the other patients. The chest tube placement is one of the important factors for the outcome of VATS for PSP.
