Staple Line Covering Procedure after Thoracoscopic Bullectomy for the Management of Primary Spontaneous Pneumothorax

Abstract

Thoracoscopic bullectomy together with a pleural adhesive procedure is generally accepted as the standard for the definitive treatment of primary spontaneous pneumothorax (PSP). The purpose of this study was to evaluate whether the results of a thoracoscopic bullectomy followed by coverage of the staple line with cellulose mesh and fibrin glue could be comparable with those of adhesive procedures described in the literature. Between May 2000 and February 2003, we performed 227 thoracoscopic surgeries on 219 patients with PSP using a single technique. After the bullectomy, the staple line was covered with cellulose mesh and fibrin glue. The postoperative status was evaluated with a mean follow-up of 46 months. The mean patient age was 24.3 years and 90.9 % of the 219 patients were male. Recurrent pneumothorax (37.4 %) was the most common operative indication, followed by persistent air leakage of more than 5 days (28.2 %). The mean duration of postoperative chest tube drainage was 1.6 days and the mean postoperative hospital stay was 3.8 days. Six patients experienced surgical complications (2.2 %); there was air leakage of more than 3 days in two cases, a small apical dead space in one case, a fever-associated wound problem in one case, and a reoperation due to air leakage of more than 7 days in two cases. Eleven patients (4.8 %) suffered a recurrence of pneumothorax during the follow-up period. Of these, nine cases required readmission and three (1.3 %) of these cases required a reoperation. Given the nature of a meticulous thoracoscopic bullectomy followed by coverage with cellulose mesh and fibrin glue, good surgical results can be expected without the need for a pleural adhesive procedure.
