Zusammenfassung: | Objective
Various surgical procedures have been performed to decrease the recurrence of primary spontaneous pneumothorax after video-assisted thoracic surgery. This study aimed to examine the efficiency of pleural coverage for the prevention of postoperative recurrence in relatively young patients.
Methods
Between January 2008 and December 2012, a total of 357 cases of 345 patients (age 15–29 years) with primary spontaneous pneumothorax who underwent bullectomy at 13 institutions were enrolled in this multi-institutional retrospective cohort study. A concurrent bilateral operation was counted as two cases. Polyglycolic acid sheets were used in 238 cases, and oxidized regenerated cellulose sheets were used in 37 cases to cover the visceral pleura, with no pleural coverage in 82 cases. The average observation period was 4.2 ± 2.0 years.
Results
Postoperative recurrence was observed in 50 cases (14.0%) after video-assisted thoracic surgery. Twenty-six cases (10.9%) in the polyglycolic acid group, eight (21.6%) in the oxidized regenerated cellulose group, and sixteen (19.5%) in the non-coverage group experienced postoperative recurrence. Kaplan–Meier analysis revealed that the rate of freedom from postoperative recurrence in the polyglycolic acid group was significantly higher than that in the non-coverage group. Multivariate analysis showed that age ≥ 20 years and coverage with polyglycolic acid sheets were associated with reduced risk factors for postoperative recurrence.
Conclusion
Pleural coverage with a polyglycolic acid sheet is suggested to be effective in preventing postoperative recurrence of pneumothorax compared with non-coverage in relatively young patients. |
