Effectiveness of Polyglycolic Acid Sheet Covering and Platelet-Rich Plasma after Video-Assisted Thoracic Surgery for Spontaneous Pneumothorax

Abstract Background Video-assisted thoracic surgery (VATS) is widely used for the treatment of spontaneous pneumothorax, and the recurrence rate is high. The goal of the study was to examine the use of polyglycolic acid (PGA) sheets, together with platelet-rich plasma (PRP) from autologous blood for the prevention of postoperative recurrence of spontaneous pneumothorax. Materials and Methods We performed a retrospective study of 65 patients who underwent VATS for spontaneous pneumothorax from March 2008 to November 2011. The patients were divided into groups: without reinforcement (Group A, n = 33) and with reinforcement of the visceral pleura around the staple lines with the PGA sheet and PRP (Group B, n = 32). The postoperative follow-up period was 18 months. Results Chest tubes were used for 3.4 and 3.1 days in Groups A and B, respectively, with no significant difference between the groups. However, the recurrence rate (18.2%; 6 cases) in Group A was significantly higher than that in Group B (p = 0.02). The recurrence rates in patients younger than 25 years in Group A and Group B were 26.1 and 0.0%, respectively (p = 0.03). In Group A, the mean age with recurrence (18.3 years old) was significantly lower than the mean age without recurrence (p = 0.03). Conclusion These results suggest that the use of PGA sheets and PRP might be effective for the prevention of postoperative recurrence of spontaneous pneumothorax.
