RESEARCH ARTICLE Open Access What factors predict recurrence of a spontaneous pneumothorax? Hidetaka Uramoto * , Hidehiko Shimokawa and Fumihiro Tanaka Abstract Background: The purpose of this retrospective study was to identify the risk factors for postoperative recurrence for the patients with a spontaneous pneumothorax (SP). A total of 214 patients were studied over a period of five years. Of these patients, 189 (88.3%) and 25 (11.7%) underwent video assisted thoracoscopic surgery (VATS) and an open approach for treatment, respectively. There were 35 (16.4%) postoperative recurrences. Methods: The data on patient characteristics, surgical details, and perioperative outcomes were analyzed. We compared the clinicopathological characteristics between recurrent and non-recurrent cases, and used logistic regression models to predict the risk factors for postoperative recurrence. Results: The differences in the age, gender, lesion site, location, ipsilateral SP (ISP), and contralateral SP (CSP) did not reach statistical significance between the two groups. However, the incidence of recurrence was higher in the subjects without any smoking history, and who had comorbidities, and a history of surgery for ISP. Concerning intraoperative factors, there were no significant differences with regard to the approach, buttress stapling, covering, surgeon, or length of the operation. The postoperative recurrence rate was higher in the patients who had been hand-stitched compared to those who had undergone instrument-based repair for blebs. There were no significant differences in the perioperative outcomes. The logistic regression models indicated that non smokers, those with comorbidities, and those who had previously undergone surgery for ISP had a higher rate of postoperative recurrence. Conclusions: We conclude that a history of no smoking, the existence of comorbidities, previous surgery for ISP, and hand stitching increase the risk of postoperative recurrence. Therefore, surgeons must be aware of these risk factors, and more carefully monitor such patients for recurrence. Keywords: Spontaneous pneumothorax, Operation, VATS, Postoperative recurrence, Risk factor Background Spontaneous pneumothorax (SP) remains a significant health problem because of the high recurrence rate during thoracic drainage and conservative treatments [1]. Even when surgical management is performed, the recurrence rate was estimated to be approximately 10%20% [2]. Therefore, reinforcement of the visceral pleura around the staple line has been used in clinical practice [2]. Nevertheless, the best procedure has not yet been established, and the results are by no means satisfactory at present. The purpose of this study was to determine the risk factors for recurrent pneumo- thorax after surgery. Methods Patients and clinicopathological features The institutional review board approved this study. From 2005 to 2010, 221 patients requiring surgery due to SP were included in this retrospective study conducted at the University of Occupational and Environmental Health. Preoperative investigations included chest radiographs and a high-resolution computed tomographic (CT) scan of the thorax. Six patients with ipsilateral lung cancer and 1 with lymphangioleiomyomatosis (LAM) were excluded from the analyses. Finally, a total of 214 patients were included in the present series.
