[Re-operation for Recurrent Spontaneous Pneumothorax].

INTRODUCTION The decrease in the postoperative recurrence rate after thoracoscopic bullectomy for spontaneous pneumothorax is an issue that should be tackled even at this moment. We presently make sure to do the reinforcement of the visceral pleura around between the staple line on bullectomy and the common sites of the new-born bullae such as apex, top site of S6, interlobar fissure to prevent postoperative recurrence. PURPOSE We evaluated the latest efficacy of preventing postoperative recurrence by widely covering the staple line and the common sites of the new-born bullae with a polyglycolic acid( PGA) sheet after bullectomy. METHODS Retrospective analyses were performed for 1,097 patients with spontaneous pneumothorax who received thoracoscopic bullectomy at our hospital between January 2011 and December 2020. The 1-year, 3-years, 5-years postoperative recurrence rates of 229 patients with spontaneous pneumothorax were respectively calculated with the Kaplan-Meier method. RESULTS The 1-year, 3-years, 5-years postoperative recurrence rates of spontaneous pneumothorax were 0.9%, 3.6%, 4.0%, respectively. CONCLUSIONS Combination treatment with bullectomy and wide coverage of the staple line and the common sites of the new-born bullae with the PGA sheet reduced satisfyingly postoperative recurrence rates of spontaneous pneumothorax.
