Bullous lung diseases are still disputable with respect to their definition, classification, and treatment algorithm. New approaches have been put forth especially for treatment in recent years. Prognosis is closely linked to patient selection for surgery, applied treatment methods, and surgeon's experience. Prolonged air leak is a primary problem in surgery. 1 Many techniques and equipment are used to prevent this condition. In the present study the aim was to investigate surgical treatment outcomes in bullous lung disorders complicated by pneumothorax and the effect of collagen matrix tissue supporter made of bovine pericardium and polyethylene glycol (PEG) tissue glue on prolonged air leak and complications in patients with bullous emphysema leading to secondary spontaneous pneumothorax (SSP).
METHODOLOGYThe medical records of 179 patients with SSP from January 2010 to December 2018 were retrospectively reviewed. Sixty patients with radiologically confirmed bullous emphysema, who underwent surgery, were enrolled. Nineteen patients, who were treated with tube thoracostomy, thoracentesis, or nasal oxygen alone, were excluded. The patients were randomly selected in terms of age and gender, regardless of bullous emphysema and lung parenchyma. The patients were grouped into three groups: Group 1 included 20 patients that underwent wedge resection with an endostapler supported by Peristrips made of bovine pericardium; Group 2 contained 18 patients that were applied Coseal tissue glue at the suture line after being operated with wedge resection with endostapler. Group 3 contained 22 patients that were applied Coseal tissue glue to the stapler line after being operated with wedge resection while the endostapler line was supported by Peristrips. Considering that persisting air leak from chest tube and
