A novel approach to control air leaks in complex lung surgery: a retrospective review

One hundred and twenty-one consecutive patients who underwent pulmonary surgery with and without Progel？ Pleural Air Leak Sealant were reviewed retrospectively. Intra-operative and 3-months postoperative data were assessed for the presence and persistence of air leaks, chest tube duration, the length of hospital stay, and complications.Seventy patients (57.9%) had IOAL. Thirty-six were treated with Progel in addition to standard intra-operative technique (pleural-sealant group; PSG) and 34 patients were treated only with standard technique (control group; CG). The percentage of post-operative air leaks in the PSG was 11% (1.2% >Grade 2 air leak) compared with 58.8% (6% >Grade 2 air leak) in the CG (p <0.0001, Leaks graded from 1？=？small air leak to 7？=？large air leak). The median chest tube duration was significantly shorter in the PSG compared with the controls (1.0 versus 2.5 days; p？<？0.0001). The median length of hospital stay was 50% lower in the PSG compared with the control group (1.5 versus 3.0？days; p？=？0.047). There were no significant differences in complications between the two groups.The results of this single-center, single surgeon, retrospective review demonstrate a significant reduction in IOAL, chest tube duration, and length of hospital stay in the in patients treated with Progel when compared with standard intra-operative closure management alone. They suggest that the use of a pleural sealant is more effective in reducing alveolar air leaks associated with lung resection compared with standard closure techniques alone and may result in both an improved surgical outcome and a reduction in costs associated with prolonged hospital stay.
