Effectiveness of the polyglycolic acid patch in preventing prolonged air leakage after pulmonary decortication

This study aimed to investigate the effectiveness of an absorbable polyglycolic acid patch (PGA) in the early prevention of alveolar air leaks after pulmonary decortication operations.

Between January 2016 and December 2019, files of 185 patients with pleural effusion, empyema, or hemothorax were examined retrospectively. Thirty-five patients who underwent decortication surgery were included in the study. Two-way posteroanterior (PA) chest x-ray, computed tomography (CT), pulmonary function tests (PFT), arterial blood gas, hemogram, and biochemical tests were performed for all patients before the operation. The patients were divided into two groups. Group 1 was composed of 16 patients (45.7%) with standard decortication, and Group 2 was formed with 19 patients (54.3%) with standard decortication + PGA patch.

The median age was 55 years (minimum = 25, maximum = 75) and the vast majority (82.9%; n = 29) of patients were males. There was no significant difference between groups in age, aetiology, or sex. The most common etiological cause in both Group 1 and Group 2 was nonspecific infection (56.3% and 73.7%, respectively). When Group 2 and Group 1 were compared regarding median times (day) of air leak cessation (Group 2 = 4; Group 1 = 8.5), chest drain removal (Group 2 = 5; Group 1 = 10), and hospital discharge times (Group 2 = 8; Group 1 = 13),the durations were statistically significantly shorter in Group 2 than in Group 1 (P < 0.001).

Use of the PGA patch in pulmonary decortication operations significantly reduced the duration of air leaks, drain removal, and discharge time from the hospital in the postoperative period.
