[Do pericardial strips (Peri-Strip) facilitate the follow-up after pulmonary surgery in emphysematous patients?].

The aim of this study was to evaluate the contribution of bovine pericardial strips (Peri-Strip) to achieve aerostasis within emphysematous lungs. A preliminary evaluation included 15 patients (13 men and 2 women, mean age 57 years) with severe emphysema (mean FEV-1: 28.6 +/- 10.2% of predicted, mean RV: 18.4 +/- 41.3% of predicted). Two patients were on ventilator owing to acute respiratory failure. Indication for surgery was elective surgery for emphysema in 9 patients, emergency surgery for emphysema in 2, and resection for bronchogenic cancer in 4 patients. The various procedures included single aerostasis in 1, unilateral bullectomy in 6, bilateral volume reduction in 4, thoracoscopic wedge resection for peripheral cancer in 1 and lobectomy for cancer in 3 (2 of which underwent simultaneous bullectomy) Peri-Strip were used to buttress the staple lines at the base of bullae, on parenchymatous transsection lines, and on the borders of fissures. One patient who underwent emergency thoracotomy for single aerostasis died 8 days post-operatively due to multiple organ failure. Another patient developed pneumonia which resolved under treatment. Mean duration of air leaks was 5.6 days (0-21, median 8). Two patients required tube thoracotomy for residual effusions. Mean hospital stay was 17 days (6-53; median 16). We conclude that use of Peri-Strip offered a real benefit to 12 patients; no evidence of benefit was noted in 3 patients.
