Staple-Line Reinforcement for Prevention of Pulmonary Air Leakage

13:46 EDT 18th September 2014 | BioPortfolio


The aim of this study is to compare the efficacy of FORESEAL with stapling alone or associated with tissue sealant or glue in terms of air leakage duration after lung resection for cancer.

Hypothesis: to show a significant difference of 1 day in the average duration of air leakage between the 2 groups with a standard deviation of 3 (α =0.05 and β=0.10).


Air leaks continue to be the most common complication after pulmonary resection even using a stapling device. Double chest tubes after lobectomy is a well established method for drainage of the pleural cavity to allow adequate expansion of the remaining lung.

FORESEAL has been developed to reduce air leaks by buttressing the staple line. It is a absorbable vegetal biopolymer in the form of sleeves, CE marked and indicated for prevention of air leakage after pulmonary resection with stapling device. It acts as a suture reinforcement as well as a sealant thanks to its jellification.

Sealants are also commonly used in addition to stapling to prevent air leakage. The aim of this study is to compare the efficacy of FORESEAL with stapling alone or associated with sealants.

This is a multi centre, prospective controlled and randomised clinical study.

Medical and Biotech [MESH] Definitions

Tumors or cancer of the LUNG.

A technique of closing incisions and wounds, or of joining and connecting tissues, in which staples are used as sutures.

A collective term for precoordinated organ/neoplasm headings locating neoplasms by organ, as BRAIN NEOPLASMS; DUODENAL NEOPLASMS; LIVER NEOPLASMS; etc.

Absence of air in the entire or part of a lung, such as an incompletely inflated neonate lung or a collapsed adult lung. Pulmonary atelectasis can be caused by airway obstruction, lung compression, fibrotic contraction, or other factors.

A diverse group of lung diseases that affect the lung parenchyma. They are characterized by an initial inflammation of PULMONARY ALVEOLI that extends to the interstitium and beyond leading to diffuse PULMONARY FIBROSIS. Interstitial lung diseases are classified by their etiology (known or unknown causes), and radiological-pathological features.
