Although techniques for closing the bronchial stump after pneumonectomy or lobectomy are numerous, none seem to offer a complete protection against bronchial fistulization.

In this institution the usual procedure includes the standard use of interrupted fine silk sutures reinforced by a pedicled pleural flap. This technique is usually satisfactory. If pleura is not readily available, pericardial fat is used as suggested by Brewer.1

A recent fatal failure with the latter technique in a case of pulmonary abscess has prompted the investigation reported in this article.

Material and Methods  Mongrel dogs were used in this experiment. In 11 animals, after induction of anesthesia with intravenous thiopental sodium and endotracheal intubation, a standard thoracotomy was carried out either in the right or left fifth intercostal space. The pulmonary pedicle was dissected free and the hilar structures individually ligated and transfixed, the artery first, then both pulmonary veins. The main stem bronchus
