From: Successful treatment of bilateral empyema with bilateral fistulae using free intercostal muscle flap
a CT after the first operation revealed a bronchopleural fistula in the right pleural cavity. The right B10c was thought to be the responsible bronchus (yellow arrow). b Endobronchial Watanabe spigots were inserted into the right B10b and B10c bronchi. c The right S10 fistula was superimposed and closed using a pedicled intercostal muscle flap (white arrow). d CT after the second operation showed that both sides of the lung expanded without residual pleural space
