Eloesser flap is a single-stage procedure for the treatment of severe pleural empyema, and involves a U-shaped incision and the resection of a number of subjacent posterolateral ribs. The U-shaped flap is then folded into the pleural space creating a permanent communication.
Unlike the Clagett procedure, from which it is radiographically difficult to distinguish, the Eloesser flap is not reversible.
