Nil Intervention is at Times the Best Intervention: Benign emptying of pneumonectomy space.

Abstract

A sudden drop of air-fluid level in the pneumonectomy space in the absence of a bronchopleural fistula and pleural infection is termed benign emptying of the pneumonectomy space (BEPS). We report a 28-year-old female patient who presented to a tertiary care referral centre, in Pondicherry, India in 2020 with multiple episodes of vomiting. Subsequent to a left-sided pneumonectomy due to tuberculosis, she was diagnosed with BEPS. Generally, patients with BEPS are clinically stable, afebrile with no fluid expectoration and have a normal white blood cell count. Bronchoscopy reveals an intact bronchial stump and pleural fluid cultures are often sterile. In terms of management, close monitoring and early detection of a bronchopleural fistula are the key points. BEPS should be a differential diagnosis in case of a drop in the air-fluid level of the post-pneumonectomy space. Awareness of this entity is crucial as it helps prevent unnecessary and morbid surgical interventions.
