Pneumonectomy and Omental Transposition for COVID-19–Related Empyema and Bronchopleural Fistula Risk: A Case Report
This case report describes a successful staged surgical approach involving completion pneumonectomy followed by omental transposition to manage a severe, treatment-refractory COVID-19-related empyema and mitigate the high risk of bronchopleural fistula in a patient with compromised muscle flap options.

Imagine the human body as a bustling, high-tech city where the lungs are the massive air filtration plants keeping everything fresh. Sometimes, a viral invader like the coronavirus (COVID-19) crashes the gates, not just causing a mild cough, but turning the filtration plant into a toxic, pus-filled swamp. In the medical world, this is called an "empyema," a severe infection where the space around the lung fills with gunk. When the infection gets so bad that the lung tissue dies and can't be saved, surgeons have to perform a "pneumonectomy," which is the drastic but necessary act of removing the entire lung.
However, removing a lung is like taking out a giant, heavy pipe from a wall; the hole where the pipe used to connect (the "bronchial stump") is a major weak spot. If that hole doesn't seal perfectly, air and infection can leak out, creating a dangerous tunnel called a "bronchopleural fistula" (BPF). Doctors usually try to patch this hole with a "muscle flap"—a piece of healthy muscle from the patient's own body, kind of like using a spare tire to seal a leak. But what happens if the patient's muscles are too weak, or if the infection has already damaged the usual muscle sources? That's the tricky puzzle this paper tackles: finding a new, super-strong patch for a lung that has been ravaged by a severe infection.
This case report tells the dramatic story of a 64-year-old man whose lungs were devastated by a COVID-19 infection that turned into a massive, trapped abscess. After his first surgery to clean things up failed to save his lung, he returned three months later with a lung that was essentially dead and encased in a thick, hard shell of infection. The surgeons had to perform a "completion pneumonectomy," removing the entire left lung. But they faced a major problem: the usual "spare tire" muscles (like the latissimus dorsi) had already been cut during his first surgery, and his diabetes made the remaining muscles risky to use because they might not get enough blood to heal.
To solve this, the medical team came up with a clever two-step plan. First, they removed the lung and cleaned the area thoroughly. Then, they waited 14 days to let the patient's body stabilize and get stronger. In the second step, they performed a procedure called "omental transposition." Think of the omentum as a fatty, apron-like blanket inside the belly that is packed with its own tiny blood vessels and immune cells. The surgeons carefully moved this "belly apron" up into the chest cavity to wrap around and reinforce the open end of the airway where the lung used to be. This wasn't just a patch; it was a living, breathing shield that brought fresh blood and infection-fighting power right to the most vulnerable spot.
The result was a success story. The patient recovered without developing the dangerous air leak (BPF) that often plagues these difficult surgeries, and he kept his remaining lung working well. The authors suggest that while removing a lung for infection is rare and risky, using this "belly apron" technique is a viable and powerful option when the standard muscle patches aren't available or safe. It highlights a new way to handle the worst-case scenarios of severe infections, showing that sometimes the best repair kit is hidden right inside the patient's own belly.
