Successful non-operative management of acute incarcerated lung herniation after video- assisted thoracoscopic surgery in a sarcopenic patient: a case report
This case report demonstrates that a structured non-operative protocol involving focal counter-pressure, low-pressure venting, and pressure suppression can successfully achieve complete spontaneous reduction of an acute incarcerated port-site lung hernia in a sarcopenic patient, offering a safe alternative to urgent surgical reconstruction.

The human chest is a remarkably sturdy cage, designed to protect the delicate lungs while allowing them to expand and contract with every breath. This protection relies on a complex layering of ribs, muscles, and connective tissue that holds everything in place. However, when this structure is weakened by age or disease, or when it is subjected to sudden, violent forces, the integrity of the cage can fail. In rare instances, a piece of the lung itself can push through a gap in the chest wall, a condition known as a lung hernia. While this is sometimes caused by severe trauma, it can also occur as a complication of minimally invasive surgery, where small incisions are made to remove lung tissue. The question of how to treat such a hernia, especially in an elderly patient with fragile muscles, has long been a point of debate. Traditionally, doctors have believed that once the lung is stuck outside the chest, the only safe option is to rush back into the operating room to sew it back in. But this approach carries its own risks, particularly for patients who are already weak.
This case report tells the story of a seventy-one-year-old man who faced exactly this dilemma. He had undergone a successful surgery to remove a small tumor from his left lung using a video-assisted technique, which involved making three small cuts in his chest rather than one large opening. The surgery went smoothly, and for the first few days, he recovered well. However, on the fourth day, shortly after a drainage tube was removed from his chest, he experienced a sudden, violent coughing fit. This burst of pressure forced a section of his lung to bulge out through the hole where the surgical tools had entered, creating a painful, visible lump on his chest wall. The situation was complicated by the fact that the man had a condition called sarcopenia, a form of age-related muscle wasting that had left his chest wall muscles unusually thin and weak. When doctors first tried to push the lung back inside, it would not stay. They then attempted a standard medical maneuver: they intentionally let air into the chest cavity to make the lung shrink and collapse, hoping the lung would slip back in on its own. Surprisingly, this did not work. The lung tissue had become swollen and stuck, trapped by a tight ring of muscle and tissue that acted like a constricting collar, holding the lung firmly in place.
Instead of immediately returning the patient to the operating room, the medical team decided to try a carefully planned, non-surgical approach. They realized that because the lung was not dead or dying, they had time to let the swelling go down naturally. They placed a thick, firm pad of gauze directly over the bulging area and wrapped the patient's chest with an elastic bandage to apply steady, gentle pressure. This external pressure helped to counteract the internal forces pushing the lung out. At the same time, they kept a small tube in the chest to gently release any air or fluid that might build up, preventing sudden spikes in pressure. They also gave the patient strong medication to stop him from coughing or straining, ensuring that no new forces would try to push the lung out again. Over the next several days, the team monitored the patient closely with repeated scans to watch the lung and the swelling. Slowly, the swelling in the trapped lung tissue subsided. As the tissue became less swollen and the muscle spasm around the opening relaxed, the lung was finally able to slip back inside the chest cavity on its own.
By the twelfth day after the incident, the lung had completely returned to its normal position inside the chest, and the chest wall had healed. The patient was discharged sixteen days after the surgery, fully recovered and without the need for a second, more invasive operation. This case demonstrates that for certain patients, specifically those who are stable and do not have signs of the lung tissue dying, a structured, conservative treatment can be just as effective as surgery. The key was recognizing that the lung was stuck not because it was permanently damaged, but because it was swollen and held tight by a muscle spasm. By managing the pressure and waiting for the swelling to go down, the doctors allowed the body to heal itself. The report also highlights the importance of identifying patients with weak chest muscles before surgery, as their bodies may not be strong enough to hold the incision closed against the force of a cough. It suggests that in the future, surgeons might need to use stronger stitching techniques for these vulnerable patients to prevent the lung from ever pushing out in the first place. Ultimately, this story shows that sometimes the most effective medical intervention is not to cut, but to wait, protect, and support the body's own ability to recover.
