Surgery for an airway tumor preserved his entire left lung

Daniel asked the surgeon to point to the tumor once more.

It sat inside the airway leading to his left lung, close to the fork where air passes into the upper and lower lobes. The tumor extended into the openings of both branches.

“If you cut that part out,” he asked, “what happens to the lung beyond it?”

At 63, Daniel liked to walk. Since retiring, he sometimes met former colleagues, and if the distance was manageable, he preferred to leave early and go on foot. He had never thought much about the work his lungs did. Walking, climbing stairs and talking along the way had been unremarkable parts of his day.

Now he wanted the cancer removed, but also wanted to understand what life after the operation might be like.

A dry cough had brought him to Shanghai Chest Hospital. A chest CT showed a lesion in the left main bronchus, the main airway entering the left lung. Bronchoscopy allowed the doctors to examine it from inside. They could see that the tumor involved the entrances to the upper- and lower-lobe bronchi. A biopsy confirmed squamous cell carcinoma.

Daniel had several questions: could it be operated on, how soon, and how much would have to be removed? When he sat down with the doctor, another question came first.

“Have you found it anywhere else?”

PET/CT showed no evidence of lymph node involvement or distant spread. That was reassuring. The difficulty was the tumor's position.

The fork it occupied is called the left secondary carina. Removing the affected section would leave the main airway disconnected from the two branches serving the lung. To preserve the lung tissue, the surgeons would have to reconstruct that junction.

After assessing his heart and lung function, the thoracic surgery team planned a robot-assisted thoracoscopic resection and reconstruction of the left secondary carina.

They explained the sequence. First they would remove the involved part of the airway. Then they would join the upper- and lower-lobe bronchi to form a new fork, and connect that fork to the left main bronchus.

Daniel listened carefully. Until then, he had thought of cancer surgery mainly in terms of what had to be cut away. He began asking how the doctors would know the margins were clear and how the remaining airways could be joined.

Preserving lung tissue depended on removing the tumor adequately. During the operation, the team would examine the cut edges of the airway for cancer and assess the relevant lymph nodes.

His family wanted the tumor dealt with as soon as possible. He did too. But he was also thinking about whether he would need to stop and rest during a walk, whether someone would have to accompany him whenever he went out, and how much he could still manage on his own.

These questions did not make him delay treatment. He wanted to understand the operation before agreeing to it.

The word “robot” prompted more questions. At first he pictured a machine that performed the surgery itself. The surgeon explained that a doctor remained in control. The system provided a magnified, three-dimensional view and instruments that could turn precisely within the limited space of the chest.

That mattered near the root of the lung, where major blood vessels lie close to the airway. The team needed to separate those structures, remove the affected airway and place the reconstruction sutures accurately.

On the day of surgery, Daniel was under general anesthesia while the surgeons dissected the relevant lymph nodes and freed the far end of the left main bronchus and the beginnings of its two branches. They removed the section containing the tumor.

Rapid pathology examination found no cancer at the resection margins and no metastasis in the lymph nodes examined.

The surgeons then joined the upper- and lower-lobe bronchi to create the new fork and sutured it to the left main bronchus. Once the connections were complete, they checked for air leaks and inspected the joins with a bronchoscope.

Both lobes of the left lung had been preserved.

When Daniel woke, that was the result he wanted to hear. His family told him that the affected airway had been removed and the remaining sections reconnected.

“Both parts are still there?”

They were.

He still had a chest drain, and the reconstructed airway needed time to heal. It was too early to know how far he would be able to walk or how fully his exercise capacity would recover.

For the moment, he paid attention to the next step: what the doctors said on their rounds, how he felt that day, what needed to happen before he could go home. He tried not to judge the whole outcome from a single breath or movement.

His postoperative course was uneventful. Final pathology confirmed squamous cell carcinoma, with clear margins and negative lymph nodes. The chest drain was removed, and he was discharged on the seventh day after surgery.

As his family packed, he went over the discharge papers once more to make sure he understood the follow-up arrangements. The healing of the airway, his lung function and any signs of recurrence would all need further attention.

For now, he knew exactly what the surgery had achieved: the tumor-bearing airway junction had been removed and rebuilt, and his entire left lung remained in place.

At the ward door, a family member took his bag. Daniel let them carry it. Whether he could walk to meet his old colleagues again was something he would find out as he recovered.
