[Medical Human Story: Episode 61]-At the Brink of Breath, Unseen Pressure_3
Part II: The Direction of Pressure
Pressure Always Moves Toward the
Weakest Point
I stood once again in front of the CT
screen.
The right lung, upper lobe.
A small, irregular nodule.
It was not just a shadow.
It was a structure with meaning.
“The chance of this being
incidental is low.”
I called the resident over.
“Do you see this?”
He leaned closer.
“Yes… it looks like a nodule.”
I spoke slowly.
“The problem is the shape.”
A Lesion with Blurred Margins
Does Not Lie
Benign nodules usually have well-defined
borders.
But this was different.
The edges were irregular
It subtly blended into the surrounding
tissue
Fine spiculation was present
I murmured to myself.
“This… is highly suspicious for
malignancy.”
Another Reason He Couldn’t
Breathe
Kim Doyoon’s dyspnea might not have been
caused by pneumothorax alone.
If that nodule was malignant—
his lungs were already fighting on two
fronts:
Structural destruction (COPD + bullae)
Cellular rebellion (cancer)
“Thoracic surgery has
responded.”
The surgical resident arrived.
“I’ve reviewed the patient. Given the
persistent air leak, we should consider surgery.”
I nodded.
“I agree. But…”
I pointed at the CT scan.
“We need to address this as well.”
Surgery is both a treatment and a diagnosis
The thoracic surgeon studied the screen for
a long moment.
Then he said briefly,
“We can handle both at once.”
That meant—
Bullectomy
(removal of bullae)
Simultaneous tissue biopsy
“But can the patient tolerate
it?”
That was the real issue.
Kim Doyoon was already:
Hypoxic
With reduced lung function
In an acute condition
I Reassessed His Breathing
His SpO₂ had risen to 94%.
But it was still unstable.
From the chest tube, bubbles continued to
rise.
The air leak persisted.
“We don’t have time.”
I had to make a decision.
Pressure Changes
Direction
In tension pneumothorax, pressure fills the
thoracic cavity.
But now—
that pressure was acting in another way.
Everything was pressing against each other.
“Let’s proceed with
surgery.”
I said it.
Short. Clear.
A Brief Conversation Before
Surgery
I approached the patient.
He was still wearing an oxygen mask.
His eyes were clearer now.
“Mr. Kim, can you hear
me?”
He nodded weakly.
“There is a problem with your lungs. You
need surgery.”
A moment of silence.
Then, with effort, he asked—
“…Do I… have to?”
Doctors Sometimes Have to Deliver
Cruel Choices
I looked into his eyes and said,
“If we don’t do it now, it could become
more dangerous.”
This was not an exaggeration.
It was the truth.
He Closed His Eyes, Then Opened
Them
And said—
“…Please…”
The Road to the Operating
Room
The stretcher began to move.
Watching him, I thought:
Every human being walks the same path in
the end.
But the speed of that journey—
sometimes, we decide it.
The Operating Room — Another
Battlefield
The operating room is always different.
“Induction of
anesthesia.”
The anesthesiologist spoke.
The patient’s consciousness slowly faded.
I watched him.
VATS — A Technique to See the
Invisible
Video-Assisted Thoracic Surgery.
I fixed my gaze on the monitor.
And then—
“Confirmed. Bullae
rupture.”
The lung on the screen was more damaged
than expected.
A massive bulla.
And the rupture site.
Air was leaking out.
<h2>But That Was Not the End of the
Problem</h2>
The surgeon said,
“Let’s check the right side as well.”
I held my breath.
The Camera Turned to the Opposite
Lung
And in that moment—
I knew.
That Nodule Was Not an
‘Incidental Finding’
A small lesion.
The surgeon spoke.
“…Proceeding with biopsy.”
Two Battles Were Unfolding at the
Same Time
On one side:
Removing the air
Restoring the lung
On the other:
Obtaining tissue
Diagnosing the future
A Thought Crossed My
Mind
The Surgery Was Successfully
Completed
Bullae removed
Chest tube maintained
Biopsy in progress
The patient was transferred to the
intensive care unit.
But the Story Was Not
Over
The real problem had only just begun.
I Stood Outside the Intensive
Care Unit
I looked at him through the glass.
His chest was moving with the assistance of
a machine.
His Breath Had
Returned
no one knew yet.
The Results Would Come in a Few
Days
The biopsy.
I Asked Myself Again
What are we fighting right now?
cancer?
And I Waited for the
Answer
Doctors always want to know.
