A Physician’s Clinical Diary-Episode 46: The Garden of Ice and the Solar Probe—The Miracle of CCHTS(3)

 

The Miracle of CCHTS


Symphony of Ice and the Solar Probe

The air in Operating Room 7 was exceptionally cold and sharp, perhaps due to the liquid nitrogen tanks maintaining sub-zero temperatures. The intense glare of the surgical lights precisely illuminated Seong-jin's abdomen on the operating table. Surrounding him, a battery of monitors played the rhythm of life, charting his heart rate, blood pressure, and oxygen saturation in real-time.

"Beginning surgery."

Kang Min-woo’s voice was lower and firmer than usual. In his hand, he held the CCHTS (Combined Cryo-Hyperthermia Therapy System) probe, the centerpiece of this operation. This slender metal rod, barely 2mm thick, was more than just a tool. It was the sole lance destined to strike a slender tumor stretching 15cm through Seong-jin’s body.



Phase 1: First Insertion into the Abyss

Staring at the ultrasound guidance, Min-woo pushed the probe into Seong-jin’s upper right abdomen. It pierced the skin, passed through the liver tissue, and finally reached the distal part—the deepest tip of the tumor.

"Position locked. Initiate first cryo-cycle."

A low mechanical hum rose from the equipment upon his command. Liquid nitrogen at $-145^{\circ}\text{C}$ began to flow through the probe. On the monitor, the tip of the tumor turned white as it froze. The white sphere on the ultrasound—the Iceball—expanded slowly, like a snowflake blooming in the dark.

"Iceball diameter secured at 2.5cm. Maintaining a 1cm freezing margin beyond the tumor boundary for complete cell death."

Beads of sweat formed on Min-woo’s brow. The first iceball was a success, but this was only the beginning. The tumor was too long. Conventional methods would have required inserting five or more additional probes, but Min-woo moved to the next stage to demonstrate the true value of the CCHTS.

Phase 2: Solar Warmth—Heat and Retraction

"Stop freezing. Switch to Hyperthermia mode."

This was the decisive moment that set the CCHTS apart from traditional cryosurgery. Normally, once an iceball forms, the probe becomes frozen solid to the tissue, making it immobile; any forced pull would cause catastrophic trauma by tearing the surrounding tissue. However, as Min-woo pressed the heating button, the internal high-frequency heater surged in temperature.

"Periprobe thawing confirmed. Moving position."

The probe, once locked in ice, slid smoothly backward, retracting 3cm along its original entry path. On the monitor, a surreal sight unfolded: the first iceball remained frozen solid while the probe glided out of it like a ghost. This was the essence of the "Single Puncture, Multiple Ablations" strategy.

Phase 3: Linking the Chains of Ice

"Initiate second cryo-cycle."

Freezing began anew at the new position. As the second iceball formed, it began to overlap with the tail of the first. The two white spheres merged as if pulling toward one another, forming a long oval.

"Look at this. The iceballs are connecting. Like a chain of life," the assisting surgeon remarked in awe.

Min-woo did not stop. Heat, retract, and re-freeze. This precise rhythm repeated like variations in a classical symphony. The third and fourth iceballs formed in succession, swallowing the body of the tumor. The massive 15cm tumor was now trapped within a single, elongated Slender Iceball, undergoing silent necrosis.

Phase 4: Crisis and Control

As the surgery passed its midpoint, a sudden alarm shattered the silence. The temperature of a major blood vessel near the tumor was dropping rapidly. The iceball had grown larger than expected, threatening the function of a vital artery.

"Heart rate climbing! Detecting fluctuations in blood pressure!" the anesthesiologist shouted urgently.

Tension gripped the room. It was a hair-trigger situation where a slip-up could lead to massive hemorrhaging from vascular damage. Yet, Min-woo remained calm. He utilized the CCHTS’s heating function for localized precision control, subtly raising the temperature only near the vessel.

"Fine-tuning heat output to 15%. Maintain the freezing margin, but prevent icing on the vessel wall."

Min-woo’s fingertips delicately manipulated the dials. On the monitor, the vessel's temperature began to drift back into the safety zone. By sacrificing multiple probes to minimize mechanical trauma, he was now exerting intense focus to control every variable with just this single probe.

Phase 5: The Completed Garden of Ice

Finally, the fifth and final cycle concluded. From the head of the tumor to its tail, a perfect pillar of ice had been constructed along a single insertion path. It stood like a transparent, solid rampart within Seong-jin’s body.

"Freezing complete. Confirming final iceball morphology."

The imaging confirmed that the entire tumor was perfectly contained within the "Killing Scope" of below $-40^{\circ}\text{C}$. There were no irregular freezing zones or blind spots—issues often seen with multiple probes. It was the maximum result achieved through a single puncture and minimal invasion.

"Removing probe. Final heating."

Min-woo thawed the probe completely and withdrew it gently. In the wake of the surgery, only a tiny 2mm dot remained. In a conventional operation, this site would have been a scene of blood-soaked gauze and numerous sutures. Min-woo paused his trembling hands for a moment and listened to Seong-jin’s heartbeat, which had returned to a steady rhythm. It was the warm, wondrous victory of life following a struggle in the bitter cold.


To be continued.
