Chapter 304: 0298 Continuous Failures (2/4)

"Really simple and brutal." Su Yun, during the break, also interjected: "For a world-renowned professor, couldn't you be a bit more tactful?"

"Heh." Zheng Ren interrupted Su Yun with a bored "heh," then picked up the phone to call Xie Yiren and Chu Yanran to arrange preoperative preparations for the Shou Bing.

After hanging up, Zheng Ren called Feng Xu Hui to confirm that side had a full set of TIPS Surgery equipment, and urged again to send it over as soon as possible.

Finally, Zheng Ren called Director Pan to explain the situation.

After finishing all the calls, Zheng Ren and Su Yun had already arrived outside the Operating Room.

Changing clothes, they remained silent.

The patient hadn't arrived yet, and Zheng Ren wasn't in a particular hurry; seeing Su Yun finish changing into the Isolation Gown, he took out a cigarette case and said, "Go help with the preparations; I'll have a smoke."

Having a smoke before surgery to calm the nerves is common practice. Su Yun acknowledged and went to the Operating Room.

Zheng Ren arrived at the small smoking room, lit a Zi Yun cigarette, took a deep drag, and then entered the System Space.

Without hesitation, Zheng Ren exchanged all his reward time and Experience Points for Surgical Training Time.

The System Operating Room rose up from the ground, and the experimental subject was ready.

Zheng Ren began training the Shou Bing.

Jugular vein puncture presented no difficulty.

The guide wire passed through the jugular vein into the heart, then to the hepatic vein, also without difficulty.

Compared to the capillary arteries of prostatic hyperplasia, this venous route is like an eight-lane highway alongside a rough, muddy country path—it's not too spacious.

But the difficulty lay ahead.

The puncture needle entered; Zheng Ren estimated the length and distance, then began puncturing.

Failure...

Changing position,

Failure...

Changing position again,

Failure...

After dozens of attempts, it was impossible to penetrate the hepatic vein and locate the branch of the portal vein within the liver.

So difficult...

Really so difficult...

Truly a pearl on the crown...

After the forty-second failure, Zheng Ren stopped.

Although Surgical Training Time is precious, continuing blindly like this yields limited effect.

The portal vein is relatively wide; even its branches are quite wide.

However, accurately locating the portal vein's branch within the hepatic vein and ensuring a successful puncture cannot rely on luck alone.

But... what technique is still needed?

Zheng Ren quickly searched his memory for various documents he had read.

Dozens of puncture failures would not cause the patient to die suddenly.

The puncture needle is not thick; the liver is a solid organ, and the damage from the needle tract can be quickly staunched by pressure generated from the liver tissue itself.

But if there were many more failures... the liver might end up being riddled with holes by the puncture needle.

The approximate tolerable upper limit of failures is 20–30 times.

In other words, the puncture needle offers at most 30 chances to rely on luck. No wonder the global average surgery time is 4 hours and 23 Minute—everyone is just playing the odds.

If facing a real patient rather than an experimental subject in the System Operating Room, Zheng Ren wouldn't dare to proceed so recklessly.

Better to first review the materials, treating it as sharpening the knife.

After all, sharpening the knife does not delay the woodcutter's work.

Zheng Ren left the System Operating Room and began reviewing the various materials in his mind.

The documents and materials he had seen in the library before now appeared with perfect clarity as his thoughts flowed, effortlessly.

His grandmaster-level interventional expertise also played a major role while silently reading the documents; many places Zheng Ren previously couldn't understand now seemed simple and clear.

Moreover, with his rich experience in liver anatomy, Zheng Ren quickly gained a large amount of experience in TIPS Surgery.

These experiences were forged by predecessors through repeated failures, one life at a time.

Although that is so, the System Operating Room has a few drawbacks.

Namely, time is pressing; every minute and second is earned by completing tasks, and when the time is up, the system will surely kick Zheng Ren out, leaving no room for negotiation.

Furthermore, here only Zheng Ren himself exists, without a mature instructor to teach and pass on experience.

Everything can only rely on Zheng Ren consulting documents and figuring things out on his own; many experiential sensations cannot be written into literature, which Zheng Ren knows.

At the fastest pace, Zheng Ren integrated the entire TIPS Surgery process with liver anatomy, recording every piece of experience mentioned in the literature, whether success or failure.

Subsequently, Zheng Ren switched to a different experimental subject.

After dozens of failures, the previous experimental subject could no longer be used.

Jugular vein puncture, entering the hepatic vein, began the puncture needle puncture.

Failure...

Failure...

Failure...

Damn!

Zheng Ren nearly went mad.

Actually, this time he already had some confidence in his mind. After all, TIPS Surgery was initially a joint effort between the Interventional and General Surgery Department.

Zheng Ren himself, with grandmaster-level interventional skill and master-level General Surgery Department expertise, being doubly specialized, is extremely rare worldwide.

Among these, especially with liver dissection experience, it was equivalent to a few hundred or thousand cadaver teachers being squandered by Zheng Ren alone. In the real world, this could never happen.

But……this still won't do, just how difficult is the TIPS surgery?!

Impossible!

Zheng Ren's first thought was to deny that he couldn't do it.

If I can't do it, probably nobody can.

It must be that time is pressing and I took the wrong path.

What exactly is wrong?

Zheng Ren waved his hand, and the operating room disappeared.

The surgery time is limited, he cannot waste it. But the time outside……is even more limited, the patient will soon be placed on the operating table.

He sat quietly beside the small pond, watching the lifelike little fox sink into thought, recalling each step of his surgery, seeking possibilities for improvement.

After a few minutes of contemplation, suddenly a wave of pain came.

Zheng Ren hurried out of the system operating room, and tossed the cigarette butt that was burning his fingers.

He thought it over, then called Su Yun, asking him to contact Feng Xu Hui, to have Su Yun accept the supplies and not disturb him. When the patient arrives, prepare to start the surgery, and when to call him.

Su Yun somewhat didn't understand, but facing the emergency surgery, he did not question Zheng Ren's decision.

After hanging up, Zheng Ren cherished every second, and entered the system space again.

What exactly is wrong?

Zheng Ren quickly reviewed the surgical procedure; the only difficulty was that the puncture needle, inside the portal vein, was affected by blood flow, interfering with his judgment.

Then how about starting from imaging?

CT? Nuclear magnetic resonance?

Zheng Ren suddenly recalled the passive ability—fusion—gained after completing the second stage of the 【Initial Reveal of Sharp Edge】task.

Perhaps this is it?

He prepared to give it a try.

The experimental subject prepared by the system was very thoughtful, with all kinds of examinations available.

Zheng Ren entered the surgical training room; this time he didn't rush to perform surgery, but began reading the patient's CT and contrast-enhanced nuclear magnetic resonance images.

Surgical training time trickled by, but Zheng Ren did not stint.

Sharpening the knife does not delay the woodcutter.

Several hours passed, and a glint of enlightenment flashed in Zheng Ren's eyes.
