Chapter 1657: with translation of chapter title

Xie Yiren was excited, holding the surgical box in her hand, treating it like a treasure.

"Zheng Ren, what surgery?" Upon meeting, Xie Yiren immediately asked.

"Heart surgery, there..." Before Zheng Ren could finish speaking, Xie Yiren happily hugged the surgical box and said, "Who should I contact to have the operating room personnel disinfect?"

"Uh..." Zheng Ren still wanted to explain the surgery's risks to Xiao Yi Ren, but seeing her excited demeanor, he held back.

Zheng Ren took the surgical box, handed it to Chu Nu Ang Sai's disciple, and instructed him to send it for disinfection.

Xiao Yi Ren felt a bit uneasy, but she moved her lips and ultimately said nothing.

"Boss Zheng, this surgical box of yours is truly a treasure," Lao He said with a smile.

"Fortunately, for some surgeries, using it can increase the success rate by about ten points," Zheng Ren said.

"Heart surgery, are there any special instructions?" Lao He said solemnly; this was the first time he was going abroad for surgery with Boss Zheng, and he absolutely could not allow any mistake!

Lao He thought to himself.

Those twin sisters had never gone abroad with Boss Zheng; I suppose this counts as getting ahead of them.

The more so, the more one must be careful and cautious.

Having taken the initiative, as Boss Zheng's overseas surgeries increase, my position becomes ever more important.

Until Boss Zheng forgets those twin sisters.

That seems unlikely; then I'll diminish their role, so that whenever a high-difficulty surgery arises, they'll think of me.

Thinking this, Lao He looked at Zheng Ren and Xie Yiren with a somewhat complex gaze.

The most impressive thing about Boss Zheng's partner is that his girlfriend seems not to mind the existence of those twin anesthesiologists.

The capable can do anything; this is proof!

If it were me, I'd have already been beaten to death by my own wife.

"The surgery requires cardiopulmonary bypass. Also, the depth of anesthesia... I'll remind you during the operation." Zheng Ren, calculating the mucinous tumor or worm egg in the right atrium, said cautiously.

In theory, mucinous tumors and worm eggs should be easy to distinguish; imaging definitely shows a mucinous tumor, but Zheng Ren still considered the worm egg as an option.

Seeing Zheng Ren so cautious, Lao He felt a chill in his heart and said, "Alright, if there are any special needs during the surgery, just tell me one minute in advance."

After saying that, Lao He thought for a moment and said, "Boss Zheng, may I first familiarize myself with the machine?"

Not only does Lao He need to familiarize himself with the machine, but Zheng Ren and Su Yun also need to get used to the operating room environment.

Even a tiny difference can lead the surgery toward an unpredictable future.

At this point, being cautious is never excessive.

At this moment, in Zheng Ren's mind, Chu Nu Ang Sai is neither a gu master nor some emerging force of an ancient family fused with modern technology; he is merely a patient who needs surgery.

No matter how minor the surgery, one must give it their all, let alone a cardiac mucinous tumor, suspected to be a cardiac parasitic worm egg.

Chu Nu Ang Sai's disciple works efficiently, so Zheng Ren and the others need not worry; he had already arranged everything early on, even the doctor assisting at the operating table being the head of cardiothoracic surgery at the national hospital.

Upon arriving at the operating room, Zheng Ren explained the procedure he would perform—right atrial mucinous tumor excision under cardiopulmonary bypass with the heart still beating.

The head of cardiothoracic surgery at the national hospital was dumbfounded.

Cardiac tumors are encountered less than once a year; how did I happen to encounter one?

After explaining the procedure, Zheng Ren began inspecting all the instruments in the national hospital's operating room.

From the ventilator and ECG monitor all the way to the electrocautery and sutures, nothing was too big or too small.

The differences weren't significant, and Zheng Ren felt reassured.

It relates to equipment and consumables, but not absolutely; the most important factor remains the people.

With Xiao Yi Ren, Su Yun, and Lao He present, Zheng Ren will not face the embarrassing predicament he encountered in Xilin Town.

If he goes to unfamiliar places in the future, he should still interact with people more, Zheng Ren thought to himself.

"Lao He, any problems?" Zheng Ren asked with his hands behind his back.

"No." Lao He looked at the cardiopulmonary bypass machine and said, "It's not the newest equipment, but I've used this model before; there's no problem."

"Su Yun, any problems?"

Su Yun said nothing, raised her left hand, and made an OK gesture.

"Yi Ren?"

"Is the suture thread easy for you to handle? It's a less common model from Johnson & Johnson." Xie Yiren said.

Zheng Ren said: "No problem."

After saying that, he turned and told the national hospital's doctor: "Send the patient, prepare for surgery."

While that side was busy, Zheng Ren went to the side of the film viewer, positioned himself, entered the system space, and began surgical training.

A related surgery, I performed once on the mother of a friend of Zhang Weiyu in 912.

Although the location differs, it's largely the same.

If speaking purely of surgery, the difficulty of right atrial surgery is much less than that of tricuspid valve tumor.

After all, it doesn't involve valve replacement, so its complexity is lower by an order of magnitude.

Therefore, Zheng Ren dares to attempt the beating-heart mucinous tumor excision procedure.

Standing in the system operating room, Zheng Ren didn't rush into surgery but first steadied his emotions.

In the earlier altercation with Song En, Zheng Ren had gotten angry.

Now is a good time to calm down.

Recalling everything past, Zheng Ren felt that luck value still had an effect. This fortunate coincidence mainly stemmed from Su Yun wanting to have a meal with everyone from the medical team.

Bringing along Fan Tian Shui and the old class monitor, I didn't expect to avoid a calamity.

I hope the Big Pig Trotter will give me more tasks to increase luck value in the future; Zheng Ren smiled.

After all, I am a man with protagonist's halo and an extra +27 luck; under normal circumstances, there should be no problem.

After several minutes, Zheng Ren felt his emotions had stabilized.

He steadied himself and began the surgery.

Not concerned with the surgery completion rate in the system's operating room, Zheng Ren simply wanted to perform it once to see what was inside the heart.

Still, he went ahead step by step, making the incision, performing the surgery, and conducting the extracorporeal circulation all on his own.

Doing this does indeed waste some surgical training time, but these steps are also part of the surgery. Although it's hard to see a qualitative improvement, they remain extremely important.

After opening and exposing the heart, they found the patient's right atrium distended. Zheng Ren placed his hand on it and felt a slightly firm mucinous tumor inside.

Moreover, the patient's inferior vena cava was almost completely blocked.

Zheng Ren began establishing extracorporeal circulation, which was slightly different from the previous surgery; because of the inferior vena cava's condition, he opted to cannulate the femoral vein and the superior vena cava.

After cannulation, he tightened the superior vena cava control band, opened the inferior vena cava, and Zheng Ren incised the right atrium.

The tumor measured approximately 7.8 × 6.7 × 8 cm. It was horn‑shaped, extending into the inferior vena cava opening and the tricuspid valve opening, almost completely blocking the inferior vena cava. Below it lay a small stalk.

Like a large watermelon, the tumor floated within the right atrium.

The tumor's stalk lay between the inferior vena cava inlet and the right atrial wall, measuring about 1 cm in diameter.

Zheng Ren curiously examined the tumor tissue.
