Zheng Ren began to separate the anterior rectal wall and the lateral rectal ligaments on both sides. The ligaments were broken. After ligation, Zheng Ren felt a little uneasy. He was afraid that the ligation line would fall off after the edema was eliminated and sewed again.

Then he separated the rectum to the levator ani plane. The retrorectal peritoneum was cut to extend to Douglas fossa, then the anterior rectal serosa was cut, and the bilateral lateral rectal ligaments were removed.

"It's really troublesome. You must protect your anus. You can't sew it directly." Su Yun finished brushing his hands again, disinfected and spread the list, called Quan Xiaocao to help him, and kept nagging.

At this time, Zheng Ren's action slowed down.

He hesitated and lost his lightning speed.

The speed suddenly dropped, and even Feng Jianguo felt a little awkward. This should be the first time he has seen boss Zheng perform surgery.

"Boss Zheng, it's hard to choose where to cut the intestine?" Feng Jianguo asked carefully.

Zheng Ren nodded.

This is indeed the biggest problem he has encountered.

Looking at the intestinal tract after the impact of huge water pressure, it is similar to being injured by blast. Not to mention the location of the breach, just serious congestion and edema made it difficult for Zheng Ren to make a choice.

Although he has made nearly 30 attempts in the system operating room, Zheng Ren still failed to find a reasonable way to solve the condition of the injured at present.

"Boss Zheng, cut as much as you can." Feng Jianguo whispered, "cut more intestines as much as possible under allowable conditions..."

With that, he couldn't go on.

If you cut more, total intestinal resection, but that's impossible!

Zheng rengen didn't listen to Feng Jianguo's suggestion. He hesitated for a moment, and a new idea appeared in his mind.

Immediately go to the system space, click to buy the operation training time and enter the system operating room.

Although always thinking of having operation training time, you can choose and try more when you encounter problems during operation.

But this is his first time in surgery.

Including the technical barrier of hepatobiliary surgery - autologous liver transplantation, including abdominal cocoon disease, Zheng Ren has never done so.

The patient on the operating table is seriously injured!

It is difficult for Zheng Ren to find a thorough solution to the problem in a short time.

After coming in, the operation was the same as the process outside, but there were no Xie Yi, Feng Jianguo, Su Yun and Quan Xiaocao.

Instead of using a microscope, Zheng Ren began to cut his intestines.

Because of the unevenness of intestinal blast injury, the patient's intestinal tract is good and bad. Zheng Ren had a whim. Can he mend and let the patient live?

He began to try.

The congested intestines were removed, and the remaining intestines were left for local anastomosis. When it comes to the location of the superior mesenteric artery, Zheng Rencai used a microscope for vascular reconstruction.

Sections of the intestine were removed, and the remaining intestine was repaired and blood vessels reconstructed.

Zheng Ren feels that the level of his general surgery science and technology tree is a little insufficient. Although it is a master level, and it is not the master level in the early stage, he still feels very difficult.

Without hesitation, add all the accumulated skill points to the skill tree of general surgery.

Looking at the progress bar, Zheng renslightly was a little satisfied.

But that's not enough.

It is not only a general surgical skill, but also involves vascular reconstruction. Finally, Zheng Ren can only use a master level skill book to improve the surgical level of vascular surgery to the extent that he can complete the operation.

In the system operating room, Zheng Ren made an attempt that no one else had done, almost regardless of the passage of time.

The repaired intestines are like broken clothes. It's terrible.

……

……

"Boss Zheng? Why don't we open up a section of intestines and do it in 3-5 days..." Feng Jianguo is still thinking about what to do.

Zheng Ren suddenly said, "I think it's better to do intestinal segmental resection and anastomosis combined with superior mesenteric artery reconstruction."

"Superior mesenteric artery reconstruction?" Feng Jianguo was surprised, "do you want to find Director Mao? Director Mao estimated that he would also like to reconstruct the superior mesenteric artery..."

"No, that's what I think. Try it." Zheng Ren finished, lowered his head again, stretched out his hand and patted the hemostatic forceps in his hand.

Feng Jianguo can't keep up with Zheng Ren's thinking.

The operation continued. After su Yun repaired the perianal position, he returned to the operating table, took off his clothes, asked for a microscope for vascular surgery, and brushed his hands on the stage again.

Microscopic reconstruction of superior mesenteric artery. The boss wants to try this operation. It seems that he is really in a hurry.

Is this a dog jumping off the wall? It should be that Su Yun hurried to brush his hands and change his clothes again while feigning Zheng Ren.

After brushing his hands, Su Yun was also impolite. He stood beside Feng Jianguo and pushed him aside.

Feng Jianguo did not resist, nor was he unhappy. He was even relieved.

Boss Zheng's operation is too high-end. Don't say help yourself. I can't even understand it. The top technical standards of the two departments of general surgery and vascular surgery are used in one operation. Feng Jianguo has long been dazzled and sees double shadows.

It seems that boss Zheng is still young. He doesn't look good enough to perform microsurgery on his body.

When Su Yun came on stage, the operation speed was significantly accelerated.

Zheng Ren feels it's better to have surgery outside. The loneliest thing in the world is to have surgery alone.

It doesn't count to do an operation alone, but also to do a very difficult operation alone.

With an assistant, the operation is much simpler. He is sure that the completion of the operation will be higher than that given by the big pig hoof in the system operating room.

Feng Jianguo looked at the operation area. The light of the shadowless lamp was so dazzling that the problem of dazzle was even more serious.

He can only raise his head and look at the distance as far as possible to alleviate the fatigue of the upper rectus, lower rectus, inner rectus, outer rectus, upper oblique and lower oblique muscles.

The lead door of the operating room opened and Ringer came in.

"Boss Zheng, I'm busy." Ringer smiled and didn't seem to think it was a big thing at all.

"Director Lin, I'm almost crying. Don't laugh." Feng Jianguo's eyes were sore and said with a bitter smile.

"What are you crying about? You still cry when boss Zheng is there?" Ringer road.

"Boss Zheng has also encountered problems." Feng Jianguo said astringently.

"Oh." Ringer's expression remained the same, and he didn't see any tension and panic.

"Director Lin, this time it may cause trouble for your medical office." Feng Jianguo said.

"What's the trouble?" Linge said, "if boss Zheng can't solve the problem, I don't believe anyone in the whole empire can do it."

“……”

"Do your best and listen to fate. Do you really want to live the dead and cure bones? That's bullshit. Boss Zheng can't do the operation, that's the patient's birthday." Ringer said firmly.

Feng Jianguo felt his eyes slightly moist. He tried to keep his eyes open and keep his tears from falling.

Really special!

Is this the director of the usually strict medical department?!
