Zhang Fan looked at the severed ends of the two large intestines. It was like a chicken that had been hit by a lead ball and was bleeding from a tube to a flat object. He sighed deeply. This thing is too difficult to say.

Simple and simple.

Suturing is relatively difficult. In the past, there were three difficulties.

The first difficulty is arterial suturing. In the early years, arterial suturing was more difficult. This task is short in time and requires high requirements. People who failed to sew three times died. Therefore, the requirements for doctors are relatively high.

The second difficulty is suturing nerves. In the past, the equipment was not good, so the difficulty of suturing was much lower than that of arteries. After all, nerves don’t bleed!

But it is different after suturing. You can see whether the blood vessels are leaking or not.

But the nerves are different. You have to wait for several months to recover before you can see them. Often the effects are gone and they can grow into neuromas. Painful patients twitch, just like Nicholas Zhao Si’s face.

Same as pumping.

The third difficulty is suturing the gastrointestinal tract.

Now we have added facial suturing. In the past, facial suturing and other things could be left to the apprentices to practice. But now it is no longer possible. If the suturing is not good, the patient will have to fight the doctor with a knife.

Of course, this also reflects the progress of the country. Otherwise, if the people don't have enough to eat, who would worry about whether there are scars on their faces.

With the development of surgical equipment, especially the improvement of microscopic equipment, neurovascular suturing is no longer as difficult as before.

There is no need for doctors to grab a dog, break its leg, and then try to stitch it up. The yellow dogs on the street will run like crazy when they see the man in the white coat.

Gastrointestinal suturing has not made much progress from thirty years ago to now.

Because the human body is very strange. For example, when it comes to cancer, there is a saying that the outcome of inflammation is either cure or cancer.

And there is another type of cancer, which is metaplasia.

How do you define this thing? It is a mature cell that wants to become another mature cell.

And this kind of change usually occurs at the connection between two organs. To put it simply, it is like a man who was raised as a girl since he was a child. When he grows up, he feels that he wants to transform, and then he undergoes surgery.

To be honest, this thing has everything it needs when it transforms. Guan Guan turns into a hole, but its life is consumed and its body is hollowed out. It was young and died long ago.

The same goes for cells, especially at the junctions between organs. It's not just people who want to become another gender.

The same goes for cells.

But this kind of change is often determined by innate genes. If you want to change, you are going against the entire organism. You are rebelling.

Can body organs let you go?

All kinds of immune cells come directly with guns and cannons. This is inflammation. Once they are beaten, you will feel all kinds of aches and pains.

This kind of inflammation starts to become quite frequent when people are almost thirty years old. From time to time, ulcers or something like that appear inexplicably, such as oral ulcers.

Especially in certain age groups such as thirty-five, forty-nine, seventy-four, etc., outbreaks are particularly frequent.

According to the old folk saying, at seventy-four or eighty-five, the King of Hell does not ask you to go. In fact, the decline of human body functions does not decline linearly, but in a leaping manner. From thirty to thirty-five, the decline speed is slightly faster than that of two

The decline was a little faster when I was in my teens.

But it's not much faster.

But when you reach thirty-five, you immediately fall off a cliff, and then slowly decline again, and when you reach seventy-five, you fall off a cliff again. For example, when you were in your early thirties, you could do it seven times a night, but when you reached thirty-five, you were young.

The little wife grabbed her pants and chased him all over the floor.

Before the age of seventy, you can stand up to pee your shoes without peeing, but after seventy-five, it is often difficult to take it out. If you don't pee your crotch, you are already a hero!

This is a sign of significant decline in function.

A significant decline in human body functions often leads to a decline in the immune system.

Then the immune cells suddenly cannot defeat these rebels who want to rebel and become other cells.

At this time, the rebellious cells undergo metaplasia and transform into other cells.

As a result, the transformation failed and turned into cancer.

For example, portal cancer at the junction of the esophagus and stomach mostly occurs in people aged thirty-five.

For example, the connection between the cervix and the guide, cervical cancer.

Duodenal gastric cancer, which is the junction between the stomach and intestinal tract, has a high incidence among people aged thirty-five.

There are also bone cancers caused by this kind of metaplasia at the connection between hard bone and cartilage.

Therefore, most cancers, especially malignant cancers, often occur at the connections between organs.

If a person wants to change his gender, it is like a cell trying to metamorphose. The outcome will not be good.

Just like the taste of large intestine is obviously different from that of small intestine, meat and meat are different. It is too difficult to transform.

The same is true for the suturing of the intestine. If the suturing is not done well, the cells connecting the large intestine and the small intestine will be restless. If the suturing technique is not good, the cancer will not escape.

Therefore, Zhang Fan had to take too many steps to sew up the intestines.

First of all, it needs to be polished.

That's right, it's just polishing, just like repairing a broken inner tube of a bicycle wheel. You need to polish the broken area first to make the edges of the rubber surface rougher.

Only then can the stick be firmly attached.

The suturing between the intestines is actually similar.

First, the capillaries at both ends of the intestine must be destroyed, not the large blood vessels. If the large blood vessels are destroyed, the intestine will directly die.

When capillaries are destroyed, their tissue structure is destroyed.

Then they are sutured, and when they heal, they will discuss with each other and finally reach an agreement to form unified cells and blood vessels.

If the microstructure is not destroyed.

After suturing, the small intestine grows from the small intestine, and the large intestine grows from the large intestine. Finally, two different cells appear in the same place, and then without even thinking about it, after time fermentation, this thing turns into metaplastic cancer.

Moreover, it occurs catalytically. Just like when you have an ulcer in your mouth, the doctor tells you not to smoke or drink alcohol.

The patient agreed in person and ignored her, saying that he should drink and smoke when he should. He also said that my grandfather smoked and drank for ninety-nine years.

Then, under the stimulation of tobacco and alcohol, the ulcerated cells and blood vessels were not intended to metamorphose, but they were suddenly seduced and transformed, and those who had no cows became cows and cows.

And suturing is another kind of catalyst.

Therefore, this kind of suturing of the small and large intestines requires considerable attention.

Like a craftsman, Zhang Fan rubbed the space between the two intestines for several minutes.

Zhao Yanfang almost went crazy.

Because Zhang Fan rubbed her a little too much.

Although she is not married, she has been in love.

Seeing Zhang Fan's technique, she seemed to remember something...

In fact, Zhang Fan is simulating it in the system in his mind.

"No, it's timed out!"

"No, my intestines are rotten!"

After trying again and again, Zhang Fan finally opened his eyes.

If it weren't for his shining eyes, Coach Zhao would really have thought that Zhang Fan had become a sage.

"Can you ensure that intestinal necrosis will not occur within three minutes of freezing, and can you ensure that the intestine can be extended?"

Zhang Fan stared at Zhao Yanfang, how could he be a sage? He was clearly looking like a tiger descending from the mountain, wanting to eat people.

Instructor Zhao is usually quite aggressive against Zhang Fan. Moreover, Zhang Fan knows that his scientific research is not very good, so he tends to shy away from Instructor Zhao.

But now, the piercing big eyes and the obvious perseverance of a male lion made Mr. Zhao stunned.

"Okay! But you have to be quick."

"Don't worry, I'm fast enough. Let's start!" Zhang Fan has already successfully operated the suturing method in the system.

Medical treatment actually has a template when it comes to common diseases. Medical guides for various departments compiled by major experts are collected every year.

In fact, it means telling doctors what the latest and best treatments for common diseases are. You don’t have to figure it out on your own, I’ve told you.

But at the high end, let alone guidelines, even if you bring in doctors to compile guidelines, you may not be able to have a unified treatment method.

Therefore, the more high-end a doctor is, the more he pays attention to individual treatment differentiation.

As soon as Zhang Fan spoke, Lao Zhao and Zhao Jingjin grabbed Zhang Fan's sterile-gloved hand.

"You have to think twice. The time is too short and the difficulty is too high. Once you start this kind of cryo-suturing, there is no way back. If necrosis occurs, it will be troublesome."

"Well, I understand!" Zhang Fan looked at Lao Zhao and nodded.

There was obvious disapproval on Lao Zhao's face.

Zhang Fan added, "Don't worry, I'm sure, you have to help me. Dr. Zhao is still a little lacking."

"Okay! Go all out!" Now that Zhang Fan has decided, even if Lao Zhao doesn't agree, he will still help.

This is the surgical team.

Zhao Yanfang wanted to speak, but didn't!
