The patient, a 65-year-old man, presented to the hospital with epigastric discomfort.

Gastroscopy revealed a redness and depression in the antrum, and pathological biopsy showed that it was high-grade intraepithelial neoplasia and local cancer.

Just the day before yesterday, the Department of Gastroenterology invited the Department of Oncology, the Department of Radiation Oncology, and the Department of Gastrointestinal Surgery to discuss together, and it was unanimously agreed that the patient met the characteristics of early cancer and was suitable for ESD surgery.

However, one of the difficulties in this operation is that the lesion is a bit large.

The oval lesion of about 7 cm * 4 cm, and the boundary is not clear, which makes all the doctors in the hospital have a little headache.

They have never had such a large area of endoscopic submucosal dissection.

As soon as Director Xiao gritted his teeth and stomped his feet, he was ready to go into battle in person to meet the challenge.

But the family seemed to hear the beating of the drums in their hearts.

The patient's son immediately said that he didn't have to work with the doctor in the hospital, and he would hire a famous doctor to come and make the knife himself.

Before he could contact him, Ai Yuan appeared.

His arrival was at the right time, and it perfectly solved the confusion between doctors and patients, so there was today's teaching operation.

Endotracheal intubation, general anesthesia. The anesthesiologist made a gesture and the operation began.

Ai Yuan skillfully operated the endoscope.

The endoscope has a handle, and there are various mechanism buttons on it, which is a bit like a gamepad in the shape of a rod.

Doctors generally hold the mirror axis with their right hand and use their left hand to control the "steering wheel" that rotates up and down, left and right, and the two hands cooperate with each other to complete various operations far away in the stomach.

As soon as Ai Yuan made a move, the observers in the classroom all held their breath and watched with full attention.

This is not only because of the other party's fame, but also because of the current way of teaching, so that they can't slip away at all.

Tomio's first classroom, which was renovated last week, has become a holographic substitute teaching.

Each observer is immersed in the scene, standing on the side of the operating table, to observe the operation up close.

In addition to not being able to get started with interaction, this teaching mode is many times stronger than before.

Every action of the chief surgeon, every word he says, and every change he handles are intuitively presented in front of the observers.

Director Xiao could see at a glance that Ai Yuan's gesture of holding the mirror was very different from his own.

Like many endoscopists, he likes to hold the handle with his ring and little fingers, and press the gas and suction buttons with his middle finger, but this is not the case with Ai Yuan.

He uses his thumb, middle and ring fingers to hold the handle of the endoscope in a position that controls it in the palm of his hand – the ring finger can touch any button on the top, bottom, left and right at any time.

His index finger is on the suction knob and his middle finger is on the gas rejecting knob to ensure that there is no delay when operating at the same time.

Director Xiao nodded frequently. It's no wonder that when I do ESD, I always have the feeling that I have more than enough energy and not enough energy, and it turns out that it is wrong from the gesture.

Sure enough, he is worthy of being an excellent doctor in Haishi First Hospital, and he has benefited a lot from just an endoscopic operation technique.

Tao Le has just done more than 300 ESD surgeries of the same type in the golden finger space, and when he looks at Ai Yuan's operation at this time, he has a deeper experience than Director Xiao.

The reason why she was able to achieve excellence after only making more than 300 units was naturally because she was already very familiar with the operation of endoscopes in the previous endoscopic retrieval battle, and it would naturally be much easier at this moment.

The operation of the endoscope is not only about the dexterity of the fingers, but also about adapting to local conditions, controlling the movement of the endoscope by adjusting the gas in the lumen, and applying techniques such as forceps to expose the field of view, so as to carry out more accurate treatment.

For example, if you want to drive an extended container truck, you can't just turn the steering wheel and step on the accelerator and brakes.

If you want to drive the car fast and steadily, and even turn flexibly, you have to go through a long period of training.

Ai Yuan has done nearly 200 ESD surgeries, and there are various types of ESD surgeries - higher than Director Xiao.

But if it is only for the patient in front of him, Tao Le's experience can throw him countless miles.

The surgery was carried out in an orderly manner. The lesion is labeled and injected submucosally to raise the lesion. Ring the lesion with a needle incision to mark the lesion.

Thirty minutes have passed since this step.

Next, it's time to cut and peel off.

Ai Yuan was about to do it, when he heard Tao Le say, "Doctor Ai, please wait a minute." ”

Ai Yuan attaches great importance to Tao Le's opinion. When he came to the first courtyard of Yunshi City, he originally came for her, but he immediately stopped when he heard the words.

"Doctor Tao, don't hesitate to mention any opinions?"

"I'll do an acupuncture first to stop the bleeding, and then you cut it open and peel it off." She said as she took out the disposable milli needle she had prepared.

Ai Yuan's pupils contracted instantly.

Acupuncture or something, he saw it at the operation last night, and he didn't know why at the time.

But now he knew, it turned out that its function was to stop bleeding.

Intraoperative acupuncture to stop bleeding? It's simply unheard of, can this work? Ai Yuan's mind was full of questions.

Not only him, but also the people who were holographically observing in the classroom.

Among them, that is, Director Xiao had heard a little rumor, and other people didn't know anything about it, so they didn't believe it at all.

This Xiao Tao didn't take this opportunity to study hard with Dr. Ai, but spoke loudly.

If acupuncture can stop bleeding, we have long organized and studied collectively, who cares if it is a means of traditional Chinese medicine or Western medicine?

What is useful is what is good, and doctors have always been pragmatic.

Tao Le didn't know, and he didn't care what they were thinking.

She pinned out like the wind, quickly pierced several acupoints around the stomach, and then motioned for Ai Yuan to continue.

The latter, without hesitation, uses a needle to cut the opening and then uses an IT knife to cut and peel.

With such a large wound peeling, bleeding is inevitable.

Intraoperative bleeding is the difficulty in ESD surgery.

The most commonly used method in clinical practice is coagulation with thermal biopsy forceps. However, bleeding often recurs, and after repeated coagulation, eschar will appear, causing the wound to harden, greatly increasing the difficulty of complete peeling.

But something magical happened. Wherever the IT knife passed, not a drop of blood oozed out.

Until the entire lesion was completely peeled off, revealing the huge muscularis propria at the bottom, the surgical field was still clean, and there was not even a drop of blood.

Seeing this, the spectators outside the demonstration room fell into a collective silence, followed by excitement.

Even in the holographic field of view, there are still many people who can't hold back and let out cheers.

Xiao Tao's hand is really handsome!

It's just a few needles, and if you simply insert it, you can't get a drop of blood out, what kind of fairy technique is this?

The older director and attending physician are just that, at most they are amazed, but the young man in Corey is so active that he has already thought of studying with a teacher.

Young doctors in the new era never thought about any unique skills, and they wanted to share learning when they saw new technologies.

We don't understand the complex acupuncture, so we want to learn this acupuncture to stop bleeding.

If you can learn this, what kind of ESD surgery will you be afraid of in the future? No matter how big the wound is, it doesn't matter at all!

In addition, the area where gastroenterology needs to stop bleeding is not limited to ESD surgery.

At this moment, when everyone looked at Tao Le again, they felt completely different from before.

The child will resume classes next Monday, and he will go to school to do nucleic acid this morning, and the second day at noon may be slightly delayed. Well, in fact, the second shift a few days ago was later, and I would like to invite you to Haihan.
