"ESD?"

Facing the doctor Benben, you look at me, I look at you, there is a blank in his eyes, obviously everyone has never heard of this term.

When Lan Lijuan heard this, she thought that this was the case, and now that it was time for Chen Qi to pretend to be forced to slap her face, she knew that he was unwilling to suffer a little loss.

The students of the master's class in endoscopy also came to the spirit at once, and wanted to hear how their mentors PK foreign doctors and won glory for the country.

Tsukasa Sakuda asked a little strangely, "May I ask Dr. Chen, what is ESD?" ”

Chen Qi chuckled lightly and said to Dr. Yuben, who was making a report:

"Please move the previous slide to page 19, yes, that's it, thank you."

After Chen Qi finished speaking, he stood up, walked to the front of the screen, and explained to the slide picture:

"Your invention of EMR is actually an improvement on the basis of gastroscopic biopsy technology, right?"

"Yes!"

"Your introduction to this EMR surgery, the specific method is to inject normal saline into the mucosal layer, and then let any polyps, early cancer protrude, and then use the surgical line to ligate, or negative pressure suction to suck up the diseased tissue, and finally remove the lesion with an electric knife, right?"

Dr. Ben nodded his head again and again.

There are some principles, you can't think of it if you don't say it, you can't think of it, and if you say it's broken, it's like that, it depends on whether you think of it.

At least so far, the EMR procedure, which was originally developed by the University of Tokyo, has been very successful and has been recognized by the international mainstream medical community, and is widely used in the treatment of superficial lesions of the digestive tract.

For example, gastrointestinal polyps, submucosal tumors, precancerous lesions, and so on.

Chen Qi continued to look at the pictures on the slide:

"With all due respect, this operation has a very big disadvantage, that is, it is difficult to completely tie some flat lesions, like this, after injecting saline, the lesion still does not bulge, and you can't cover it, how to cut it?

If the suction method is used, the size of the lesion that can be removed is still limited due to the size limitation of the transparent cap, and it is difficult for the negative pressure to inhale the lesion into the transparent cap and lift it completely, which also causes the risk of incomplete resection and local recurrence.

Therefore, EMR should only be used for some early-stage cancers, for example, and must be confined to the mucosa, without metastasis, and within 2cm in size, and can be removed in one piece, right? ”

Chen Qi asked these rhetorical questions, and Dr. Ben immediately understood.

The Huaguo doctor in front of him did not understand endoscopy, on the contrary, he was very proficient, so everyone's expressions began to become serious.

The doctors present had a bad premonition, and at the same time, they were very curious about what this Dr. Chen from Hua Guo had to say, or was it just to scare people?

Chen Qi pointed to the anatomy diagram of the stomach at this time.

"And what I call ESD is endoscopic submucosal dissection, which translates to endoscopic submucosal dissection."

At this time, a doctor was asking in a low voice, "Excision?" Stripping? Is there any difference between the two? ”

Chen Qi chuckled, and the crooked look of his mouth was also a little impolite.

EMR can be simply understood as the removal of the mucosal layer, while ESD is through repeated submucosal injection of epinephrine saline and separation, completely separating the mucosal layer at the lesion and the muscular muscularis at the lower level.

Therefore, ESD is more extensive than EMR excision, and the depth of excision is deeper, the range can be more than two centimeters, and the depth can reach the submucosa. As a result, the lesion is removed in large and complete pieces. ”

Boom, the doctors on the other side of the world all started talking.

The gastroenterologists present also do EMR, so when Chen Qi mentioned ESD surgery, they immediately thought of the trick and principle.

Zhang Weizhong also quietly came over:

"Dean Chen, why haven't I heard you mention this ESD technique?"

Chen Qi thought to himself that I had only learned that in 1989, he had only done EMR, so he had an idea to take out this new technique, which was originally to be invented in 1995, to show off.

Historically, ESD was invented by Dr. Gotoda of the University of Tokyo Medical Center.

When Chen Qi realized that ESD had not yet been invented by them, he decisively cut off his beard, which could not only slap them in the face, but also become an original magician, how cool it was.

On the other side, Dr. Ben discussed for a long time, and the argument became more and more fierce, and obviously some people were very unconvinced:

"No, I think this so-called ESD technique is completely plagiarized from our EMR technique."

"I think so, you see, the basic principle is the same, you need to inject saline and adrenal saline to separate the mucosa."

"Director Saku, we can't give away the precious results of endoscopy."

"First of all, let's ask, what is this ESD surgery all about? What if people are bragging? After all, no one has ever seen this kind of surgery. ”

The doctors are all talking, and everyone agrees that their intellectual property cannot be plagiarized by foreigners.

The head of the department, Tsukasa Sakuda, also felt that the two surgeries were very similar, so he decided to ask about it.

I saw him stand up and bow slightly to Chen Qi:

"Chen Sang, my colleagues and I are very interested in what you said about ESD, and now I have two questions, one is that the ESD you are talking about, is it an improvement on our EMR? Second, how many successful cases of ESD are you talking about? ”

said that I still don't give up.

Such a thought flashed through Chen Qi's heart.

It is undeniable that ESD is indeed an improvement on EMR, and even the tunnel punching method POEM made by Chen Qi before was developed on the basis of ESD.

Can Chen Qi say that?

Say that your EMR is the ancestor of endoscopy and the basis of subsequent surgeries?

If he said so, the little devil would definitely catch it, and then shout all over the world that Chen Qi was a plagiarist, not an original.

Therefore, you can't admit it even if you kill you, and you can argue to the end.

"I can answer these two questions, first, to be honest, I didn't know that you had developed EMR before I came to the University of Tokyo Medical Center, and today is the first time I have heard about it, so I can assure you of that.

As for the many similarities between EMR and ESD, I can only say that this is a coincidence, but I would also like to say that ESD is more advanced than EMR because it is more widely used in clinical practice, has better efficacy, and is cleaner in excision. ”

"Yaga!"

Someone on the other side cursed lightly, but it was especially noticeable in the silent conference room.

Chen Qi didn't know much Japanese, but he still understood these two words, not only Chen Qi understood, but even the 19 Chinese doctors and students around him understood all of them, so everyone's faces suddenly fell.

Chen Qi chuckled:

"Why Yaga? What is the reason for your annoyance? In fact, we in China not only invented ESD, but also invented POEM, which is not my bragging, but there are witnesses.

WGO, Professor Grace, President of the World Society of Gastroenterology, and Professor Bradrick of the Sidsinai Medical Center in the United States also fully affirmed the advancement of ESD surgery. In January, they came to China to see me perform these surgeries. ”

If someone was dissatisfied before, now Chen Qi brought out his own father of the rice country, which made Dr. Yuben look at each other.

Have all the people in the United States been certified?

Why haven't they heard anything about it? Haven't seen a paper come out yet?

As an equipment merchant, Ercun Haidou is much more well-informed, and immediately stood up:

"Ladies and gentlemen, Professor Grace is indeed going to visit China in January, and as far as I know, Dr. Chen must have performed a remarkable operation to solve a difficult problem for a wealthy man in the United States."

Seeing that Dr. Yumoto was still a little unconvinced, Ercun Haidou pretended to be kind and suggested:

"Dr. Chen, there is an old saying in China, the eyes are believing, the ears are false, I wonder if you can do a few professors' surgeries and demonstrate to everyone, what is ESD surgery, and what is POEM surgery?"

This is the purpose of Futamura Kaito.

As the largest medical device manufacturer in Japan, Nipro's products are not limited to traditional surgical instruments, they are also involved in the production of endoscopic instruments.

There are more than a dozen endoscopy manufacturers in the world, such as Olympus, Carl Storz, Fujifilm, Pentax, Stryker, etc., which are strong competitors.

Nipro is a strong comprehensive company, but it does not have many advantages in the field of endoscopy.

Therefore, how to find spokespersons, especially technical masters who can lead new surgical methods, let them use the endoscopy instrument of Nipro Company, and play an advertising role, which is the issue that the senior management of the company attaches great importance to.

For example, Chen Qi in front of him, he had a great influence in plastic surgery and hand surgery.

Every time he performs an operation, whether it is a clinical operation or a teaching operation, Chen Qi only uses Nipro products, which makes Nipro's brand trusted by other plastic surgeons and hand surgeons, and sales are rising.

Now that they heard that Chen Qi was about to play endoscopic surgery, and it happened that Nipro also wanted to promote its own endoscopes, Chen Qi was one of the best spokespersons in their opinion.

However, Chen Qi has not done a public teaching operation in the world, and no one has seen the level of endoscopic surgery except for those doctors in the United States.

What to do?

The best way is to invite Chen Qi to visit and travel, and then find a way to let him take action.

In front of many peers, what is his level of endoscopic surgery?

Now Chen Qi has a small conflict with the doctors at the University of Tokyo Medical Center, which is exactly what Kaito Futamura wants.

In this way, Chen Qi operated in front of the doctors in Tokyo, and people would not be polite, they would definitely stare at him, and they would not put a little water, so that the top gastroenterologist in this book would test Chen Qi's true level.

When Chen Qi heard Futamura Kaidou's surgical suggestion, he was not disgusted in his heart.

He wants to establish an endoscopic treatment center in China and even the world, and the operating room he needs is not enough, and the endoscopic instruments he needs are not one set or two, which requires a large investment.

Man and machine are indispensable.

Especially in front of him, he has to take 15 students, but now there is only one endoscopic operating room, only one set of advanced equipment, and there are many monks and few porridges, which is obviously not enough.

The hospital has no money, what should I do? Of course, it's to pull sponsorship, and Nipro Company is the big injustice he likes.

People want him to advertise, he wants other people's sponsorship, everyone has their own ghosts, and they hit it off.

"I think Mr. Futamura's proposal is very good, and if necessary, I can do teaching surgery at any time, and I also welcome the advice of my colleagues."

When Dr. Ben heard this, he was even more excited, half angry, half unconvinced, so they all sneered.

When Futamura Kaito saw that Chen Qi agreed to make a move, he felt a sense of joy in his heart, so he looked at Professor Sakuda Tsukasa and wanted to ask him if he agreed?

Professor Sakuda Tsukasa was noncommittal, he was not young and impulsive, and what the gold lord's father meant was what he meant.

"So Chen Sang, what kind of patient do you need? We will fully cooperate. ”

Not everyone is suitable for endoscopic surgery, this must be Chen Qi to choose the patient himself, Professor Sakuda Tsukasa will not set up trouble to deliberately embarrass Chen Qi.

Chen Qi thought about it for a while, because of the limitation of endoscopic tools, there are not many types of surgeries he can do at present, so he should mainly focus on what he is good at:

"In this way, I am going to do a fundoplication, a POEM surgery, an ESD surgery, and if possible, early cancer, such as esophageal cancer, stomach cancer."

Futamura Kaito suddenly interjected:

"Dr. Chan, can we adopt an open didactic surgical model? I think the gastroenterologist at Quanben will be very interested in gastrointestinal endoscopy. ”

The businessman must hope that the more doctors who will watch this operation as many as possible, and seize every opportunity for hype, so that the brand of Nipro can be valued by more doctors.

Chen Qi is afraid of a bird, a few small endoscopic surgeries and take it down!

"Yes, it's up to you, I'll follow the arrangements of Mr. Futamura and Professor Saku."

Because it takes time to find a suitable patient, but Chen Qi can't stay in Yuben for a long time, so the four public teaching surgeries are scheduled for 3 days later.

The name and difficulty of the operation were also announced.

The news that Dr. Hua Guo was preparing to perform endoscopic teaching surgery at the University of Tokyo Medical Center immediately spread, causing a stir in the entire field of gastroenterology.

I can't help but be a sensation, there are two hype points in this.

A doctor from a poor and backward country actually went to the most developed country in the world to teach the top doctors to teach surgery?

Second, endoscopic surgery can play so many tricks? I said that I haven't developed a new technique yet, do you understand it?

Again, when elementary school students give calculus to college students, the sensational effect is not hard to imagine.

Under the sponsorship of Nipro, the University of Tokyo Medical Center and the Society of Gastroenterology organized 300 gastroenterologists from major hospitals to travel to Tokyo to observe the operation.

The news that Chen Qi was doing something in Yueben was also spread to all parts of the world.

The domestic medical community is quite worried, a Chinese doctor went to Yueben to kick the gym, it was good to win, but it was a shame for the country to lose.

Professor Grace, the president of the WGO Society in the United States, personally made a trip to the book, adding a sense of authority and tension to this teaching operation.
