"esd technique?"

The Japanese doctors I was facing looked at me and I looked at you, with a blank look in their eyes. Apparently no one had heard of this term.

When Lan Lijuan heard this, she thought that it was indeed the case. Now that it was time for classmate Chen Qi to show off and get slapped in the face, she knew that he was not willing to suffer any loss.

The students in the master's degree class in endoscopy also suddenly became energetic and wanted to hear how their instructors defeated foreign doctors and brought glory to the country.

Sakutaji asked a little strangely: "Excuse me, Doctor Chen, what is ESD surgery?"

Chen Qi smiled lightly and said to the Japanese doctor 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:

"The EMR procedure you invented is actually an improvement on the gastroscopic biopsy technology, right?"

"Yes!"

"The specific method of the EMR surgery you introduced is to pump physiological saline into the mucosal layer, then make polyps, early cancers, etc. protrude, then use surgical thread to ligate, or negative pressure suction to suck up the diseased tissue, and finally use electricity

A knife can remove the lesion, right?"

Japanese doctors all nodded their heads.

There are some principles that you can't even think of until you explain them. Once you explain them, that's all. It depends on whether you have thought of them.

At least so far, the EMR technique originated by the University of Tokyo is very successful, 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, etc.

Chen Qi continued talking to the pictures on the slide:

"With all due respect, this surgery has a very big disadvantage, that is, it is difficult to bandage some flat lesions completely. Like this, even after injecting saline, the lesion is still not raised, and you can't bandage it. How to cut it?"

If the suction method is used, due to the limitation of the size of the transparent cap, the size of the lesion that can be resected is still limited, and it is difficult to suck the lesion into the transparent cap with negative pressure to completely lift it up, which will also cause risks such as incomplete resection and local recurrence.<

/p>

Therefore, EMR surgery should only be used for cases such as some early-stage cancers that must be limited to the mucosa, have no metastasis, and are within 2cm in size, and can be resected en bloc, right?"

Chen Qi asked these rhetorical questions, and the Japanese doctor immediately understood.

The Chinese doctor in front of me didn’t know anything about endoscopy, on the contrary, he was very proficient, so everyone started to look serious.

The Japanese doctors present here have a bad premonition, and at the same time they are very curious about what shocking words this Dr. Chen from China has to say, or is he just trying to scare people?

Chen Qi pointed at the anatomical structure diagram of the stomach and said.

"The full name of the ESD surgery I am talking about is endoscopic submucosal dissection, which when translated is called endoscopic submucosal dissection."

At this time, a Japanese doctor asked in a low voice: "Excision? Peeling? What's the difference between the two?"

Chen Qi chuckled lightly, and his crooked mouth also showed a bit of impoliteness.

"The difference between the two is huge. EMR can be simply understood as the removal of the mucosal layer, while ESD involves repeated submucosal injection of epinephrine saline to separate the mucosal layer, submucosa and lower mucosa at the lesion.

The muscle layer is completely separated.

Therefore, ESD has a wider range of resection than EMR, and the depth of resection is deeper. The range can exceed two centimeters, and the depth can reach the submucosal layer. Thus, the lesion can be removed in large pieces and completely."

Boom, the Japanese doctors across the street started talking about it.

Everyone present was a gastroenterologist who also performed EMR surgery, so when Chen Qi mentioned ESD surgery, they immediately thought of the tips and principles.

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 just knew that in 1989, even Japan had only mastered the EMr technique, so he had an idea and showed off this new technique that was originally only invented in 1995.

Historically, ESD surgery was invented by Professor Gotota, a Japanese doctor at the University of Tokyo Medical Center.

When Chen Qi realized that ESD had not been invented by them, he decisively cut off his beard. This would not only slap them in the face, but also make him an original artist. How cool it was.

The Japanese doctor opposite had been discussing for a long time, and the argument became more and more fierce. It was obvious that some people were very unconvinced:

"No, I think this so-called esd technique is a complete plagiarism of our emr technique."

"I think so too. You see, the basic principles are the same. They all need to inject saline and adrenal saline to separate the mucosa."

"Director Saku, we cannot give up Japan's precious endoscopic results."

"Let me ask you first, what exactly is this ESD surgery? What if you are bragging? After all, no one has ever seen this kind of surgery."

Japanese doctors are all talking about it, and everyone has the same view, that is, their own intellectual property rights cannot be plagiarized by foreigners.

Department Director Sakuta Tsukasa also felt that the two surgeries were very similar, so he decided to ask for more information.

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

"Chen Sang, my colleagues and I are very interested in the ESD technique you mentioned. Now I have two questions. One is whether the ESD technique you mentioned is an improvement on our EMR technique? Secondly,

How many successful cases are there of the ESD surgery you mentioned?"

The Japanese still don’t want to give up.

An idea flashed through Chen Qi's mind.

It is undeniable that the ESD technique is indeed an improvement on the EMR technique. Even the tunnel drilling method POEM technique that Chen Qi previously developed was also developed on the basis of ESD.

But can Chen Qi say that?

You say that your EMR surgery is the ancestor of endoscopic surgery and the basis for subsequent surgeries?

If he said that, the little devils would definitely catch him and shout all over the world that Chen Qi is a plagiarist and not the original author.

So I can’t even admit it even to death, I’ll just quibble to the end.

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

.

As for the similarities between EMR surgery and ESD surgery, I can only say that this is a coincidence, but what I also want to say is that ESD surgery has wider clinical applications, better curative effect, and cleaner resection.

, so it is a more advanced technique than emr technique."

"Baga!"

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

Chen Qi didn't know much Japanese, but he still understood these two words. Not only Chen Qi understood it, but also the 19 Chinese doctors and students around him understood it, and everyone's faces suddenly became serious.<

/p>

Chen Qi chuckled:

"Why Baga? What is the reason for your anger? This is the fact. Our country in China not only invented the ESD technique, but also invented the POEM technique. I am not bragging, but there are witnesses.

WGO, Professor Grace, President of the World Society of Gastroenterology, and Professor Bradrick from Sid Sinai Medical Center in the United States also fully affirmed the advancement of ESD surgery. In January, they came to China to see me in person.

These operations."

If there were people who were dissatisfied before, now Chen Qi brought out the Japanese American father, which made the Japanese doctors look at each other.

Have Americans certified it?

How come they haven’t heard anything about it? Nor have they seen any relevant papers published?

As an equipment dealer, Futama Kaito had much better information and immediately stood up:

"Everyone, Professor Grace will indeed visit China in January, and as far as I know, Dr. Chen should have performed a remarkable operation and solved a difficult problem for a wealthy American."
p>

Seeing that the Japanese doctor was still a little unconvinced, Ercun Haidou pretended to be kind and suggested:

"Dr. Chen, there is an old saying in China that the eyes are the truth and the ears are the eyes. I wonder if you can perform a few professor's surgeries and demonstrate to everyone what the ESD surgery is and what the POEM surgery is?"<

/p>

This is the purpose of Kaito Futura.

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

There are more than a dozen endoscopic instrument manufacturers in the world, such as Olympus, KARL STORZ, Fujifilm, Pentax, Stryker, etc., all of which are strong competitors.

Nipro Company has strong comprehensive strength, but it does not have many advantages in the field of endoscopy.

So how to find spokespersons, especially technical masters who can lead new surgical techniques, and let them use Nipro's endoscopes to serve as an advertising function? This is an issue that company executives attach great importance to.

Take Chen Qi in front of you, for example. He had a great influence in plastic surgery and hand surgery.

For every operation, whether clinical or teaching, Chen Qi only uses Nipro products. This makes Nipro's brand trusted by other plastic surgeons and hand surgeons, and sales are rising steadily.<

/p>

Now I heard that Chen Qi is planning to engage in endoscopic surgery. It just so happens that Nipro Company also wants to promote its own endoscopes, so Chen Qi is one of the best spokespersons they think.

However, Chen Qi has not performed a public teaching operation internationally. No one has seen the level of endoscopic surgery except those American doctors.

What to do?

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