The preoperative case analysis was completed, visual field switched, and the live broadcast of the operation began 10 minutes later.

"Is Boss Zheng doing the surgery?" Lei Yinghua asked.

"Um."

"What kind of tricks are you going to take?"

"..." Peng Jia was stunned for a moment.

The technique... I don't know. Less than three hours since I learned the news, I was so busy that I had no time to pay attention to me.

Lei Yinghua didn't say anything, but just shook his head slightly.

It seems that the problem with Xinglin Garden lies in this. The surgeon does not know what surgery to take.

This is definitely not what a medical professional website should look like.

But is the surgery an emergency surgery?

It's impossible. If it was really an emergency surgery, PPT wouldn't be so beautiful that it wouldn't even find any problem.

It’s better to look at the surgery. According to the operator’s habit, it is very likely to use surgical procedures.

Just as she was thinking, Lei Yinghua saw something wrong with the picture.

This is... colonoscopy? esd technology?!

It's really ESD technology!

The esd technology, also known as endoscopic mucosal dissection, refers to a minimally invasive technique that completely removes the lesion mucosa from the submucosal layer under the endoscopic.

It was first created and applied to clinical practice in Japan in the late 1990s. The main purpose of this procedure is to diagnose and treat early gastrointestinal tumors, and has the advantage of being completely resected at one time.

But the technical requirements are high and the difficulty is high.

Lei Yinghua repeatedly summarized his experience and finally determined that using ESD technology to treat MW syndrome is the best method.

But there are also problems - the patient has so many polyps in the colorectal cavity, and some polyps are still very large. During the peeling process, intestinal perforation will occur if the patient is accidentally exposed.

In the preoperative case discussion, Lei Yinghua also saw the patient's film.

There are at least dozens of large polyps.

Do all these polyps need to be removed at one time? It should be done in two or three times.

If you have surgery yourself, you will choose this method.

The patient has little damage and there is no big risk. As for the slower speed, it is even more difficult to do.

But if the surgery is live, half of it is done and half is left, no matter how you think about it, what is wrong.

The visual field operator looked directly at the field of view of the colonoscopy screen. The colonoscopy has already gone in and is operating.

Lei Yinghua held his breath and looked carefully.

The first polyp is 6cm from the rectum to the anus. The diameter is about 1cm, and the surface is a bit unsmooth.

An experienced doctor can tell at a glance that it is likely that this polyp is in the precancerous lesion stage. That is to say, it has not been transformed into a malignant tumor, but if it is not removed, it may cause fundamental changes in a few months.

Spray the dye from the spray tube, which looks like it should be 0.5% methylene blue solution. Lei Yinghua doesn’t like to use methylene blue, and usually uses 0.4% indigo carmine.

However, this is determined based on personal preferences, and no one is right or wrong.

The methylene blue spray was very evenly, and the assistant of the surgeon was particularly good. Lei Yinghua was a little envious.

It seems to be just a small operation, but as a craftsman, this is the first difficulty.

The purpose of spraying dye is to clearly show the size of the lesion and the extent of the lesion.

Uneven spraying will invisibly increase the difficulty of the operation.

The craftsman team is very strong, and the assistant operation is almost perfect. Just a simple little detail at the beginning, Lei Yinghua made his own judgment.

The sprayed methylene blue seemed to have fallen completely before it seemed that the surgeon began to inject submucosal.

Without repeated several times, the operator will have a bulge in the part where the polyps should be separated so that there will be sufficient field of vision when separating the submucosal layer and the propria layer.

The injection contains hemostatic drugs, which can ensure that some small capillaries rupture and not produce too much blood.

After the submucosal injection is completed, electrocoagulation marks, and the endoscopic incision begins to drop the knife 5mm at the edge of the lesion.

This is too fast. What's the use of a savage player just to speed his hand? Lei Yinghua was a little disdainful.

It’s just that the surgery is done quickly, which is a sensationalist.

Endoscopic surgery was performed by doctors in the laminoscopic chamber and gastroenterology department at the beginning.

Because I am not a surgeon, the exploration process is very long.

After all, they cannot touch the anatomy of the intestines, and there are some subtleties that are difficult to deal with.

At the beginning... and now, surgeons are still used to surgery to solve problems.

However, under the general trend of minimally invasive surgery, surgeons have gradually begun to undergo ESD surgery.

Lei Yinghua is one of them and is also the best. He has a deep understanding of ESD surgery and even has his own unique insights.

The surgeon is a young challenger, but the surgery is useless to do it quickly.

Endoscopic surgery is most afraid of bleeding. Once blood vessels rupture and bleeding, it will take a very long time to deal with it.

The patient's injury is also extremely huge.

This is something that young people don’t understand, Lei Yinghua looked at it calmly.

Sure enough, according to Director Lei's idea, after the incision, the operation speed suddenly slowed down. Not only did it slow down, but the technique was also a bit clumsy.

Lei Yinghua smiled. The craftsman was still a hand-made person, not as good as he did.

The mucosa layer of the colorectal is relatively thin, and the electrocoagulation power cannot be particularly large to avoid damage to the muscle layer. The operator's choice is correct, and his electrocoagulation power is just right, and Lei Yinghua is not surprised.

If you can't grasp this detail, you dare to do a live broadcast of surgery? That's just a joke.

After the mucosa is lifted under the mucosa, use an endoscopic incision to cut the mucosa at the outer edge of the marking point.

Lei Yinghua held his breath and successfully pre-inserted the surrounding mucosa is the key to the successful ESD treatment.

The endoscopic incision was smoothly incised with the surrounding mucosa, and entered the submucosa layer through the pre-cut incision, and then annular incision was performed along the outside of the methylene blue mark.

The technique is very skillful, not like a newcomer to the ESD surgery I just explored.

This sense of proficiency is completely different from my previous judgment of the artist.... What's going on? Is it because of the sake of showing off my skills, and there are more invalid operations?

Well, it is possible. Young people always show off their hearts.

But looking at the operation process, Lei Yingjie even had an illusion that the surgeon had performed ESD surgery and had at least 800 units before he could have such a skilled feel.

Has anyone had so many ESD surgeries in China?

No, there is no need to recall this, Lei Yingjie can be sure of it. Because he thought about it, he couldn't do it.

After cutting, the separator was sent in.

Blunt separation, this is the most important node.

Many laparoscopy doctors and gastroenterology doctors have always been unable to do well in this regard, while general foreign doctors are much better.

After all, surgical cutting causes many times to free the intestine, and surgeons are very familiar with the intestine.

The separator is not separated quickly, but it is not slow either. It is layer by layer, just like a cook. Each layer has a clear anatomical structure, avoiding some small blood vessels, and using electric burning, electrocoagulation can stop bleeding at any time.

After 1′22″, a piece of polyp was cut off.

At this speed... Lei Yinghua nodded slightly. The surgeon dared to perform live surgery, but his level was still good.

The entire process of the outermost rectal polyps is like a classic textbook.

Although there is no textbook for ESD surgery so far, Lei Yinghua imagined that the operation he just saw was perfect. If you have to find fault, you can only say that the speed in the later stage is a little slower and some invalid operations are still available.

What young people have done to show off their skills and have more operations out of thin air. But this age is not good.
