Chapter 1539

If there is a technology that can reduce the damage of patients, perhaps early cancer and precancerous lesions can be stopped and no progress can be made.

As a doctor, this is also director Wei's dream.

"Xiaocao, listen." Director Wei said quietly but seriously.

Quan Xiaocao nodded hard.

For Director Wei, Quan Xiaocao is just like her name, insignificant. But in a sense, she represents the future!

Specific equipment fixed the teacher's intestines. Zheng Ren thought Su Yun was a genius.

This set of equipment is really suitable for demonstration. Although the remaining colon is only 20 cm, it does not affect colonoscopy operation and ESD technology.

He didn't come this time. The patient didn't know whether there was a definite diagnosis of thymoma and whether there was an operation. As for whether the operation will succeed, Zheng Ren didn't think.

The future star of imperial cardiothoracic surgery can't even make a thymoma. That's a joke.

Zheng rennaohai thought about the misdiagnosed operation that he had stopped and took a deep breath.

Spit out the turbid gas, put on the microscope, and put on a new pair of sterile gloves.

"Microscope?"

"Yes, I saw a teacher do microsurgery during my internship."

"Isn't it endoscopic mucosal dissection? Why wear a microscope?"

When the students saw Zheng Ren put on his equipment, those who knew him began to show their knowledge and talk about it.

President Zhang leaned close to Vice President yuan and asked, "old yuan, what does Dr. Zheng want to do with a microscope?"

Vice President yuan doesn't know, but someone around him knows.

"Director Luo, why does Dr. Zheng wear a microscope?" Vice President yuan asked.

"Well, two days ago, boss Zheng had an ESD operation to peel off a precancerous lesion invading the muscle layer. Normally, the current ESD technology can't remove the diseased tissue invading the muscle layer, but boss Zheng did it with a microscope and enteroscopy." Director Luo looked straight ahead at Zheng Ren and explained to the dean.

"Surgical contraindications?" Vice President yuan was also surprised.

"It is a surgical taboo under the existing technology. Boss Zheng has overcome this difficulty with technology." Director Luo looked at Zheng Ren's preparation and hurriedly apologized. He stopped talking, but stared at Zheng Ren's operation.

At this moment, vice president yuan was despised.

With Zheng Ren's preparation, great changes have taken place on the big screens on both sides.

The image on the screen is the screen of endoscope and the figure of Zheng Ren wearing white clothes and holding enteroscope.

The combination of the two is very natural and not artificial at all.

"The colon is divided into four anatomical structures: mucosa, submucosa, muscularis and adventitia. We just talked about this." Zheng Ren's voice echoed in the 2 teaching. At this time, more and more students poured in.

The aisles on both sides are full of people.

The first group of people were very lucky to have at least a better position.

Because of Su Yun's mental design, there is no blind spot in 2 teaching, and the most detailed operation can be seen on the projection screen in every corner.

This technology has just been carried out in clinic for a few years, and those who can peel off the gastric mucosa are big hands.

Cutting appendicitis with enteroscope is a move of flying fairy outside the sky.

Not to mention the students of imperial Medical University, even the directors of 912, Director Wei and director Luo, don't know much about ESD surgery.

The students watched the excitement, while director Luo and Director Wei watched the doorway.

Professor Stephen Jones kept silent and quietly watched Zheng Ren's actions.

"Xiaocao, did you see the anatomical structure just now?" Director Wei asked.

"See clearly!" Quan Xiaocao said excitedly, "boss Zheng dissects very carefully. It's difficult to understand."

Director Wei shook his head. It seems that Quan Xiaocao is really excited. Usually she only talks with her head down to hide her shyness.

At this time, Zheng Ren had already started the operation, and Director Wei did not continue to say, but looked at it wholeheartedly.

Operation

The first step is micromanipulation, which is the technical blind spot of director Wei.

Gastrointestinal surgery doesn't use a microscope at all.

Not used before, not now, not in the future... Director Wei sighed at Zheng Ren's operation.

In the future, it's hard to say.

The pliers in front of the lens passively separated the colonic mucosa, and then separated the mucosa a little bit.

The visual field is Zheng Ren's microscopic visual field. The students who had only a broad concept of colonic mucosa but had no actual impression sounded one after another in teaching 2.

At the same time, in the bodies of director Luo and Director Wei, hormone levels rise, fall and rise again like the scream of two teachers.

The students watched the excitement, but the two directors of 912 gastrointestinal surgery looked at the real doorway.

The technique of blunt separation is extremely delicate, with high speed, gentle manipulation, and rapid separation of mucosa and submucosa from the muscular layer.

This gross specimen is normal human tissue without lesions.

But the two directors knew that to this extent, precancerous lesions and the like could not stop boss Zheng's technique.

If the tumor is larger, it will be beyond the scope of ESD operation and can be surgically removed.

That's another concept.

"Director Luo, can you use a microscope?" With emotion, Director Wei asked director Luo around him.

"No." Director Luo is a little depressed. What he has done is not perfect, let alone the more advanced surgical method of mucosal stripping under the microscope.

Director Wei was relieved and smiled.

Director Luo felt something strange. He stared at the screen and watched Zheng Ren peel off the colonic mucosa and submucosal tissue. The pliers swam between the muscular layer and the submucosal layer without damaging the muscular layer.

The technique was so wonderful that director Luo sighed.

"What do you mean?" He asked casually.

Director Wei just smiled and looked seriously at Zheng Ren's operation on the large projection screen. He didn't answer director Luo's questions.

His hand moved gently to simulate Zheng Ren's operation. But director Wei knows that it looks like he should be able to do it, but it just looks like it.

This is a micromanipulation, not an operation with the naked eye.

If you wear a microscope, you will never be able to do such skilled micromanipulation in a narrow space.

He is a little sad. He is still old and his mastery of new technology must be much worse than that of young people.

Go back and drive Quan Xiaocao to boss Zheng's group. Director Wei thought to himself. Or go out of the clinic and find some patients for ESD surgery. All the operations let Quan Xiaocao follow.

I don't believe gastrointestinal surgery can't find a person to learn new technology.

Even if it is raised, you have to raise a doctor who specializes in ESD surgery. Otherwise, gastrointestinal surgery will be as lonely as cardiac surgery in a few years.
