If there was a technique that could reduce the patient's damage, perhaps early-stage cancer and precancerous lesions could be contained and would not progress.
As a doctor, this was also Chief Wei's dream.
"Xiaocao, listen carefully," Chief Wei said in a low but serious voice.
Quan Xiaocao nodded vigorously.
To Chief Wei, Quan Xiaocao was like her name, insignificant. But in a sense, she represented the future!
Special equipment was used to fix the intestines of the cadavers. Zheng Ren felt that Su Yun was really a genius.
This set of equipment was really suitable for demonstrations. Although the remaining colon was only 20 centimeters, it did not affect the endoscope operation and the demonstration of ESD technology at all.
This time, he did not come. He did not know if the patient had been diagnosed with a thymoma or if he had undergone surgery. As for whether the surgery would be successful or not, Zheng Ren did not think about it.
It would be a joke if the rising star of the Imperial Capital's cardiothoracic surgery could not even handle a thymoma.
Zheng Ren thought about the misdiagnosis surgery that he had stopped and took a deep breath.
He exhaled, put on the microscope, and took a new pair of sterile gloves.
"A microscope?"
"Yes, I saw a teacher perform microsurgery when I was an intern."
"Isn't it an endoscopic mucosal dissection? Why is he wearing a microscope? "
When the students saw Zheng Ren put on the equipment, those who knew him began to show off their knowledge and discuss spiritedly.
Principal Zhang turned sideways and approached Deputy Director Yuan. He asked, "Old Yuan, why is Doctor Zheng wearing a microscope?"
Deputy Director Yuan did not know either, but someone around him knew.
"Chief Luo, why is Doctor Zheng wearing a microscope?" Deputy Director Yuan asked.
"It's like this. Two days ago, Boss Zheng performed an ESD surgery and removed a precancerous lesion that invaded the muscle layer. Normally speaking, the current ESD technology is unable to remove the lesion tissue that invades the muscle layer, but Boss Zheng used a microscope and an endoscope to do it, "Chief Luo explained to the director as he looked straight ahead at Zheng Ren.
"Surgical contraindications?" Deputy Director Yuan was also a little surprised.
"It's a surgical contraindication under the current technology. Boss Zheng used technology to overcome this difficulty." Chief Luo saw that Zheng Ren was ready and hurriedly explained. He did not say anything else but stared intently at Zheng Ren's operation.
At this moment, Deputy Director Yuan was despised.
As Zheng Ren finished his preparations, there was a huge change on the big screens on both sides.
The image that appeared on the screen was of a laparoscope and Zheng Ren's figure in a white coat, holding an endoscope.
The combination of the two was incomparably natural and not the slightest bit artificial.
"The colon is divided into four anatomical structures: mucosa, submucosa, muscularis, and adventitia. We've just talked about this. "Zheng Ren's voice echoed in the secondary school. At this time, more and more students were pouring in.
The aisles on both sides were already filled with people.
The first batch of people who arrived were incomparably fortunate. At least they had a slightly better position.
Because of Su Yun's meticulous design, there were no blind spots in the second school. The most detailed operations could be seen on the projection screen in every corner.
This technique had only been developed in the clinic for a few years, and those who could peel off the gastric mucosa were considered experts.
Using a colonoscope to remove appendicitis was even more of a miracle.
Not to mention the students of the Imperial Capital Medical University, even the chief physicians of the Imperial Capital Medical University, Chief Wei and Chief Luo did not know much about ESD surgery.
The students were here to watch the show, but Chief Luo and Chief Wei were here to watch the process.
Professor Stephen Jones did not say a word and quietly watched Zheng Ren's movements.
"Xiaocao, did you see the anatomical structure just now clearly?" Chief Wei asked.
"I saw it clearly!" Quan Xiaocao said excitedly. "Boss Zheng's dissection is very detailed. It's hard not to understand."
Chief Wei shook his head. It seemed that Quan Xiaocao was really excited. Usually, she would only lower her head and speak to hide her shyness.
At this moment, Zheng Ren had already started the operation. Chief Wei did not continue speaking but focused on watching.
Operation …
The moment he started, it was a microscopic operation. It was Chief Wei's technical blind spot.
In the gastrointestinal surgery department, there was no need for a microscope.
It was not used in the past, not now, but in the future … Chief Wei looked at Zheng Ren's operation and sighed in his heart.
In the future, it was hard to say.
The forceps in front of the camera bluntly separated the colon mucosa, and then separated the mucosa bit by bit.
The field of view was Zheng Ren's microscopic vision. Previously, the students only had a broad concept of the colon mucosa, but they did not have a real impression of it. Cries of surprise rang out one after another in the secondary school.
At the same time, in Chief Luo and Chief Wei's bodies, the hormone levels rose, fell, and rose again like the exclamations of the secondary school.
The students were watching for fun, but the two chief physicians of the 912 Department of Internal Gastrointestinal Surgery were watching the real way.
The blunt dissection technique was extremely exquisite. It was very fast and gentle. The mucosa and submucosa were quickly separated from the muscular layer.
This section of the specimen was normal human tissue. There were no lesions.
However, the two chief physicians knew that with such exquisite separation, precancerous lesions and the like could not stop Boss Zheng's technique at all.
If it was a larger tumor, it would exceed the scope of ESD surgery and could be surgically removed.
That was another concept.
"Chief Luo, do you know how to use a microscope?" Chief Wei sighed and asked Chief Luo beside him.
"I don't." Chief Luo was a little depressed. He could not even do a proper ESD surgery to remove the gastric mucosa perfectly, let alone a more advanced surgical method to remove the mucosa under the microscope.
Chief Wei was relieved and smiled slightly.
Chief Luo felt a little strange. His eyes were fixed on the screen as he watched Zheng Ren peel off the colon mucosa and submucosa tissue. The forceps swam between the muscular layer and the submucosa, not hurting the muscular layer.
Chief Luo was moved by the ingenuity of the technique.
"What do you mean?" he asked casually.
Chief Wei only smiled and looked seriously at Zheng Ren's operation on the big screen. He did not answer Chief Luo's question.
His hand moved gently, simulating Zheng Ren's operation. However, Chief Wei knew that he should be able to do it on the surface, but it was just on the surface.
This was a microscopic operation, not an operation under direct observation with the naked eye.
If he wore a microscope, he would definitely not be able to perform such a skilled micro-operation in a narrow space.
He was a little worried. He was still old, and his grasp of new techniques was definitely much worse than that of young people.
When he went back, he would kick Quan Xiaocao into Boss Zheng's group, Chief Wei thought to himself. Or in the future, when he went out to the clinic, he would also find a group of patients to perform ESD surgery and let Quan Xiaocao follow him for all the surgeries.
He did not believe that the gastrointestinal surgery department would not be able to find someone to learn new techniques.
Even if he were to raise them, he would have to raise a big shot who specialized in ESD surgery. Otherwise, in a few years, the gastrointestinal surgery department would be as lonely as the cardiac surgery department.
