If there is a technology that can reduce the damage to patients, perhaps early cancers and precancerous lesions can be contained and no longer progress.
As a doctor, this is also Director Wei's dream.
"Xiaocao, listen carefully." Director Wei said quietly but seriously.
Quan Xiaocao nodded vigorously.
For Director Wei, Quan Xiaocao is as insignificant as her name. But in a sense, she represents the future!
Special equipment fixed the intestines of the general teacher. Zheng Ren felt that Su Yun was really a genius.
This equipment is really suitable for demonstrations. Although the remaining colon is only 20 centimeters, it does not affect the colonoscopy operation and the demonstration of ESD technology at all.
He didn't come this time. The patient didn't know whether he had been diagnosed with thymoma or whether he had undergone surgery. As for whether the operation would be successful, Zheng Ren didn't think about it.
The rising star of cardiothoracic surgery in the Imperial Capital cannot even treat Taiwanese thymoma. That’s a joke.
Zheng Ren thought about the misdiagnosed surgery that he had prevented, and took a deep breath.
He exhaled the stale air, put on the microscope, and took out a new pair of sterile gloves to put on.
"microscope?"
"Yes, I saw a teacher who did microsurgery when I was an intern."
"Isn't it endoscopic mucosal dissection? Why do you need a microscope?"
When the students saw Zheng Ren put on the equipment, those who knew him began to show off their knowledge, and there was a lot of discussion.
Principal Zhang turned sideways, approached Vice President Yuan, and asked: "Old Yuan, what does Dr. Zheng want to do with the microscope?"
Vice President Yuan didn't know either, but someone around him knew.
"Director Luo, why does Dr. Zheng wear a microscope?" Vice President Yuan asked.
"That's it. Boss Zheng performed an ESD operation two days ago and peeled off a precancerous lesion that invaded the muscle layer. Normally, the current ESD technology cannot remove the diseased tissue that invaded the muscle layer, but Boss Zheng used We can do it with a microscope and a colonoscope." Director Luo looked forward, looked straight at Zheng Ren, and explained to the dean.
"Surgery is contraindicated?" Vice President Yuan was also a little surprised.
"It's a taboo for surgery under the current technology. Boss Zheng has used technology to overcome this difficulty." Director Luo saw that Zheng Ren was ready, and hurriedly defended, then stopped talking, and looked at Zheng Ren intently. operation.
At this moment, Vice President Yuan was disliked.
As Zheng Ren completed his preparations, there were huge changes on the big screens on both sides.
The image that appeared on the screen was the screen of the endoscopic lens and the figure of Zheng Ren wearing white clothes and holding a colonoscope.
The two merge into one, extremely natural and not artificial at all.
"The colon is divided into four anatomical structures: mucosa, submucosal layer, muscular layer, and adventitia. We just talked about this." Zheng Ren's voice echoed in the 2nd class as more and more students poured in.
The aisles on both sides were already filled with people.
The first group of people who arrived were extremely lucky, at least they had a better position.
Because of Su Yun's careful design, there is no blind spot in 2nd Teaching, and you can see the most detailed operations on the projection screen from every corner.
This technology has only been used clinically for a few years, and anyone who can peel off the gastric wall mucosa is considered a master.
Using a colonoscope to remove appendicitis is an extraordinary move.
Not to mention the students of Imperial Medical University, even the chief directors of 912, Director Wei and Director Luo, did not know much about ESD surgery.
What the students saw was the excitement, while Director Luo and Director Wei saw the secrets.
Professor Stephen Jones remained silent and watched Zheng Ren's movements quietly.
"Xiaocao, did you see the anatomical structure clearly just now?" Director Wei asked.
"See clearly!" Quan Xiaocao said excitedly: "Boss Zheng's dissection is very detailed. It's hard to understand even if you don't understand."
Director Wei shook his head. It seemed that Quan Xiaocao was really excited. Normally she would just lower her head and talk to cover up her shyness.
At this time, Zheng Ren had already started operating, and Director Wei did not continue talking, but watched intently.
operate…
Once you get started, it's micromanipulation, which is Director Wei's technical blind spot.
Gastrointestinal surgery does not require a microscope at all.
It wasn't used before, it won't be used now, and in the future... Director Wei looked at Zheng Ren's operation and sighed inwardly.
In the future, it’s hard to say.
The forceps in front of the lens bluntly separate the colon mucosa, and then separate the mucosa bit by bit.
The field of view was Zheng Ren's microscopic field of view. The students who had only had a broad concept of the colon mucosa before but no actual impressions were filled with exclamations one after another in the 2nd class.
At the same time, in the bodies of Director Luo and Director Wei, the hormone levels rose, fell, and then rose again like the second teacher's exclamation.
The students saw the excitement, but the two directors of the 912 Gastrointestinal Surgery Department saw the real deal.
The technique of blunt separation is extremely delicate, fast and gentle, and the mucosa and submucosa are quickly separated from the muscular layer.
This gross specimen is normal human tissue with no pathological changes.
But the two directors knew that with such delicate separation, precancerous lesions and the like could not stop Boss Zheng's methods.
If the tumor is any larger, it is beyond the scope of ESD surgery and can be surgically removed.
That's another concept.
"Director Luo, can you use a microscope?" Director Wei sighed and asked Director Luo next to him.
"No." Director Luo was a little depressed. Even the serious ESD surgery to peel off the gastric mucosa could not be considered perfect, let alone the more advanced surgical technique of mucosal peeling under a microscope.
Director Wei was relieved and smiled slightly.
Director Luo felt something strange. He stared at the screen and watched Zheng Ren peel off the colon mucosa and submucosal tissue. The forceps moved between the muscle layer and the submucosa without damaging the muscle layer.
The technique was so wonderful that Director Luo sighed deeply.
"What do you mean?" he asked casually.
Director Wei just smiled and carefully watched Zheng Ren's operations on the large projection screen, without answering Director Luo's questions.
His hands moved gently, imitating Zheng Ren's operations. But Director Wei knew that it looked like he should be able to do it, but it only seemed like he could do it.
This is a microscopic operation, not an operation under direct vision.
If you were to wear a microscope, you would never be able to perform such skillful micro-manipulation in a small space.
He was a little worried. He was still older and his grasp of new technologies was definitely much worse than that of young people.
When we get back, we will kick Quan Xiaocao into Boss Zheng's group, Director Wei thought to himself. Or in the future, I will go out to the outpatient clinic and find some patients to perform ESD surgeries, and Quan Xiaocao will follow all surgeries.
I can’t believe that gastrointestinal surgery can’t find anyone to learn new techniques.
Even if they are raised, they have to raise a doctor who specializes in ESD surgery, otherwise gastrointestinal surgery will be as lonely as cardiac surgery in a few years.
