Chapter 1589: 1539 Microscopic Teaching (Sect Master's Fluffing Fur Cavity Big Bird Extra Update)

If there were a technique that could reduce patients' injuries, perhaps early cancers and precancerous lesions could be contained, preventing further progression.

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

"Xiao Cao, listen carefully." Director Wei said softly but seriously.

Quan Xiaocao nodded vigorously.

To Director Wei, Quan Xiaocao was as insignificant as her name. Yet in some sense, she represented the future!

The specific equipment fixed the cadaver's intestine for the anatomy professor; Zheng Ren thought Su Yun was a genius.

This set of equipment is truly perfect for demonstration; although the remaining colon is only twenty centimeters, it does not affect colonoscope operation or the demonstration of ESD technique at all.

This time he didn't come to class; the patient didn't know whether they had been diagnosed with a thymoma or had surgery. As for whether the surgery would succeed if performed, Zheng Ren didn't think about it.

The rising star of Capital's Cardiothoracic Surgery can't even handle a thymoma from Taiwan—that would be a joke.

Zheng Ren thought of the misdiagnosis surgery he had prevented, and took a deep breath.

He exhaled the stale air, put on the microscope, and then took a new pair of sterile gloves and put them on.

"Microscope?"

"Yes, when I was an intern I saw a teacher perform microsurgery."

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

When the students saw Zheng Ren putting on the equipment, those who knew began to show off their knowledge, and discussions erupted.

President Zhang turned sideways, approached Vice President Yuan, and asked, "Old Yuan, what is Doctor Zheng intending to do by wearing the microscope?"

Vice President Yuan didn't know either, but someone nearby did.

"Director Luo, why is Doctor Zheng wearing the microscope?" Vice President Yuan asked.

"It's like this: a few days ago, Boss Zheng performed an ESD procedure, resecting a precancerous lesion that had invaded the muscular layer. Normally, current ESD technology cannot remove lesions that have invaded the muscular layer, but Boss Zheng managed to do it by using a microscope together with the colonoscope." Director Luo stared straight ahead, gazing intently at Zheng Ren, and explained to the dean.

"Surgical contraindication?" Vice President Yuan also seemed surprised.

"It's a contraindication under current technology; Boss Zheng overcame this obstacle with his technique." Director Luo, seeing that Zheng Ren had finished preparing, hastily gave a brief explanation, then fell silent and stared fixedly at Zheng Ren's operation.

At this moment, Vice President Yuan was looked down upon.

As Zheng Ren finished preparing, the large screens on both sides underwent a major change.

The image appearing on the screen was the laparoscope's display together with Zheng Ren in a white coat, holding a colonoscope.

The two merged into one, utterly natural, with no affectation.

"The colon consists of four anatomical structures: mucosa, submucosa, muscular layer, and serosa. We just covered this." Zheng Ren's voice echoed in Classroom 2, and more and more students poured in.

The aisles on both sides were already packed with people.

The earliest arrivals felt extremely fortunate, at least securing a somewhat better spot.

Because Su Yun designed it with care, Classroom 2 has no blind spots; every corner can see the most detailed operation on the projection.

This technique has only been clinically deployed for a few years; anyone able to strip the gastric mucosa is considered an expert.

Using a colonoscope to remove an appendix is even more of a heavenly feat.

Not to mention the students of Capital Medical University; even the heads of Department 912—Director Wei and Director Luo—don't know much about ESD surgery.

The students watched for the excitement, while Directors Luo and Wei watched for the technique.

Professor Steven Jones remained silent, quietly observing Zheng Ren's actions.

"Xiao Cao, did you see the anatomical structure clearly just now?" Director Wei asked.

"I saw it clearly!" Quan Xiaocao said excitedly, "Boss Zheng's dissection is so meticulous that it's hard not to understand."

Director Wei shook his head; it seemed Quan Xiaocao was truly excited, as she usually speaks with her head down to hide her shyness.

At this point, Zheng Ren had already begun the operation, so Director Wei stopped talking and focused intently on watching.

Operation……

As soon as he started, it was microscopic operation—a blind spot in Director Wei's technique.

In gastroenterology surgery, a microscope is fundamentally unnecessary.

Before it wasn't used, now it isn't used, and in the future…… Director Wei watched Zheng Ren's operation and sighed inwardly.

In the future, however, it's hard to say.

The forceps in front of the camera performed blunt dissection on the colon mucosa, then gradually separated the mucosa.

The view was Zheng Ren's microscopic field; the students who had only a vague concept of colon mucosa but no concrete impression burst into exclamations one after another in Classroom 2.

At the same time, the hormone levels in Directors Luo and Wei rose, fell, and rose again, just like the exclamations in Classroom 2.

The students watched for the excitement, but the two heads of Department 912's Gastroenterology Surgery watched for the genuine technique.

The blunt dissection technique was exquisitely delicate, fast, and gentle, swiftly separating the mucosa and submucosa from the muscular layer.

This cadaver specimen is normal human tissue, with no pathology.

But the two directors knew that such fine dissection could not be stopped by anything like precancerous lesions.

If the tumor were any larger, it would exceed the scope of ESD surgery, allowing for open surgical resection.

That is a different concept altogether.

"Director Luo, can you use a microscope?" Director Wei, feeling reflective, asked Director Luo beside him.

"I can't." Director Luo felt somewhat disgruntled; even a standard ESD procedure stripping gastric mucosa, which he himself performed, couldn't be considered perfect, let alone the advanced microsurgical technique for mucosal resection under a microscope.

Director Wei felt reassured and gave a faint smile.

Director Luo felt something odd; he stared fixedly at the screen, watching Zheng Ren separate the colon mucosa and submucosa, with the forceps moving between the muscular and submucosal layers without damaging the muscular layer.

The technique was superb to the point of perfection, and Director Luo felt a sense of awe.

"What do you mean?" he asked casually.

Director Wei merely smiled, also seriously watching Zheng Ren's operation on the big projection, without answering Director Luo's question.

His hand moved slightly, mimicking Zheng Ren's operation. But Director Wei knew that, although it looked like he could do it, it was only appearance.

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

If one were to wear a Microscope, it would be absolutely impossible to perform such proficient micro-manipulation in a cramped space.

He felt somewhat worried; he was still older, and his mastery of new Technique would surely be far inferior to that of younger people.

Going back, he would send Quan Xiaocao into Zheng Lao Ban's group, Director Wei thought to himself. Or later, when he goes out for consultations, he would also find some patients to undergo Endoscopic Submucosal Dissection, and let Quan Xiaocao follow all the Shou Bing.

I don't believe the Gastroenterology Surgery still can't find someone to learn new Technique.

Even if it's just raising someone, we must cultivate a specialist who can perform Endoscopic Submucosal Dissection; otherwise, in a few years the Gastroenterology Surgery will decline just like the Cardiothoracic Surgery.
