"It's done well, very well." Lei Yinghua looked at the screen and commented faintly.

Peng Jia was a little disappointed and a little relieved.

He has a complicated mood and doesn't know how to express it himself.

While watching the operation on the screen, he glanced at Lei Yinghua's expression.

Although Director Lei Yinghua Lei is over fifty years old, he is young and handsome. No wonder he was so concerned about the top traffic that operates on the screen at the beginning.

Peng Jia thought to himself.

He couldn't help but get distracted.

If you think too much and have too much pressure in your mind, this is a way for the body to protect your hands.

When I first saw the surgery, it was a little fresh.

The red and white intestines became the background, and endoscopic equipment such as endoscopic incision and separator were moved coldly, without any change at all, and they were slightly indifferent.

There was no bleeding that caused the heartbeat to stop, and there was no accident.

All operations are calm and even a little indifferent.

Although Peng Jia knew that this situation meant that the surgeon was fully aware of the operation, he was not the best way to analyze it from the perspective of viewing.

Can the ups and downs attract people?

But not everyone has the same idea as Peng Jia. Director Lei Yinghua Lei looked at the LCD screen without blinking.

Peng Jianon felt that his breathing was not even.

At some moments when the polyps are removed, Lei Yinghua's breathing will disappear briefly.

58′22″, Lei Yinghua did not feel tired. When a polyp with a diameter of 23 appeared in the endoscopic field of view, his back straightened.

Spray the dye evenly with the spray tube, cut it with the endoscopic incision blade, and free it layer by layer.

It seems that the savage did not realize the difference between this large polyp and other polyps.

"Director Lei, this polyp should have invaded the muscle layer." Peng Jia also understood a little bit, and he asked quietly beside Lei Yinghua.

"Yes." Lei Yinghua said in a deep voice, "When you are free, the muscle layer can easily penetrate, causing intestinal rupture."

Peng Jia was a little worried.

But when he saw the separation pincers on the screen, he didn't know where a strange confidence came from.

Can Boss Zheng make mistakes?

Impossible!

This confidence is inexplicably accumulated by countless surgeries, but Peng Jia did not notice it.

After cutting, the screen finally paused, and it seemed that the craftsman realized that this place was different from the smaller polyps before.

But after 6″, the field of view begins to change, and the resolution of the endoscopic lens is maximized.

Lei Yinghua knows that some endoscopy have this function.

But I have never used it myself, and doctors in the laparoscopy room rarely use it. Because this is already at the level of microsurgery, gastrointestinal surgery has nothing to do with microsurgery.

He looked at the camera in shock, and many finger-like protrusions stretched out into the lumen of the colon mucosa, each of which looked so huge, like a forest.

The painting style suddenly changed, from rigorous endoscopic surgery, and modern technological style directly changed to fantasy painting style. Lei Yinghua stood up.

However, he then realized that his actions were a bit stiff and too excited, and forgot that he was watching an ESD operation of a "school" doctor.

He was embarrassed.

"Director Lei, please tell us, we can't understand it anymore." Peng Jia quickly stood up and said humbly.

"Okay." Lei Yinghua said immediately, and walked to the LCD screen with his foot.

An assistant handed over the laser pen, and Lei Yinghua opened the laser pen.

It was the first time he saw the intestinal anatomy under high-power microscopy mode. However, his deep theoretical foundation cleared all obstacles for him.

"This is the villi in the mucosa of the small intestine and is also a very important digestive organ." Lei Yinghua used a laser pen to tap the "huge" villi that appeared on the screen, trying to keep calm and calm.

But he didn't notice that his voice had begun to squeak.

The picture moves slightly, like a microscopic fixture supporting the lens.

The operator was slow in operation and he was also looking for anatomy.

"This is the small intestinal gland, with the opening between the villi. If a pathological examination can reveal that the gland cells are columnar cells or goblet cells." Lei Yinghua pointed a point that appeared vaguely after a few degrees of magnification, and said.

"The mucosa of the small intestine also has muscle layers, inner rings, outer longitudinal smooth muscles..." As soon as he said this, free forceps appeared on the screen.

On the LCD screen, the pliers are so huge that they seem to occupy more than half of their field of view.

But Lei Yinghua knew that this was just a head, and the surgeon controlled the movement of the separation forceps.

This is 50 times the vision, which can be controlled so accurately by artificial means? Lei Yinghua is a little dazed.

However, the separation forceps did not separate directly. The endoscopic incision appeared, and the muscle layer of the mucosa was clicked, and then disappeared.

So that's how it is. When Lei Yinghua saw this paragraph, he understood what was the slightly indifferent operation he had seen before.

No wonder there is so little bleeding!

The surgeon did not violently cut the mucosal muscle layer with an incision, but instead pointed it lightly and then used separation forceps for blunt separation.

It is obvious that the operation in the 50-fold field of vision fully demonstrates the surgeon's surgical level.

Because under ordinary vision, it is impossible to find that the craftsman has done so many operations.

But even if it is a master like Lei Yinghua who does ESD, if it is replaced by others, even under high-power vision, the 99 doctors are probably not able to understand the operation.

Some steps may even be considered invalid.

"Here is the smooth muscle of the inner ring of the intestinal mucosa muscle layer. It is very thin and difficult to see." Lei Yinghua was already a little excited.

This is written in textbooks, but he has never seen it so clearly.

It was a little different from what I imagined. Lei Yinghua explained, while secretly recording the microscopic anatomical structure in his heart.

The separation forceps gently move under the inner ring smooth muscle of the mucosal muscular layer, wandering in the submucosal connective tissue between the inner ring smooth muscle and the intestinal muscular layer.

The movement was not fast or slow, and Lei Yinghua did not see any confusion among the operators about microscopic operations. This extremely fine microscopic operation did not burden the operators. Just like before, the operation was being performed slowly.

"This is the blood vessel in the sublayer of the intestinal mucosa. How could it be so thick..." Lei Yinghua couldn't help but sigh.

Usually, he passes by.

At 50 times the field of vision, a thick blood vessel appeared in the field of vision. The surgeon stopped and used separation forceps to separate the connective tissue. Then he saw electric burning. He pointed it gently and the blood vessel was burned after a wisp of blue smoke.

The broken end condensed without a trace of bleeding.

"The operation was done very carefully, and the blood vessels at this location are difficult to see with the naked eye." Lei Yinghua's voice was a little astringent.
