Chapter 1406

"Well done, good." Lei Yinghua looked at the screen and said faintly.

Peng Jia was disappointed and relieved.

His emotions were so complicated that he didn't know how to express himself.

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

Although director Lei Yinghua is over 50 years old, he looks young and handsome. No wonder he was so concerned about the top traffic operating ppt on the screen at the beginning.

Peng Jia thought to herself.

He was involuntarily distracted.

Thinking too much and under too much pressure is a way for the body to protect itself.

At the beginning of the operation, there was some freshness.

The red and white intestines become the background. Endoscopic equipment such as endoscopic scalpels and separators are in the intestines, rigid and slightly boring.

There was no bleeding that caused cardiac arrest, and there was no accident.

All operations are calm and even indifferent.

Although Peng Jia knows that this situation means that the operator has a good grasp of the operation, his analysis from the perspective of viewing is not the best way.

Ups and downs can be attractive.

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

Peng jianeng felt that his breathing was uneven.

At some moments of dissociation and polypectomy, Lei Yinghua's breathing sound will disappear briefly.

58 ′ 22 ", Lei Yinghua didn't feel tired. When a polyp with a diameter of 2-3cm appeared in the endoscopic field of vision, his back straightened up.

The spraying pipe evenly sprays the dye, and the endoscope is cut with a knife, which is free layer by layer.

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

"Director Lei, this polyp should invade the muscle layer." Peng Jia understood something. He whispered around Lei Yinghua.

"Yes." Lei Yinghua said in a deep voice: "when free, the muscular layer can easily penetrate, leading to intestinal rupture."

Peng Jia is worried.

But when he saw the separating pliers on the screen, he had an inexplicable confidence.

Can boss Zheng make mistakes?

impossible!

This confidence is inexplicable. It is accumulated by countless operations, but Peng Jia didn't notice it.

After the incision, the picture on the screen finally paused. It seems that the operator also realized that it is different from the smaller polyps before.

However, after 6 ", the visual field began to change and the resolution of the endoscopic lens was maximized.

Lei Yinghua knows that some endoscopes have this function.

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

He looked at the camera in amazement. The colonic mucosa stretched out many finger like protrusions into the lumen, each of which looked so huge, like a forest.

The painting style suddenly changed from rigorous endoscopic surgery and modern science and technology to fantasy painting style. Lei Yinghua and Huo stood up at once.

However, he then realized that his behavior was a little stiff and too excited. He forgot that he was seeing an ESD operation by a "younger" doctor.

He was embarrassed.

"Director Lei, will you tell us something? We can't understand it." Peng Jia quickly stood up and said humbly.

"OK." Lei Yinghua said immediately and walked up to the LCD screen.

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

He also saw the intestinal anatomy in high-power microscopic mode for the first time. But his profound theoretical foundation cleared all obstacles for him.

"Here is the villus in the small intestinal mucosa, and it is also a very important digestive organ." Lei Yinghua used a laser pen to point to the "huge" fluff on the screen, trying to keep calm and calm.

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

The picture moves slightly, like a microscope holder supporting the lens.

The operator's operation is slow, and he is also looking for anatomical structures.

"Here is the small intestinal gland, opening between villi. If pathological examination can find that the gland cells are columnar cells or goblet cells." Lei Yinghua pointed to a point that loomed only after several degrees of magnification and said.

"The mucosa of the small intestine also has muscle layer, inner ring and outer longitudinal smooth muscle..." just said here, the free pliers appeared in the screen.

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

But Lei Yinghua knew that it was just a head, and the operator controlled the progress of the separating forceps.

This is 50 times the field of vision. Can it be controlled so accurately by artificial means? Lei Yinghua was in a trance.

However, the separating forceps did not separate directly. The endoscopic scalpel appeared, clicked the muscular layer of the mucosa, and then disappeared.

It turned out that when Lei Yinghua saw this paragraph, he understood what happened to the slightly indifferent operation he had seen before.

No wonder there is so little bleeding!

The operator did not cut the mucosal muscle layer violently with a scalpel at all, but gently, and then made blunt separation with separation forceps.

Obviously, the operation in the 50x field of vision fully shows the operator's surgical level.

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

However, Lei Yinghua, a master of ESD, has changed others. Even from a high-power perspective, it is estimated that 99% of doctors can't understand the strength of operation.

Some steps are even considered invalid.

"Here is the smooth muscle of the inner ring of the intestinal mucosal muscle layer. It is very thin and difficult to see." Lei Yinghua has begun to get a little excited.

The textbook says so, but he has never seen it so clearly.

It's a little different from what I imagined. Lei Yinghua secretly wrote down the microanatomy while explaining.

The separating forceps move gently under the inner ring smooth muscle of the mucosal muscle layer and swim in the submucosal connective tissue between the inner ring smooth muscle and the intestinal muscle layer.

Lei Yinghua didn't see the confusion of the operator about the micromanipulation. This extremely fine micromanipulation does not bring a burden to the operator. As before, the operation is done slowly.

"Here are the blood vessels in the intestinal submucosa, MD, how can they be so thick..." Lei Yinghua couldn't help sighing.

Usually this time, he just passes by.

At 50x field of view, a thick blood vessel appears in the field of view. The operator stopped and separated the connective tissue with a separating forceps. Then he saw an electric burn. Gently, a wisp of smoke burned the blood vessels.

The broken end coagulated without any bleeding.

"The operation is very fine. The blood vessels in this position are difficult to see with the naked eye." Lei Yinghua's voice was a little astringent.

He finally found out why the operation was a little slow before.
