Zhao Yuan wanted to use two new surgical methods in this operation.

The first is nerve fiber stripping.

In this technique, all gliomas in the brain are removed along the nerve fibers.

Normal tumor resection is the removal of the tumor in pieces, which can easily lead to residual tumors, and can also easily damage the nervous system, causing hemiplegia coma or other adverse effects.

Sounds a bit puzzling.

In fact, in the final analysis, it is the difference between two words, one is to cut and the other is to peel.

The glioma is removed in its entirety along the nerve fibers.

It not only maximizes the removal of the tumor, but also maintains the integrity and function of the nerve.

This technology has been proposed in the world, but it is rarely widely used.

Regina sighed, "Supporters of the Yasargil school have tried this technique, but the success rate is too low and the operation is too difficult, and it is not accepted by the academic community. ”

"According to some research results, glioma will invade and spread along the anatomy of the white matter nerve fiber tract in the central nervous system.

By resynthesizing the established bundles of white matter fibers, the spatial relationship between the bundles and the tumor can be clearly visualized, so as to clarify the boundaries.

However, although there are many auxiliary means, such as navigation drift, intraoperative MRI, etc., how to find the boundary of tumor dissection is mainly screened by the doctor's hands and eyes. ”

Professor Cheng agreed, and Wang Enlin explained more professionally.

To put it simply, in order to do a good nerve fiber stripping, the doctor's experience is particularly crucial, and the auxiliary system cannot help.

Professor Cheng began to break down Zhao Yuan's technical movements.

"Due to the infiltrative or expansive growth of glioma, Zhao Yuan first chose partial resection within the tumor to achieve the purpose of volume reduction, which can maximize the protection of the surrounding brain tissue and is not conducive to the subsequent tumor stripping operation.

The tumor is then peeled along the nerve fibers, and typically, the tumor tissue is grayish-white, grayish-yellow, or grayish-red, while normal brain tissue is lighter-colored, white or yellowish-white.

Of course, the most important thing is to rely on the feeling, when the tumor is close to the border, the texture of the tumor tends to be harder, and the texture becomes softer outside, and the area between soft and hard is the boundary of the tumor. ”

If it is a layman, in the face of Professor Cheng's interpretation, it is estimated that he is confused.

However, Professor Cheng explained in the observation area that it can play a good guiding role.

The doctors in the observation area are among the best in the field of neurosurgery in China.

Maybe there was some confusion at first, but under Professor Cheng's analysis and dissection, it gradually became clear.

Unconsciously, Zhao Yuan has entered the most critical part - peeling off the tumor.

Professor Cheng began to lecture again: "There are two difficulties in this.

First, the peeling needs to be done by means of a control instrument, which is different from the peeling of an orange by a normal person.

Second, the peeling needs to be extremely precise, the action should be gentle, and the tumor should be torn off completely like tearing a postage stamp. If the lesion is accidentally torn, it becomes a big problem to find the edge of the peel again, which is not only easy to cause damage to the brain tissue, but also easy to cause the residual tumor. ”

In the operating room, Zhao Yuan was also holding a small class, operating instruments while sharing his feel with Qin Yi.

"Low-grade gliomas are very tough, high-grade gliomas have soft tumors in the center and hard and tough peripherals. It should be noted here that the relatively tough and tough areas around the periphery are also tumors, tumor tissues that migrate along nerve fibers.

Don't mistake glial growth bands for residual tumors.

Regardless of whether the tumor is high or low, the detachment along the nerve fiber can effectively avoid tumor remnant and nerve damage. ”

Qin Yi silently remembered it in his heart, and according to Zhao Yuan's request, he touched the periphery of the glioma by manipulating the instrument.

This experience is invaluable.

If you are a doctor in charge of surgery, you will not be able to divide your energy and teach you how to distinguish the characteristics of different gliomas on such a critical occasion.

Wang Enlin's eyes flashed with a strange light.

Judging from the smoothness of the operation, Zhao Yuan's operation has basically achieved its goal.

At the same time, he demonstrated the advantages of nerve fiber stripping.

In the process of removing tumors, it plays a protective role in nerve function.

Bleeding is rare, and if the tumor is removed conventionally, it can easily lead to bleeding.

In addition, it helps to reduce stress.

The outer layer of malignant tumor tissue is hard and tough, which will support and bind the brain tissue like armor.

Conventional tumor resection generally does not remove this part of the tissue.

However, stripping can also be referred to as "peeling".

It will uproot the peripheral sclerosis tumor, which is more conducive to the patient's recovery.

Four hours passed.

Tumor tissue was removed one after another.

The experts in the observation area realized that the operation was almost successful.

"It's worth the trip to see this kind of high-level surgery on site."

"Zhao Yuan's ability is too strong, it's only been a long time, and he has directly created a new technique, alas, I feel that the innovation of the technique is as simple as eating for him."

"The main thing is that the basic skills are solid enough, and with this confidence, you can challenge the forbidden area."

"Hey, it looks like the operation isn't over yet."

"There's a new technique?"

Just when everyone felt that the operation was coming to an end, Zhao Yuan brought another surprise.

Generally, after the tumor is removed, the final touches follow.

But Zhao Yuan has added a whole new element here.

Intraoperative radiotherapy!

It is difficult to completely remove the brain tumor by surgery alone, and the remaining cancer cells and tissues are scattered around the lesions, and some of them are very hidden, so it is difficult to remove the cancer cells in depth.

Zhao Yuan put the adapter into his brain, and then used low-energy X-rays to deliver targeted radiation to brain tumor tissue in the human body.

The radiation energy produced does not harm the patient's brain, which can save the patient from having to undergo multiple radiotherapy treatments after surgery.

In addition, in intraoperative radiotherapy, through precise target positioning, there will be fewer toxic and side effects caused by radiotherapy.

A smile appeared at the corner of Wang Enlin's mouth.

When positioning the target area, Zhao Yuan consulted Wang Enlin.

Because Wang Enlin is a top expert in this field, as for intraoperative radiotherapy, Wang Enlin has been studying this idea recently.

Seeing someone else's surgery has their own shadow, there will be a strong sense of substitution.

It seems that the great achievements also have their own merits.

"It's amazing. One operation combines multiple new surgical procedures. The gold content is too high. ”

"After watching this surgery, I don't feel anything about other people's surgeries."

"No wonder people are qualified to host the national summit, just with this technology, who else is not convinced?"

The experts who had done the demonstration surgery before were secretly glad that their operations had been completed, and the pressure on the experts who did the demonstration surgery next would be great, and it would inevitably be compared with Zhao Yuan's surgery.

Although they are all famous celebrities in the country, the innovation of the technique is not so simple, just like dumplings.

One operation is interspersed with so many exclusive "labels"!

That's awesome!

It's so rebellious!

Gu Yong stood in the crowd, and the few hostilities he had towards Zhao Yuan before completely disappeared.

Gu Yong admired Zhao Yuan from the bottom of his heart.

Both Shengyu and He Shengliang, that is the feeling between opponents in a level.

In front of Zhao Yuan's amazing talent and excellent skills, he is completely a younger brother.

"Ask for a guaranteed ticket, it will be wasted if it expires!"
