Professor Liang really had a heart disease, after reading the information brought by Yang Ping, his face was ruddy, he was full of energy, he no longer coughed, and he ate five bowls of rice at noon, and almost half a roast duck.

The people present are all familiar juniors, and it's not a secret that they can eat, so they don't pay attention to anything at home.

Professor Liang's amount of food should be among the best among the elderly, and Yang Ping suspects that Professor Liang may not have been fed in the past.

Not to say viral acute upper respiratory tract infection? Could it be that so quickly, the virus was killed?

Hu Guolin and Song Yun couldn't understand it at all, and Professor Liang's wife knew her husband's temperament, so she didn't think it was strange.

After lunch, Professor Liang said to his wife, "I'll take my temperature later, and if it's okay, I'll go to work in the hospital." ”

"Today Saturday, why don't you take a break and recuperate?"

Teacher Luo was still a little worried.

Professor Liang said unconvinced: "Five bowls of rice, half of the roast duck, have you ever seen such a patient who can eat?" ”

"Okay, you go, Guolin, you keep an eye on him." Teacher Luo had no choice but to agree, but he was still not at ease, and told Hu Guolin to pay attention to his body, after all, he had been lying down for three days.

"Are there any special patients these days?"

I was bedridden for the past few days, but I just recovered today, so I naturally care about Corey's patients.

"There is a special patient, chordoma, invasion of lumbar 2, 3, 4 vertebrae, during the case discussion decided to do surgery: posterior-anterior-posterior approach, total vertebral resection of three vertebrae, tumor resection, 3D printing titanium alloy artificial vertebrae implantation, posterior pedicle nail system fixation, the operation is too large, the risk is too high, it is estimated that it will take more than 20 hours, we have not arranged surgery for the time being, waiting for you to help check it.

Professor Leung has now handed over the position of head of the department to Professor Wu Guolin, but he still insists on doing ward rounds for surgery.

Professor Liang knew as soon as he heard it: "This is a world-class operation, at present, there are only a handful of people in the country who can do total vertebrotomy surgery, plus the removal of tumors and vertebral reconstruction, I am afraid that there are only three or four hospitals in the country that can do it, this kind of case is relatively rare, Xiehe has done it, Huaxi has done it, at that time it was done with two vertebrae, it took about 15 hours." ”

"Yes, so we have to be well prepared before we dare to do it, and the patients are also coming for our ceiling status." Professor Hu is also very rigorous and can only arrange surgery after making full preparations.

As soon as he heard about the operation, Yang Ping immediately became excited, this kind of surgery is interesting.

The anatomy of the vertebrae is extremely complex, coupled with the invasion of tumors, resulting in an even more complex anatomy, with spinal nerves inside, various criss-crossing blood vessels outside, and an aorta and vena cava in front.

This is a very big operation.

"Let's go to the ward." When Professor Liang heard about this case, he was also doping, and he didn't even need to rest after eating.

---

Prof. Liang, Prof. Hu, Song Yun and Yang Ping walked to Union Hospital.

Professor Leung's home is not far from Xiehe, and he walks for a walk after cooking.

What acute upper respiratory tract infection is, it's all puffy clouds.

When everyone came to the orthopedic ward of Union Hospital, and saw Professor Liang in high spirits, everyone was very puzzled, didn't they mean that they were sick? Doesn't it look like you're sick?

Everyone has just finished their business studies, and there are a lot of people in the doctor's office, and they are all very busy.

When I saw Professor Liang and Director Hu, everyone greeted them respectfully.

There were several doctors who knew Yang Ping, and after recognizing Yang Ping, they were very excited and ran over to talk to Yang Ping.

These doctors have all participated in animal experiments in Guilin, and their names are all signed by Yang Ping's paper.

"Director Hu, take a look at the patient's medical record you mentioned, and we'll discuss it in a few small areas." Professor Liang sat down and instructed Professor Hu Guolin.

Song Yun immediately went to get the medical records, then turned on the computer and put the medical records on the screen.

When everyone saw that Professor Liang was going to see this case now, they all put down their work and listened carefully to the lecture, and the young people all held notebooks in their hands, and the learning atmosphere of Concord was good.

Jing Yunsong, male, 48 years old, low back pain with anterolateral numbness and pain in the right femur was admitted to the hospital for 7 months, physical examination: percussion pain in the spinous processes of lumbar 2, 3 and 4, decreased skin sensation in the lateral film of the right femur, auxiliary examination: lumbar spine MRI was: mass lesions of the 2nd, 3rd and 4th vertebrae of the lumbar spine, considered to be chordoma.

The tumor of the lumbar 2nd vertebra grows into the spinal canal, which has significantly compressed the spinal cord and nerve roots in the spinal canal, resulting in cauda equina lesions. The lumbar 3rd vertebral tumor grows into the abdominal cavity, forming a large soft tissue mass that adheres to the anterior aorta and vena cava; Lumbar 4 spine tumors are much less aggressive.

After Song Yun reported the medical records, everyone began to fall into thought.

Chordoma is a rare malignant tumor that occurs in the skull base bone, vertebrae and sacrum, with an incidence of about 0.8 people per 1 million people per year, and if there is no effective treatment, the 5-year survival rate is only about 30%, which is very low.

Chordoma is not sensitive to traditional chemoradiotherapy, and the tumor --- surgery, radiotherapy, and chemotherapy, so surgical treatment is the main treatment for chordoma.

Chordoma is very prone to recurrence after surgery, and once it recurs, it often damages the nerves of the spinal cord, resulting in incontinence, paralysis of the lower limbs and even death.

Therefore, whether the tumor can be completely removed in the first surgery is the key to the treatment of chordoma.

For Jing Yunsong, 3 of the 5 lumbar vertebrae are involved by tumors, which is equivalent to the tumor has invaded three-fifths of the entire lumbar vertebrae, and to completely remove the tumor, all 3 vertebrae must be removed, and there is no other choice.

The structure of the lumbar spine is very complex, with spinal nerves inside, abdominal aorta and vena cava in front, a large number of blood vessels and muscles around it, and the shape of the vertebrae is irregular and complex.

To remove the vertebrae completely, all normal structures around the vertebrae must be protected and then safely separated from the vertebrae before the vertebrae can be removed.

Therefore, total vertebral resection is also the most difficult and technically demanding operation in the field of spine surgery.

Jingyunsong's tumor involves a long and wide range of lumbar vertebrae, and the tumor grows aggressively around it, forming a mixed state of interpenetration and interweaving with the surrounding tissues.

After the vertebrae and tumor are removed, the spine, which is the axial bone of the human body, is missing three segments, just like a building without load-bearing walls, so it cannot be removed, and the removed vertebrae must be reconstructed.

Traditional titanium mesh and other supports cannot replace the vertebrae for weighing, and 3D printing technology must be applied to create personalized three-section vertebrae in order to rebuild the "load-bearing wall" of the human body.

Mr. Jing has traveled to the top hospitals in the country, and this time he came to Xiehe in the hope of getting the best treatment.

"Surgery is the only treatment, this is unanimous, there is no doubt about the surgical method, all three vertebrae are removed along with the tumor, and then implanted with 3D printed artificial vertebral bodies, and finally the pedicle nails are used to fix the upper and lower normal vertebral bodies together, the operation is very difficult, we did two vertebral bodies last time, Huaxi also did a case, it took fifteen hours." Professor Hu sorted out the medical records and repeated everyone's discussions.

Xiehe is the ceiling of Chinese hospitals, and patients come here without the idea of transferring or going to other hospitals.

This is the last stop on the medical journey.

It's not good to see here, so you can only go back to eat and drink.

The doctors who were familiar with Yang Ping had an idea in their minds: If Yang Ping was asked to do this operation, could he win it? How long will it take?

What exactly is the level of the Golden Knife Award?

What exactly is the top surgeon in the country?
