A group of doctors gathered around the light board again and looked at the film.
After Dr. Sun said this, everyone was obviously more understanding of Gamma Knife and realized some problems.
Seven tumors, numb and numb, the largest one is 2.5, the smallest diameter may be less than 0.3, and they are distributed in different areas. In the eyes of neurosurgeons, if a craniotomy is performed for this kind of situation, they don’t know how many holes will be drilled.
In order to reach all the locations of these tumors, it may be necessary to search the patient's brain to find tumors, which is extremely harmful.
Neurosurgeons are very aware of how difficult it is to operate in certain locations.
"There's one in the brainstem and one in the pons." Dr. Tong pointed to two more critical places on the film.
If you perform surgery in these places, it will almost cost the doctor his life.
What about the Gamma Knife? Compared with the surgical operation of digging out the brain, the Gamma Knife has the advantage of not having to dig out the brain, which is better. The problem is as Dr. Sun said, it is not easy to do the surgery accurately at one time.
It was a little quiet at this moment, everyone knew that Dr. Sun had called everyone to come back for discussion early this morning, and they were obviously waiting for that person to make a high-level speech.
Being looked at by all the teachers, Xie Wanying said: "No."
Everyone was a little dumbfounded. I think you Xie, classmate, actually said the word "no" directly. You were really brave to say it, as if you didn't know that you were facing a radiotherapy boss.
After a while, Dr. Tong was the first to recall the image of being rebutted by Classmate Xie, and laughed on the spot. Perhaps instead of discussing it for himself in front of the patient, Classmate Xie dared to express his opinions more frankly, and he was indeed a stubborn person.
Whether Xie Wanying dares to speak out depends not only on the occasion, but also on the person. If Boss Tong and Boss Sun weren't open-minded, she, Xie Wanying, would never ask for trouble and speak out to offend others.
Look, Teacher Sun didn't mind at all. He smiled and invited her to discuss: "You continue to talk."
From a practical and medical analysis, she could not agree with Teacher Sun's opinion.
Gamma Knife has the best effect on small tumors compared to neurosurgery. Therefore, the small size of the tumor is not the difficulty. There is no need to wait for the tumor to become larger before causing anxiety and pain to the patient. On the contrary, it should be done at once to give the patient confidence and pain.
hope.
"Teacher Sun's concern should be multiple precise positioning." Xie Wanying revealed the technical hurdles that Dr. Sun meant.
A group of non-radiotherapy doctors present almost rounded their mouths and pupils: Is that so?
Everyone turned back to look at Dr. Sun.
Dr. Sun is nodding.
This? Why didn’t they hear what Dr. Sun said just now and only Classmate Xie could hear it? Is it because their brains can’t even compare to Classmate Xie in language comprehension?
"She said last night that she didn't understand Gamma Knife operation at all?!" Dr. Tong suddenly complained about what he said last night. No doubt, this student Xie was slapping himself in the face.
Xie Wanying: Sigh. She really doesn’t know how to operate the page. Like Boss Tong and the others, she just saw the machine today.
The only thing she can do to help is some information she learns in the future.
Gamma Knife is a precise flying knife that kills one tumor at a time. Before killing the next tumor, it needs to be repositioned and the patient's position needs to be rearranged.
Switching to the previous machine, manual repositioning may produce relatively large errors each time. This is also why in the past, for cases with many lesions, it was not possible to accurately position multiple times. The doctor did not feel confident and simply added one.
