A group of doctors gathered around the light board and looked at the film.
After Dr. Sun said this, everyone became more aware of some problems with Gamma Knife.
There are seven tumors, some are small, the largest is 2.5, and the smallest is less than 0.3 in short diameter, and they are distributed in different areas. In the eyes of neurosurgeons, if a craniotomy is performed, it is unknown how many holes should be drilled to reach all the locations of these tumors, and it may be necessary to turn the patient's brain over to find the tumor, which is extremely harmful.
Neurosurgeons are well aware of how difficult some areas are to operate on.
"There is one in the brain stem and one in the pons." Doctor Tong pointed to two more critical places on the film.
If surgery is performed on these parts, it will almost cost the doctor his life.
What about the Gamma Knife? Compared to surgical procedures, the Gamma Knife has the advantage of not having to dig into the brain, which is better. The problem is, as Dr. Sun said, it is not easy to get it right in one go.
It was quite quiet at the moment. Everyone knew that Dr. Sun had called on everyone to come back for discussion this morning, and he was obviously waiting for that person to make a profound speech.
Being stared at by all the teachers, Xie Wanying said, "No."
...
...
Everyone was a little stunned. It was really bold of you, Xie, to say "no" directly, as if you didn't know that you were facing a radiotherapy expert.
After a while, Doctor Tong was the first to recall the scene of being refuted by Xie, and laughed on the spot. Maybe Xie was more daring to express his own opinions now that he was not discussing with the patient, and he was indeed a stubborn person.
Whether Xie Wanying dared to speak directly or not depended not only on the occasion but also on the person. If it weren't for the open-mindedness of Tong Da Lao and Sun Da Lao, Xie Wanying would never have offended others by speaking out.
Look, Teacher Sun didn't mind at all. He smiled and invited her to discuss: "Go on."
From a medical perspective, she could not agree with Mr. Sun's opinion.
Gamma Knife has the best effect on small tumors compared to neurosurgery, so the small size of the tumor is not a problem. There is no need to wait until the tumor is large to create anxiety and pain for the patient. On the contrary, it should be done in one go to give the patient confidence and hope.
"What Dr. Sun is worried about should be the multiple precise positioning." Xie Wanying revealed the technical level that Dr. Sun implied.
The group of doctors present who were not experts in radiotherapy almost narrowed their mouths and eyes: Is that so?
Everyone turned around and looked at Dr. Sun.
Doctor Sun nodded.
This? Why didn't they understand what Dr. Sun said just now, but only Student Xie did? Is it because their brains can't even compare to Student Xie's ability to understand language?
"She said last night that she didn't know anything about how to operate a gamma knife?!" Doctor Tong angrily complained about what Xie had said last night. Undoubtedly, this student Xie was slapping herself in the face.
Xie Wanying: Oh my god. She really doesn’t know how to operate the page. She just saw the machine today, just like Tong Da Lao and the others.
The only thing she could do to help was some information she learned in the future.
The gamma knife is a precise flying knife that can kill one tumor at a time. Before killing the next tumor, it needs to be repositioned and the patient's position needs to be readjusted.
If the old machines were used, manual repositioning would result in large errors each time. This is also why in the past, for cases with many lesions, doctors were not confident enough to perform a whole-brain scan when they could not accurately position the lesions multiple times.
The new machine is different.
