The people in Fangze were discussing the matter with great interest.
The National Association was silent.
Now it is Senior Brother Huang and several classmates drinking coffee with Cat and Buddha.
The people on the other side said that Xie cheated patients. It is okay to cheat patients occasionally, but when it comes to academic cheating, Xie is a stubborn person and is the worst at cheating. How can he cheat?
All I can say is that those who don’t know Mr. Xie can only make wild guesses, which makes them laugh their heads off.
“They were very calm.”
It's very stimulating to have a bunch of opponents drinking coffee leisurely next door.
After a doctor in Fangze drank some cold juice, he asked the group of young doctors opposite him: "Did you hear anything?"
Of course I could hear it. Even the worst student here, Wei, didn't pretend to be scared and answered, "Your doctor said it's a problem with the pituitary stalk."
...
...
To further summarize what Dr. Tong said above, the patient's desire to preserve endocrine function, since the pituitary stalk is closely related to endocrine function, actually becomes a requirement of whether the surgeon can help the patient preserve the pituitary stalk during surgery.
Whether or not the pituitary stalk can be preserved during surgery for cranial tibia tumors is a major technical issue. Dr. Tong believed that this was not possible for this patient.
Not only did Dr. Tong say that it was impossible, but overseas doctors tended to reach the same conclusion as Dr. Tong, all based on the patient's preoperative imaging report. From the patient's imaging report, it can be seen that the boundary between the tumor and the pituitary stalk is unclear, and the pituitary stalk is poorly displayed. This means that the tumor may have merged with the pituitary stalk. When the tumor is removed during surgery, it must be removed as a whole and the pituitary stalk cannot be retained alone.
"Yes, our doctor said so." Fang Ze's doctor asked the Guoxie people again, "What do you think?"
This question was only answered by Wei. Wei suddenly had an idea and said, "Our doctor Xie is talking about it."
Dr. Xie's voice further explained came from the machine.
"There are many ways to clinically classify craniopharyngiomas. QST classification is the most commonly used clinical classification method, and the three types it classifies all originate from the pituitary stalk. What I would like to borrow today is another classification method, which divides craniopharyngiomas into six types. I personally think that this method may be more suitable for the origin of your tumor."
This? Could it be that this craniopharyngioma does not originate from the pituitary stalk? Is what Dr. Tong said wrong?
"The six types are pure intrasellar subdiaphragmatic type, intrasellar suprasellar type, supradiaphragmatic parachiasmatic extraventricular type, intraventricular and extraventricular type, paraventricular involving three ventricles type, and pure intraventricular type. From this classification, we can see that not all craniopharyngiomas originate from the pituitary stalk. We must first make it clear that the pituitary stalk mentioned here is different from the pituitary stalk of the origin hypothesis of craniopharyngioma mentioned by Dr. Tong."
What kind of difference is this?
Are there two pituitary stalks?
As mentioned before, craniopharyngioma is a tumor that may develop from embryonic residual tissue. The pituitary stalk in the embryo is definitely not the final form after human development is completed. It is the final form and position after gradual migration and development.
So the origin pituitary stalk that Dr. Tong mentioned is, more precisely, the pituitary stalk tissue at the beginning of the embryo.
In this case, the search for the origin of craniopharyngioma must include the pituitary stalk tissue that remains from the previous embryo, rather than just pointing to the final form of the pituitary stalk.
In other words, the entire developmental pathway of the pituitary stalk may have pituitary stalk tissue.
