All the teachers have sharp eyes.
Xie Wanying said bluntly: "Teacher Jin, I estimate that if she is given a shunt surgery, she can only undergo two or three incisions."
"Yeah." Doctor Jin responded first, then suddenly realized, and then said "ah" like a soprano.
Dr. Jin is a neurologist and of course knows how to perform the specialized surgery ventriculoperitoneal shunt.
After hearing Dr. Jin's surprised cry, a group of young doctors and medical students at the scene had questions.
"What does the two or three knives Yingying mentioned mean?" Wei Shangquan asked classmates Pan and Geng in a low voice.
What did Dr. Jin shout?
"Wei Shangquan, do you know that you are here for an internship in neurosurgery?" The other two students, Pan and Geng, suspected that he was not doing his job properly and was not reviewing his neurosurgery lessons seriously, otherwise how could he not even know this common neurosurgery operation.
The process of ventriculoperitoneal shunt surgery is simply as follows: a hole is drilled in the brain, and a drainage tube is inserted into the ventricle, which is the "pool" containing cerebrospinal fluid, to drain out the excess cerebrospinal fluid. Where does the released cerebrospinal fluid go? Does it go to a urine bag like a catheter and then be poured out?
...

Hanging a bag all day long will reduce the patient's quality of life and make infection more likely.
An infection of the cerebrospinal fluid is far more serious than a urinary tract infection.
It is best to drain the cerebrospinal fluid to a place where the human body can recycle the cerebrospinal fluid instead of external drainage.
As mentioned above, ventriculostomy.
What are the places in the human body that can absorb "water"?
Theoretically speaking, as long as there are pipes in the human body through which blood flows, "water" can be recycled. For example, the heart and anus are all good pools for collecting "water".
Historically, many patients have been used as guinea pigs for these surgeries. The best route, according to statistics, is to drain into the abdominal cavity. So the most common hydrocephalus ventriculoperitoneal shunt is to place the other end of the drainage tube into the abdominal cavity.
One end of the tube is on the head and the other end goes to the stomach, and the fluid inside is cerebrospinal fluid, which must be avoided from contamination.
How long should this pipe be?
Moreover, if the cause of the disease cannot be resolved for patients who undergo shunt surgery, they will have to wear the tube for the rest of their lives.
Can the patient be allowed to spend the rest of his life with a drainage tube?
It is best not to do this. Burying the tube inside the human body, like a blood vessel in the human body, can better avoid accidents such as contamination, twisting and breaking of the tube.
An important step in this operation is the creation of a subcutaneous tunnel.
If the human body is covered with skin, the subcutaneous layer is like a container, containing all kinds of organs and tissues.
The tube enters subcutaneously, and unlike blood vessels, the subcutaneous space does not have walls to constrain the tube, so it is a relatively free world.
The doctor needs to ensure that the tube smoothly reaches the target abdominal cavity through the most convenient and unobstructed shortcut, rather than letting the tube move around and go nowhere or get tangled in circles.
At the same time, the subcutaneous space is not a completely free world. There may be obstructions in some places, making it difficult for the tube to pass through.
The main reason is that the distance from the head to the abdomen is too long. Doctors sometimes find it difficult to use force when they want to pierce it, and it is difficult to detect what is causing the problem, which leads to failure.
In this case the relay point must be opened.
The common practice in this operation is to open two or three incisions in the middle to grasp the tube for relay threading.
Xie said that only two or three cuts are needed, and the incisions at the starting and ending points cannot be avoided, which means that she thinks she only needs to make one or zero relay points.
No wonder Dr. Jin asked first: Is it true or false?
