Xie Wanying said it bluntly: "Teacher Jin, I estimate that if we perform shunt surgery, we can only give her two or three surgeries."
"Yeah." Dr. Jin responded first, then suddenly realized, and then said "Ah" like a soprano.
Dr. Jin is a neurologist, so he certainly knows how to perform ventriculoperitoneal shunt surgery.
Hearing Dr. Jin's surprised voice, a group of young doctors and medical students at the scene had questions.
"What does Yingying mean by two or three swords?" Wei Shangquan whispered to classmate Pan and classmate Geng.
What did Dr. Jin shout?
"Wei Shangquan, do you know that you are here to intern in neurosurgery?" The other two students, Pan and Geng, suspected that he was not doing his job properly and had not reviewed his neurosurgery lessons carefully. Otherwise, how could he not even know this common neurosurgery operation?
In simple terms, the process of ventriculoperitoneal shunt is as follows: drill a hole in the head, insert the drainage tube into the ventricle of the "pool" containing cerebrospinal fluid, and drain out the excess cerebrospinal fluid. Where does the released cerebrospinal fluid go? It is connected like a urine catheter.
Will the urine bag be thrown away again?
Hanging a bag all day will reduce the patient's quality of life over time and may lead to infection.
A cerebrospinal fluid infection is much more serious than a urinary tract infection.
It is best to drain the cerebrospinal fluid without draining it externally to a place where the body itself can recover cerebrospinal fluid.
Such as the ventriculostomy mentioned above.
Where are the places in the human body that can absorb "water"?
Theoretically speaking, as long as there are pipes in the human body that have liquid flow, "water" can be recovered. For example, the heart and bladder are all good pools for collecting "water".
From the history of medicine, many patients have become guinea pigs for doctors' operations. In the end, statistics were screened out, and the best route is drainage into the abdominal cavity. Therefore, the most common hydrocephalus ventriculoperitoneal shunt is to put the other end of the drainage tube.
Enter the abdominal cavity.
One end of the tube is on the head and the other end goes to the stomach. What goes inside is cerebrospinal fluid that needs to be avoided from contamination.
How long should this pipe be?
Moreover, patients who undergo shunt surgery will have to wear the tube for the rest of their lives if the cause of the disease cannot be solved.
Can patients be allowed to wear external drainage tubes for the rest of their lives?
It is best not to do this. Burying the tube inside the human body, as if it becomes a blood vessel in the human body, can better avoid accidents such as contamination, twisted tubes and broken tubes.
An important step in this surgery is the creation of a subcutaneous tunnel.
The human body is covered with skin, and the subcutaneous layer is like a container, which contains all kinds of organs and tissues.
The tube goes under the skin. Unlike blood vessels, the subcutaneous layer has walls that can bind the tube. It is a relatively free world.
The doctor needs to ensure that the tube reaches the target abdominal cavity smoothly from the most convenient and smooth shortcut, instead of letting the tube move around and wander around in circles or become kinked.
At the same time, the subcutaneous is not a completely free world. There may be obstacles in some places, making it difficult for the tube to pass.
The main reason is that the distance from the head to the abdomen is too long. Sometimes doctors want to force the insertion, but sometimes it is difficult to use force. It is also difficult to detect what is causing it, and it is easy to fail.
In this case the relay point must be opened.
The usual practice of this surgery is to open two to three incisions in the middle to grab the tube and perform relay insertion.
Classmate Xie said that it only takes two or three cuts, and the incisions at the beginning and end are unavoidable. This means that she thinks she only needs to make one or zero relay points.
No wonder Dr. Jin wanted to check first: Is it true or false?
