X-ray films are far behind CT and MRI.
As I just said, the abdominal X-ray method can only be called economical. What is economical? It mainly helps doctors make a preliminary diagnosis of whether surgery is needed immediately. If it is not possible, surgery must be done. Let's not talk about other distances.
To know the distance accurately, you can use B-ultrasound. Based on the principle that meconium is low-echoic and pelvic floor soft tissue is a high-echo mass, use B-ultrasound to measure the distance between meconium in the lower intestine and pelvic floor soft tissue, and you can roughly know how far the rectum is from the anus. If you want to further determine the development of the anal sphincter, you can use magnetic resonance imaging.
Magnetic resonance imaging is not used in general cases because it is too expensive.
After Xie's supplement, several students looked back at the ultrasound report and basically concluded that it was median anal atresia. To be more precise, it was low median anal atresia, which was slightly different from Pan's previous vague judgment based on x-rays.
Xie Wanying added: "In fact, the high and low levels of this disease classification are mostly explained by family members. Academically, this classification method is not very accurate."
Doctors can only explain to family members in the simplest way. If they explain things in a complicated way, many family members simply cannot understand and have no patience to listen. This is also why the doctor's academic conferences mentioned last time are often held behind closed doors. If you don't understand something, it's better not to let you hear it.
It is necessary to explain. The law requires that the child's condition be explained to the child's guardian.
When Lin Hao and Pan turned around and looked at Xie, their hearts sank: It's over, we couldn't keep up with Xie's pace again.

On the one hand, the knowledge updates in medical textbooks lag behind the reality of medicine and are just rehashing old knowledge. On the other hand, they cannot summarize everything. This is the first time I have focused on this. In other words, doctors and medical students not only need to obtain the latest medical information from various medical journals, but also need to have a broad and in-depth understanding of the history of medical development.
In the international classification, this disease is divided into high, medium and low types, and each type needs to be further classified into without fistula and with fistula. Due to the different sex organs of men and women, it is necessary to further subdivide men and women.
Here is another benefit of doing B-ultrasound examination for this disease: From the academic classification, we can know that this disease is often accompanied by urogenital malformations, and routine urinary tract ultrasound examination and cardiac ultrasound screening are required, which can be done at the same time in the B-ultrasound room.
How important accurate clinical classification is to doctors is something that has been mentioned frequently before and will not be repeated here. In this regard, as a reborn student, Xie has a great advantage in dimensionality reduction, which is unmatched by other students and even teachers.
I just heard classmate Xie say: "For this disease, it is okay not to classify it according to high, medium and low positions, but to classify it directly according to the fistula. Anyway, vaginal fistula and anal stenosis are often seen in low-position deformities, urethral bulb, partial anal atresia without fistula, most rectal scaphoid fistula and rectal vaginal fistula are medium-position deformities, and prostate fistula and vaginal fistula are high-position deformities. It is more convenient to classify the deformity directly, and the surgical procedure should be considered according to the combined deformity rather than simply high, medium and low positions. It is better to classify it into high, medium and low positions and then add the deformity to make it complicated."
The other teachers looked at Dr. Wu Manzhong.
Lin Hao and Pan witnessed the teachers' expressions and finally found a sense of comfort in their hearts. It seems that they are not the only ones who can't keep up with Xie's pace.
