"Yiyi, do you have any objection to my judgment?"
Yan Feifan waited for a moment. When Yiyi didn’t respond, he knew he must be right.
Based on his understanding of Yiyi, if he had made the wrong judgment, it definitely would have popped up to mock him a little.
Yan Feifan looked at Mr. Wan and said, "Mr. Wan, I..."
Mr. Wan held up a hand, stopping him. "Don’t state your judgment just yet."
He looked at Li Hao, Gao Jin, and Yu Suye and ordered, "Your turn. Be quick about it."
This time, Yu Suye and Gao Jin stepped forward together.
However, Gao Jin gallantly made a "please go first" gesture, letting Yu Suye proceed...
Yu Suye, Gao Jin, and Li Hao each asked the pregnant woman some questions. They also primarily used palpation, at most with the help of a stethoscope, to examine her abdomen.
The pain point Yan Feifan had located by pressing was, naturally, the area the three of them focused on examining...
Mr. Wan waited until Li Hao had also finished his examination, then asked directly, "Mr. Gao, give me your diagnosis!"
"Appendicitis!" Gao Jin’s reply was crisp and direct.
"Dr. Li, what about your diagnosis?"
Li Hao hesitated for a moment, then replied softly, "Inflammation or a stone in the bladder or urethra."
Mr. Wan looked at Yu Suye, his expression impassive, and asked, "Do you have any new ideas?"
Yu Suye bit her lip lightly and said matter-of-factly, "Mr. Wan, with the current information, I can’t reach a definitive diagnosis. I can only rule out gastrointestinal diseases and common causes of an acute surgical abdomen."
Mr. Wan just shook his head and said with some disappointment, "Great. Three people, three different answers."
He looked at Yan Feifan and said, "Xiaoyan, are you going to give me a fourth answer?"
Yan Feifan grunted in affirmation. "Mr. Wan, my diagnosis is torsion of a fallopian tube cyst."
Torsion of a fallopian tube cyst is a type of gynecological acute abdomen. Approximately 10% of ovarian or fallopian tube cysts can undergo torsion.
It often occurs with a sudden change in body position, strenuous exercise, or changes in the size and position of the uterus during pregnancy and the puerperium.
Its typical symptom is the sudden onset of severe, one-sided lower abdominal pain after a change in position, often accompanied by nausea, vomiting, or even shock.
Sometimes, an incomplete torsion can spontaneously resolve, and the abdominal pain subsides along with it.
The moment Yan Feifan stated his judgment, it immediately drew a challenge from Gao Jin.
"The fallopian tubes are so deep, and they’re obscured by the uterus. How could you possibly feel them?"
"Mr. Yan, you just inferred this diagnosis, didn’t you?"
Yan Feifan explained, "It’s true that the fallopian tubes are very deep. And with the compression from the patient’s uterus, they are difficult to palpate from the abdomen."
"However, if the cyst has reached a size of at least three by five centimeters, it’s still possible to detect something if you feel for it carefully..."
Seeing the young doctors starting a live discussion, the husband couldn’t take it anymore and said with a note of dissatisfaction, "Mr. Wan..."
Mr. Wan held up a hand, stopping Yan Feifan, Gao Jin, and the others. He explained to the couple, "In the current situation, if we do a color Doppler ultrasound of the abdomen, we could reach a conclusion quite easily..."
"No..."
The pregnant woman cut Mr. Wan off. Gritting her teeth against the pain, she said, "The radiation will harm the baby. It won’t just affect brain development; there’s a high chance it will cause a deformity."
"Color ultrasounds, CT scans, and the like are absolutely not allowed."
Mr. Wan had a major headache. This was a couple who had been duped by so-called experts into following pseudoscientific parenting advice.
He pointed a finger at Yan Feifan and ordered, "Xiaoyan, you have a good memory. Give them a quick science lesson."
Yan Feifan cleared his throat and said, "B-scans, color Doppler ultrasounds, CT scans, X-rays, and MRIs are all common clinical diagnostic tools."
"Among them, B-scans and color Doppler ultrasounds use sound wave reflection, forming an image on the device based on the different echoes."
"Therefore, color Doppler and B-scan ultrasounds have no radiation, which is why they are safe for pregnant women."
Yan Feifan paused briefly, then continued, "As for MRI, or magnetic resonance imaging, it mainly uses the principle of electromagnetic wave imaging. The ’nuclear’ part in its full name refers to the nucleus of a hydrogen atom."
"An MRI machine provides a magnetic field for the human body. In this field, the hydrogen nuclei in your body begin to move in a regular pattern, which is then processed by a computer to form an image."
"Therefore, just like an ultrasound, an MRI has no radiation and is also safe for pregnant women."
Yan Feifan spoke concisely and quickly, "X-ray examinations do have radiation. A single X-ray exam has a radiation dose of about 0.02 to 0.1 mSv."
"For comparison, every one of us receives nearly 2.0 to 3.0 mSv of natural background radiation every year from daily life."
"A small number of X-ray exams will not cause harm to the body."
"As for CT scans..."
Yan Feifan stated bluntly, "The radiation dose is higher. While the scan is more precise, the radiation dose is about ten times that of an X-ray."
"A standard chest CT scan has a radiation dose of about 2 to 5 mSv. But even so, a CT scan is still within the safe range."
"According to clinical standards, as long as the human body does not receive more than 100 mSv of radiation in a year, it is considered a relatively safe range."
Yan Feifan added, "X-rays and CT scans are not recommended for pregnant women, but if absolutely necessary, the corresponding examination can be performed while taking protective measures for the fetus."
"In such cases, the possibility of a small number of short-duration exams causing adverse effects on the fetus is very small."
