Just watching Student Xie’s few strokes, it’s an anatomical drawing from three angles displayed on a piece of paper, fully reflecting the rich path of her three-dimensional thinking guide map. The pen is used to brush over shaded areas, making the drawing more three-dimensional. For detailed parts, the pen’s tip is used to sketch lightly. For her, drawing this thing is indeed easy, nothing could be simpler.

Cao Zhao can imagine the human body in her mind, perhaps like playing with a Rubik’s cube, spinning and spinning, she can turn the human body to whatever plane she wishes, seamlessly without any obstruction.

She’s quite the master of the human Rubik’s cube.

Her hand, white as jade, extends outward like a child’s hand, gently touching Student Xie’s occiput: This brain is good.

Being touched on the head by the Immortal Brother, Xie Wanying dared not move randomly, focusing on finishing the drawing and handing it over to the teacher for review.

A good anatomical drawing, just a glance is undoubtedly faster and more comfortable than reading text. Cao Zhao retrieved the pen from her hand, directly capped it and inserted it back into his white coat’s pocket. Watching her draw along the way, he roughly had an idea in mind.

"Parents."

Oh, Hu Hao quickly responded and walked to the front of the doctor.

"Your child’s condition is just as depicted in this drawing," Cao Zhao said while using his fingers as a teaching pointer to explain the medical lesson to the parents.

At this moment, the parent transformed entirely into the child, carefully listening to the doctor describing the details of the child’s condition.

"The esophagus is here, the trachea is at this place. The hospital you previously visited is an obstetrics hospital, isn’t it?"

"Yes."

"The pediatrics department of an obstetrics hospital isn’t unprofessional, but it may not be comprehensive. Beidu Third Hospital Newborn Department of Surgery is quite average. Their digestive tract imaging isn’t well done. It might be due to urgency to transfer the child to a specialized hospital, without carefully shooting, without imaging the digestive tract. If initially suspected H-type esophageal atresia, you need to make a clear diagnosis to fully understand where the fistula is or if there’s a fistula, a digestive tract imaging with contrast agent needs to be done. How can you let such a small child swallow contrast agent, right? In special situations, a three-chamber two-balloon tube can be inserted and then the contrast agent injected."

"Can’t a CT scan be done?"

"CT can be performed. However, if you’ve gone to hospital for a digestive tract check, you’ve heard doctors mention that for some adult digestive tract examinations, such as involving fistulas, the effect of showing lesions in the digestive tract is very good. CT also has digestive tract imaging."

CT also has digestive tract imaging. For people who don’t understand medicine, it might be unknown knowledge, often thinking a barium meal is just for X-rays. At this stage, many spiral CT technologies are immature, digestive tract imaging has advantages.

"So, it doesn’t necessarily mean my son is—" Hu Hao asked.

"First, the results of the examination need to be clear. A digestive tract imaging needs to be done; if it shows up on the images, we can talk further. If it’s H-type esophageal atresia, there are some highly suspected cases of it, but imaging shows it isn’t. There’s no X-ray sign of contrast agent entering the trachea."

"If it isn’t, then my son’s condition—"

"This involves another problem. If it truly can’t be detected, if the symptoms like the child’s lung infection and pneumoperitoneum don’t disappear, the doctor may have to continue suspecting this direction. It’s possible that you might have to wait until the fistula enlarges a bit for it to be detected. It might also never be detectable, then the doctor must decide whether thoracic surgery is needed to help find the fistula for the child. This is usually done in an emergency when all other options have been exhausted and the family requests a rescue surgery as a last effort."
