"Before answering this question, everyone should think back to the anatomical structure of the tube wall. How many layers are it divided into?"

When Chen Qi asked this question, it was like a teacher asking a student. Everyone was quiet in an instant. Even the big guys like Principal Li and Dean Wang were in a hurry, trying to remember.

Director Jia Liangcai of the Department of Internal Medicine was sitting in the auditorium and laughed at the directors of the Department of Surgery next to him:

"Hey, who is it? Lao Jin, Lao Liu, Lao Shen, come on, come and answer. Aren't you just trying to compete with our internal medicine department? Now the dean is asking questions, so don't be a coward.

."

"Damn, you know it's amazing. You can memorize several anatomical structures and it's so interesting. Come on, come on, I'll give you this patient. Are you capable of operating under the knife? You probably fainted when you saw the blood flowing out, right?"

/p>

As soon as Director of Surgery Jin Peilin said these words, there was a burst of cheers from the surgical crowd.

Because of Chen Qi's question, surgeons and surgeons started fighting each other again, and the Ruoda auditorium was as lively as a Spring Festival gala.

In the operating room, Professor Zhang acted like an intern and answered honestly:

"The normal wall of the digestive tube generally consists of four layers, including the mucosal layer, submucosal layer, muscularis propria and serosal layer. The tube does not have a serosal layer, but has an outer membrane, which is composed of some connective tissue. It is also a four-layer structure.

”

Chen Qi chuckled lightly: "He is indeed a professor from Fudan University, and he is worthy of learning from all of us. He can answer such basic questions casually."

As soon as these words came out, Principal Li, Dean Wang, Director Xu, Guo Shuji, Director Zhu and other big bosses all blushed.

This is the biggest difference between academic experts and clinical experts. They use their brains instead of just cutting things with a knife.

Professor Zhang is playing away from home and is still here to study, so I would like to say a few words of humility:

"Wherever, Dean Chen's thinking is not so wild and unconstrained."

It is not convenient for Chen Qi to formally teach surgery, so he continues the previous topic:

"We all know, ahem, some of our doctors know that the submucosa of the esophagus is composed of loose connective tissue. If you look carefully at the steps I am doing now, it is to inject physiological saline into the submucosa, which can make the submucosa bulge and

The muscularis propria is separated.

Then I use the electric knife to insert into the incision and cut off or melt away all the tissue under the mucosal layer. Do you think this forms a "tunnel hole"? It is equivalent to drilling a hole in the wall of the tube.<

/p>

If your family likes to watch spy dramas and suspense dramas, there is a mezzanine on the wall where you can hide silver, etc.

Then this tunnel is a mezzanine in the tube wall, which creates a space. After my gastroscope enters this mezzanine tunnel, the gastroscope can smoothly reach the level of the cardiac sphincter."

"Oh~~~So that's what happened!"
