"What do you think Director Luo is doing?" Director Du asked with a smile.
"Busy for laparoscopy? Or are you outpatient?" Zheng Ren didn't pay attention at all and answered casually.
"I'm learning the ESD surgery you did in the first few days." Director Du said, "We don't do it, and we don't know how good it is, but I heard someone said that Director Luo has organized his doctors who are doing endoscopic surgery to learn it three times."
The surgery performed on old squad leader Fan Tianshui
Zheng Ren smiled. The operation was indeed very good. At least he was satisfied with it.
The system evaluation shows that the degree of completion is 100%. There is no doubt that it is a perfect surgery.
Director Luo's eyes are really bright. The surgery was finally completed with microscopy technology to remove pre-cancerous tumors, which is an area that ESD surgery has not yet touched.
Under normal circumstances, Fan Tianshui's old squad leader would have had to open his abdomen and cut off a section of his intestines to solve the problem.
However, using microscopy technology and minimally invasive resection, the patient recovered very quickly. Damage to the night snack should indeed be taken seriously.
Especially since it is a live broadcast of surgery, I don’t know how many doctors who perform laparoscopy have noticed it.
The two of them came to the endoscopy room, changed clothes and went in.
In the corridor of the endoscopy room, some patients waiting to be diagnosed were sitting quietly. Director Du led Zheng Ren directly to the final demonstration classroom.
"Here is the difficulty of microsurgery." Director Luo wore glasses and looked at the screen seriously.
The door was open. Zheng Ren saw Director Luo's figure and heard his voice, with a smile on his lips.
For senior directors in their fifties, safe retirement is the first priority for many people.
Therefore, exposure to new technologies is basically a matter for younger professors. But looking at the situation in front of him, Director Luo is still very angry, and very high-spirited.
When he was exposed to microsurgery in his fifties, it was unlikely that he would be able to perform it himself.
Whether your eyes are dazzled or whether your hands are trembling are important issues.
It is very likely that Director Luo cannot do it himself, but he must promote this technology.
It seems that there will be fewer gastrointestinal surgeries in the future.
Just as Zheng Ren was about to go in, a nurse ran over.
"Director Luo, there is a small problem with the 8th hand. Please go take a look." The nurse said at the door.
Director Luo nodded and happened to see Zheng Ren.
"Boss Zheng, why are you here?" Director Luo was a little surprised, but then he saw Director Du and immediately knew the reason.
"Is it about the endoscopic jejunal feeding tube?" Director Luo came out and asked.
"Yes." Zheng Ren followed Director Luo to the 8th surgery and said as he walked: "There are not many patients with hyperemesis gravidarum, and there are not many cases of indwelling jejunal feeding tubes until delivery. We can only try to come."
"Is it necessary?" Director Luo still felt that the patient should be given enteral nutrition for a few months for fear of causing problems.
"The patient refused to induce labor no matter what. She was vomiting violently. Even if she survived, I was worried that the baby would have problems." Zheng Rendao.
"Okay." Director Luo agreed simply.
After 8 operations, the patient was under basic anesthesia. A doctor was holding a colonoscope in his hand and looking up at the screen.
On the screen, there should have been a red patch, which was the color of the lining of the colon.
Even if sometimes a small amount of feces remains due to incomplete enema, it is definitely not a lot.
However, the colon lining displayed on the screen in front of me was red and white, which looked very similar to the pattern of watermelon rind.
"Director, please take a look and tell me what's happening?" said the doctor who was doing the colonoscopy.
Director Luo was not very sure, so he pondered for a moment.
"It's a cat-scratch colon," Zheng Ren said in a low voice.
"Huh? Do you have a name? I have seen a few cases and followed them later. There was nothing special after the surgery." Director Luo was very honest.
Zheng Ren only had an impression, because the image looked too typical, so he just blurted it out.
After saying that, he also became silent and went to the system library to browse various materials.
"Boss Zheng, what is a cat-scratch colon?" Director Luo asked.
"It appeared very late. It is still just a theory and has not been clinically confirmed." Zheng Ren smiled and said: "Mell first made a similar description in 2007. Later, 32 of them were found in 9754 colonoscopies. similar cases."
"..." Director Luo was speechless and glanced at Zheng Ren.
"This data was published by doctors in the endoscopic laboratory of Johns Hopkins two years ago. The overall probability of cat-scratch colon appearance should be this high." Zheng Rendao: "Looking at the images, it shouldn't be a big problem."
His eyes were fixed on the screen, entranced.
After all, he is not a doctor in the endoscopy room, so he cannot squat in the endoscopy room every day to perform gastrointestinal endoscopy, so he only saw similar data. This was the first time he observed the true appearance of a cat-scratch colon.
The image of the patient's colon is particularly typical. The colon mucosa is red and surrounded by white linear tears.
It looked like a watermelon rind, so Zheng Ren thought it would be more appropriate to call it a watermelon rind-like change, rather than a cat-scratch colon.
But it doesn't matter anymore.
No matter what the name is, it is a condition.
Of course, it is too arbitrary to say that the disease is a disease. Cat-scratch colon is currently clinically judged not to be a disease at all.
"Boss Zheng?" Director Luo called softly.
"Uh..." Zheng Ren was observing the colon and was woken up by Director Luo. He felt a little embarrassed and said, "It's okay. Cat-scratch colon commonly occurs in the cecum and ascending colon, and is more common in collagenous colitis and diversion colon." inflammation patients.”
"Is it a disease? How to treat it?" Director Luo asked.
"It should not be caused by disease. Most studies believe that barotrauma to the colonic mucosa caused by excessive gas injection during colonoscopy is the main pathogenesis.
Of course, some studies believe that the disease in the intestine itself causes this symptom. "
Zheng Ren explained while admiring the microscopic features of the cat-scratch colon.
"In the vast majority of cases, nothing will happen. In the reported cases, only 1 case of delayed perforation occurred. Because the number is too small, it can be considered that the perforation was caused by other complications rather than excessive air in the colon. Caused.”
"Director, below..." the doctor who was doing the operation asked hesitantly.
"Keep doing it, hurry up." Director Luo said: "Keep the images and send them to my mailbox."
After speaking, Director Luo glanced at Zheng Ren and asked, "Can it be avoided?"
"Probably not." Zheng Ren was also thinking about this issue. "Inflating the colon is done on a high-probability and routine basis. Some patients have colon wall problems that cannot be predicted in advance. In short, just be careful. "
"Yes, you always have to be careful." Director Luo murmured, "We who work in clinical practice must be careful and never be careless."
