"Guess what Director Luo is doing?" Director Du asked with a smile.

"Busy doing laparoscopy? Or are you going out of the clinic?" Zheng Ren didn't care at all and answered casually.

"I'm learning about your ESD surgery for the first few days," said Director Du. "We don't do it, and we don't know where to do it, but I heard that Director Luo has organized his doctors who have laparoscopy to learn it three times."

Which surgery did the old squad leader Fan Tianshui do?

Zheng Ren smiled. The operation was indeed very good, at least he was satisfied.

The systematic review, the completion rate is 100, and it is undoubtedly a perfect level surgery.

Director Luo's eyes were so bright. The surgery was finally completed with microscopic technology to remove precancerous tumors. This is an area that has not been touched by ESD surgery yet.

Under normal circumstances, Fan Tianshui's old squad leader must have an abdominal distension and cut into a section of intestinal tract to solve the problem.

However, using microscopy technology by myself, minimally invasive resection, the patient recovers very quickly, and the injury to midnight snack should indeed be taken seriously.

Especially the live surgery, I don’t know how many doctors who have laparoscopy have noticed it.

The two of them came to the laparoscope room and changed their clothes and went in.

In the corridor of the laparoscopic room, some patients waiting to be treated were quietly sitting. Director Du led Zheng Ren to the final classroom.

"Here, the difficulty of microsurgery lies." Director Luo wore glasses and was serious in front of the screen projection.

The door was open. Zheng Ren saw Director Luo's figure and heard his voice, and a smile appeared on the corner of his mouth.

For the old director in his fifties, safe retirement is the first thing many people need to consider.

Therefore, when exposed to new technologies, it is basically a matter of younger professors leading the group. But judging from the current situation, Director Luo is still very energetic and very high.

When he was in his fifties, he was not likely to be able to perform the microsurgery himself.

Whether your eyes are blurred or your hands are shaking are important issues.

It is very likely that Director Luo can't do it himself, but he also needs to promote this technology.

It seems that gastrointestinal surgery will be a little less in the future.

Just as Zheng Ren was about to go in, a nurse ran over.

"Director Luo, there is a small situation in his hand. You can 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.

"It's for the jejunum nutritional control under the endoscopy." Director Luo walked out and asked.

"Yes." Zheng Ren said as he walked as Director Luo went to his hands: "There are not many patients with hyperemesis gravida, and there are not many cases of indwelling jejunal nutrition tubes until delivery. I can only try it."

"Is it necessary?" Director Luo still felt that he would give the patient enteral nutrition for several months, afraid of problems.

"The patient refused to induce labor no matter what he said, and vomited violently. Even if he survived, I was worried that the child would have problems." Zheng Ren said.

"Okay." Director Luo agreed very simply.

After entering the hand, the patient was under basic anesthesia. A doctor was holding a colonoscopy in his hand and was looking up at the screen.

On the screen, it was supposed to be a red piece, but it was the color of the colonic membrane.

Even if the patient sometimes has incomplete enema and still has a small amount of stool residue, it will definitely not be much.

However, the endometrium of the colon on the screen in front of me was red and white, which looked particularly similar to the pattern of the watermelon peel.

"Director, you take a look. What's the situation?" said the doctor who was undergoing a colonoscopy.

Director Luo was not sure, he pondered for a moment.

"It's a cat's colon, right?" Zheng Ren said in a low voice.

"Hmm? Do you have a name? I have seen a few cases, but I followed them later, and there was nothing special after the operation." Director Luo was very frank.

Zheng Ren just had an impression, because the image was too typical, so he blurted out directly.

After saying that, he also began to remain silent and went to the system library to read various materials.

"Boss Zheng, what is a cat-scratch colon?" Director Luo asked.

"It appeared very late, and it is still just a statement and has not been confirmed in the final clinical practice." Zheng Ren smiled and said, "A similar description was first made by Donnell in 2007. Later, 32 similar cases were found in 9,754 colonoscopy."

"..." Director Luo was speechless and glanced at Zheng Ren.

"This data was published by a doctor in Johns Hopkins' laparoscopy room the previous year. The overall probability of a cat-scratch colon should be so high." Zheng Ren said: "I shouldn't have a big problem when I look at the images."

His eyes were staring at the screen, and he was already immersed in his sight.

After all, I am not a doctor in the laparoscopy room, so I can't squat in the laparoscopy room for gastroenteroscope every day, so I just saw similar data. This is the first time I have observed the real appearance of a cat-scratch colon.

The image in the colon of the patient in front of him is particularly typical. The colon mucosa is red and there is a linear tear white around it.

Looking like watermelon peel, Zheng Ren thought it was appropriate to change the watermelon peel, rather than cat-scratching colon.

But it doesn't matter.

Whatever your name is, it is a disease.

Of course, the condition is too arbitrary, and now clinically determined that cat-scratching colon is not a disease at all.

"Boss Zheng?" Director Luo called softly.

"Uh..." Zheng Ren was watching the colon and was woken up by Director Luo. He was a little embarrassed and said, "It's okay, cat-scratch colon is more common in the cecum and ascending colon, and is more common in patients with collagenic colitis and transfluidic colitis."

"Is it a disease? How to treat it?" Director Luo asked.

"It should not be caused by the disease. Most studies believe that excessive infusion of air during colonoscopy caused by colonoscopy barometric injury is the main pathogenesis.

Of course, there are also studies that believe that the intestinal lesions are caused by the occurrence of this sign."

Zheng Ren explained while admiring the microscopic features of the cat-scratch colon.

"There is nothing wrong with this situation. Only one case reported has late perforation. Because the number is too small, it can be considered that perforation caused by other complications, rather than excessive inflation in the colon."

"Director, below..." the doctor who was doing the operation asked hesitantly.

"Continue to do it and hurry up." Director Luo said: "The image is left and sent to my email."

After saying that, Director Luo glanced at Zheng Ren and asked, "Can it be avoided?"

"It shouldn't be." Zheng Ren was also thinking about this question. "Inflammation in the colon is always routinely given air according to a high probability. Some patients have problems with the colon wall and cannot predict it in advance. In short, just be careful."
