“Can you guess what director Luo is doing?” Department Director du asked with a smile.

“Busy with laparoscopy? Or are you going out for a consultation?” Zheng Ren did not think much of it and answered casually.

“I’m learning about your first few days of surgery,” Chief physician du said,”we don’t do it, and we don’t know what’s good about it. But I heard that Department Director Luo has already organized his subordinates who do laparoscopy to learn it three times.”

The operation for the old monitor, fan Tianshui?

Zheng Ren smiled. The surgery was indeed done well. At the very least, he was satisfied.

The system’s evaluation was that the surgery was 100% complete. Without a doubt, it was a perfect surgery.

Department Director Luo’s eyes lit up. The surgery had finally completed the removal of the early – Stage tumor with microscopic technology, which was a field that had not yet been touched on by the current ESD surgery.

Under normal circumstances, fan Tianshui’s former squad leader would definitely have to open up the abdomen and cut a section of the intestine to solve the problem.

However, he had used microscopic techniques to perform minimally invasive resection, and the patient recovered very quickly with little damage. It should indeed be taken seriously.

This was especially so when the surgery was a live stream. Countless doctors who specialized in endoscopies had noticed it.

The two of them went to the endoscope room, changed, and went in.

There were some patients waiting for treatment sitting quietly in the corridor of the endoscope room. Department Director du led Zheng Ren to the last demonstration room.

“Here, the difficulty of microsurgery.” Department Director Luo was wearing glasses and was very serious in front of the screen.

The door was open. Zheng Ren saw director Luo and smiled when he heard his voice.

For old department directors in their fifties, a safe retirement was the first thing that many of them had to consider.

Therefore, it was basically the younger group professors who were exposed to new technology. However, looking at the situation in front of him, director Luo was still ambitious and very high – spirited.

Since he was in his fifties and had come into contact with microsurgery, the possibility of him being able to personally perform the surgery was not high.

Whether his eyes were blurry or his hands were trembling, these were all important questions.

It was very likely that Department Director Luo could not do it himself, but he would still want to promote this technology.

It seemed like the number of gastrointestinal surgeries would decrease in the future.

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

“Department Director Luo, there’s a small problem with all eight hands. Please go and take a look.” The nurse said at the door.

Department Director Luo nodded and saw Zheng Ren.

“Boss Zheng, what are you doing here?” Department Director Luo was a little surprised, but when he saw Department Director du, he immediately understood the reason.

“It’s because of the endoscopies of the colon nutrient tube, right?” Department Director Luo walked out and asked.

“Yes.” Zheng Ren followed Department Director Luo to do eight rounds. As they walked, he said,””There aren’t many patients with morning sickness, and there aren’t many cases where the colon nutrient tube is detained until delivery. We can only try.”

“Is there a need?” Department Director Luo still felt that if he were to provide the patient with gastrointestinal nutrition for a few months, he was afraid that there would be problems.

“The patient refused to induce labor no matter what. She vomited violently. Even if she could survive, I’m worried that the child will have problems.” Zheng Ren said.

“Alright,” he said. Department Director Luo agreed without hesitation.

After eight surgeries, the patient was under basic anesthesia. A doctor was holding a endoscope and looking at the screen.

The screen was supposed to be red, which was the color of the colon’s membrane.

Even if there were times when the patient’s intestines were not completely filled and there was still a small amount of residual feces, it was definitely not a lot.

However, the colon membrane on the screen in front of him was red and white, which looked very similar to the pattern of watermelon skin.

“Director, please take a look at this. What’s going on?” Said the doctor Who was performing a colonoscopy.

Department Director Luo was not very sure, so he muttered to himself.

“It’s like a cat scratching the colon, right?” Zheng Ren said in a low voice.

“Eh? Does it have a name? I’ve seen a few cases and followed them up. There’s nothing special after the surgery. ” Director Luo was very honest.

Zheng Ren only had an impression of it, but it was too typical from the video, so he blurted it out.

After saying that, he went silent and went to the system library to read all kinds of information.

“Boss Zheng, what is a cat – scratch colon?” Director Luo asked.

“It appeared very late. It’s only a theory now. It hasn’t been confirmed by the clinical trial.” “That’s right.” Zheng Ren smiled and said,”in 2007, it was McDonnell who first made a similar description. After that, we found 32 similar cases in 9754 colonoscopies. ”

“…” Director Luo was speechless. He glanced at Zheng Ren.

“This data was published by a doctor from John Hopkins’s laparoscope two years ago. The probability of an overall occurrence of a cat – scratch colon should be this high.” “I’ve seen the image, it shouldn’t be a big problem,”Zheng Ren said.

His eyes were glued to the screen, completely absorbed in it.

After all, doctors who were not in the laparoscope room could not squat in the laparoscope room and perform Gastroenterology every day, so they only saw similar data. This was the first time they observed the true appearance of a colon that looked like a cat’s scratch.

The image of the patient’s colon was particularly typical. The colon mucous membrane was red, and there were white lacerations around it.

It looked like a watermelon skin, but Zheng Ren felt that it was more appropriate to call it a watermelon skin – like change instead of a cat – scratching colon.

But it didn’t matter.

Whatever the name was, it was a kind of illness.

Of course, it was still too arbitrary to say that it was a disease. The clinical diagnosis of cat – scratch colon was not a disease at all.

“Boss Zheng?” Director Luo called out softly.

“Er …” Zheng Ren was observing the colon. He was a little embarrassed when he was woken up by Department Director Luo. “It’s okay. Cat – scratch colon usually occurs in the cecum and ascending colon. It’s more common in patients with collagonizing enterojeonies and circulative enterojeonies. ”

“Is it an illness? How do we treat him?” Director Luo asked.

“I don’t think it’s caused by a disease. Most studies believe that the main mechanism is that air pressure is caused by excessive gas injection during colonoscopy.

Of course, there are also studies that believe that it’s caused by pathological changes in the intestine. ”

Zheng Ren explained as he enjoyed the cat – scratching feature of the colonoscopy.

“In most of these situations, nothing will happen. Among the reported medical cases, only one patient had delayed perforation. Since the number is too small, we can assume that the perforation was caused by other complications and not caused by excessive inflation of the colon. ”

“Department Director, what’s next …” The doctor Who was operating on the patient asked hesitantly.

“Continue. Make the best use of your time.” “Keep the video and send it to my email,” director Luo said.

Director Luo glanced at Zheng Ren and asked,””Can it be avoided?”

“I don’t think so.” Zheng Ren was also thinking about this problem.”Pumping air into the colon is done according to the high probability and the standard procedure. Some patients have problems with the colon wall, and it can’t be predicted in advance. Anyway, just be careful. ”

“Yeah, we have to be careful.” Department Director Luo mumbled,”we clinical doctors have to be more careful. We can’t be careless.”
