Chapter 643

"Ah." Zheng Renye sighed.

"Not bad." Su Yun interjected: "During my obstetrics internship, I met a little girl who came for an abortion every two months. You guys guess, why?"

"It couldn't be for weight loss, could it?" Zheng Ren exclaimed.

"Exactly." Su Yun drained the cup in front of her, saying: "My Title: Teacher advised her several times, but it had no effect. Actually, I still can't understand why, for weight loss, one would pay such a price."

"Kids don't understand." Lin JiaoJiao said: "They just think about eating and drinking well, yet not getting fat. How many people can have such luck?"

Zheng Ren suddenly recalled that Xie Yiren could eat and drink but didn't gain weight... In an instant, he felt especially deeply about the phrase "those who don't get fat from eating have nothing to fear."

"Zheng Lao Ban, that child three months post-op indeed lost over twenty pounds. But a few days ago, she had dark tea-colored urine and generalized jaundice. I admitted her to the hospital and performed percutaneous biliary drainage; now her symptoms aren't that severe, her life is saved. Yet ultrasound and CT showed nothing abnormal."

"What are you considering?" Zheng Ren asked simply.

This is Di Du; the hospital Lin JiaoJiao took the patient to is likely 912 Hospital, a top-tier national tertiary hospital.

It differs essentially from Hai Cheng.

"For now, we haven't considered anything else; we're preparing to do an ERCP, use the scope to confirm diagnosis, then proceed with next-step treatment." Lin JiaoJiao said: "This is perfect timing for you to come back and let you take a look."

"The films are here, right?" Zheng Ren asked.

"Yes, I had someone fetch them when I arrived." Lin JiaoJiao nodded; her assistant went out and soon returned with someone.

She held the films, followed by two staff members carrying a viewbox.

"Zheng Lao Ban, please take a look." Lin JiaoJiao stood, took the film bag from the assistant, and approached the viewbox.

Zheng Ren smiled: "Sister Lin, you're too kind."

Taking the film from Lin JiaoJiao's hand, he placed it on the viewbox, left hand under his right armpit, right hand supporting his chin, and examined it seriously.

Although he was already tired, once he stood at the viewbox and began reading the films, Zheng Ren instantly felt energized.

The professor wiped his mouth with a napkin, also came to Zheng Ren's side, while Su Yun held her phone, not even glancing at the films.

"Boss, is this speck an artifact or something real?" the professor pointed at a tiny dot and said.

"Only CT, really hard to tell," Zheng Ren also hesitated.

Many patients' conditions cannot be fully determined from a single CT film.

Experienced doctors can likely judge based on the patient's actual condition, but to claim 100% certainty without pathology, who dares?

"Here the density resolution is poor, spatial resolution also has issues; try increasing the energy of the electron beam from the gun by an Enhancement, see if it becomes clearer?" Zheng Ren rested his chin on his hand, speaking words Lin JiaoJiao didn't understand at all.

Not to mention Lin JiaoJiao; even Director Kong, a veteran imaging specialist, doesn't understand what Zheng Ren is saying.

The principle of CT is that the electron gun produces an electron beam aimed at a ring-shaped tungsten target; detectors arranged in a ring collect the information. But increasing the energy by a gradient?

The professor doesn't fully understand either, but having experience with TIPS Surgery research, he can roughly grasp Zheng Ren's meaning.

Su Yun played with her phone, mouth twitching, revealing a hint of mocking smile, thinking, "This guy is showing off again."

But he has the confidence; you could say he's bluffing, yet he always finds a way to solve the problem, so Su Yun, even if she wanted to retort, couldn't.

He mentally calculated according to Zheng Ren's words, his brow furrowing.

Looking up at the film, Zheng Ren's finger happened to point at a spot.

"If the energy is increased by a gradient, looking at density there, it should be an ulcer," Su Yun said.

"Hmm, the periphery is an ulcer, but beneath it there is a high-density substance; considering it might be a small solid tumor, exactly what it is requires pathology to determine." Zheng Ren pressed his finger firmly on the film, stating definitively.

"..." Su Yun felt her work was flawless; how could Zheng Ren still see more?

Director Kong was stunned, his mind in chaos; after just a moment's thought, he felt his whole brain heat up and his vision slightly dizzy.

Zheng Ren's principle, Director Kong understands. But if relying on mental calculation, given his age, he could never reach that level.

Not only him, Professor Rudolf Wagner was stunned for a while, then hesitantly said: "Boss, is this speck it?"

"Hmm. Ulcer at the duodenal anastomosis, issues around the ampulla and pancreatic head." Zheng Ren said, "Sister Lin, hurry up and do an ERCP, use the scope to look. Also, tell the doctor to perform intraoperative frozen section."

Lin JiaoJiao hadn't expected Zheng Ren to solve it; she just wanted to avoid embarrassment at the table and didn't know what to say.

For someone like Zheng Ren, a surgery addict, having him eat and stay in the Operating Room is happier than eating delicacies at a club. Even without surgery, just being able to view a film is a hundred times better than sitting idle chatting.

But she never expected that Zheng Ren would actually give such an accurate diagnosis.

Lin JiaoJiao felt somewhat bewildered, and instinctively turned her head to look at Director Kong.

"According to Zheng Lao Ban, when should we do the ERCP?" Director Kong asked.

"It's scheduled for the day after tomorrow." Lin JiaoJiao said.

"I'll call Old Shi and have it done tomorrow." Director Kong then asked for the patient's name and dialed the phone.

"Old Shi, it's me, Old Kong."

"There's a young patient; I just looked at the images on my side and suspect there might be a serious problem. Please arrange an ERCP for tomorrow."

"We can't delay; the patient is young, and I'm worried something serious could happen."

"Alright, then you can finish work at noon. Good, I'll treat you to drinks another day. By the way, prepare the intraoperative frozen section—don't forget."

Having said that, Director Kong hung up the phone.

Xie Yiren blinked her big eyes at the scene before her, a smile in her gaze.

Seeing Zheng Ren's confident statement, Lin JiaoJiao felt a bit anxious. She had originally just wanted to go through the motions, and incidentally let Zheng Ren take a quick look… but this 'quick look' wasn't really meant to have him uncover any problems.

Only the parties involved can truly sense the subtle differences.

At this point, even eating had lost its flavor. Lin JiaoJiao had something on her mind; seeing that Zheng Ren and the others were also tired, after another twenty minutes she began to organize their dispersal.

Chang Yue was holding her phone, engrossed in what she was watching. Xie Yiren went to call her, noticing she had muted the volume and was watching an animated series…

"Impressive." Su Yun said coldly from behind.

"What do you know." Chang Yue's voice was even more aloof, "Drinking with you guys is boring; if not watching cartoons, what else can we do?"

Just that sentence, and Su Yun's battery ran out…
