After binding with the system, I became a proctology expert.

Among these surgical methods, the Z-shaped suture technique is more suitable for patients with small and superficial lesions.

Not suitable, PASS.

Bascom hip lift is also not suitable, PASS.

……

After much deliberation, Lu Renxin felt that the most suitable procedure for this patient was the Limberg flap transfer.

This surgical technique is not only classic and widely used, but it can also achieve tension-free closure, making it suitable for his large-area lesions.

Although the surgery is a bit complicated, with the teacher's skills, there shouldn't be any problems.

He stopped hesitating and directly stated his thoughts: "I think he can use a rhomboid flap transfer technique."

Zhang Weimin looked pleasantly surprised. His eyelids, which were slightly droopy due to his age, were forcibly lifted, and an appreciative smile appeared on his face.

"Hmm, not bad. It seems you study in your spare time and have some understanding of today's cutting-edge technologies."

"I thought you were going to tell me about the two surgical methods I usually use."

Lu Renxin chuckled twice, then didn't say much more, appearing exceptionally humble and unassuming.

He did study it in private, but he really didn't know much about pilofibrils.

If I hadn't seen it yesterday, I might not have been able to answer it and would have embarrassed myself in front of my professor.

Zhang Weimin began the procedure. This surgical method was challenging, requiring the use of a rhomboid defect as a base and the transfer of an adjacent rotational flap to repair the wound.

This was the first time Lu Renxin had ever seen it, and he stared intently, afraid of missing any key points of the operation.

Zhang Weimin then removed the lesion.

"Make it into a standard diamond-shaped wound," he reminded Lu Renxin as he worked.

Then, design a triangular flap with equal length and width on one side of the rhombus.

Zhang Weimin carefully made a subcutaneous incision in the skin and bluntly dissected it with hemostats to form a skin flap.

"Then we rotate it to the defect area and perform tension-free alignment suturing." Zhang Weimin pulled the flap open to show Lu Renxin.

[Congratulations, host, on completing surgery*1. Healing value +8]

The healing value has increased again. This is the joy of performing surgery with a mentor. There are more opportunities to participate and have hands-on experience.

[Congratulations, host, on completing surgery*1. Healing value +6]

[Congratulations, host, on completing surgery*1. Healing value +6]

……

The eight surgeries took a total of more than five hours.

The morning session ended perfectly, and Lu Renxin reaped a great harvest, gaining a total of 52 healing points.

After the procedure, he changed his clothes and left the operating room. Before leaving, he said goodbye to the aunt and hoped that he could wear a surgical gown without holes next time.

He didn't go back to his office, but instead went to the ward first.

The patients have all returned, and we need to conduct post-operative rounds, instruct them on precautions, and explain their conditions.

Bai Zongbao, the first patient to undergo surgery for pilonidal sinus, has fully recovered from anesthesia.

He was lying in bed, groaning and complaining of pain.

Beside him was his mother, who had come to keep him company. She was sitting on the edge of the bed with a white towel in her hand, wiping the cold sweat from his forehead with loving eyes.

Lu Renxin's arrival shattered the quiet warmth and harmony between mother and son in the ward.

"Bai Zongbao?"

"Uh, doctor, I'm here," Bai Zongbao replied weakly.

Lu Renxin didn't waste any words. He spoke clearly and explained his surgical procedure in the simplest and most understandable language possible.

"You also need to pay attention to two things. One is to remove the hair around the area after you go back, otherwise it will grow into the flesh and recur."

Upon hearing that the condition might relapse, Bai Zongbao, who had already suffered from it, nodded repeatedly, wishing he could transform into a white-cut chicken and pluck all the feathers off his body.

Suddenly remembering something, she asked, "Doctor, should I use wax, laser, or a razor?"

You seem to know quite a bit about hair removal.

"Anything is fine, as long as you're clean."

You can even pluck them off one by one with tweezers.

"There's one more thing," Lu Renxin paused, "You need to lose some weight."

lose weight?

Bai Zongbao's face was full of reluctance: "Ah, is my illness related to dieting?"

Lu Renxin patiently explained, "Of course there is."

Obesity can deepen the skin folds in the buttocks area, making it more prone to sweating and dampness.

It can also increase internal pressure and friction, making it easier for hair to penetrate the skin.

He continued to explain: "Actively controlling your weight can reduce pressure on the sacrococcygeal region and prevent recurrent pilonidal sinus attacks."

Bai Zongbao's chubby, round face was full of reluctance: "Alright then, I'll try my best."

It sounds like a perfunctory excuse; he simply can't let go of steamed lamb, steamed bear's paw, steamed deer tail, roast duck, roast chicken, roast goose...

Mrs. Bai had just gone to the bathroom to wash the towels. When she returned, she happened to overhear Lu Renxin mentioning the downsides of obesity. She wholeheartedly agreed and chimed in:

"I told you to lose weight, but you absolutely refused to listen, making it seem like I was trying to harm you. Look at the suffering you're going through now..."

Once she started talking, she couldn't stop, nagging about how her son was greedy, lazy, and couldn't control his eating habits at home.

Bai Zongbao's face grew increasingly red, his expression a mixture of shame and indignation: "Stop talking."

"Why have I never tried to lose weight? Every time I tell you to eat less, you cook big, meaty meals and say that you can't just starve yourself to lose weight."

"They always deliberately put my favorite braised pork in front of me. Do you think I can ever lose weight?"

"I was just worried about you, wasn't I?" Mrs. Bai looked a little guilty, but quickly regained her composure:

"It's not good to starve yourself, you can just exercise more, right?"

Parents everywhere feel the same way: they both dislike and can't bear to let their children suffer.

You want him to lose weight, but you don't want him to go hungry. There's no perfect solution.

After seeing all the patients, Lu Renxin was about to return to his office when he heard a man's angry voice before he even entered the door:

"I don't care, you'll have to deal with the mess you made."

"How could you make a mistake doing something as simple as eating?"

The voice sounded very familiar, like Wang Jingyao. Had he eaten gunpowder?

Pushing open the door, I saw a short, thin figure from behind; it was indeed him.

There was another person standing vaguely opposite, enduring his rage.

But when Lu Renxin saw who it was, he couldn't help but frown.

How could it be Tian Jingjing?

Tian Jingjing was looking down with a wronged expression, tears welling up in her eyes.

Faced with Wang Jingyao's reprimand, he kept his lips tightly pressed together and didn't say a word.

Lu Renxin quickly stepped forward and stood between the two: "What's going on? Don't get angry at the new intern. Can't you talk things out?"

Wang Jingyao raised his voice: "What are you pretending to be a good person for? Ask her, she can even prescribe the wrong medicine for bed 60."

"Do you know who's in bed 60?"

Bed 60 is a VIP ward in the proctology department, the only single room available. It's expensive, costing 1200 yuan per day, and it's a completely out-of-pocket bed that isn't reimbursed.

Lu Renxin seemed to have heard someone mention that one of He Ping's associates was staying in that ward, apparently a leader from some place.

But this has nothing to do with him.
