Professor Liu was overjoyed. At the same time, Zheng Ren's mobile phone rang.

"President Wang." Zheng Ren connected and said hello.

"Oh, OK, I'll have a look."

With that, Zheng Ren hung up the phone.

"Boss, come back so busy." Gao Shaojie said with a smile, but also some regrets. Boss Zheng is too busy. It seems that it is very difficult to do teaching surgery.

"If a general foreigner has a problem, go up to Mr. Wang and have a look. Didn't he call?" Zheng Ren said with a smile, "director Zhou, I'll take a look in the operating room."

"Well, you're busy, you're busy." Director Zhou also received a call from President Xiao, ready to explain immediately and leave in a hurry.

It's not appropriate for Gao Shaojie, Professor Liu and Wang Qiang to follow in the operating room. They are going to discuss and catch Zheng Ren. No one wants to let him go.

Zheng Ren doesn't care. It's not a big deal to have an operation if it's convenient. He reported his itinerary to Xiaoyi and rushed all the way to the operating room.

President Wang waited for Zheng Ren in the dressing room. When he saw Zheng Ren coming, he said, "boss Zheng, director Sun has something to do. Consult on the stage."

"What patient?"

"The preoperative consideration is gastric cancer and resection is necessary. But after opening, the situation is wrong, and director Sun is also cautious."

Thinking of director Sun, Zheng Ren smiled.

I don't know whether his little grandson has recovered well. Director Sun has been cautious all his life. To tell the truth, he is really not expected to be a big director. With Liu Tianxing, general surgery can hold up. It is reasonable that Liu Tianxing's general surgery business shrank due to his illness.

It's not how bad director Sun's operation level is. He's just timid.

I want to retire smoothly without causing any trouble.

But in surgery, the heart is separated from the belly. Who can guarantee that it will open as expected? If Wang could always stay in Haicheng, he would be the director of general surgery in three years.

But he's a 912, and he won't stay.

"Gastric cancer, is the adhesion too heavy?" Zheng Ren asked.

President Wang shook his head, indicating that he didn't know. They changed their clothes and went in with hats and masks.

Opening the airtight door of the operating room, director Sun stood in the position of the operator, with his back to the airtight door. He didn't see them for the first time. The assistant is the general manager of the second Department of general surgery. As soon as he looked up and wanted to say hello, he was stunned when he saw a familiar face.

"Is president Wang here? Give me a slap and see what it is." Director Sun looked up when he saw the inpatient in the first aid position. He didn't look back and said directly.

Director Sun's speech is very polite and familiar. It seems that he has no less trouble with President Wang at ordinary times.

"Zheng..." said the hospital manager in amazement.

"What? It's an operation. You always look for Wang. You can't talk." Director Sun scolded.

"Director, it's president Zheng." Hospital summary stuttered.

Director Sun's hand was slightly stiff and asked in surprise, "who?"

As he spoke, he looked back.

Between Zheng Ren's mask and hat, smiling eyes appeared in front of him. Gentle and honest.

Sure enough, it's Zheng Ren!

"Ah, Mr. Zheng, when did you come back?" Director Sun immediately said happily.

"I arrived in the early morning. Come back and see the old director." Zheng Rendao.

Of course, director Sun knows that the old director refers to Director Pan, not himself, let alone Liu Tianxing.

"Just right, just right, President Zheng and President Wang, give me a hand." Director Sun didn't forget about the operation. Zheng Ren was there. It was the best, he said quickly.

"The patient is a 66 year old male patient. The physical examination found a tumor on the gastric wall. It is considered to be gastric cancer. The outpatient department is admitted to the hospital. There are no surgical contraindications. This is why he came to the stage." Director Sun briefly introduced the medical history: "President Zheng, why don't I look like gastric cancer?"

Zheng Ren stood behind director Sun and looked.

The adhesion in the abdominal cavity is very heavy. I don't know how long the operation took. It's free and messy. However, the tumor near the stomach wall has exposed its head and is dripping with blood.

"Has the patient had surgery before? What is the past history?" Zheng Ren asked.

Generally, such severe adhesion is caused by previous surgery or trauma.

Otherwise it wouldn't be so heavy.

"The patient's private history, no surgery, and no history of major trauma." The general hospital will report immediately.

"Huh?" Zheng Ren pushed forward again and took a look at the patient's systematic diagnosis.

Systematic diagnosis has nothing to do with gastric cancer, but it is a disease of gallbladder - old gallbladder rupture.

What the hell is this? Zheng Ren thought for a moment and said, "director Sun, go up and look at the gallbladder area."

The patient's private prosecution can only be used as a reference. Sometimes patients themselves will ignore many situations, which is very common in clinic.

It is said that there is no major trauma, and the credibility of this private prosecution is absolutely no more than 10%. (Note 1)

Director Sun was stunned for a moment, looked at the sticky mess of the abdominal cavity, and carefully asked, "President Zheng, President Wang, why don't you give me a hand?"

Zheng Ren smiled, nodded and said, "the operation is difficult. Can I let Yi go?"

Director Sun naturally won't object. It's just a moment. It's nothing.

Zheng Ren's hands are itchy. He disinfected the surgical instruments early in the morning and hasn't been used yet. This difficult operation happens to use the instrument given to him by Dr. Charles.

"Yi Ren, there is an operation in the operating room. Come and give me a hand and bring the surgical instruments by the way." Zheng Ren made a phone call to Xie Yiren and began to brush hands with President Wang.

"Boss Zheng, what do you suspect?" While brushing his hands, President Wang asked.

"The patient's abdominal adhesion is too heavy. There is no doubt. It needs to be free and explored. But it doesn't look like gastric cancer. Let's talk about it." Zheng Ren also doubts the diagnosis of big pig hoof.

When something grows on the stomach, the big pig's hoof tells itself that it is gallbladder disease. Isn't this bullshit? However, Zheng Ren's trust in big pig hoof is still very high. He has no simple doubt, but decides to have a look.

President Wang deeply thought of Zheng Ren's answer, and he thought so.

Such a heavy adhesion, if the operation is ruled out, the patient has suffered trauma.

First explore and check. Take a frozen pathology during the operation, and you can confirm it with a high probability.

After brushing his hands and putting on his clothes, the general manager of the second Department of general surgery directly stepped aside. Director Sun also stood in the second help's place and waited for Zheng Ren to come up.

I haven't seen president Zheng perform surgery for a long time. If President Zheng doesn't go, I don't have to be so frightened. Director Sun sighs.

Note 1: many patients found old rib fractures. They didn't pay attention to the fracture at that time, thinking it was contusion.

This kind of thing is very common.
