"For patients like this, we should have three levels of expansion. Take it slow, and upgrade if the pressure at the first step is not enough," Director Guan explained to him.

Shao Jialiang believed what Director Guan said. The last time the patient had an endoscopic surgery in their hospital, Director Guan was present. He knew very well that the patient's body tissues were weak and prone to bleeding. If the pressure was too high, it might not have a therapeutic effect but would cause secondary damage to the body.

Now the operator adds the maximum pressure at once, I am afraid that the novice does not know much and is too bold. It is like some reckless novice drivers who only press the accelerator to the bottom.

What is puzzling is that Xie Wanying was so slow in placing the guide wire before, but now it is suddenly so fast that it is almost fatal?

Yu Xuexian remained silent. Shao Jialiang did not dare to speak out after his mistake. He waited for the follow-up with a roller coaster-like mood. Anyway, after the balloon dilation, we can basically know whether the fistula can be found.

On the screen, the stretched anastomosis looked like a big black hole. Others looked for the small black hole, which was the location of the fistula.

"Here." The nurse who was closest to the monitor connected to the gastroscope shouted.

Everyone immediately rushed to the monitor to check as if they had heard the news of the discovery of a new continent.

"Where, where?"

...

...

People were crowded together, everyone stretched their necks and opened their eyes wide.

"Here." The nurse pointed to the spot on the screen.

The others calmed down and followed the surgeon to adjust the angle of the gastroscope inside the patient's body. The screen was like unveiling the last layer of mystery, and gradually, a fistula appeared more and more clearly in everyone's vision.

Director Guan, an expert, was the first to be speechless. He was a little confused. He had previously questioned whether the other party would be able to achieve the desired result in one step under the maximum pressure, but the result was - this?

How could an intern do something that he, an expert, couldn't do? He was speechless.

He was wrong. He was not too slow or too fast, nor was he guilty of lack of confidence or reckless of complacency. He was just very clear-minded and methodical, just like an old doctor.

It seems that this student has more than just a strong mentality to keep calm. For a doctor to keep calm, how can it be possible without skills?

Director Guan's eyes snapped and locked onto Xie Wanying's face. He might remember such a student for the rest of his life. Because it is not easy to meet such a talent in a doctor's career, too many are mediocre.

Turning around, Director Guan glanced at Yu Xuexian again.

Yu Xuexian raised the corner of his mouth, as if he had known this result.

Director Guan sighed in his heart: These new technically skilled doctors in the National Association are very capable, and they have a thorough understanding of their students and electronic gastroscopy. Otherwise, how could they dare to let go so easily and finally wait for such a good result.

If a teacher does not have a deep understanding of the technology, he or she will not dare to let the students do it. This is a clear truth. As a teacher, you must provide a backup for the students' operations. If anything goes wrong, the teacher is responsible, not the student.

At the same time, the students' trust in the teacher is also very important. Xie Wanying was seen doing it wholeheartedly without fear, all based on her trust in Brother Yu who was behind her.

Xie Wanying knew how capable Senior Brother Yu was. Before Senior Brother Yu asked her to do it, he had already guessed the reason why Dr. Xuan Wu had failed the first time.

It was easy for Yu Xuexian to guess the reasons for his peers' failure.

The director did not clamp the important fistula accurately, which showed that the balloon expansion was not in place, so the exact location of the fistula could not be found from the endoscopic perspective.

Why didn't the doctor find the right spot? Was it because the previous doctor's eyesight was not good enough? As a technical expert in this field, he must understand the deeper logic behind it. Because the first sentence of the patient's attending doctor emphasized the patient's physical condition. The patient's wound is prone to poor healing, and the tissues in the body are either constantly ulcerating and bleeding, or constantly proliferating and stiffening. The tolerance of the patient's tissues is too low, and even a small large-scale operation may cause perforation.
