Takahashi's speech received a round of warm applause, and those wonderful drawings were also constantly praised.

"Dr. Takahashi, in your surgery, after reconstructing the anus, the nerve reflex controlled by the muscles is the opposite of the natural anal sphincter, the anal sphincter usually contracts and closes, and only relaxes and opens during defecation, and the pectoralis minor muscles you take are usually in a relaxed state, and they will contract when you exert force." A graduate student asked.

The people who can ask questions are the ones who usually study hard, otherwise their heads will be full of paste at this time, and where will they ask questions.

"You lack a minimum knowledge of reconstructive surgery-" As soon as the words came out, Takahashi immediately realized that his tone was wrong, and turned his head to look at Yang Ping, who had no abnormality on his face.

He confirmed that Yang Ping didn't notice the tone of his delineation just now, paused, and continued, but his tone had been suppressed: "After surgery, biofeedback stimulation is used to rebuild the coordination of transplanted muscle contraction, that is, we train the muscle to keep it contracted and closed at ordinary times, and diastolic when needed. ”

"The expulsion of stool is not only the opening of the anus, but also the rhythm of the rectum that contracts and peristalsis to push the stool down until it is discharged, and the patient's rectum and sigmoid colon are defective, how to solve this problem?" There are PhDs who ask more pointed questions.

Academic arguments, the six relatives don't recognize, whoever is reasonable is the boss, these guys are usually immersed in technical research, and they don't have the sleek sophistication of social people.

"This problem does not exist, the whole intestine has the ability to move and propulse, and the descending colon is no exception, although the descending colon does not have a strong thrust of the lower rectum, but given the principle of adaptation of human anatomy and function, with the increase in the number of uses of the reconstructed anus, the thrust of the descending colon will gradually increase to adapt to its work position."

"You just mentioned that the sphincter is taken from the pectoralis minor muscle, and you didn't mention where the material for urethral reconstruction comes from? I would love to know what materials you plan to use for the reconstruction of the urethra? Anterior or posterior bladder wall? The deputy chief physician of the Department of Urology asked.

He has also done urethral reconstruction, so he is naturally concerned about this aspect, Yu Shuilian is almost the entire urethra is missing, such a long distance, what material is the best to use, if you use the bladder wall mucosa to rebuild, I am afraid it is not enough.

"The urethra can be reconstructed using the colonic mucosa, so that the material is sufficient, and there is no limit to the length of the urethra.

Urethral reconstruction is a field of urology, but Takahashi is a compound trauma surgeon whose level is not inferior to that of any urology hospital in the world.

There are many questions, from graduate students who have just debuted to doctors with high professional titles in their specialty, and Takahashi relies on his extensive and profound knowledge to handle every problem perfectly.

Usually at international academic conferences, Takahashi is known for his aggressiveness, and once singled out a few Yankees at a trauma surgery conference in North America, making people speechless.

Today, I was too excited for a while, and I almost fell off the line, but fortunately, I stopped it in time and did not cause serious consequences.

Of course, this serious consequence is also what Takahashi himself thinks.

The contradictory mood of nervousness and self-confidence is intertwined, because Yang Ping is sitting under the podium, so he is nervous, and the student's mentality makes him always have to take care of Yang Ping's expression, for fear that he will not perform well.

Confidence is in the face of the audience, he is used to talking highly, self-confidence flying, and it is inevitable to go off the line when he is excited.

When it was Song Zimo's turn, the surgical atlas he showed was actually more beautiful than Gao Qiao, probably influenced by Professor Zhang, Yang Ping's guidance, his surgical atlas has a strong three-dimensional sense, and the visual effect of Gao Qiao's flat graphics is definitely a few points better.

Takahashi's surgical design has been very perfect, many things overlap, the same place, he just briefly went through it, focusing on what Takahashi did not say.

"The patient's ovaries, fallopian tubes and uterus have been preserved, and I can't just focus on the reconstruction of the urethra and anus, I should consider reconstructing YingDao to address the problem of periodic endometrial collapse and the discharge of the accompanying bleeding in female patients."

"The patient has given birth, and in this particular case, the uterus is no longer meaningful, so why can't the uterus be removed? This eliminates the need to rebuild the YD and reduces the hassle. "A newly recruited doctor from the Department of Trauma and Orthopedics proposed a simpler method.

It can be excised, but why reconstruction? Bring sand to the beach! The logic of the questioner is clear.

"Hysterectomy not only leads to the inability to get pregnant normally, but also may cause ovarian function decline, estrogen secretion disorders, abnormal blood lipid metabolism, etc., endocrine abnormalities may affect the mental and psychological aspects, and it is not excluded that it can lead to depression."

"We are troublesome for a lifetime."

Song Zimo's thinking is just the opposite, it can be reconstructed, why excision.

It can be ninety, why am I only staring at sixty.

The discussion between the top students makes ordinary students naturally marginalized, which is a reality that cannot be changed.

The discussion made Song Zimo and Takahashi the protagonists, and even Xu Zhiliang of the trio was under a lot of pressure.

If clinical experience is seen as card power, and personal IQ is card skill, this discussion is like playing cards.

When the cards are evenly matched, the technology can be useful, the card power is seriously tilted, and any technology can not affect the outcome.

Gao Qiao's hand is the best, Song Zimo's card skills are the best, Xu Zhiliang does not have an advantage, there is a gap between card skills and Song Zimo, and the card power is far from Gao Qiao.

But he was not discouraged, on the contrary, he was high-spirited, happy that he could enter such a team, and grateful to Yang Ping for not disliking his birth defects and giving him a precious opportunity.

Gao Yuan, director of the sports medicine center, was too busy, just finished dealing with the matter at hand, and hurried over, the comprehensive orthopedic meeting, case discussion, preoperative discussion, small lectures, as long as he was free, he definitely wanted to participate.

When Director Gao arrived, the conference room was already crowded, with a rectangular conference table with rounded corners in the middle, surrounding the conference room, keeping a distance of one meter, with three floors inside and three floors outside, and even the door was crowded with people.

How to get in, Director Gao didn't care about his identity, he had to squeeze in, he turned his body sideways, used his brute strength, and squeezed it in, an intern, his eyes were staring at the electronic screen, and his ears were listening vertically, at this time, damn it, a person was always squeezing around.

Angry for a while, the intern didn't even look at it, his body slammed into the direction where the squeezing force came from, and Director Gao was knocked backwards and almost fell.

"Squeeze your head, it's full early, don't come early." The intern cursed under his breath, but his eyes were still fixed on the screen.

Director Gao barely stood firm, wiped his sweat, everyone listened attentively to the speech inside, and no one paid attention to him.

Lao Gao didn't care about this intern, there were two doors in the conference room, which couldn't be squeezed in one side, and the other side was similar, airtight.

There was no way, Lao Gao asked the nurse for a chair in the ward, put it at the door, found a paper cushion, and stood on the chair, so that he could see inside.

Fortunately, everyone is more disciplined, except for the speaker, no one else spoke, even if he whispered a few words, he could hear it clearly, it was already Song Zimo speaking.

Yang Ping should not have spoken yet, he should be the last to speak, Director Gao is glad that he is not too late.

When Takahashi heard Song Zimo's YD reconstruction, he couldn't help but feel ashamed, and he really didn't think about it so thoroughly.

Song Zimo really deserves to be Dr. Yang's assistant, and his consideration for this patient's surgery is even deeper than his own.

Xu Zhiliang's surgical plan could no longer surpass Gao Qiao, and after he stepped onto the stage, Zhang Lin subconsciously trembled in his heart.

Seeing Xu Zhiliang speak, Zhang Lin was anxious, but Lao Xu really didn't stutter when discussing the case: "The surgical plan, the front has been very perfect, I only have one immature suggestion, after the patient loses the lower half, he loses his sexual characteristics, can the shape of WaiYin be reconstructed from the patient's psychological considerations, which is more acceptable than the abrupt pore appearance, and at the same time, the natural WY structure of women can protect the urethral opening and reduce the possibility of urinary tract infection." ”

Xu Zhiliang's suggestion was not necessary, and even for most doctors, they would not consider this issue at all, but Xu Zhiliang considered it and bravely put it forward.

There was another discussion, some people around us asked questions, and some people from the comprehensive orthopedics department themselves argued with each other, and finally, it was Yang Ping's turn to speak.

Everyone is looking forward to the stars and the moon, and the climax of the meeting is now, especially Lao Gao, standing with numb legs, just for this moment.

Yang Ping stood on the podium, and dozens of mobile phones were secretly pointed at him, and his memory was not as good as the mobile phone video.

More than a dozen pictures go through it first, what kind of meeting, it's enough to look at these pictures, I don't know and think that the black and white camera takes photos of the human body, and the key photos will not be so three-dimensional.

These pictures also borrow the storyboard technique of comics to show the steps of the operation clearly, and there are close-up magnified shots of the key steps.

He summarized everyone's plan a little, and then added his own opinion: "Reconstruction of defecation function, in addition to rebuilding the sphincter, also needs to carry out bladder mucosal transplantation, move part of the bladder mucosa to the inner surface of the descending colon, and there are baroreceptors in the bladder mucosa, and use these baroreceptors to reconstruct the intention of defecation and establish a real voluntary defecation function." ”

To transplant the bladder mucosa, it is necessary to connect the nerves, and the dissection of the nameless small nerves is difficult to do, otherwise many surgeons will do this.

Mucosal transplantation, if the connecting nerves are not considered, the baroreceptors cannot transmit signals to the centers of the brain and spinal cord, as if they were not present.

If you can find the unnamed neural connection and then use biofeedback training, recovery is perfectly feasible.

However, finding the innominous nerve of the bladder mucosa and having a length that can connect the pudendal nerve and its branches is something that surgery simply cannot do.

Takahashi once did research in this area, but it ended in failure.

Many top urologists and reconstructive surgeons in the world have also tried, but they have all failed.

This is destined to be an unachievable operation that can only exist in theory.
