Chapter 484

Chrysanthemum, there are many poems about chrysanthemum, but in modern times, the more famous one is this one: when autumn comes, September 8, I will kill hundreds of flowers after my flowers bloom. The sky fragrance array penetrates Chang'an, and the city is full of golden armor.

Moreover, I don't know which great God compared the anus with chrysanthemum. The great God is very cow, and his description and metaphor of anus are very in place. It's not in the medical field. It's estimated that it's also specialized in Chrysanthemum and anus related majors.

Otherwise, ordinary people can never describe such an appropriate metaphor. Why describe chrysanthemum as anus, not Lily or trumpet?

There is a reason for this. There are two forms of flowers on the inflorescence of chrysanthemum. One of them is the simple chrysanthemum, commonly known as the "flower center". The Corolla is connected into a simple shape. It is a bisexual flower. There is a pistil in the center, the stigma is 2-lobed, the ovary is 1 room below, and there are 5 drug stamens around the main flower.

It's this kind of flower. It's like an anus. Especially with the tight anus.

Anus, complex structure. It is about 4cm long. When it is derived from the rectum to the anus, it begins to thicken, just like the lips. And a vertical anal column.

The mouth has teeth and the anus has an anal column, just as the teeth open from the throat. The anal column is such a muscle rope, just like a toothless old man or an old lady. It's no exaggeration. Some strange diseases will lead to long anal teeth, which come out of the anal column.

It is estimated that Nu Wa was lazy when she made people, that is, she made an anus with her mouth as a template.

People are so strange. Originally, they are different from horses and cattle, but if you analyze them carefully, you will find that they come from the same source.

For example, kidney and testosterone (a) pills are cousins, and kidney is almost an enlarged version of * *. The two of them played together until the moment before they were born.

There are abundant sublingual venous plexus under the tongue and super developed internal and external rectal venous plexus in the anus. This terminal venous plexus is almost a spider web lying around the anus.

At present, there are many theories about the etiology of hemorrhoids, such as falling theory and varicose vein theory, but they are inseparable from this venous plexus.

Sitting and standing for a long time, going to the bathroom to see the mobile phone, squatting for half an hour and plugging foreign bodies in the anus are the culprits of hemorrhoids.

Many people have a Baijiu feast on the head, second days of headaches, and anal pain. This is because a lot of stimulant food can cause congestion at the end of the blood vessels.

Over time, the blood vessels were blown big and thick by the blood, and then they became congested. Then the congested blood vessels became a bag with the surrounding fat.

Suddenly one day, the bag suddenly fell out of the anus and hung in the anus like a ball. This is the origin of hemorrhoid prolapse.

Hemorrhoid prolapse not only looks strange, but also hurts. It's like wringing pain after incarceration. It can make a strong man cry and scream with rolling tears: Yao! Yao! Yao!

What hero has no tears? Let him have a prolapse.

There is a white line at the mouth of the anus, which tightens the place derived from the intestine like a rubber band. This is the boundary of the famous internal and external hemorrhoids.

Above the white line are internal hemorrhoids and below the white line are external hemorrhoids. Of course, since there are internal and external hemorrhoids, there is mixing.

Anal fistula is another kind of disease. 90% of anal fistula is caused by perianal abscess. This thing is to open a hole in the ass directly to the intestines, forming an anus without anal column!

Anal fistula treatment is troublesome. If there is incision treatment, directly and violently cut the lumen to let the body grow new granulation and block, which is very painful.

The second is thread hanging therapy. Use rubber band or corrosive medicine thread to enter through the fistula opening on the ass, then pass through the rectum and finally exit from the anus, and then tighten it.

In fact, it is to use a rope to ligate the tissue in the anal fistula channel, make it ischemic and necrotic, and then rely on the body to grow new tissue.

The third is to directly cut off the whole fistula. It was originally a thin channel of toothpick, cut it into a thick channel of chopsticks, and then sew it up.

The most terrible thing is complex anal fistula, which can't be treated. Can only hang line drainage, in professional terms: life with fistula is also a safe choice. All the way, all the way!

Because of some special anal fistula, once the prediction is insufficient, the levator ani muscle is damaged during treatment, which is a big deal. Maybe if you take a cool breath, you can spit fecal residue from your anus.

"Lift the bed!" After cleaning up, Zhang Fan stood in front of the operating bed and said to the itinerant nurse. The advanced operating table is like a tower crane. Below is the cross triangular hydraulic steel bar. After it is slowly unfolded through electric remote control, the bed will rise.

The old-fashioned operating table is like an old-fashioned cannon. When raising the bed, the itinerant nurse has to grasp the disc with a handle to rotate, because without a booster, people with no strength on their arms can't shake at all.

After adjusting the operating table, Zhang Fan began the operation. This kind of operation is very simple.

Use a guide wire that has a certain hardness but can turn, like a fine guide wire like a hard plastic rod, with a silk thread tied at one end and enter slowly.

Anal fistula is not necessarily a straight line. It is just like people who bully the soft and fear the hard. When it meets places with rich vascular plexus and many systemic immune factors, it goes around.

Zhang Fan slowly inserts the plastic rod into the anal fistula. This must not be in a hurry. Otherwise, he either goes the wrong way or is inserted into the normal fat layer.

This kind of surgery is usually done by married doctors. Unmarried doctors can't do it, especially single Wang. He doesn't know what it means to take his time. Zhang Fan has a system, so he will.

The guide wire with silk thread entered the anal fistula little by little. Zhang Fan was close to the patient's anus, which was disinfected, otherwise he would be smoked to death.

Zhang Fan closed his eyes and felt the direction of the guide wire through the feeling of his hands. Bit by bit, when he suddenly felt a sense of breakthrough, Zhang Fan knew that at this time, the guide wire entered the rectum.

Even textbooks say it is a sense of breakthrough, but what is a sense of breakthrough. Insertion into the normal fat layer is also a sense of breakthrough, and protruding from the fistula is also a sense of breakthrough.

How do novice doctors know. Really, this feeling can only be realized after getting married. For example, when you play with balloons, the moment you break the balloon with your fingers is a sense of breakthrough.

Those who don't understand will never understand. Those who understand will understand as soon as the teacher says.

For example, Zhang Fan now closed his eyes and felt the sense of breakthrough from the guide wire. He understood that he entered the rectum and absolutely did not enter fat.

After entering the rectum, be more careful. The intestinal wall of the rectum is very thin, which is easier than inserting the fat layer. It's funny if you poke a hole in the rectum without proper force.

Feel, experience, in this kind of operation without visual conditions is too important. It's true that more than one operation can lead to more than one operation.

Experience can be practiced through work.

The cultivation of hand feeling is very troublesome. We should touch more and practice more, but we can't practice too much.

For example, the sensory system of the hand abdomen is the most sensitive, but once used too much, the skin of the hand abdomen becomes keratinized, and the sensitivity decreases.

So Zhang Fan never does housework at home, just to keep his hand skin sensitive.

After entering the rectum, Zhang Fan then used soft force to turn the guide wire from the opening to parallel the rectum. This is a small difficulty. What is kneading strength? For example, when you quarrel with your wife, you push others, and then pull a little strength to your arms. This is soft strength.

"Tooth tweezers!" When Zhang Fan felt close to the anal door, he said to Zhuang Hongxu.

Zhuang Hongxu handed the forceps to Zhang Fan. Release and close, the tooth tweezers slightly open the small mouth, and then insert it along the anus. When the tooth tweezers enter about three or four centimeters, open it.

Direct is a simple anal dilator.

"Come out, come out." The itinerant nurse had sharp eyes and saw the black guide wire for the first time. Zhang fan pulls the thread head of the guide wire head and the tail of the guide wire in his hand.

Here comes the difficulty of the operation. Although the front is difficult, there are still traces to follow. But the last step is really all based on experience.

Not only Zhuang Hongxu, but also the bed doctor stared at Zhang Fan's operation.

Zhang Fan, with a guide wire in one hand and a rubber band in the other, slowly began to operate

Several assistants stared more and more. This step was the most critical step when the operation fell down. The former director couldn't explain at all, and Zhang Fan spoke again at this time~
