To understand the meaning of "black esophagus", first of all, we need to clarify a concept - whether the esophagus is originally black.

This is of course a nonsense. None of the organs inside the human body is naturally black. The human body can naturally show black, except for hair, there are only skin and iris.

So, under what circumstances will the organs change color?

First of all, when exposed to certain dyes, some organs may discolor. For example, the indigo carp injection that Sun Lien once used to scare people to play may turn blue in a short period of time. Smokers who smoke for a long time may have black spots in their lungs due to tar attachment.

In addition, Pseudomonas aeruginosa will cause green pus to appear in the infected area, and jaundice will cause the iris and skin to be stained with a dark yellow...but there are very few black cases.

There may be many explanations for the external skin to turn black, but the internal organs to turn black... Sun Lien can remember the possibility that necrosis is immediately - that.

This cannot be blamed for Sun Lien for having too little knowledge. After all, more than half an hour ago, he saw Chen Tianyang and Dr. Wang release 1.4 liters of necrotic tissue fluid and pus from the buttocks of a Nigerian soldier. Now when he sees "black" and "purple-red", Sun Lien's mind is filled with the sound and smell of the liquid from the stainless steel basin that fell into his hands.

The Russian in front of him spoke English, but the subsequent communication was obvious that he could no longer let the other party use this kind of Russian with a big Lipa flavor. He searched around the house and finally found a translator who was not too serious and could speak English Russian and Chinese - the Pakistani captain who just smiled bitterly and said that he had a stomachache.

I have to say that the comrades in Pakistan are caring. Sun Lien just wanted to understand the basic situation of the Russian in front and ask about his medical history. Unexpectedly, the Pakistani captain actually had a good relationship with Peter. He didn't even ask Peter to say anything more, but began to tell what he knew.

Peter was born and raised in the Soviet Union. But after he joined the army, the Soviet Union disappeared.

As an armored soldier repairman, Peter was the last group of retired soldiers in his armored division. First, the gunners were discharged in batches because they were sold out of ammunition, and then the armored soldiers left because they had no tanks and armored vehicles. Finally, Peter was taken to the streets of Vinnica by the regiment commander in a truck he repaired and gave him five thousand rubles - this was the dividend he helped repair the tanks and then sold them to the arms dealers.

The Soviet Union disappeared, the tanks disappeared, and even Peter's identity as a soldier disappeared. Mechanics like him were almost everywhere in Russia. Peter, who could not even have a full meal, finally decided to exchange all his wealth for vodka and a one-way air ticket to Nigeria.

After arriving in Nigeria, Peter found a job to perform mechanical repairs in the Nigerian army. He would fall asleep in guilt and regret every day, and then wake up deeper pain. Day after day alcoholism lasted for more than twenty years, and if he didn't drink a whole bottle of vodka every day, he would even be weak and unable to move.

Speaking of this, the Pakistani captain sighed helplessly and explained to Sun Lien, "This kind of thing happens to any soldier who loves his country, and will bring the same ending, but these northern neighbors have indeed drunk more...."

Sun Lien blinked, but he had no objection to listening to the story. But the prerequisite was that the story would help him diagnose the condition. The Pakistani captain mumbled for a long time, but there was no useful information, which made Sun Lien a little anxious.

"Have he had any obvious stomach upset recently? Acid reflux or vomiting?" Because he couldn't hear the information he wanted, Sun Lien directly started to ask the Pakistani captain. Although he was not sure what the disease of black esophagus was, it seemed that at least he had to give Peter a gastroscopy to make a clear diagnosis. Therefore, Sun Lien tried to guide the topic on Peter's symptoms, preferably it sounded like a gastroscopy or something, so that he could prescribe a gastroscopy examination item.

"Yes, he has vomited blood three times recently, and the amount is not very large each time." The Pakistani captain said after communicating with Peter for a few words, "and he has been feeling a little dizzy and exhausted lately."

If you drink a pound of vodka a day and feel dizzy and exhausted, it only means that this person can drink it very much. Sun Lien decisively skipped the description and asked, "What kind of blood is you vomiting? The black one, like caviar?"

"No, it's blood, bright red." The captain shook his head. "He said that after he vomited, he found that there was blood. He had nausea and stomach acid before, but he never vomited blood."

There are many considerations about the types of blood related to the digestive tract. The most basic thing is to look at the color and shape of the blood to determine whether the bleeding point is in the esophagus or below the esophagus. If it is gastric bleeding or duodenal bleeding below the esophagus, the blood will be coagulated by the stomach acid and digestive enzymes in the stomach and form a black semi-solid. Sometimes, less severe gastric bleeding or duodenal bleeding can also be manifested as black stools.

The bright red blood vomited, which means that the blood flowing out after the damage did not contact the gastric acid and digestive enzymes in the stomach. This directly allowed Sun Lien to lock Peter's symptoms of digestive tract bleeding above the cardia and the place where his throat fell.

Combined with the black esophagus prompted by the status bar... Sun Lien frowned. This can't be a ruptured vein in the esophagus?

There is a complex blood supply structure inside the esophagus. Even if a certain vein is broken, there should not be a diagnosis of "black esophagus"... Sun Lien couldn't figure out what was wrong, but Peter's current symptoms were enough for Sun Lien to make a gastroscopy decision - the cause of gastrointestinal bleeding is to be investigated. He thought about it and wrote three possible guessing directions on the diagnosis sheet in front of him, "peptic ulcer?", "acute gastric mucosal lesions?" and "gastrointestinal tumors?"

Of course, Sun Lien would not write the "black esophagus" on it, he is not so slutty yet. However, judging from the current situation, it is still necessary to do a more detailed examination. After drinking more than twenty years in a row, he knows what irreparable damage alcohol has caused to Peter's body.
