   First, it is to determine whether the tube is in place in the human body, whether the tube is fixed well, and whether the fixed airbag is too large or too small.

   Dr. Yang skillfully used the joystick to see through the **** of the child. A bright small group appears on the screen of the machine, indicating that the airbag has fully filled the anus.

   The tube is not leaking or running, so you can inject gas. At this time, the gas injection is not for treatment first. It is the same as the interventional surgery procedure. It is necessary to judge whether the preoperative diagnosis is correct before proceeding.

   When performing inspection and diagnosis, the gas injection volume does not need to be large, as long as it runs at the lowest insurance pressure value, generally 8kpa. This number was set by Dr. Yang and the others in the examination room to debug the machine. Now they only need to start the gas injection program remotely.

  The gas breathed into the child\'s bowel, without blowing the bowel.

   Dr. Yang uses the joystick to complete the continuous perspective of each part. On the screen, you can see the distribution map of the injected gas shining group gradually spread in the child\'s bowel.

   As long as you see it through perspective, it can be said that all operations are carried out in an orderly manner under the control of the doctor. The next question is whether this operation can successfully achieve the goal.

   The first step in the diagnosis is to pump the gas to the ileocecal part of the lesion. Before that, gas had to travel a long length of the intestine as it progressed through the bowel. The human intestine is not as smooth as a tube, and the twists and turns are like eighteen bends. The eighteen bends statement is an exaggeration. It is undeniable that some bends in the intestines are difficult for gas and liquid to pass through even under normal circumstances. The most famous of these physiological curvatures are the spleen and liver flexures.

  The splenic flexure is located in the upper left abdomen of the human body, and is the corner from the transverse colon to the descending colon. Because of its location near the spleen, it is called the splenic flexure of the colon.

   How difficult is this turn to turn? It is said that when performing colonoscopy, it is the most troublesome for colonoscopists to make the tube pass through this place smoothly.

  The excrement and feces in the human body will occasionally get stuck in this place. Clinically, some patients have pain under the left rib after eating or eating. It may have been checked for a long time for gastritis, suspected pancreatitis, etc. The results were not cured. Excessive flexion and adhesion of the splenic flexure of the colon develops into a benign stenosis, which blocks gas and stool and makes the patient uncomfortable. This is called splenic flexure syndrome.

   Back to the current child, the gas on the machine screen shows that the gas enters the **** canal to the **** and then to the sigmoid colon. After passing through the descending colon, it must retrograde from the super-difficult bend of the splenic flexure of the colon to the transverse colon.

   Dr. Yang gradually showed some serious breath on his face. Now the injected gas volume is just small enough to test the pressure value that can be endured at the bend of the intestinal tube here, so as to avoid bursting the intestinal tube here when the air volume is increased.

   When the gas passes through the spleen curve of the child, the amount of gas distributed is relatively low, which shows that the resistance encountered by the gas is unusual. Is the anterior intussusception caused by intestinal obstruction? Or is the child\'s physical part more flexed in this place? The doctor was at a loss for words. The important thing to remind the doctor is that if you increase the air volume later, there will be very few options.

  The difficulty after the spleen curve is the liver curve.

  The hepatic flexure is the corner from the ascending colon to the transverse colon. The physiological structure reaches a 90-degree angle. It is called the hepatic flexure of the colon because of its location under the liver. After the hepatic flexure, the ascending colon is immediately followed by the cecum, which is very close to the ileocecal region where the intussusception occurs.

   Dr. Yang picked up the walkie-talkie to talk to the doctor in the examination room: "Doctor Duan, I\'m afraid it won\'t work."

   Thank you for your support! ! ! Good night dears~
