After introducing the instrument, referring to interventional surgery, there are two steps to treat the child under fluoroscopy.

The first is to determine whether the tube enters the human body in place, whether the tube is fixed well, and whether the fixed airbag volume will be too large or too small.

Dr. Yang skillfully used the operating rod to see through the anus of the child. A small bright ball on the machine screen showed that the airbag fully filled the anus.

If the tube is not leaking or running, you can inject air. At this time, the injecting air is not for treatment. As for the interventional procedure, you must first determine whether the preoperative diagnosis is correct before you can start.

When performing examination and diagnosis, the gas injection volume does not need to be large, as long as it runs at the lowest insurance pressure value, which is generally 8kpa. This number is set first when Dr. Yang and his colleagues debugged the machine in the examination room. Now they only need to start the gas injection program remotely.

The gas whirls into the child's intestine duct, and the intestine duct is not blown.

Dr. Yang took the operating rod and completed continuous perspective of each part. On the screen, you can see the distribution diagram of the shiny group of injected gas gradually moving forward and spreading in the child's intestinal duct.

As long as you see through it, 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 diagnosis is to first impress the gas to the lesion of the lesion. Before this, the gas must pass through a long intestine during the advancement of the intestinal duct. The human intestine is not smooth like a tube, and it is like a 18 bend. The statement of 18 bends is exaggerated. It is undeniable that there are some bends in the intestines that are difficult to pass even under normal circumstances. The most famous places of these physiological bends are spleen quint and liver quint.

The spleen flexion is located in the upper left vaginum of the human body and is the corner from the transverse colon to the descending colon. Because it is located near the spleen, it is called colon spleen flexion.

How difficult is this turn? It is said that when colonoscopy is undergoing colonoscopy, the most troublesome thing for the colonoscopy doctor to let the tube pass through this place smoothly.

The excrement and stool in the human body occasionally gets stuck in this place. Clinical patients suffer from pain under the left rib after meals or eating. They may have been checked for a long time and suspected that pancreatitis and other results were not cured. In fact, there is a problem with spleen flexion. Excessive adhesion of the colon, spleen flexion and flexion, develop into benign stenosis, blocking gas and stools, causing discomfort in the patient, which is called spleen flexion syndrome.

Back to the current child, the gas on the machine screen enters from the anal canal to the rectum and then to the sigmoid colon. Through the descending colon, it is necessary to retrograde from the extremely difficult corner of the colon to the transverse colon.

Dr. Yang gradually showed some severe breath on his face. Now that the injected air volume is small, you can test the pressure value that can be withstand at the bend of the intestinal duct here to avoid bursting the intestinal duct here when the air volume is increased.

The amount of gas distributed when the gas passes through the splenic flexor of the child is relatively low, and it can be seen that the resistance encountered by the gas is extraordinary. Is it because of intestinal obstruction caused by intestinal intussusception in the front? Or is the physiological part of the child itself flexed? It is difficult for the doctor to explain it clearly. The key reminder to the doctor is that if the air volume is increased later, there will be very few options.

The difficulty after spleen vermip is liver vermip.

Liver quint is the corner from the ascending colon to the transverse colon, and the physiological structure reaches a 90-degree curve. Because its location is called colon liver quint under the liver. After Liver quint is the ascending colon and the cecum is immediately followed by the ecology, which is very close to the ileocecal part of intussusception.

Dr. Yang picked up the intercom and spoke to the doctor in the examination room: "Dr. Duan, I'm afraid it's not OK."
