What is the difference between enteroscopy and colonoscopy?

In clinical practice, people often experience symptoms of gastrointestinal bleeding, accompanied by abdominal pain or diarrhea. Many times, patients have no way of knowing the real cause. At this time, they need to use scientific instruments for examination, including small enteroscopy. This method can identify the cause of the disease. So what is the difference between the popular small enteroscopy and traditional colonoscopy?

The difference between enteroscopy and colonoscopy:

What is commonly referred to as enteroscopy refers to colonoscopy. In a narrow sense, enteroscopy can be understood as including small enteroscopy and colonoscopy, both of which are a way to conduct visual examination of intestinal lesions.

Suggestions: For patients with unexplained blood in the stool, abdominal pain, etc., colonoscopy may be considered. I wish you good health.

Generally, there are no mirrors that long. This is very normal in a well-off society. Well, generally there are no small enteroscopes. The main thing is a capsule-type small enteroscope, which is used for colonoscopy, mainly starting from the anus.

If you want to see the entire digestive tract clearly, you can make a capsule, an endoscope, which can be swallowed into the mouth and pass through the esophagus, stomach, small intestine, and large intestine and then be directly excreted. This way, you can see the lesions of the entire digestive tract clearly. However, its disadvantage is that you cannot take the pathology after seeing the lesions.

I want to know the colonoscopy situation, which is very troubling.

Guidance:

The human intestine is divided into the large intestine and the small intestine. The small intestine mainly functions for digestion and absorption, while the large intestine mainly functions for storage and excretion of waste. The functions between the two are different, which determines that the functions that need to be checked are also different, so they need to be done separately.

The length of the intestine is actually very long, so the mirror is not that long.

Guidance:

It is recommended to observe temporarily. Colonoscopy can only be used for the large intestine, and gastroscopy can only see the duodenum, so the small intestine is a blind spot and can only be examined with a capsule endoscope.

Enteroscopy procedure:

(1) The patient lies on his left side and the enteroscope is inserted into the stomach cavity in a similar manner to gastroscopy. A small amount of air is injected and the stomach cavity is slightly dilated before the endoscope is inserted.

(2) Entering the duodenal bulb through the pylorus, 10 mg of scopolamine or 20 mg of spasmolyte are injected intravenously to reduce small intestinal peristalsis. If necessary, 10 mg of diazepam (Valium) or 50 mg of pethidine are injected intravenously. (3) The endoscope is inserted into the descending duodenum using the ERCP method. The endoscope is then advanced along the cavity using the hook-and-pull method. When the endoscope has penetrated about 100 cm, the lens has reached or exceeded the ligament of Treitz. The hook-and-pull method can be used to eliminate the sharp angle of the intestinal loop and the bend of the endoscope body. The endoscope is then advanced along the cavity by adjusting the angle knob and injecting a small amount of air. Generally, the endoscope can be smoothly advanced into the jejunum. After passing through the Treitz ligament, the direction of the mirror body can be divided into two types: clockwise (right type) and counterclockwise (left type), and the counterclockwise type is easier to insert. Generally, it can be inserted into the upper jejunum 50-60cm. If a sliding tube is used, it can be inserted to 120cm below the Treitz ligament. (4) Enteroscopy is usually performed while observation is performed while the endoscope is advanced, and detailed observation is performed during the process of withdrawing the endoscope. If any abnormality is found, video recording and biopsy can be performed. The exact location of the lesion can also be determined with the help of X-ray fluoroscopy or abdominal plain film.
