enteroscopy

Enteroscopy is the most commonly used method for the examination and diagnosis of chronic gastrointestinal bleeding and various intestinal diseases of unknown etiology. Unexplained gastrointestinal bleeding, small bowel, malignant tumors, assisted surgeons in small bowel examinations during surgery. Basic Information Specialist classification: Digestive examination classification: X-ray Applicable gender: whether men and women apply fasting: not fasting Tips: Drink water and food before check-up, and other drinks. Normal value There was no obvious cause of abdominal distension, obvious lower abdomen, no diarrhea, abdominal pain, and CT showed thickening of the small intestine wall. Clinical significance Abnormal results: holes and hemorrhage, nasal injection when entering the enteroscopy. People who need to be examined: unexplained gastrointestinal bleeding; small bowel, malignant tumors, assisting surgeons in small bowel examinations during surgery. Precautions Taboo before check-up: drinking water and eating, and other drinks. Requirements for examination: The patient takes the left lateral position. Inspection process (1) The patient takes the left lateral position, and the gastroscopic examination operation inserts the enteroscopy into the gastric cavity, and a small amount of gas is injected, and the gastric cavity is slightly extended before entering the mirror. (2) through the pylorus into the duodenal bulb, at this time intravenous injection of anisodamine 10mg or Jieqiling 20mg, in order to reduce intestinal peristalsis, if necessary, intravenous injection of diazepam (diazepam) 10mg or pethidine 50mg. (3) According to the ERCP method, enter the endoscope, enter the duodenal descending part, and use the hook-and-pull method to enter the mirror. When the endoscope reaches about 100cm, the lens has reached or exceeded the flexor ligament, and the hook can be applied. The method eliminates the acute angle of the intestinal fistula and the bending of the lens body, and advances through the cavity by adjusting the angle button, and a small amount of gas injection can generally enter the jejunum smoothly. After the ligament of the flexor, the direction of the lens body can be divided into two types: clockwise (right) and counterclockwise (left), which are easy to insert counterclockwise. Generally, it can be inserted into the upper jejunum 50-60cm. If a slide tube is used, it can be inserted into the ligament of the flex. (4) Small colonoscopy usually observes while advancing, and then carefully observes during the retreat. If abnormalities are found, video and biopsy can be performed. The exact location of the lesion can also be determined by means of fluoroscopy or abdominal plain film. Not suitable for the crowd There are endoscopic contraindications, acute pancreatitis or acute biliary infection, extensive adhesions in the abdominal cavity.
