Conclusion: most patients with superior alimentary canal foreign bodes have a history of abnormal deglutition, several with extreme personality

amd it is difficult to detect foreign body in stomach because there are too much food. Usually doctors need to use X-ray to make a definite diagnosis. Electronic gastroscope has important implications for the diagnosis and treatment of superior alimentary canal foreign bodies.

Methods: The existing endoscopic ultrasonography (EUS) cannot detect the small intestine directly for the limited length of its probe. But it can do this on the patients whose digestive tracts have

been shortened after operations on esophageal, stomach, duodenum, large intestine or laparotomy. Thus the patients should be screened. 50 patients were chosen out of the patients who stayed in Shanxi Coal Center Hospital Digestive Endoscopy Center, and who have been checked with capsule intestine, gastroscope, colonoscopy check details and double-balloon enteroscopy, as well as the patients who stayed in General Surgery and Digestive Surgery and who had intestinal checking during the operation. All the 50 patients have intestinal endo-luminal ultrasound, observe the imaging features of the normal small intestine and those with diseases, and take down the thickness of every small intestine wall layer and the characteristics. If any disease is found, Tolmetin the patient should have US and SCT, so as to decide the value of intestinal endo-luminal ultrasound in getting the imaging features of

the normal small intestine and its application in diagnosing disease of small intestine. Results: Of the 50 patients, 47 had ISUS, of whom 10 have diseases. The normal small intestine wall has six layers while the jejunum and ileal has totally different imaging features and their separate characteristics. The jejunum wall and ileal wall which have tapetum is high-level echo – high-level ech – low-level echo – high-level echo – low-level echo – high-level echo from inside to outside. Those without tapetum is high-level echo – low-level echo – high-level echo – low-level echo – high-level echo from inside to outside. The layer thickness of jejunum is measured to be about 1.5–2.0 mm, ileal 1.8–2.2 mm, tapetum in jejunum 0.4 mm, tapetum in ileal 0.2 mm.
