How to screen for small bowel cancer? 4 large imaging examinations of small intestine cancer
Release date: 2017-04-13 How to effectively screen small bowel cancer? Small bowel cancer is a malignant tumor that occurs in the duodenum, jejunum and ileum and is relatively rare. For the screening of small intestine cancer, fecal occult blood test is needed; tumor marker examination: carcinoembryonic antigen, CA-199, CA-125, etc.; at the same time, some imaging examinations can be done: CT, MRI, PET/CT Wait. Below, we mainly to understand the imaging examination of small intestine cancer. Imaging examination of small bowel cancer 1. Small bowel cancer sputum angiography Small bowel sputum angiography can show the location and extent of small bowel disease, but the positive rate is low. The double contrast angiography, especially the intubation method, double angiography of small intestine, makes the diagnosis rate of small intestinal bleeding lesions increased by 10% to 25%. Small bowel sputum angiography has almost no diagnostic value for vascular lesions. 2. Radionuclide imaging Radionuclide imaging is a non-invasive examination, mainly used for the localization of small intestinal bleeding, which is more sensitive than angiography. The positive rate of diagnosis of small intestinal active hemorrhage is 40% to 50%, but sometimes there is a false positive. 3, angiography An angiographic examination is performed in small bowel diseases, especially in gastrointestinal bleeding. This method is an effective diagnosis and treatment method. As long as the contrast agent extravasation is seen, a clear diagnosis can be made and embolization treatment can be performed at the same time. However, this test is affected by the speed of blood loss and the timing of the examination. It is necessary to inject the contrast agent into the blood supply artery at the bleeding site during the active period of the bleeding to be successful. 4, CT simulation endoscopy A dynamic reconstruction image similar to endoscope can be obtained by using spiral CT thin layer without interval scanning and computer three-dimensional reconstruction. The limitation is that the mucosal color change cannot be observed, and the superficial fine structure changes cannot be distinguished, and biopsy and microscopic treatment cannot be performed. Next, let's take a look at the causes of small bowel cancer and prevent the occurrence of small bowel cancer from the source. Causes of small bowel cancer Intestinal cancer may be complicated by Crohn's disease, celiac disease-gluten intolerance, familial intestinal polyposis, etc. If you have Crohn's disease, long-term illness, rickets, surgical removal of the intestines, etc. May cause small bowel cancer. The activation of oncogenes and the loss of tumor suppressor genes are also the causes of small bowel cancer. Diets have a high proportion of animal fats and proteins, and low cellulose content can also induce the formation of small bowel cancer.
