Biopsies are employed method for obtaining a portion of tissue or cells in the body, with the aim of examining them under a microscope. They can be performed through an endoscope or a lamparoscopia which is introduced into the body (eg, abdomen) and obtain the sample by scraping, a cut or a small extraction element studied by suitable instruments. Some biopsies require total sedation and other simply a local anesthesia, depending on the procedure employed. The biopsy of the small intestine is the method used to extract a portion of tissue and cells of the body for further analysis and study. This type of biopsy requires full sedation and is performed by inserting an endoscope (small, flexible tube fitted with optical fiber) through the mouth (although occasionally also inserted through the nose). The tube is fed up to the part of the small intestine which are interested in obtaining a tissue sample. Thus, one can detect and diagnose possible pathologies of the small intestine.
