Endoscopic imaging of parasites in the human digestive tract.

There are various diagnostic approaches for parasitic infections, including microscopic identification of parasites in the stool or biopsy samples from the intestinal mucosa, antigen testing of feces or serum, polymerase chain reaction (PCR) testing, and serology. Endoscopy is sometimes used for direct confirmation of parasite infection and as a therapeutic option for removal. In recent years, innovations in endoscopy have advanced remarkably with regards to endoscopic devices as well as diagnostic and therapeutic endoscopical methods. Several new endoscopic devices are now used for diagnostic and therapeutic approaches to parasitic infections. In the present article, we have focused on in vivo imaging of parasitic infections. In vivo images of parasites were obtained using various endoscopic methods such as high-definition endoscopy, super-magnifying endoscopy, and video capsule endoscopy.
