Magnifying electronic endoscopes are frequently used to evaluate the pit patterns of the colorectal mucosa, but such endoscopes suffer from a number of problems. For example, they tend to have long, hard tips and heavy controller sections. In addition, the magnified endoscopic images obtained are often quite coarse due to the small number of pixels in the charge-coupled device (CCD). As a resul...

متن کاملAnimal experimental studies using small intestine endoscope
AIM To assess the feasibility and safety of a novel enteroscope, negative-pressure suction endoscope in examining the small intestine of a porcine model. METHODS In vitro experiments in small intestinal loops from 20 pigs and in vivo experiments in 20 living pigs were conducted. RESULTS In in vitro experiments, a negative pressure of > 0.06 MPa was necessary for optimal visualization of the...
