has been performed since the early nineteenth century, and originally
involved the use of alcohol or turpentine lamps as light sources
for rigid instruments.1 The birth of modern endoscopy can
be dated to the 1960s with the development of flexible fiberoptic
instruments. These allowed visualization of areas beyond the reach
of rigid instruments and greatly improved patient comfort. The development
of fiberoptic illumination further improved endoscopic safety by
removing thermal and electrical complications from the procedure.
Flexible fiberoptic endoscopes were further modified in the 1980s
by replacing fiberoptic image bundles with a charge-coupled device
(CCD) video camera, which provided greater image detail and display
on a video screen. CCD chip size has become smaller over time, further
allowing the size of endoscopes to become smaller...."
