Preface
Endoscopy was started by the desire to see the inner body, and it has become a vital tool in modern medicine. Since the
first direct visualization of the gastrointestinal (GI) tract with traditional endoscope over 50 years ago, we have
seen the fast development from rigid esophagogastric scope to high definition flexible videoscope. Also, in an effort
to detect early or precancerous lesion in GI tract, the imaging technologies such as narrow band imaging, autofocus
imaging, magnified endoscopy, and confocal microendoscopy have developed.
Now, we publish the first book entitled “Natural Image Endoscopy including Storz Professional Image Enhancement System
(SPIES)”. Three innovative technologies for visualization are integrated in the new endoscopic system and provide
versatile visualization options to operators. We want to offer a new insight into how the human GI tract is visualized
through this advanced equipment.
I would like to acknowledge the valuable assistance of Dr. Ga Won Song and Dr. Weon Jin Ko. I would also like to thank
the JW medical and KARL STORZ. Finally, I sincerely hope that this book will be helpful for endoscopists who have a
desire to move toward more advanced endoscopy.

Testimonial
Gastrointestinal (GI) endoscopic examination is the most fundamental and prerequisite clinical method to diagnose and
treat various GI diseases. Since the first electronic endoscope was developed in 1983, the technology of endoscopy has
rapidly advanced. Video endoscopes with built-in CCD (charge-coupled device) were developed and introduced into
clinical field in 1987. The manufacturer put an initial consummation of the endoscopic system on the market, and now it
is widely used by the most gastroenterologists. With the further advancement of the image technology, very high
resolution endoscopic system can be available. Since the summer of 2014, Dr. Cho and his colleagues have studied the
newly developed color spectrum shifting technology from Karl Storz (Germany). This system allows recognition of the
finest tissue structures. I am sure this book will give useful tips to beginners and expert endoscopists. And, I am
looking forward to use high quality endoscopes made by Korea.
