 Rigid endoscopy as the proof of concept: invisible could be visible: the first step toward exploration of the esophagus and the proximal stomach.

 Semiflexible endoscopy as the next step toward correct diagnosis of gastric pathology beyond the gastric body and development of endoscopic target biopsy.

 Fiberoptic flexible gastrointestinal endoscopy as the foundation of modern diagnostic and therapeutic pediatric gastrointestinal endoscopy – more recently, videochip at the tip.

During the last half century, two achievements can be considered as major advances in the field of gastroenterology: the adaptation of fiberoptics to gastrointestinal endoscopy, and, as a consequence, the discovery of Helicobacter pylori [1,2]. Indeed, the role of H. pylori would not have been suspected without the pathologic and microbiologic study of biopsy material obtained with the endoscope. Attempts to inspect in vivo the internal cavities of the human body are probably as ancient as medicine itself. The challenge was to find a safe source of light that would not generate heat that could damage tissues.
