An endoscopic screening system uses an apparatus has an endoscope with an upper/lower wheel and a right/left wheel for controlling bending of an endoscope tip within an organ being imaged an intelligent mouthpiece adapted to precisely measure inclination of the endoscope using marks in degrees in both the novel mouth piece and in the new shaft an endoscope shaft having both cross and longitudinal marks along a longitudinal length for digitalization of output to precisely obtain the length of insertion from a reference point to a tip of the endoscope and an angulation device for measuring rotation of the upper/lower and right/left wheels. Every portion/part/side located within an organ is already assigned an alphanumeric code as part of the new nomenclature. The endoscopic screening system allows for imaging sequentially of an entire interior surface of a portion of the patients gastrointestinal tract and image reconstruction of the surface with overlapping redundant pictures without image gaps.
