It is a fact that
performing endoscopy using conventional methods requires substantial time and
development of alternative diagnostic modalities. Replacement of rigid
endoscopes with flexible and digital devices in time, faster performance of the
procedures and reduced time for them to turn back to work brought about the
expectancy. It was possible that easier and more reliable methods could exist.
Idea of capsule endoscopy was born following examination of the
gastrointestinal tract with an endoscope with shape of a capsule. Although idea
of capsule endoscopy was suggested long years ago, it fell behind the advances
in conventional step of the endoscopy, especially developmental speed of the
flexible devices. Furthermore, three-dimensional (3D) organ views can be
processed digitally by means of sophisticated software in the fields of
computerized tomography and magnetic resonance imaging. Thus, virtual
cystoscopy of high resolution and specificity is possible by means of both
methods. Wireless capsule endoscopy is still in the experimental stage.
“Steerable independent intracorporeal endoscope” with feature of consecutive
instillation in addition to its diagnostic utility is not a dream.
