In a comparative, histologically controlled study, no significant difference was found
in the accuracy of conventional fiberendoscopy and videoendoscopy in the diagnosis
of upper gastrointestinal tract lesions. Both techniques permitted accurate description
of focal and/or ulcerative lesions, but videoendoscopy did not provide better sensitivity
than fiberendoscopy in the diagnosis of superficial, non-ulcerative, inflammatory
changes. The same results were obtained on checking the reproducibility of the macroscopic
diagnosis by a delayed review of recorded videotapes.
