A randomized, multi-observer, comparative evaluation of conventional fiberendoscopy and videoendoscopy in the upper...

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.
