简要总结
The aim of this study is to evaluate the examination of the proximal colon with the retroflexion colonoscopic technique in terms of feasibility and its possible additive contribution in the detection of important lesions, namely polyps and cancers.
详细描述
The investigators prospectively examined the additional diagnostic yield of right colon examination with colonoscope retroflexion in consecutive, symptomatic and screening - surveillance patients. Right colon was examined in forward-view first and thereafter, retroflexion was performed to re-inspect it.
