About this study

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.
