Rectal retroversion is a common procedure during a colonoscopy. Although recommended by experts as an essential step of colonoscopy, the impact of retroversion on the detection of polyps is controversial. According to published data, systematic rectal retrovision adds little value in the detection of rectal polyps when following careful examination in axial vision. In case of narrow rectal light, this procedure has no interest compared to the axial vision and is not deprived of of complication. On the other hand, it is useful and safe to examine the posterior wall of a wide rectum. The retroversion may be essential to complete or allow the excision of polyps of the lower rectum. Rectal retrovision also seems useful for performing multiple ligations of internal haemorrhoids in one time.
