Summary

Missing polyps during colonoscopy is considered an important factor for interval cancer appearance especially in the ascending colon (AC). Aim of the study: To evaluate the contribution of retroflexion to adenoma detection in the AC. Patients-Methods: Prospective observational study included consecutive patients with complete colonoscopy between June 2017 and June 2018. The AC was examined in two phases. The first phase included two forward views from the hepatic flexure to the cecum and the second phase a retroflexion in the cecum, inspection till the hepatic flexure then redressing to forward view and reinsertion to the cecum.

Interventions

PROCEDURE

Retroflexion in the Right Colon

Prospective evaluation of an every day technique (retroflexion) used in our department for many years. The protocol of ascending colon examination encompassed 2 phases: A first phase (1) divided in Forward view (1a) videlicet insertion from the right flexure to the caecum followed by a second forward view (1b) namely withdrawal till the right flexure and reinsertion to the caecum maintaining the endoscope straight and a second phase (2, Retroflexion) with U-turn of the colonoscope in the caecum till the right flexure and then redressing to the forward view and reinsertion to the caecum.
