Proximal retroflexion versus second forward view of the right colon during screening colonoscopy: A multicentre randomized controlled trial.

ABSTRACT:

Background

Colonoscopy is the gold standard investigation for the detection of colorectal cancer, but the right colon is more difficult to examine than the left colon. A second examination of the proximal colon has the potential to reduce rates of missed pathology.

Objective

To determine whether proximal retroflexion improves the adenoma detection rate or other outcomes in the right colon compared with the forward view.

Methods

We performed a multicentre randomized controlled trial of patients from the colorectal cancer screening programme with a positive faecal immunochemical test. Patients were randomized to a second right colon examination using proximal retroflexion or forward view.

Results

A total of 692 patients were included. A second examination of the
