Core Tip
Core tip: The triradiate fold is often described as a major landmark of caecal intubation in colonoscopy, but its frequency of visualisation has not been previously documented. This study shows that identification of the triradiate fold is infrequent and its presence is subjective. Inclusion in guidelines or colonoscopy software programs as a sole marker of complete colonoscopy is questionable.
