1. The High Prevalence of Rectal Bleeding in
the Community
The high prevalence of all symptoms in the community, regardless of their
nature, was first described in the Peckham experiment in 1946 [31] and subsequently
by Wadsworth [32] and Hannay [33].These studies demonstrated
that most people have various symptoms most of the time, which they either
self-treat or which resolve spontaneously without medical consultation.
Only a small proportion of patients who eventually consult their doctors
are referred to hospital for investigation [31–33]. This observation is also
true for rectal bleeding [34–36].
