Haematochezia - look below

Local rectal pathologies are recognised causes of bright red rectal
bleeding with haemodynamic shock [1]. Rectal ulcers, haemorrhoids and most
other anorectal pathologies can be controlled by simple local
interventions. It is both embarassing and negligent to expose patients
to ionising radiation without first excluding anorectal causes by
proctoscopy and sigmoidoscopy. It would be even more deficient to proceed
directly to laporotomy in a patient with bleeding piles[2]. In the absence
of coherent national guidance, the authors of local guidelines should
stress the need to exclude anorectal causes in patients presenting with
haematochezia, regardless of their haemodynamic status
