FIT negative cancers: A right-sided problem? Implications for screening and whether iron deficiency anaemia has a role to play.

Introduction: Faecal Immunohistochemistry Testing (FIT) is recommended as an adjunct to guide referrals from Primary Care for individuals without rectal bleeding, who do not meet the suspected cancer pathway referral guidelines. It has largely replaced Faecal Occult Blood Testing.

Aims: To assess the specificity of FIT.

An unusual triad of pneumatosis intestinalis, portal venous gas and pneumoperitoneum in an asymptomatic patient.

Pneumatosis intestinalis (PI) is defined as the presence of gas within the serosal or mucosal layer bowel wall. This sign is usually found upon radiographic imaging and is most commonly secondary to acute gastro-intestinal ischaemia. Fifteen per cent of cases can present with a primary condition called pneumatosis cystoides intestinalis (PCI).
