BACKGROUND: Faecal urgency and incontinence with rectal hypersensitivity is a distressing, unexplained disorder that is inadequately treated. We aimed to determine whether expression of the heat and capsaicin receptor vanilloid receptor 1 (TRPV1 or VR1) was changed in rectal sensory fibres, and to correlate nerve fibre density with sensory abnormalities. METHODS: We compared full-thickness rectal biopsy samples from nine patients with physiologically characterised rectal hypersensitivity with...Expand abstract
