Rectal spasm: Motility, compliance, & sensation of the rectum are important to fecal continence. Hypersensitivity to distension & abnormal motility patterns in the rectum are common in irritable bowel syndrome. In ibs-d patients, fecal urgency & cramping lend further to a hypersensitive rectum. Clinical testing distinguishes ibs from levator ani muscle dysfunction, sphincter dysfunction, dyssynergia, proctalgia.
