Anorectal and perineal pain Abstract. Anorectal pain is a common clinical challenge in the outpatient office. Anal fissures, anal venous thrombosis, proctitis or neoplasms are frequent etiologies for proctalgia. After exclusion of somatic disorders by diagnostic imaging and endoscopy, functional anorectal pain or pathologies like interstitial cystitits, chronic prostatitis, coccycodynia or pudendal neuralgia should be considered. The Rome IV criteria distinguish proctalgia fugax, a sharp paroxysmal pain lasting for maximum 30 minutes, and the levator ani syndrom. Latter is characterized by a tender puborectal muscle on digital rectal examination and pain lasting for more than 30 minutes. Treatment consists in reassurance, sitz bathes, topical vasodilators and anal massage. Biofeedback is a further option for levator ani syndrome. Painful palpation of the ox coccygis leads to the diagnosis of coccycodynia, a non-functional disorder. Therapy consists in anti-inflammatory medications, os coccygis mobilisation and infiltration therapy. Urologic chronic pelvic pain (chronic prostatitis and interstitial cystitis) as well as pudendal neuralgia, both neurogenic pelvic pain syndromes, can cause pain radiating into the after and perineum. The diagnosis and discrimination from functional rectal pain is difficult. Patients with neurogenic anorectal pain are best treated with anti-inflammatory medications, pain modulating antidepressives, anticonvulsives or local infiltration therapy. Interdisciplinary management of complex pain patients is mandatory.
