Zusammenfassung
Introduction: Somatosensory hyperalgesia in the referred pain area (RPA) reported in patients with abdominal pain syndromes, which may result from convergence of nerve fibres from visceral and somatic tissue at spinal and supraspinal levels. Persistent hyperexcitability of neurons in the CNS may explain chronic biliary pain in PCS patients (i.e. biliary hypersensitivity) despite the original disease has been eliminated (cholecystectomy and sphincterotomy). The aim of the present study was to evaluate cutaneus neural sensibility in the referred pain area in PCS patients with persisting biliary pain before and aft…
