Visceral hypersensitivity has been recognised as a characteristic of patients with irritable bowel syndrome (IBS). It may be involved in the pathogenesis of abdominal pain/discomfort, and seems to result from the sensitisation of nerve afferent pathways originating from the gastrointestinal tract. From a clinical point of view, hypersensitivity, although frequent, is not a constant finding among patients with IBS and cannot therefore be considered as a diagnostic marker of the condition. The advances made in understanding visceral hypersensitivity in patients with IBS are reviewed: the factors that influence abdominal distension are defined and different therapeutic perspectives are examined.
内脏高敏感性已被公认为肠易激综合征(IBS)患者的一个特征。它可能参与腹痛/不适的发病机制,似乎是由源自胃肠道的神经传入通路致敏所致。从临床角度来看,高敏感性虽然常见,但并非IBS患者的恒定表现,因此不能被视为该疾病的诊断标志物。本文综述了在理解IBS患者内脏高敏感性方面取得的进展:明确了影响腹胀的因素,并探讨了不同的治疗前景。
