Provoked vestibulodynia (PVD) refers to vulvar pain of at least 3 months duration, localized to the vestibule, provoked by touch and sexual activity and occurring in the absence of a clear identifiable cause. The clinical spectrum ranges from mild with distressing discomfort through to severe and disabling pain. Current understanding is that PVD is one of many chronic pain conditions characterized by sensitization of peripheral and central nociceptive pathways, with pain arising due to dysfunctional neuronal activity in the absence of painful stimuli. Pathophysiology is not well understood but is likely a complex interplay of environmental, genetic, psychological and immune factors. Care is multidisciplinary and follows general principles of chronic pain management with the addition of specific therapy tailored to address pelvic floor overactivity, and sexual and relationship difficulties. More recently, the therapeutic use of placebo is gaining traction in chronic pain research and is a very promising adjunctive therapy. The majority of women with PVD are managed outside of tertiary clinic settings, and care depends on availability and affordability of specialized services; however, much can be done by the primary health provider. PVD is common, and highly treatable, especially with early intervention, but unfortunately, many clinicians are unaware of this condition, and the biggest hurdle for women accessing treatment is obtaining a diagnosis. With treatment, most women can expect significant improvement, often with fairly simple interventions, although some women will benefit from referral to specialized centers. The aims of this article are twofold: firstly, to summarize current literature concerning PVD pathophysiology and management; secondly, to provide a framework for clinicians unfamiliar with vulvar medicine to understand and manage PVD.
诱发性前庭疼痛(PVD)是指持续至少3个月的外阴疼痛,局限于前庭,由触摸和性活动诱发,且无明确可识别病因。临床症状范围从伴有令人苦恼的不适的轻度疼痛到严重的致残性疼痛。目前的认识是,PVD是许多慢性疼痛病症之一,其特征是外周和中枢伤害感受通路致敏,在无疼痛刺激时因神经元活动功能失调而产生疼痛。其病理生理学尚未完全了解,但可能是环境、遗传、心理和免疫因素的复杂相互作用。治疗是多学科的,遵循慢性疼痛管理的一般原则,并增加针对盆底过度活动以及性和人际关系问题的特定疗法。最近,安慰剂在慢性疼痛研究中的治疗应用越来越受到关注,是一种非常有前景的辅助疗法。大多数患有PVD的女性在三级诊所环境之外接受治疗,治疗取决于专业服务的可及性和可承受性;然而,初级卫生保健提供者也可以做很多工作。PVD很常见,且高度可治疗,尤其是早期干预,但不幸的是,许多临床医生并不了解这种病症,而女性获得治疗的最大障碍是获得诊断。通过治疗,大多数女性有望显著改善,通常采用相当简单的干预措施,尽管有些女性将受益于转诊至专业中心。本文的目的有两个:第一,总结有关PVD病理生理学和管理的当前文献;第二,为不熟悉外阴医学的临床医生提供一个理解和管理PVD的框架。
