The perianal disease affects up to one-third of individuals with Crohn's disease (CD), causing disabling symptoms and significant impairment in quality of life, particularly for those with perianal fistulising CD (PFCD). The collaborative effort between gastroenterologists and surgeons is essential for addressing PFCD to achieve fistula closure and promote luminal healing. Limited fistula healing rates with conventional therapies have prompted the emergence of new biological agents, endoscopic procedures and surgical techniques that show promising results. Among these, mesenchymal stem cells injection is a particularly hopeful therapy. In addition to the burden of fistulas, individuals with perianal CD may face an increased risk of developing anal cancer. This underscores the importance of surveillance programmes and timely interventions to prevent late diagnoses and poor outcomes. Currently, there is no established formal anal screening programme. In this review, we provide an overview of the current state of the art in managing PFCD, including novel medical, endoscopic and surgical approaches. The discussion also focuses on the relevance of establishing an anal cancer screening programme in CD, intending to propose a risk-based surveillance algorithm. The validation of this surveillance programme would be a significant step forward in improving patient care and outcomes.
肛周疾病影响高达三分之一的克罗恩病(CD)患者,导致致残症状和生活质量显著下降,特别是对于那些患有肛周瘘管性 CD(PFCD)的患者。胃肠病学家和外科医生之间的合作对于治疗 PFCD 以实现瘘管闭合和促进管腔愈合至关重要。传统疗法的有限瘘管愈合率促使新的生物制剂、内镜程序和手术技术的出现,这些技术显示出有希望的结果。其中,间充质干细胞注射是一种特别有希望的治疗方法。除了瘘管的负担外,肛周 CD 患者可能面临更高的患肛门癌风险。这凸显了监测计划和及时干预的重要性,以防止晚期诊断和不良结局。目前,尚无既定的正式肛门筛查计划。在这篇综述中,我们概述了目前治疗 PFCD 的最新技术,包括新的医学、内镜和手术方法。讨论还侧重于在 CD 中建立肛门癌筛查计划的相关性,旨在提出基于风险的监测算法。验证这种监测方案将是改善患者护理和结局的重要一步。
