Given the chronic nature of mucosal inflammation present in patients with inflammatory bowel disease (IBD), there is a high risk of dysplastic lesions progressing to cancer, in addition to a high risk of synchronous and/or metachronous cancers developing in those diagnosed with dysplasia. Due to this, consensus guidelines recommend regular surveillance. When visible dysplasia is encountered, options include endoscopic or surgical resection depending on characteristics of the lesion. Advancements in endoscopic tools increasingly allow for endoscopic removal when appropriate. Invisible dysplasia discovered on random biopsy should prompt referral to physicians who specialize in IBD. While surgical resection with proctocolectomy significantly decreases the risk of colorectal cancer, the risk must be balanced against the morbidity of surgery and quality-of-life concerns. Management of dysplasia in IBD patients requires complex decision-making that requires balance of patient values and goals of care with cancer-related risk factors.
鉴于炎症性肠病(IBD)患者存在慢性黏膜炎症,发育异常病变进展为癌症的风险很高,此外,已诊断为发育异常的患者发生同时性和/或异时性癌症的风险也很高。因此,共识指南建议进行定期监测。当遇到可见的发育异常时,可根据病变特征选择内镜切除或手术切除。内镜工具的进步越来越允许在适当的时候进行内镜切除。随机活检发现的隐匿性发育异常应促使转诊给IBD专科医生。虽然全直肠结肠切除术可显著降低结直肠癌风险,但必须在手术风险与生活质量问题之间进行权衡。IBD患者发育异常的管理需要复杂的决策,这需要平衡患者的价值观和护理目标以及癌症相关风险因素。
