克罗恩病（Crohn's disease，CD）往往会导致肛周局部的病变，常见的肛周克罗恩病（perianal Crohn's disease，PCD）可表现为皮赘、痔、肛裂、溃疡、肛瘘、直肠阴道瘘、肛周脓肿、肛管直肠狭窄及恶性肿瘤。对于这些CD并发疾病的治疗应根据病人个体情况、医生的经验和判断，选择最恰当的治疗方式。大部分手术治疗应在避免有直肠炎症的情况下进行，将肛门失禁的风险最小化，同时避免直肠切除，提高病人的生活质量。

Abstract    Perianal lesions are common in patients with Crohn's disease (CD), which consist of anal skin tags, hemorrhoids, anal fissures and ulcers, perianal fistulas and abscesses, rectovaginal fistulas, anorectal strictures and carcinoma. The surgical management of perianal Crohn's disease (PCD) should be individualized for each patient and based on the surgeon’s experience and judgment. The management of PCD should avoid surgery when active rectal inflammation is present, treat other sites of active Crohn's disease with minimal risk of incontinence, avoidance of proctectomy, achieve remission ultimately and improve patients' quality of life.
