    Abstract:
    BACKGROUND AND AIM: The presence of perianal disease in Crohn's disease patients is one of the factors of postoperative recurrence. The aim of this study is to evaluate long-term prognosis of perianal Crohn's disease patients in Asian. METHODS: Patients with Crohn's disease who had undergone surgical bowel resection were divided into two groups according to the presence of perianal lesion. We monitored the occurrences of abdominal and/or perianal reoperation and readmission due to disease flare-up. RESULTS: The 132 patients included in the study were divided into 2 groups, those with perianal disease (45 patients, 34.1%) and those without perianal disease (87 patients, 65.9%). Patients with perianal disease was younger in age (33.8 years versus 39.8 years, p = 0.015) and had been diagnosed as CD at a younger age (21.9 years versus 28.6 years, p = 0.005) than patients without perianal disease. Patients with perianal disease showed more extra-intestinal manifestation than patients without perianal disease (8 versus 3, p = 0.008). Reoperation was required in 46 (44.8%) patients during the follow-up period. The presence of perianal disease independently increased the risk of reoperation [hazard ratio (HR), 3.112; confidence interval (CI), 1.707-5.675]. Furthermore, patients with perianal disease had increasing risks of abdominal reoperation (HR 1.978; 95% CI, 1.034-3.784). CONCLUSIONS: Patients with Crohn's disease and perianal lesions had a higher risk of reoperation. Considering these findings, physicians should consider aggressive and early top down therapy for patients with perianal Crohn's disease.
