BACKGROUND/AIMS: Surveillance of individuals with colon polyps is important for the prevention of colon cancer, and its interval is based on the clinical status. Our aims were to determine the recurrence rate of advanced polyp after polypectomy and estimate the adequate interval of surveillance colonoscopy as well as the risk factors of recurrence in Korea.
Ninety-seven patients who underwent follow-up colonoscopy after initial colonoscopic polypectomy were retrospectively studied. All polyps were endoscopically removed with electrocautery.
Mean number of initial polyps were 2.2 and advanced polyps were observed in 40% of the patients. The cumulative recurrence rate of colon polyp was 13.8% within 1 year, and 60% within 3 years, while that of advanced polyps was 2.5% and 31% within 1 and 3 years, respectively. The significant difference was noted according to the initial polyp number in both overall and advanced polyp recurrence rate. The age at the diagnosis of colon polyps was a significant factor only in overall polyp recurrence rate. Patients who initially had one polyp showed 15% of advanced polyp recurrence within 3 years.
Recurrence of advanced polyp is very rare within one year after polypectomy. Patients with single polyp have low risk and thus, their surveillance may be delayed beyond the standard 3 years. When surveillance colonoscopy is to be performed for the patients with 2 or more polyps, initial polyp number and age should be considered.
背景/目的：对结肠息肉患者进行监测对于预防结肠癌很重要，其监测间隔基于临床状况。我们的目的是确定息肉切除术后高级别息肉的复发率，估计监测结肠镜检查的合适间隔以及韩国复发的危险因素。
回顾性研究了97例在初次结肠镜息肉切除术后接受随访结肠镜检查的患者。所有息肉均通过电灼在内镜下切除。
初始息肉的平均数量为2.2个，40%的患者观察到高级别息肉。结肠息肉的累积复发率在1年内为13.8%，3年内为60%，而高级别息肉在1年和3年内的复发率分别为2.5%和31%。总体和高级别息肉复发率根据初始息肉数量存在显著差异。结肠息肉诊断时的年龄仅在总体息肉复发率中是一个显著因素。最初有一个息肉的患者在3年内高级别息肉复发率为15%。
高级别息肉在息肉切除术后1年内复发非常罕见。单个息肉患者风险较低，因此，他们的监测可以推迟到标准的3年之后。当对有2个或更多息肉的患者进行监测结肠镜检查时，应考虑初始息肉数量和年龄。
