title: [Endoscopic polypectomy of colorectal adenomas: Monitoring patients in order to review the colonoscopic surveillance interval].
abstract: OBJECTIVE
  To determine the risk of advanced adenomas at surveillance colonoscopy after polipectomy. To review the colonoscopic surveillance interval and to compare the prevalence of adenomas in patients with low-risk and high-risk adenomas at screening colonoscopies.
  
  
  METHODS
  A cohort retrospective study. It was used a database of colonoscopies performed between 1999 and 2012. Seven hundred and sixty patients who had adenomas at first colonoscopy were included (465 males and 295 females, mean age 62 years old). They were divided into two groups: group A, low-risk adenomas, and group B, high-risk adenomas. In each group, it was compared the presence of adenomas in videocolonoscopies performed at 3 and 5 years.
  
  
  RESULTS
  At the first colonoscopy 409 patients (53.8%) belonged to group A and 351 (46.2%) than group B. In both groups the risk of new advanced adenomas in endoscopic surveillance at 5years was similar to the control at 3 years. Comparing both groups, the risk of new advanced adenomas in endoscopic surveillance at 3 years in group B was 1.96 times greater than in group A (P = 0.012).
  
  
  CONCLUSIONS
  At present, surveillance endoscopy is performed before the suggested interval. In both groups there were no statistically significant differences between surveillance control at 3 or 5 years. However, 62% of patients in group B have developed new advanced adenomas in endoscopic surveillance at 3 years. Therefore, it is recommended the endoscopic control with this interval.
