title: Recurrence rates after EMR of large sessile serrated polyps.
abstract: BACKGROUND
  Little is known regarding the recurrence rate after EMR of large (≥20 mm) sessile serrated adenoma/polyps (SSA/Ps).
  
  
  OBJECTIVE
  To compare the recurrence rate among SSA/Ps and conventional adenomas in patients referred to a specialty practice for EMR.
  
  
  METHODS
  Retrospective cohort study.
  
  
  METHODS
  Academic hospital and a satellite surgery center.
  
  
  METHODS
  A total of 362 consecutive patients referred for resection of large (≥20 mm) polyps in the colorectum.
  
  
  METHODS
  All EMRs were performed with a submucosal contrast agent. All subjects had a follow-up surveillance examination (inspection and biopsy of the EMR) at our center.
  
  
  METHODS
  Rates of residual polyp at follow-up examination.
  
  
  RESULTS
  Residual polyp was identified among 8.7% of SSA/Ps compared with 11.1% for conventional adenomas (P = .8).
  
  
  CONCLUSIONS
  Retrospective design, procedures performed by a single experienced endoscopist, low number of serrated lesions.
  
  
  CONCLUSIONS
  The rate of recurrence after EMR of SSA/Ps is similar to the rate after EMR of conventional adenomas.
