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.
Design: Retrospective cohort study.
Setting: Academic hospital and a satellite surgery center.
Patients: A total of 362 consecutive patients referred for resection of large (≥20 mm) polyps in the colorectum.
Interventions: 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.
Main outcome measurements: 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).
Limitations: 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.
