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.
