We thank Lv et  al1 for their interest and comments in our study. Underwater endoscopic mucosal resection (UEMR) is recently getting attention for its efficacy and safety for treatment of superficial nonampullary duodenal epithelial tumor (SNADET). Usefulness of UEMR for SNADET had been reported in several report s; however, previous studies had small sample size without evaluation of clinically relevant end points.2,3 Thus, we conducted a multicenter prospective study to evaluate the nonrecurrence rate of UEMR for SNADET using careful follow-up biopsy.
