However, it remains challenging despite increased safety with treatment advances. The ideal power output and electrosurgical current mode for mucosal resection are not established. We aimed to identify the ideal electrical pulse for use during resection.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This pilot randomized, single\u2010blind, prospective, multicenter trial, recruited patients with ampullary adenomas and conventional anatomy who were scheduled to undergo endoscopic papillectomy. Endoscopic treatment was performed using a standardized algorithm and patients were randomized for endoscopic papillectomy with Endocut or Autocut. The primary outcome was the incidence of delayed bleeding. Incidence of procedure\u2010related pancreatitis, successful complete resection, pathological findings, and other adverse events were secondary endpoints.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Sixty patients were enrolled over a 2\u2010year period. The incidences of delayed bleeding (13.3% vs. 16.7%, <jats:italic>P<\/jats:italic>\u00a0=\u00a01.00) and pancreatitis (27% vs. 30%, <jats:italic>P<\/jats:italic>\u00a0=\u00a00.77) were similar between both groups. The rate of crush artifacts was higher in the Endocut than in the Autocut group (27% vs. 3.3%, <jats:italic>P<\/jats:italic>\u00a0=\u00a00.03). Immediate bleeding when resecting tumors greater than 14\u00a0mm in diameter was more common in the Autocut than in the Endocut group (88% vs. 46%, <jats:italic>P<\/jats:italic>\u00a0=\u00a00.04).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The Autocut and Endocut modes have similar efficacy and safety for endoscopic papillectomy.
