Delayed bleeding was encountered in seven (9.6%) and 24 (32.9%) patients based on consensus guidelines and extended definitions, respectively. The incidence of pancreatitis was less frequent in the pre\u2010EP pancreatic stenting group than in the post\u2010EP pancreatic stenting group but statistically nonsignificant and underpowered (6.8 vs. 18.2%; <jats:italic>p<\/jats:italic>\u2009=\u20090.227, 95% confidence interval 0.046\u20134.030).
