We evaluated the association between stent type (SEMS vs PS) and PEP in malignant and benign biliary obstructions.<\/jats:p><jats:p>\n          Results\u2002Among the 1136 patients included in our study, 399 had SEMS placed and 737 had PS placed. Patients with PS were more likely to have pancreatic duct cannulation, pancreatic duct stent placement, double guidewire technique, sphincterotomy and sphincteroplasty as compared to the SEMS group.\u200aOn multivariate analysis, PEP rates were higher in the SEMS group (8.0\u200a%) versus the PS group (4.8\u200a%) (OR 2.27 [CI, 1.22, 4.24]) for all obstructions. For malignant obstructions, PEP rates were 7.8\u200a% and 6.6\u200a% for SEMS and plastic stents, respectively (OR 1.54 [CI, 0.72, 3.30]). For benign obstructions the PEP rate was higher in the SEMS group (8.8\u200a%) compared to the PS group (4.2\u200a%) (OR 3.67 [CI, 1.50, 8.97]). No significant differences between PEP severity were identified based on stent type when stratified based on benign and malignant.<\/jats:p><jats:p>\n          Conclusions\u2002PEP rates were higher when SEMS were used for benign obstruction as compared to PS.
