AIM:To determine the effectiveness of pancreatic duct (PD) stent placement for the prevention of pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP) in high risk patients.METHODS:Authors conducted a single-blind,randomized controlled trial to evaluate the effectiveness of a pancreatic spontaneous dislodgement stent against post-ERCP pancreatitis,including rates of spontaneous dislodgement and complications.Authors defined high risk patients as having any of the following:sphincter of Oddi dysfunction,difficult cannulation,prior history of post-ERCP pancreatitis,pre-cut sphincterotomy,pancreatic ductal biopsy,pancreatic sphincterotomy,intraductal ultrasonography,or a procedure time of more than 30 min.Patients were randomized to a stent group (n =60) or to a non-stent group (n =60).An abdominal radiograph was obtained daily to assess spontaneous stent dislodgement.Post-ERCP pancreatitis was diagnosed according to consensus criteria.RESULTS:The mean age (± standard deviation) was 67.4 ± 13.8 years and the male:female ratio was 68:52.In the stent group,the mean age was 66 ± 13years and the male:female ratio was 33:27,and in the non-stent group,the mean age was 68 ± 14 years and the male:female ratio was 35:25.There were no significant differences between groups with respect to age,gender,final diagnosis,or type of endoscopic intervention.The frequency of post-ERCP pancreatitis in PD stent and non-stent groups was 1.7％ (1/60) and 13.3％ (8/60),respectively.The severity of pancreatitis was mild in all cases.The frequency of post-ERCP pancreatitis in the stent group was significantly lower than in the non-stent group (P =0.032,Fisher's exact test).The rate of hyperamylasemia were 30％ (18/60) and 38.3％ (23 of 60) in the stent and non-stent groups,respectively (P =0.05,x2 test).The placement of a PD stent was successful in all 60 patients.The rate of spontaneous dislodgement by the third day was 96.7％ (58/60),and the median (range) time to dislodgement was 2.1 (2-3) d.The rates of stent migration,hemorrhage,perforation,infection (cholangitis or cholecystitis) or other complicationss were 0％ (0/60),0％ (0/60),0％ (0/60),0％ (0/60),0％ (0/60),respectively,in the stent group.Univariate analysis revealed no significant differences in high risk factors between the two groups.The pancreatic spontaneous dislodgement stent safely prevented post-ERCP pancreatitis in high risk patients.CONCLUSION:Pancreatic stent placement is a safe and effective technique to prevent post-ERCP pancreatitis.Therefore authors recommend pancreatic stent placement after ERCP in high risk patients.
