摘要

AIM To evaluate the efficacy of a newly developed dilator for endoscopic ultrasound(EUS)-guided drainage(ES Dilator).METHODS Fourteen consecutive patients who had undergone EUSguided choledochoduodenostomy(EUS-CDS) with the ES Dilator were identified from a prospectively maintained database and enrolled in the study group.Fourteen other patients who had undergone EUS-CDS without the dilator just prior to its introduction were analyzed as the control group.A historical cohort study was carried out comparing the two groups.The main outcome measurement was the procedure time.The technical success rate and early AE rate were also compared between the two groups.RESULTS There were no significant differences in age,sex and etiology of biliary obstruction.The utilization rate of a plastic stent was higher in the control group(36% vs 0%).The technical success rate was 100% in both groups.The mean procedure time was significantly shorter in the study group than in the control group(27 ± 7 min vs 44 ± 26 min,P = 0.026).Additionally,there were no patients who required more than 40 min for the procedure in the study group.Early adverse events occurred in 29%(4/14) of the control group whereas none in the study group.The adverse events in all 4 patients was bile peritonitis,including pan-peritonitis in one patient.All patientsrecovered with conservative treatment by medication.CONCLUSION The newly developed dilator was found to be useful for shortening procedure time and would prevent adverse events related to bile leakage in EUS-CDS.
