Abstract:
Objective:To investigate the safety and efficacy of using the self-designed C/S-J type self-releasing biliary stent for biliary drainage after endoscopic retrograde cholangiopancreatography(ERCP).Methods:A total of 184 patients with common bile duct stones admitted from October 2015 to October 2018 were allotted to three groups,and underwent ERCP and endoscopic sphincterotomy(EST)plus internal drainage with C/S-J type self-releasing biliary stent(C/S-J group,104 cases),ERCP and EST plus endoscopic nasobiliary drainage ENBD(ENBD group,40 cases),and ERCP and EST plus endoscopic retrograde biliary drainage(ERBD)(ERBD group,40 cases),respectively.The incidence rates of post-ERCP acute pancreatitis(PEP)and acute cholangitis among groups were compared,and the evacuation time of the self-releasing biliary stent in C/S-J group was observed.Results:There were no differences in sex,age,stone size,number of stones,previous cholecystectomy and presence or absence of cholangitis among the three groups(all P>0.05).In C/S-J group,ENBD group and ERBD group,the incidence rates of PEP were 6.73%(7/104),7.50%(3/40)and 10.00%(4/40),and the incidence rates of cholangitis were 0.96%(1/104),0.00%(0/40)and 2.50%(1/40)respectively,and the differences among groups showed no significance(both P>0.05).In C/S-J group,the stent in two cases was shed and evacuated on the first day after ERCP,the stent in one case failed to evacuate 3 months after ERCP and then was removed with duodenoscope,and the stent in the remaining cases evacuated through the digestive tract within 9-14 d with an average of 10.2 d after ERCP,and no complications such as obstruction,perforation and bleeding of the digestive tract occurred.Conclusion:Using the self-designed C/S-J type self-releasing biliary stent for post-ERCP biliary drainage is safe and effective,and it also can overcome the limitations of ENBD and ERBD.
