ABSTRACT

Objective To investigate the role of temporary placement of fully covered self-expandable metal stent (cSEMS) for treatment of uncontrolled bleeding after endoscopic sphincterotomy (EST).Methods From January 2000 to present,a total of 3460 cases of EST were performed,and bleeding after the procedure was complicated in 29 (0.84％) of them,in which 4 could not to be stopped by conventional managements.Covered SEMSs were placed across the major papilla in these 4 patients.Results The stents were successfully placed and hemostasis was achieved in all patients.The stent was removed in 1 patient 1 week later,and spontaneous stent dislodgment occurred in 1 patient within 4 weeks.The other 2 patients rejected to remove the stents,and the patency maintained for more than 6 and 12 months respectively.No complication was observed in procedures of placing and removing stents.Conclusion Covered SEMS placement is a safe,effective and simple method for patients with uncontrolled bleeding after EST.
