Abstract
BACKGROUND & AIMS: Endoscopic stents are placed for palliation of extrahepatic bile duct obstruction. Although self-expandable metal stents (SEMS) remain patent longer than plastic stents, they are more expensive. We aimed to evaluate which type of stent (plastic, uncovered SEMS [uSEMS], or partially covered SEMS [pcSEMS]) is the most effective and we assessed costs. METHODS: We performed a multicenter randomized trial in 219 patients at 18 hospitals in The Netherlands from February 2008 through February 2013. Patients were assigned randomly for placement of a plastic stent (n = 73), uSEMS (n = 75), or pcSEMS (n = 71) during endoscopic retrograde cholangiopancreatography. Patients were followed up for up to 1 year. Researchers were not blinded to groups. The main study end points included functional stent time and costs. RESULTS: The mean functional stent times were 172 days for plastic stents, 288 days for uSEMS, and 299 days for pcSEMS (P < .005 for uSEMS and pcSEMS vs plastic). The initial placement of plastic stents ((sic)1042 or $1106) cost significantly less than placement of SEMS ((sic)1973 or $2094) (P = .001). However, the total cost per patient at the end of the follow-up period did not differ significantly between plastic stents ((sic)7320 or $7770) and SEMS ((sic)6932 or $7356) (P = .61). Furthermore, in patients with short survival times (<= 3 mo) or metastatic disease, the total cost per patient did not differ between plastic stents and SEMS. No differences in costs were found between pcSEMS and uSEMS. CONCLUSIONS: Although placement of SEMS (uncovered or partially covered) for palliation of extrahepatic bile duct obstruction initially is more
