• Background Self-expandable metal stents (SEMSs) are an effective palliative treatment for malignant biliary or duodenal strictures, but endoscopic stenting for combined malignant biliary and duodenal obstruction remains technically difficult. Objective To evaluate the feasibility and clinical success rate of endoscopic double stent-in-stent placement by using a new duodenal metallic stent for the management of malignant biliary and duodenal obstructions. Design Prospective, observational clinical feasibility study. Setting Tertiary referral center. Main Outcome Measurement Technical and clinical success, complications, midterm outcome. Patients and methods Eight patients with inoperable malignant biliary and duodenal strictures were enrolled. Endoscopic placement of a biliary SEMS was performed through the mesh of the duodenal stent. Results The duodenal strictures were in the first part of the duodenum in 3 patients (type 1) and in the second part in 5 patients (type 2). Duodenal stents were successfully deployed in all patients. Endoscopic placement of a biliary SEMS through the mesh of the duodenal stent was successful in 7 (87.5%) of 8 patients. In 2 of 3 patients with type 2 duodenal strictures with failed bile duct cannulation, biliary stenting was successful by using the rendezvous procedure. Early complications occurred in 1 patient. The overall median survival after combined stenting was 91 days (range 36–314 days). Limitations Small number of patients and no comparison with other enteral stents. Conclusions Biliary stenting through the new duodenal metallic stent is technically feasible and has a high success rate. Combined endoscopic biliary and duodenal stent-in-stent placement is a promising solution for the palliation of malignant biliary and duodenal obstruction.
