BACKGROUND AND STUDY AIMS: Self-expandable metal stents (SEMS) are an effective palliative treatment for malignant biliary and duodenal strictures. Combined biliary and duodenal stenting remains a technical challenge, however. The aim of this study was to evaluate the technical feasibility of an endoscopic approach to double stenting of malignant biliary and duodenal strictures. PATIENTS AND METHODS: Consecutive patients referred for palliative gastroduodenal and biliary stenting were followed up prospectively. Patients' demographic characteristics, the site and nature of the strictures, success rates, complications, and survival time were recorded. RESULTS: A total of 64 patients underwent double stenting. In 46 patients, biliary obstruction occurred before the onset of duodenal obstruction (by a median of 107 days) (group 1); in 14 patients, biliary obstruction occurred concurrently with duodenal obstruction (group 2); and in four patients the duodenal obstruction preceded the biliary obstruction (by a median of 121 days) (group 3). The duodenal strictures were proximal to the papilla in 31 patients, adjacent to the papilla in 25 patients and distal to the papilla in eight patients. The majority of biliary strictures were in the middle or distal third of the bile duct (in 52/64 patients). Duodenal SEMS were successfully deployed in all patients. Combined endoscopic stenting was successful in 100% of patients in group 1, 86% of patients in group 2, and in 100% of patients in group 3. Taking the three groups together, early complications occurred in 6% of patients and late complications occurred in 16% of patients. The overall median survival after combined stenting was 81 days (range 2-447 days). CONCLUSIONS: Combined endoscopic biliary and duodenal SEMS insertion is safe and effective for palliation in malignant biliary and duodenal obstruction. Biliary stenting through the mesh of the duodenal SEMS is technically feasible and has a high success rate.
