Fifty-two patients in nine Austrian hospitals were treated with biliary self-expanding metal endoprostheses (Wallstents) for malignant biliary obstruction, and followed up retrospectively using questionnaires, answered by the endoscopists. Stent placement was successful in all patients. The technical failure rate at the first attempt was 7.7%, and stenting-associated mortality was 3.8% due to mispositioning of stents, leading in two cases to death. The 30-day mortality was 13.5%, and early complications occurred in 15.4%. The median survival was 216 days, and the median stent patency was 291 days. During follow-up, stent occlusion was observed in ten patients, acute cholangitis in 12 patients, acute pancreatitis in three patients, acute cholecystitis in one patient, and duodenal ulceration due to stent erosion in one patient. Routine use of biliary self-expanding metal endoprostheses by averagely experienced endoscopists can be recommended. Attention has to be paid to the correct placement of the guidewire and stent.
奥地利九家医院的52例患者接受了胆道自膨式金属内支架（Wallstents）治疗恶性胆道梗阻，并通过内镜医师填写的问卷进行回顾性随访。所有患者支架置入均成功。首次尝试的技术失败率为7.7%，因支架位置不当导致的支架置入相关死亡率为3.8%，导致两例死亡。30天死亡率为13.5%，早期并发症发生率为15.4%。中位生存期为216天，中位支架通畅时间为291天。随访期间，观察到10例患者支架堵塞，12例患者发生急性胆管炎，3例患者发生急性胰腺炎，1例患者发生急性胆囊炎，1例患者因支架侵蚀导致十二指肠溃疡。推荐经验一般的内镜医师常规使用胆道自膨式金属内支架。必须注意导丝和支架的正确放置。
