Seventy-five patients with malignant distal biliary obstruction were treated by percutaneously placed self-expandable Wallstent endoprostheses for palliative drainage. The stent diameter was 1 cm and its length 3.5-10.5 cm. Early complications occurred in 16 patients (21 per cent); they were related to the endoprosthesis in five (7 per cent) and serious in six (8 per cent). The 30-day mortality rate was 15 per cent, with a 1 per cent procedure-related mortality rate. Sixty-five patients died 6-365 (median 87) days after stent insertion and four had recurrence of obstruction after 21-341 (median 152) days. Reobstruction was the result of tumour ingrowth in one patient, angling of the stent in one and an unestablished cause in two. Ten patients were alive without obstruction 31-383 (median 65) days after stent insertion. Percutaneous use of the Wallstent endoprosthesis allows easy insertion; reobstruction is rare.
75例恶性远端胆管梗阻患者接受了经皮置入自膨式Wallstent内支架进行姑息性引流治疗。支架直径为1厘米，长度为3.5至10.5厘米。16例患者（21%）出现早期并发症；其中5例（7%）与内支架有关，6例（8%）较为严重。30天死亡率为15%，与手术相关的死亡率为1%。65例患者在支架置入后6至365天（中位值87天）死亡，4例在21至341天（中位值152天）后出现梗阻复发。再梗阻的原因分别为1例肿瘤长入、1例支架成角以及2例原因不明。10例患者在支架置入后31至383天（中位值65天）存活且无梗阻。经皮使用Wallstent内支架易于置入；再梗阻罕见。
