摘要: Self-expanding metal stents are claimed to prolong biliary-stent patency, although no formal comparative trial between plastic and expandable has been done. In a prospective randomised trial, we assigned 105 patients with irresectable distal bile-duct malignancy receive either stent (49) or straight polyethylene (56). Median patency of the first was significantly prolonged in compared those (273 vs 126 days; p = 0.006). The major cause dysfunction tumour ingrowth metal-stent group sludge deposition polyethylene-stent group. Treatment after any occlusion included placement stent. none 14 second occluded, whereas 11 23 (48%) clogged (p 0.002). Overall median survival 149 days did not differ treatment groups. Incremental cost-effectiveness analysis showed that initial results 28% decrease endoscopic procedures. have longer than offer adequate palliation malignant obstruction.
