Abstract

BACKGROUND/AIMS: A drug-eluting stent for unresectable malignant biliary obstruction was developed to increase stent patency by preventing tumor ingrowth. The safety and efficacy of a new generation of metallic stents covered with a paclitaxel-incorporated membrane using a Pluronic mixture (MSCPM-II) were compared prospectively with those of covered metal stents (CMSs) in patients with malignant biliary obstructions.

METHODS

This study was initially designed as a prospective randomized trial but was closed early because of a high incidence of early occlusion. Therefore, the data were analyzed using the intent-to-treat method. A total of 72 patients with unresectable distal malignant biliary obstructions were prospectively enrolled.

RESULTS

The two groups did not differ significantly in basic characteristics and mean follow-up period (MSCPM-II 194 days vs CMS 277 days, p=0.063). Stent occlusion occurred in 14 patients (35%) who received MSCPM-II and in seven patients (21.9%) who received CMSs. Stent patency and survival time did not significantly differ between the two groups (p=0.355 and p=0.570). The complications were mild and resolved by conservative management in both groups.

CONCLUSIONS

There were no significant differences in stent patency or patient survival in MSCPM-II and CMS patients with malignant biliary obstructions.

摘要

背景/目的:为提高支架通畅率、防止肿瘤长入,研发了一种用于不可切除恶性胆管梗阻的药物洗脱支架。将新一代含紫杉醇膜并使用普朗尼克混合物的金属支架(MSCPM-II)与覆盖金属支架(CMS)在恶性胆管梗阻患者中的安全性和有效性进行了前瞻性比较。

方法

本研究最初设计为前瞻性随机试验,但由于早期闭塞发生率高而提前终止。因此,采用意向性分析方法对数据进行分析。前瞻性纳入了72例不可切除的远端恶性胆管梗阻患者。

结果

两组患者的基本特征和平均随访时间无显著差异(MSCPM-II组194天,CMS组277天,p = 0.063)。接受MSCPM-II的患者中有14例(35%)发生支架闭塞,接受CMS的患者中有7例(21.9%)发生支架闭塞。两组间支架通畅率和生存时间无显著差异(p = 0.355和p = 0.570)。两组并发症均较轻,通过保守治疗得以缓解。

结论

MSCPM-II组和CMS组恶性胆管梗阻患者的支架通畅率或患者生存率无显著差异。
