To assess the efficacy of the Wallstent endoprosthesis in malignant tracheobronchial obstruction.
Seven patients with irresectable carcinoma of the bronchus were treated with nine Wallstent endoprostheses. The procedures were performed under endoscopic and fluoroscopic guidance. Wallstent endoprostheses ranging from 8-16 mm in diameter and 26-49 mm in length were deployed after balloon dilatation of the strictures.
All stents were successfully deployed in the desired positions. There was one procedural complication and one procedure related death. Three patients showed significant improvement in respiratory status after stenting. At a mean follow-up of 5.1 months, there has been no stent migration, fracture, or collapse. One patient had proximal tumor overgrowth that was treated with additional stent insertion. One patient died after a bout of massive hemoptysis 3 months poststenting and it was difficult to tell whether this was related to the endoprosthesis.
The use of the Wallstent endoprosthesis in malignant tracheobronchial obstruction is technically feasible.
评估Wallstent内支架在恶性气管支气管梗阻中的疗效。
7例无法切除的支气管癌患者接受了9个Wallstent内支架治疗。手术在内镜和透视引导下进行。在对狭窄部位进行球囊扩张后，植入直径8 - 16毫米、长度26 - 49毫米的Wallstent内支架。
所有支架均成功植入预期位置。有1例手术并发症和1例与手术相关的死亡。3例患者在植入支架后呼吸状况有显著改善。平均随访5.1个月，未出现支架移位、断裂或塌陷。1例患者出现近端肿瘤过度生长，通过额外植入支架进行治疗。1例患者在植入支架3个月后因一次大量咯血死亡，难以确定这是否与内支架有关。
Wallstent内支架用于恶性气管支气管梗阻在技术上是可行的。
