To overcome the drawbacks of the modified Gianturco stent tube with barbs, a new barbless stent tube was constructed. Twenty-two barbless stent tubes 4.5-14.0 cm long were placed with a new introducing tube in 21 patients: 10 stent tubes in 10 patients with recurrent dysphagia after radiation therapy or chemotherapy, 10 in 10 patients with esophageal cancer in whom surgical management was contraindicated, and two in one patient with postoperative benign stricture. No technical failure or procedural complications occurred. After the procedure, all but two patients could ingest most or all foods. In two patients with an esophagorespiratory fistula and one patient with esophageal rupture, the barbless stent tube successfully occluded the fistula and rupture site. The stent tube migrated in one patient. Fifteen patients are surviving, with the stent tubes patent for 3-35 weeks (mean patency, 13 weeks); the six other patients died 7-24 weeks (mean, 16 weeks) after stent placement. It is concluded that barbless stent tubes show promise in the management of dysphagia caused by esophageal strictures.
为克服带倒刺改良型Gianturco支架管的缺点，构建了一种新型无倒刺支架管。使用新型导入管将22根长度为4.5至14.0厘米的无倒刺支架管置入21例患者体内：10例接受过放疗或化疗后复发性吞咽困难的患者置入10根支架管，10例手术治疗禁忌的食管癌患者置入10根，1例术后良性狭窄患者置入2根。未发生技术失败或操作并发症。术后，除2例患者外，其余患者均可摄入大部分或全部食物。2例食管气管瘘患者和1例食管破裂患者中，无倒刺支架管成功封堵了瘘口和破裂部位。1例患者出现支架管移位。15例患者存活，支架管通畅3至35周（平均通畅时间为13周）；其他6例患者在支架置入后7至24周（平均16周）死亡。结论是，无倒刺支架管在治疗食管狭窄所致吞咽困难方面显示出前景。
