改良型Y型自膨胀式金属内支架治疗五例残胃-空肠吻合口狭窄

Implantation of modified Y-shaped self-expandable stent for the treatment of stenosis of gastroenteric stoma:preliminary results in five cases

目的探讨改良型Y型一体化自膨胀式金属内支架治疗残胃-空肠吻合口狭窄的可行性和疗效。方法根据残胃-空肠吻合口狭窄的特殊解剖结构与病变特点,自行设计改良型Y型一体化自膨胀式金属内支架。X线监视下,对5例残胃-空肠吻合口狭窄患者置入5枚改良型Y型一体化内支架。结果内支架均一次置入成功,所有患者置入内支架后恶心、呕吐及腹胀缓解,生活质量提高。结论改良型Y型一体化自膨胀式胃肠道金属内支架能够一次性解除残胃-空肠吻合口区域狭窄,技术可行,近期疗效可靠,值得进一步推广应用。

Objective To investigate the feasibility and therapeutic effect of stenting therapy by using modified Y-shaped self-expandable metal stent for the stenosis of gastroenteric stoma. Methods According to the particular anatomic structures and the pathological features of the narrowed gastroenteric stoma,the authors designed a modified Y-shaped self-expandable metal stent. Under the fluoroscopic guidance,implantation of modified Y-shaped self-expandable metal stent was performed in 5 patients with narrowed gastroenteric stoma. The technical safety and the clinical results were evaluated. Results The modified Y-shaped self-expandable metal stent was successfully implanted with one procedure in all five patients. After the implantation the symptoms such as nausea,vomiting,abdominal distension were promptly relieved,and the patients＇ living quality was markedly improved. Conclusion The stenting therapy with modified Y-shaped self-expandable metal stent can rapidly relieve the stenosis of gastroenteric stoma once for all. The technique is feasible and the short-term effect is reliable,therefore,it is worth popularizing this therapy in clinical practice.
