目的 探讨胰腺假性囊肿行内引流治疗的临床效果。方法 对我院2001年1月至2008年12月期间收治的20例胰腺假性囊肿行内引流治疗的临床资料进行回顾性分析。结果 本组20例中行囊肿与胃吻合7例,囊肿与空肠Roux-en-Y吻合13例。14例获得3个月~6年(平均32个月)随访,均获一次性治愈,无近、远期并发症发生。结论 根据囊肿形成的大小和时间选择恰当的内引流治疗方式,能有效治愈胰腺假性囊肿。
To explore the influence of bionic texture coronary stents on hemodynamics, a type of bioabsorbable polylactic acid coronary stents was designed, for which a finite element analysis method was used to carry out simulation analysis on blood flow field after the implantation of bionic texture stents with three different shapes (rectangle, triangle and trapezoid), thus revealing the influence of groove shape and size on hemodynamics, and identifying the optimal solution of bionic texture groove. The results showed that the influence of bionic texture grooves of different shapes and sizes on the lower wall shear stress region had a certain regularity. Specifically, the improvement effect of grooves above 0.06 mm on blood flow characteristics was poor, and the effect of grooves below 0.06 mm was good. Furthermore, the smaller the size is, the better the improvement effect is, and the 0.02 mm triangular groove had the best improvement effect. Based on the results of this study, it is expected that bionic texture stents have provided a new method for reducing in-stent restenosis.
