The aim of our study is to compare the efficacy and safety of "outlet-shape" tailored stents with standard stents for the management of distal gastric cancer causing gastric outlet obstructions (GOOs) with varying gastric cavity shapes and sizes. To determine the shape and size of the GOOs, stomach opacifications were performed using contrast media before stenting. Two basic shapes of the residual cavity of the proximal GOO were observed: cup shaped or approximately cup shaped and funnel shaped or approximately funnel shaped. Other shapes were not found. In the GOO tailored group, the size and shape of the proximal ends of the tailored stent were suited for the residual cavity of the proximal GOO. The tailored stents included large cup-shaped stents and large funnel-shaped stents. GOO tailored covered stents led to less restenosis and reintervention rates compared to standard uncovered stents but with the same survival.
我们研究的目的是比较“出口形状”定制支架与标准支架在治疗因胃腔形状和大小各异而导致胃出口梗阻（GOO）的远端胃癌方面的疗效和安全性。为确定GOO的形状和大小，在置入支架前使用造影剂对胃部进行造影。观察到近端GOO残余腔的两种基本形状：杯状或近似杯状以及漏斗状或近似漏斗状。未发现其他形状。在GOO定制组中，定制支架近端的大小和形状适合近端GOO的残余腔。定制支架包括大杯状支架和大漏斗状支架。与标准无覆膜支架相比，GOO定制覆膜支架导致的再狭窄和再次干预率更低，但生存率相同。
