本文报告在食管内置放一种新式树脂管以治疗食管良性或恶性狭窄。Celestin管长12.5cm,内径1cm,其下端呈环状突出,防止在置放后脱逸。患者须先经内窥镜检查,确定狭窄的部位和范围,测定剩余管腔的直径,并采取标本作活织组检查。第二步操作为置放Eder-Puestow引线。引线置放为进行安全扩张和插管的必要条件。引线放置方法可因病变范围和狭窄程度不同而异。在纤维内窥镜尚能通过狭窄部位时,可借
This article reports the placement of a new style of resin tube in the esophagus to treat benign or malignant esophageal stenosis. Celestin tube length of 12.5cm, an inner diameter of 1cm, the lower end of the annular protrusion, to prevent escape after placement. Patients must first endoscopic examination to determine the stenosis of the site and scope of the remaining lumen diameter measurement, and take specimens for living tissue examination. The second step is to place the Eder-Puestow lead. Lead placement is necessary for safe expansion and intubation.
