Balloon esophageal dilatation offers many theoretical advantages (safety, speed, and patient comfort) over dilatation with mercury-filled bougies or with the Eder-Puestow system. The authors used balloon dilators in 22 patients with dysphagia secondary to benign or malignant strictures. Dilatation was performed with fluoroscopic guidance, blindly, or by a combination of these techniques. For "blind" stricture dilatation, an Eder-Puestow spring-tipped guide wire is placed into the stomach using a fiberoptic endoscope. The distance from the incisor teeth to the stricture is measured, and the balloon shaft is marked to indicate when the middle of the balloon is within the stricture. Dilatation is then performed using the antegrade or, the preferred, retrograde technique. Finally, the dilated stricture is calibrated by pulling an inflated balloon through the previously strictured area without difficulty. An attempt was made to achieve an esophageal diameter of 15 mm at the initial dilatation episode, and patient discomfort was used as a guide as to the final diameter. The balloon dilatation technique was highly successful, and a stricture diameter of 15 mm (45-47 French) was achieved at the initial dilatation in most instances. Malignant strictures were easily dilated. Balloon dilatation is convenient, effective, quick, and potentially safer than the previous Eder-Puestow or mercury-filled bougie techniques.
与使用汞柱式探条或埃德尔 - 普斯托系统进行扩张相比，球囊食管扩张术具有许多理论优势（安全性、速度和患者舒适度）。作者对22例因良性或恶性狭窄导致吞咽困难的患者使用了球囊扩张器。扩张在荧光透视引导下、盲目操作或结合这些技术进行。对于“盲目”的狭窄扩张，使用纤维内镜将埃德尔 - 普斯托弹簧头导丝置入胃内。测量从切牙到狭窄部位的距离，并在球囊轴上做标记，以指示球囊中部何时位于狭窄部位内。然后使用顺行技术或更常用的逆行技术进行扩张。最后，通过将充气的球囊顺利拉过先前狭窄的区域来校准扩张后的狭窄。在初次扩张时试图使食管直径达到15毫米，并以患者的不适感作为确定最终直径的指导。球囊扩张技术非常成功，在大多数情况下，初次扩张时狭窄直径就能达到15毫米（45 - 47法式）。恶性狭窄很容易被扩张。球囊扩张术比以前的埃德尔 - 普斯托或汞柱式探条技术更方便、有效、快捷且潜在安全性更高。
