Most newborns with imperforate anus, except for those with very low varieties, undergo a diverting colostomy performed in the postnatal period, with definitive surgical repair at a later age. Accurate demonstration of the anatomy of any associated fistula between the rectum and urogenital tract is essential for optimal surgical management. An augmented-pressure distal segment colostogram is recommended prior to definitive repair, both to confirm the level of rectal atresia and to define any associated fistulous communication. We report a case of high imperforate anus with rectourethral fistula in which the fistulous tract was not identified on the conventional contrast colostogram but was readily delineated when an augmented-pressure modification of the technique was utilized. The technical aspects of augmented-pressure colostography are presented.
大多数肛门闭锁的新生儿，除了那些病变程度非常低的，在出生后会接受转流性结肠造口术，并在稍大年龄进行确定性手术修复。准确显示直肠与泌尿生殖道之间任何相关瘘管的解剖结构对于优化手术管理至关重要。在进行确定性修复之前，建议进行增强压力的远端结肠造口造影，以确认直肠闭锁的水平并确定任何相关的瘘管连通情况。我们报告一例高位肛门闭锁合并直肠尿道瘘的病例，在传统的对比结肠造口造影中未发现瘘管，但在采用该技术的增强压力改良方法时很容易显示出来。本文介绍了增强压力结肠造口造影的技术要点。
