One particular form of an anorectal malformation--the anterior perineal anus--is frequently overlooked in the neonate period because defecation is easy at this age. However, with the change of diet, this malformation as a rule leads to chronic constipation. The lateral view at the beginning of an irrigoscopy usually shows a characteristic picture of a horizontal caudal limitation of the rectum, a dorsal pouch, a beakshaped fistula and an elevation of the anorectal transition. These findings contribute essentially to the clinical diagnosis and permit early operation.
一种特殊类型的肛肠畸形——会阴前肛门畸形——在新生儿期常被忽视，因为这个年龄段排便容易。然而，随着饮食的改变，这种畸形通常会导致慢性便秘。灌肠造影开始时的侧位片通常显示出直肠尾端水平受限、背侧盲袋、喙状瘘管以及肛肠移行部抬高的特征性影像。这些表现对临床诊断至关重要，有助于早期手术。
