A new anatomic variant of an anorectal malformation resembling an H-type fistula was observed in a newborn girl. This variant consisted of a high-grade stenosis of the anal canal below the level of the levator muscle with a blind-ending fistulous tract originating from the stenotic segment and running toward the posterior wall of the vestibulum. The embryogenesis of this malformation remains to be seen.
在一名新生女婴中观察到一种类似H型瘘管的肛门直肠畸形的新解剖变异。这种变异包括肛提肌水平以下肛管的高度狭窄，伴有一个盲端瘘管，起源于狭窄段并通向处女膜后壁。这种畸形的胚胎发生情况尚待观察。
