Anorectal Malformations

Background:

Congenital funnel anus is a rare anorectal malformation.
It is infrequently encountered, representing 3.5% of low anorectal malformations at a specialized center.
This condition is distinct from typical low anorectal anomalies.

Observation:

Five patients (three children, two adults) with congenital funnel anus were analyzed.
All patients exhibited a significant megacolon.
Constipation was severe and unresponsive to conservative management.

Findings:

Surgical resection of the dilated colon segment was performed.
A low coloanal anastomosis was created in all cases.
This surgical approach successfully alleviated severe constipation in every patient.

Implications:

Congenital funnel anus is strongly associated with megacolon and refractory constipation.
Surgical management offers a definitive solution for constipation in these patients.
This approach may improve outcomes for individuals with this rare anomaly.
