[Congenital H-type anorectal fistula: two case reports]

Area of Science:

• Pediatric Surgery
• Anorectal Malformations
• Urology

Background:

• Congenital H-type fistula is an extremely rare anorectal anomaly without anal atresia, involving a connection between the anorectum and the urogenital tract.
• This condition presents unique diagnostic and management challenges in pediatric surgical practice.

Observation:

• The study reports on two young female patients diagnosed with congenital H-type fistulas.
• The fistula connected the left labium/vulva to the anus, presenting as a rare variant of anorectal malformations.

Findings:

• Following initial management of local infection and abscess, both patients underwent anterior sagittal anorectovaginoplasty (ASARVP).
• Post-operative follow-up revealed no recurrence of the fistula or abscess in either patient, indicating successful surgical intervention.

Implications:

• Anterior sagittal anorectovaginoplasty (ASARVP) is presented as a simple and effective surgical method for treating congenital H-type fistulas.
• The procedure yielded excellent functional and anatomical outcomes, offering a promising treatment option for this rare condition.
