Imperforate anus associated with a recto-bulbar-cutaneous fistula

Area of Science:

• Pediatric Surgery
• Congenital Malformations
• Urology

Background:

• Imperforate anus is a congenital condition affecting the terminal part of the gastrointestinal tract.
• Rectocutaneous fistulas are abnormal tracts connecting the rectum to the skin, often associated with anorectal malformations.
• Complex fistulas involving the genitourinary system present unique diagnostic and surgical challenges.

Observation:

• Two cases of newborn males presented with imperforate anus.
• A long rectocutaneous fistula was noted, extending deeply into the scrotum.
• The fistula communicated with the bulbar urethra in its midportion.

Findings:

• The described anatomy represents a rare and complex variant of anorectal malformations.
• Comparison with a similar reported case suggests potential patterns in embryological development.
• Speculations on the embryogenesis of this specific fistulous tract are discussed.

Implications:

• Accurate diagnosis and understanding of complex fistulas are crucial for appropriate surgical management.
• Further research into the embryogenesis of these anomalies may improve prediction and prevention strategies.
• This case report contributes to the literature on rare genitourinary and anorectal malformations in newborns.
