Anorectal malformations

Area of Science:

• Pediatric Surgery
• Developmental Biology
• Medical Genetics

Background:

• Anorectal malformations (ARM) are congenital anomalies affecting the anus and rectum, with a prevalence of 3.32 per 10,000 pregnancies.
• These malformations represent a spectrum of developmental defects originating from aberrant hindgut septation during early gestation.
• While some cases are linked to genetic syndromes, the etiology of most non-syndromic ARM remains unclear.

Purpose of the Study:

• To review the current understanding of Anorectal Malformations (ARM).
• To highlight diagnostic challenges and current surgical management.
• To emphasize the need for improved outcomes and further research.

Main Methods:

• Clinical diagnosis based on perineal inspection.
• Review of surgical techniques, including posterior sagittal anorectoplasty and minimally invasive approaches.
• Analysis of current outcomes and recognized needs for improvement.

Main Results:

• ARM diagnosis is typically made postnatally; prenatal detection remains limited.
• Posterior sagittal anorectoplasty is the standard surgical repair, with evolving minimally invasive adaptations.
• Functional outcomes and quality of life require further enhancement.

Conclusions:

• Continued research is essential to improve prenatal diagnosis of ARM.
• Elucidating genetic and epigenetic factors is crucial for understanding ARM etiology.
• Optimizing surgical procedures and addressing psychosocial aspects are vital for improving patient care.
