Insights
An imperforate anus (ARM) rarely occurs with a Bochdalek diaphragmatic hernia. This case highlights a delayed diaphragmatic hernia presentation 10 months post-ARM surgery, an uncommon congenital abnormality association.
Area of Science:
- Pediatric Surgery
- Neonatalogy
- Congenital Malformations
Background:
- Imperforate anus (ARM) is often associated with VACTERL anomalies.
- Congenital diaphragmatic hernias (CDH) are also linked to other birth defects.
- The simultaneous occurrence of ARM and CDH is uncommon.
Observation:
- A case report of an infant with ARM and a Bochdalek type diaphragmatic hernia is presented.
- The diaphragmatic hernia had a delayed presentation, occurring 10 months after surgical repair of the ARM.
- This specific combination of congenital abnormalities is rare in clinical practice.
Findings:
- The study details an unusual presentation of a right-sided Bochdalek type diaphragmatic hernia in an infant with a pre-existing anorectal malformation.
- The diaphragmatic hernia was diagnosed significantly later than the initial anorectal malformation repair.
- This case underscores the complex and sometimes delayed manifestation of congenital anomalies.
Implications:
- Highlights the importance of considering associated anomalies in patients with imperforate anus, even with delayed presentations.
- Suggests the need for vigilance in diagnosing diaphragmatic hernias in infants with complex congenital conditions.
- Contributes to the understanding of rare co-occurrences of congenital malformations, aiding future diagnostic and management strategies.
Abstract:
Patients with an imperforate anus frequently present with congenital abnormalities, most commonly as a component of VACTERL (Vertebral anomalies, Anorectal malformations, Cardiac defect, Tracheo-Oesophageal fistula and Oesophageal atresia, Renal anomalies, and Limb defects) anomalies. It is, however, unusual for infants to present with a concurrent anorectal malformation (ARM) and a Bochdalek type diaphragmatic hernia. We describe an infant with an ARM and a delayed presentation of a right-sided Bochdalek type diaphragmatic hernia. In this case, the Bochdalek type diaphragmatic hernia presented 10 months after a laparoscopic-assisted anorectal plasty was performed. Despite both ARM and congenital diaphragmatic hernia known to be associated with other congenital malformations, the association of these particular congenital abnormalities in an individual patient is uncommon.
