Individualized management of upper rectal atresia.

Area of Science:

• Pediatric Surgery
• Neonatal Gastroenterology
• Congenital Malformations

Background:

• Congenital colonic atresia (CA) or stenosis is a rare cause of low intestinal obstruction in neonates.
• Management of CA depends on the atretic site and associated anomalies.
• This study focuses on the experience with upper rectal atresia.

Purpose of the Study:

• To report the clinical experience with upper rectal atresia over a 5-year period.
• To analyze clinical presentation, diagnosis, management, and outcomes.
• To evaluate surgical techniques for upper rectal atresia.

Main Methods:

• Retrospective analysis of 3 female newborns with upper rectal atresia treated between 2004 and 2008.
• Review of clinical presentation, diagnostic methods, associated anomalies, surgical techniques, and outcomes.
• Evaluation of contrast enema, laparotomy findings, and surgical procedures.

Main Results:

• All 3 patients presented with abdominal distension, bilious vomiting, and failure to pass meconium.
• Two patients showed upper rectal atresia on contrast enema; laparotomy confirmed Type III atresia in one.
• Surgical management included sigmoid colostomy, transanal mucosectomy, and pull-through procedures; one patient had associated jejunoileal atresias and imperforate anus with complications.

Conclusions:

• Upper rectal atresia is an uncommon condition requiring individualized surgical management.
• Transanal mucosectomy is a valuable technique for definitive pull-through procedures.
• Missed diagnosis of upper rectal atresia, especially with imperforate anus, can lead to delayed diagnosis and complications.
