Familial multiple jejunal atresia with malrotation

Area of Science:

• Pediatric Surgery
• Gastroenterology
• Medical Genetics

Background:

• Midgut malrotation and jejunal atresia are significant congenital gastrointestinal anomalies.
• Jejunal atresia involves a blockage in the small intestine, while malrotation is an abnormal positioning of the intestines.
• These conditions can lead to severe feeding difficulties and surgical emergencies in neonates.

Observation:

• The report details two siblings presenting with multiple jejunal atresias and malrotation of the midgut.
• The first sibling had incomplete gut rotation with two jejunal atresias and an intraluminal diaphragm.
• The second sibling exhibited complete failure of gut rotation, two jejunal atresias, and a V-shaped mesenteric defect.

Findings:

• This is the first reported instance of familial, multi-level small intestinal atresias associated with malrotation.
• The co-occurrence of these anomalies in siblings suggests a potential genetic etiology.
• Specific malformations included intraluminal diaphragms and mesenteric defects.

Implications:

• Understanding the genetic basis of this familial association is crucial for genetic counseling and risk assessment.
• Further research into the molecular mechanisms underlying combined jejunal atresia and malrotation is warranted.
• This case highlights the importance of considering familial patterns in congenital gastrointestinal anomalies.
