Familial congenital duodenal obstruction

Area of Science:

• Pediatric Surgery
• Medical Genetics
• Embryology

Background:

• Duodenal webs cause congenital duodenal stenosis due to incomplete embryonic bowel recanalization.
• Symptoms like bilious vomiting in infants necessitate prompt surgical intervention for favorable outcomes.
• Familial predisposition for duodenal webs is not well-documented in medical literature.

Purpose of the Study:

• To report a rare case of a duodenal web and concurrent annular pancreas in an infant.
• To investigate the potential familial occurrence of congenital duodenal obstruction.
• To emphasize the importance of family history in diagnosing and managing duodenal webs.

Main Methods:

• Case report of an infant diagnosed with a duodenal web and annular pancreas.
• Review of the infant's family history, revealing a father with congenital duodenal obstruction.
• Discussion of embryological development and genetic factors in duodenal anomalies.

Main Results:

• The infant presented with symptoms consistent with duodenal obstruction.
• A positive family history of congenital duodenal obstruction was identified in the infant's father.
• The co-occurrence of duodenal web and annular pancreas was noted.

Conclusions:

• Familial occurrence of duodenal webs, though uncommon, should be considered in diagnosis.
• Early diagnosis can be facilitated by recognizing potential familial predispositions.
• Preconception genetic counseling may benefit parents with a history of congenital duodenal obstruction.
