Duodenal webs, a rare cause of infant intestinal blockage, may have a genetic link. This case highlights a family history, suggesting genetic counseling could aid early diagnosis.
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.
