Heterotopic pancreas causing duodenal obstruction in a patient previously treated for choledochal cyst

Area of Science:

• Pediatric Surgery
• Gastroenterology
• Developmental Biology

Background:

• Choledochal cysts are congenital dilations of the bile ducts, commonly presenting in childhood.
• Heterotopic pancreas, or ectopic pancreatic tissue, can occur throughout the gastrointestinal tract, including the duodenum.
• While both conditions are known in pediatric populations, their simultaneous presentation is exceptionally uncommon.

Observation:

• A 9-year-old male patient experienced duodenal obstruction due to a pancreatic rest (heterotopic pancreas).
• The patient had a history of choledochal cyst treated surgically at 4 months of age.
• This presentation marks a metachronous occurrence of both conditions in the same individual.

Findings:

• The duodenal pancreatic rest caused significant obstruction requiring surgical management.
• The case confirms the possibility, though extreme rarity, of a child having both a history of choledochal cyst and a heterotopic pancreas presenting later in life.
• Surgical intervention was successful in relieving the obstruction.

Implications:

• This case expands the understanding of rare congenital anomalies in children.
• It emphasizes the importance of considering diverse gastrointestinal pathologies in pediatric patients with complex medical histories.
• Further research into the embryological origins and potential links between these two conditions may be warranted.
