Enteric duplication cyst

Enteric duplication cysts, sometimes simply called duplication cysts, are rare congenital malformations of the gastrointestinal tract. They most frequently occur in the small intestine, particularly the ileum, but can occur anywhere along the gastrointestinal tract. They may be cystic or tubular in conformation. Enteric duplication cysts, sometimes simply called duplication cysts, are rare congenital malformations of the gastrointestinal tract. They most frequently occur in the small intestine, particularly the ileum, but can occur anywhere along the gastrointestinal tract. They may be cystic or tubular in conformation. The condition of having duplication cysts has been called intestinal duplication. Symptoms depend on the location of the duplication. Duplications occurring high in the gastrointestinal tract (e.g. esophageal) may cause difficulty breathing due to compression of the airway. Lower gastrointestinal duplications (e.g. duodenum, colon) can be associated with abdominal pain, gastrointestinal bleeding, a palpable mass, vomiting, or may cause bowel obstruction. Smaller lesions can act as a so-called 'lead point' for intussusception.
