Duodenal Duplication Cysts in Children: Clinical Features and Current Treatment Choices

Background: Duodenal duplication cysts are rare gastrointestinal tract malformations. Most patients experience symptom onset in the first decade of life. This review aims to examine clinical presentation, management strategies and outcomes of duodenal duplication cysts in childhood. Methods: A Pubmed/Medline (http://www.ncbi.nlm.nih.gov/pubmed/) search in October 2019 for articles published since 1999 using the keywords "duodenal duplication cyst," "child" and "newborn" was carried out. Clinical symptoms, complications, diagnostic examinations, treatment options and outcomes were analyzed and tabulated. Results: There were 41 citations in the literature providing adequate descriptions of 45 cases of duodenal duplication cysts. The age of presentation ranged from newborn to 18 years. The median interval between initial presentation and definitive diagnosis and treatment was 17 months (range: 2 months to 12 years). Overall, 67% of cases presented with abdominal pain, and 43% were complicated with pancreatitis. Different surgical and endoscopic therapeutic strategies were reported. Conclusions: Duodenal duplication cysts may be associated with life-threatening complications and/or recurrent symptoms, impairing quality of life. Early recognition of patients who demonstrate suggestive signs and symptoms is important to ensure success of treatment. This review may be useful to highlight the main diagnostic aspects and limit the risk of a delayed diagnosis.
