Perforated Enteric Duplication Cyst in Adulthood: An Uncommon Etiology of Acute Abdomen Requiring Urgent Surgical Intervention

Enteric duplication cysts (EDCs) represent rare congenital anomalies of the gastrointestinal tract (GIT), with an estimated incidence of approximately 1 in 4,500 live births, occurring in 0.2% of the pediatric population with a slight male predilection (Schalamon et al., 2000). While most prevalent in the ileum (33%), followed by the esophagus (20%) and colon (13%), their presentation in adulthood is exceptionally uncommon. These foregut- or midgut-derived lesions are characterized by an epithelial lining, smooth muscle layers in their wall, and an intimate association with the alimentary tract. This report details a rare case of a perforated jejunal EDC in an adult male (Nebot et al., 2018), highlighting the diagnostic complexities and imperative for prompt surgical management
