Abstract
INTRODUCTION: Esophageal duplication is a rare form of digestive duplication. This congenital malformation may remain silent or manifest itself by respiratory signs such as compression. CASE PRESENTATION: We reported 1 case of esophageal duplication. This was a 12-year-old male child born at term, admitted to our level for chest pain and dysphagia evolving for 4 months. Upon further evaluation, fluid formation at the level of the right lower esophageal latero medial mediastinum was discovered and surgical intervention was necessary. The final diagnosis was an esophageal duplication cyst. DISCUSSION: Esophageal duplications are rare and represent 15 to 20 % of digestive duplications, often manifesting by respiratory and digestive signs, thus complicating the diagnosis. Imaging, including CT, esophageal transit or fibroscopy, consists of identifying the extent of the formation. Surgery is necessary in all cases before serious complications appear. CONCLUSION: The Cystic duplication of lower esophagus are rare and often pose a problem for positive diagnosis. Their treatment is surgical and must be undertaken before the onset of complications.
