Thoraco-abdominal duplications in children: Two case reports.

Abstract

IntroductionThoraco-abdominal duplication is rare congenital malformations of the notochord that occurs in only 2% of cases of alimentary tract duplications.We report two rare cases of thoraco-abdominal duplication, emphasizing the value of radiological assessment and discussing the place of diagnostic and therapeutic laparoscopy.Presentation of caseIt was a 12-year-old girl and an 8-month-old boy, admitted for epigastralgia and dysphagia with respiratory distress respectively. Imaging was in favor of pancreatic duplication with intra-thoracic extension for the first patient and gastro-esophageal duplication for the second. A mass excision was done laparoscopically for the first and by a thoracotomy for the second. The aftermath of the surgery was simple in both cases.Clinical discussionThoraco-abdominal duplications are rare congenital malformations that account for only 2% of cases of gastrointestinal duplications. Their diagnosis is difficult since the revealing symptomatology is not common. The treatment is only surgical is facilitated by the laparoscopy which has a diagnostic and therapeutic interest.ConclusionOur case reports focused on the difficulty of the diagnosis that is done by imaging and is confirmed by surgery with anatomopathological examination of the excised mass. Diagnostic and therapeutic minimally invasive approach should be used whenever possible.
