PY - 2014 T2 - Operative Pediatric Surgery, 2e AB - Gastrointestinal duplications may occur anywhere from the mouth to the anus.Symptoms may be related to compression of normal structures, such as respiratory distress from compression of the airway or compression of the bowel by a cystic duplication causing obstruction. Symptoms may be related to mass effect with pain or obstruction of the pancreatic duct or common bile duct with either pancreatitis or jaundice.Symptoms may be caused by a mass lesion with subsequent torsion of the intestine.Ectopic gastric mucosa may cause symptoms by acid production in areas where the mucosa is not structured to handle the acid load; this results in bleeding or perforation.Symptoms may be related to a connection from a thoracoabdominal duplication to the spine with meningitis.Duplications may be tubular or cystic.Infection may cause a duplication to rapidly enlarge. This is most significant if the lesion is near the airway.Treatment of duplications is complete resection if possible. In cases where complete resection is not possible the principles of treatment include drainage of the lesion into the gastrointestinal tract and removal or destruction of any ectopic gastric muscoa.If the duplication has a spinal connection, this must be dealt with at the time of resection.
