Postoperative gastric outlet obstruction following hiatal hernia repair in an infant: A case report
Keywords:Hiatal hernia, Infantile hypertrophic pyloric stenosis, Postoperative emesis, Gastric outlet obstruction
Background: Infantile hypertrophic pyloric stenosis (IHPS) is an exceedingly rare cause of postoperative emesis in a case of hiatal hernia. Occasionally it may simulate other etiology of gastric outlet obstruction.
Case Presentation: A 32-day-old male baby presented with respiratory distress and vomiting since birth. Diagnosis of eventration of left hemi diaphragm was made on CT Chest. At surgery, hiatal hernia with an intrathoracic stomach was found, which was repaired. On 5th postoperative day, the baby developed vomiting after feeding which gradually turned to be projectile in nature over a week. Contrast meal performed showed malpositioned stomach with delayed emptying. At re-operation, a well-formed olive of pylorus was encountered; Ramstedt pyloromyotomy was done. Postoperative course remained uneventful.
Conclusion: IHPS is a rarely described association with hiatal hernia. Pyloric stenosis should be considered in differential diagnoses of postoperative emesis in infants with hiatal hernia.
