Paraesophageal Hernia as a Cause of Chronic Asymptomatic Anemia in a 6 Years Old Boy; Case Report and Review of the Literature.

Esophageal hiatal hernia is defined as the prolapse of one or more intra-abdominal organs through the esophageal hiatus. Four types are identified: type Ι or sliding hiatal hernia, type II or paraesophageal hernia (PEH), type III or mixed hernia and type IV. Congenital type II esophageal hiatal hernia is caused by a remaining gap after the formation of pleuroperitoneal membrane. We present a case of a six years old boy admitted to our department, appearing with asymptomatic anemia, who was incidentally diagnosed with Type II esophageal hiatal hernia. After diagnostic investigation, the prolapsing stomach pouch was reduced, the hernia sac was excised, the crura of diaphragm were converged and a total fundoplication was performed, via open method. The patient had an uncomplicated postoperative period. We conclude that: 1) esophageal hiatal hernia should be included within diagnostic approach of a child with chronic non-hereditary anemia, 2) after a Type II esophageal hiatal hernia is diagnosed, a hernia repair surgery is indicated in short time, due to the severity of possible complications and 3) through the performance of total fundoplication, it is secured that the subdiaphragmatic abdominal part of esophagus will be retained, preventing the development of post-operative gastroesophageal reflux disease.
