In recent years esophageal hiatal hernia has been established as a symptom-producing entity worthy of differential diagnosis in coronary artery disease, cholecystitis, peptic ulcer, carcinoma, and anemia. Despite the wealth of literature on hiatal hernia, its association with anemia, although well recognized, is only sporadically discussed. It is with this aspect of esophageal hiatal hernia that this report deals.
Neglecting the harassing aspects of embryology, anatomy, and physiology, a most useful, simple, and descriptive classification of esophageal hiatal hernia is that suggested by Mobley and Christensen.1
Esophageal hiatal hernia without shortening of the esophagus
With upward displacement of the esophagogastric junction (sliding type)
Without displacement of the esophagogastric junction (paraesophageal type)
Esophageal hiatal hernia with shortening of the esophagus
