Common Tenets in Repair of Primary Paraesophageal Hernias: Reducing Tension and Maximizing Length

Tension-free repair remains the most important principle of surgical management of giant paraesophageal hernias. The axial tension is relieved by generous circumferential mobilization of the esophagus in the mediastinum to the level of subcarina. An esophageal lengthening procedure may be necessary for a true short esophagus. The radial tension is managed by mobilizing the left and right diaphragmatic crus. Adjunctive procedures such as pleurotomy or diaphragmatic relaxation incisions may be needed to further reduce the tension on the repair.
