Final answer:
Esophageal fundoplication is the surgical procedure for repairing an esophageal diaphragmatic hernia, which involves wrapping the top of the stomach around the lower esophagus. The correct option is 4.
Step-by-step explanation:
The procedure performed for an esophageal diaphragmatic hernia is termed esophageal fundoplication. An esophageal diaphragmatic hernia occurs when a part of the stomach pushes through the esophageal hiatus, an opening in the diaphragm where the esophagus passes through to connect to the stomach.
The esophageal hiatus is a structural opening which becomes the site of herniation in this condition. During the surgical procedure of esophageal fundoplication, the top part of the stomach (or fundus) is wrapped around the lower end of the esophagus and secured in place.
This helps reinforce the lower esophageal sphincter, preventing stomach acids and food from moving back up into the esophagus and reducing the herniation. The correct option is 4.
