What is the definition or description of: hiatal hernia surgery?

Surgery: A proper diagnosis is required to expect the best results for hiatal hernia surgery. It is a hernia weakness in the diaphragm muscle and the stomach pushes through. Usually a laparoscopic procedure using a portion of the patient's upper stomach to wrap around the lower esophagus. This repairs he hernia defect & tightens the lower esophagus so food will not reflux into the esophagus.

Diaphragm repair: Hiatal hernia is a stretched out opening in the diaphragm through which the esophagus passes. Since the chest acts like a vacuum (how we breathe), the larger hole allows the stomach, and sometimes other organs to be "sucked" up into the chest. Surgery to repair this is usually done laparoscopically, and involves closing the hole to the right size with sutures. Mesh use is controversial.
