Hiatal hernia repair is a surgical intervention aimed at correcting the anatomical disruption caused by a hiatal hernia. This condition occurs when a portion of the stomach protrudes into the chest cavity through the diaphragm. The surgery typically involves repositioning the stomach to its normal location and repairing the opening in the diaphragm. By addressing these structural issues, hiatal hernia repair aims to alleviate symptoms such as heartburn, regurgitation, chest pain, and difficulty swallowing.
