What is the goal of a Nissen fundoplication procedure?

The goal of a Nissen fundoplication procedure is to correct a hiatal hernia, particularly when it is associated with gastroesophageal reflux disease (GERD). This surgical procedure involves wrapping the top part of the stomach (the fundus) around the lower esophagus to strengthen the lower esophageal sphincter. This reinforcement prevents acid reflux and helps alleviate symptoms related to GERD, which can often be exacerbated by the presence of a hiatal hernia.

While the procedure can have secondary benefits, such as reducing symptoms related to esophageal inflammation due to acid exposure, its primary aim is to address the structural issue of the hiatal hernia itself. In contrast, the other options presented refer to different procedures or conditions that are not directly related to the purpose of a Nissen fundoplication.
