Nissen fundoplication
Nissen Fundoplication
Nissen fundoplication (pronounced: nis-en fun-doh-pli-kay-shun) is a surgical procedure used to treat gastroesophageal reflux disease (GERD) and hiatal hernia.
Etymology
The procedure is named after Dr. Rudolph Nissen, a Swiss surgeon who first performed the procedure in 1955.
Definition
In a Nissen fundoplication, the gastroesophageal junction (where the esophagus and stomach meet) is wrapped by the upper part of the stomach (the fundus) to reinforce the closing function of the lower esophageal sphincter.
Procedure
During the procedure, the surgeon wraps the top of the stomach around the lower esophagus. This strengthens the valve between the esophagus and stomach, which stops acid from backing up into the esophagus as easily. This provides relief from the symptoms of GERD.
