A NIssen fundoplication is the definitive surgical treatment for GERD where medical therapy has failed and to acheive a permanent solution to the problem of acid reflux backup into the stomach.
During the Nissen fundoplication, the upper part of the stomach is wrapped around the LES to strengthen the sphincter, prevent acid reflux, and repair a hiatal hernia.
The Nissen fundoplication is usually performed as a laparoscopic (minimally invasive) procedure.The doctor uses small instruments that hold a camera to look at the abdomen and pelvis. When performed by experienced surgeons, laparoscopic fundoplication is safe and effective in people of all ages, including infants.
The procedure is reported to have the same results as the standard fundoplication, and people can leave the hospital in 1 to 3 days and return to work in 2 to 3 weeks.
