There can be side-effects from most medications and most surgical procedures. This surgery is no different. If anyone is considering the Nissen, they should sit down with their doc and have all the post-surgical side-effects discussed fully.
Why would someone want the surgery reversed? Are there adverse affects?
If a person has a hiatal hernia that is allowing the reflux of acid into the esophagus, a Nissen fundoplication can be done. It involves wrapping the top portion of the stomach around the esophagus to 'tighten' the lower esophagel sphincter.
There are other forms of endoscopic treatments, however. Most of them involve forms of 'plumping up' or 'tightening' the lower esophagel sphincter from within the esophagus.
In general, individuals might want to consider the endoscopic forms of treatment before they turn to the fundoplication surgery.
