Nissen fundoplication -> θολοπλαστική Nissen, επέμβαση πτύχωσης πυθμένα, ολική θολοπλαστική,, θολοπλαστική 360 μοιρών
Nissen fundoplication is a surgical procedure to treat gastroesophageal reflux disease (GERD) and hiatus hernia. In GERD it is usually performed when medical therapy has failed, but with paraesophageal hiatus hernia, it is the first-line procedure. The Nissen fundoplication is total (360°), but partial fundoplications known as Belsey fundoplication (270° anterior transthoracic), Dor fundoplication (anterior 180-200°) or Toupet fundoplication (posterior 270°) are also alternative procedures with somewhat different indications.
In a Nissen fundoplication, also called a complete fundoplication
, the fundus is wrapped all the way 360 degrees around the esophagus. In contrast, surgery for achalasia is generally accompanied by either a Dor or Toupet partial fundoplication, which is less likely than a Nissen wrap to aggravate the dysphagia that characterizes achalasia. In a Dor (anterior) fundoplication, the fundus is laid over the top of the esophagus; while in a Toupet (posterior) fundoplication, the fundus is wrapped around the back of the esophagus.http://en.wikipedia.org/wiki/Nissen_fundoplication
