Gastroesophageal Reflux Disease (GERD)*Antacid:
*Aluminum magnesium combinations (Mylanta,Maalox)
*Mucosal barrier fortifiers:*Sucralfate (Carafate)
*Laparoscopic Nissen fundoplication (LNF)
GERD*Therapeutic Procedures:
*Surgery (Fundoplication): laparoscopy
*In a fundoplication , the gastric fundus (upper part) of the stomach is wrapped, orplicated, around the lower end of the esophagus and stitched in place,reinforcing the closing function of the lower esophageal sphincter:
*Whenever the stomach contracts, it also closes off the esophagus instead of squeezing stomach acids into it.
*This prevents the reflux of gastric acid (in GERD).*The esophageal hiatus is also narrowed down by sutures to prevent or treat
concurrent hiatal hernia, in which the fundus slides up through theenlarged esophageal hiatus of the diaphragm.
*In a Nissen fundoplication, also called a complete fundoplication, the fundus iswrapped all the way 360 degrees around the esophagus. In contrast, surgeryfor achalasia is generally accompanied by either a Dor or Toupet partialfundoplication, which is less likely than a Nissen wrap to aggravatethedysphagia 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.
*The procedure is now routinely performed laparoscopically. When used to alleviategastroesophageal reflux symptoms in patients with delayed gastric emptying,it is frequently combined with modification of the pylorus via pyloromyotomy or pyloroplasty.
