< b>GERD surgery (fundoplication): A surgical technique that strengthens
the barrier to acid reflux when the lower esophageal sphincter does not work normally
and there is gastro-esophageal reflux.
Fundoplication has been the standard surgical method for treating gastro-esophageal
reflux disease (GERD). GERD is the constellation of inflammation, pain (heartburn),
and complications that results when acid refluxes (regurgitates) from the stomach
back up into the esophagus. Under normal conditions, there is a barrier to acid
reflux. One part of this barrier is the lower-most muscle of the esophagus (called
the lower esophageal sphincter) which is contracted and closes off the esophagus
from the stomach most of the time. In people with GERD, the sphincter does not work
normally. It is weak or relaxes inappropriately, permitting the acid from the stomach
to go back up into the esophagus.
During fundoplication, the part of the stomach closest to the esophagus is gathered,
wrapped, and sutured around the lower end of the esophagus and the lower esophageal
sphincter. This increases the pressure at the lower end of the esophagus and thereby
reduces acid reflux. During fundoplication, other surgical steps frequently are
taken that also may reduce acid reflux. If there is a hiatal hernia, the hernial
sac may be pulled down from the chest and sutured so that it remains within the
abdomen. The opening in the diaphragm through which the esophagus passes from the
chest into the abdomen also may be tightened.
Fundoplication may be done using a large incision (in a laparotomy or thoracotomy)
or with a laparoscope that requires only several small punctures of the abdomen.
The advantage of the laparoscopic method is a speedier recovery and less post-operative
pain.
The term fundoplication is composed of fundo-, referring to the
fundus (the upper portion) of the stomach + -plication, an operation for
reducing the size of a hollow organ (in this case, the stomach) by taking folds
or tucks in its walls.
