Heartburn is a burning feeling in the chest caused by stomach acid travelling up towards the throat (acid reflux). GERD is a chronic condition. Once it begins, it usually is life-long. If there is injury to the lining of the esophagus (esophagitis), this also is a chronic condition. Moreover, after the esophagus has healed with treatment and treatment is stopped, the injury will return in most patients within a few months. Once treatment for GERD is begun it will need to be continued indefinitely although. However, some patients with intermittent symptoms and no esophagitis can be treated only during symptomatic periods.
The surgical procedure that is done to prevent reflux is technically known as fundoplication and is called reflux surgery or anti-reflux surgery During fundoplication, any hiatal hernial sac is pulled below the diaphragm and stitched there. In addition, the opening in the diaphragm through which the esophagus passes is tightened around the esophagus. Finally, the upper part of the stomach next to the opening of the esophagus you could try these out into the stomach is wrapped around the lower esophagus to make an artificial lower esophageal sphincter. All of this surgery can be done through an incision in the abdomen (laparotomy) or using a technique called laparoscopy During laparoscopy, a small viewing device and surgical instruments are passed through several small puncture sites in the abdomen. This procedure avoids the need for a major abdominal incision.
The acid perfusion (Bernstein) test is used to determine if chest pain is caused by acid reflux. For the acid perfusion test, a thin tube is passed through one nostril, down the back of the throat, and into the middle of the esophagus. A dilute, acid solution and a physiologic salt solution (similar to the fluid that bathes the body’s cells) are alternately poured (perfused) through the catheter and into the esophagus. The patient is unaware of which solution is being infused. If the perfusion with acid provokes the patient’s usual pain and perfusion of the salt solution produces no pain, it is likely that the patient’s pain is caused by acid reflux.
Several different abnormalities of the LES have been found in patients with GERD. Two of them involve the function of the LES. The first is abnormally weak contraction of the LES, which reduces its ability to prevent reflux. The second is abnormal relaxations of the LES, called transient LES relaxations. They are abnormal in that they do not accompany swallows and they last for a long time, up to several minutes. These prolonged relaxations allow reflux to occur more easily. The transient LES relaxations occur in patients with GERD most commonly after meals when the stomach is distended with food. Transient LES relaxations also occur in individuals without GERD, but they are infrequent.
