Los Angeles classification

The Los Angeles classification aims to separate the lesions from erosive esophagitis according to the severity, so that the most suitable treatment for the lesion can be decided.

Grade of seriousness of the injury



1 or more erosions smaller than 5 mm.


1 or more erosions greater than 5 mm, but they are not joined together.


Erosions that unite, the ones that involve less than 75% of the organ.


Erosions that are found in at least 75% of the circumference of the esophagus.

When the lesions of erosive esophagitis are found to be recurrent, there is a greater risk of cancer arising in the esophagus, so it may be necessary that surgical treatment be indicated first, before the use of medicines.

Erosive esophagitis in most cases is a consequence of untreated esophagitis, so that the lesions continue to appear and produce symptoms.

In addition, other situations that favor the development of the esophagitis and the gastroesophageal reflux are due to the fact that the content of the stomach acid reaches the esophagus and promotes irritation in the mucosa, favoring the emergence of lesions.

Erosive esophagitis can also occur more frequently in people who smoke as a result of the consumption of processed and fatty foods.

The treatment for erosive esophagitis depends on the factor that caused it; however, it is normally carried out through the follow-up of a nutritionist, who may indicate to suspend the use of cigarettes, in case the individual is a smoker; reduce the consumption of industrialized and fatty foods, and lose weight in people with the onset of obesity.

Likewise, it may be necessary to use certain medications, such as the following:

  • Proton pump inhibitors (PPIs), like omeprazole, esomeprazole and lansoprazole, they inhibit the production of gastric yoke by the stomach, which prevents it from reaching the esophagus;
  • H₂ receptor inhibitors of histamine, such as famotidine, cimetidine and nizatidine, used when PPIs have the expected effect, helping to reduce the amount of acid in the stomach;
  • prokinetics, such as domperidone and metoclopramide, used to accelerate stomach emptying.

In case the person is under treatment with anticholinergics, such as Artane or Akineton, or calcium channel blockers, such as amlodipine or verapamil, the gastroenterologist can give specific recommendations on how to use the prescribed drugs.

Surgery for erosive esophagitis alone is indicated in case the lesions do not improve or when the symptoms are persistent and all the treatment options before exposed and were used. This surgery consists of rebuilding a small valve that separates the union between the esophagus and the stomach, thus preventing the gastric yoke from returning through this route and causing new injuries.
