Erosive Esophagitis Overview

Erosive esophagitis is the most common complication of gastroesophageal reflux disease, caused by excessive acid reflux that damages the esophageal lining. This leads to inflammation, erosions, ulcerations, and in severe cases, bleeding. It is important to distinguish erosive esophagitis from nonerosive reflux disease, where no visible damage to the esophageal mucosa is observed.

Patients with erosive esophagitis often report symptoms such as heartburn and regurgitation, but more severe cases may include difficulty swallowing and painful swallowing. While most individuals respond well to treatment, a significant subset-up to 15 percent-continues to experience persistent symptoms despite receiving proton pump inhibitor therapy for eight weeks. These cases are considered treatment-resistant, highlighting the need for more effective and targeted therapeutic approaches.

Erosive Esophagitis Diagnosis and Treatment Algorithm

Esophagogastroduodenoscopy (EGD) is the primary diagnostic tool for confirming erosive esophagitis, especially in patients with refractory symptoms, alarm features, or those being evaluated for antireflux surgery. Unlike barium esophagram, which has limited utility, EGD allows direct visualization of mucosal damage, biopsy sampling, and therapeutic interventions for complications such as hemorrhage or strictures.

For patients with refractory disease or atypical symptoms, additional tests may be used to assess acid and non-acid reflux or esophageal motility. These include 24-hour impedance-pH monitoring, the 96-hour Bravo pH test, and high-resolution manometry. While not needed for most patients, these tests help evaluate persistent symptoms, detect weak acid or bile reflux, and guide treatment decisions, particularly before surgical intervention.

The main goals of treating erosive esophagitis are to relieve symptoms, heal the esophageal lining, prevent complications, and maintain long-term control of the disease. While lifestyle modifications can support treatment, most patients require acid-suppressive medications such as H2 blockers, proton pump inhibitors (PPIs), or P-CABs. PPIs are generally very effective, but some patients may continue to experience symptoms. In such cases, treatment can be optimized by adjusting the timing or dosage, switching to a different PPI, or adding a nighttime H2 blocker to improve symptom control.

For patients unresponsive to PPIs, P-CABs such as vonoprazan offer a newer treatment option with rapid and potent acid suppression, fewer rebound effects, and effective control of symptoms. Agents like motility drugs and sucralfate have limited roles and are reserved for specific cases, such as pregnancy or gastroparesis. Long-term maintenance therapy is often necessary, especially in severe cases, and is considered safe when properly monitored and tailored to individual patient needs.

"The idea that obesity may contribute to the development of erosive esophagitis is supported by biological mechanisms. Obesity is linked to higher intra-abdominal pressure, delayed gastric emptying, reduced lower esophageal sphincter (LES) tone, and more frequent transient LES relaxations-all of which can increase acid exposure in the esophagus."

"Several medications and health conditions can damage the esophageal lining and contribute to the development of erosive esophagitis. These include drugs like nitrates, calcium channel blockers, benzodiazepines, anticholinergics, and antidepressants. Additionally, medical conditions such as obesity, stroke, diabetes, and Parkinson's disease are known to impact esophageal function and are linked to an increased risk of erosive esophagitis."

"Patients with erosive esophagitis often require continued acid suppression with proton pump inhibitors or potassium-competitive acid blockers to prevent relapse and complications. These therapies should be used at the lowest effective dose and for the shortest duration. If treatment with proton pump inhibitors extends beyond six months, gradual tapering is advised before stopping. For mild or occasional symptoms, H2 receptor antagonists may be considered."
