Study Notes

GERD Overview

GERD (Gastroesophageal Reflux Disease) is characterized by the recurrent backflow of gastric contents into the esophagus, leading to symptoms and potential tissue damage.
Typical GERD symptoms include acid regurgitation and heartburn.
Upper endoscopy is not essential for initial diagnosis; empiric acid suppressive therapy can commence in patients without alarm features.

Symptoms and Management

Heartburn is a burning sensation located behind the breastbone.
Regurgitation involves the experience of gastric contents flowing into the mouth or hypopharynx.
Higher incidence of heartburn and hoarseness observed in men with erosive esophagitis.

Diagnosis Criteria

NERD (Non-Erosive Reflux Disease) is diagnosed when there are no esophageal mucosal lesions noted during upper endoscopy despite typical symptoms.
Upper endoscopy is necessary for confirming NERD.
Common GERD questionnaires in the Philippines include the Frequency Scale for the Severity of GERD (FSSG) and the Gastoesophageal Reflux Disease Questionnaire (GerdQ).

Treatment Protocols

Standard dose PPIs (Proton Pump Inhibitors) are foundational treatment for erosive esophagitis, recommended once daily for eight weeks prior to breakfast.
Obesity significantly raises the risks of GERD symptoms, erosive esophagitis, and esophageal adenocarcinoma.
Head elevation during sleep and using left lateral decubitus position can improve esophageal pH levels.

Therapy Adjustments

If there is only partial symptom relief after eight weeks of standard PPI treatment, the same PPI should be given twice daily or switched to a different PPI.
Upon symptom relapse after initial GERD treatment, NERD patients may use on-demand PPI therapy, while continuous PPI therapy is suggested for those with moderate to severe erosive esophagitis.

Additional Treatments

Alginate-antacid combinations are recommended for relief of episodic and postprandial reflux symptoms.
Refractory GERD is characterized by inadequate symptom improvement despite diligent PPI adherence for at least eight weeks.
Ambulatory reflux studies are suggested for patients with refractory GERD displaying normal upper endoscopy results.

Monitoring and Alternative Medications

Ambulatory reflux monitoring is the sole test for assessing abnormal esophageal acid exposure and symptom association.
H2-receptor blockers, pain modulators, and TLESR (Transient Lower Esophageal Sphincter Relaxations) reducers may serve as adjunctive treatments for refractory GERD.
Baclofen is effective in reducing TLESRs, decreasing upright reflux and regurgitation, and improving overall symptom scores.
Citalopram, a selective serotonin reuptake inhibitor, benefits patients with a hypersensitive esophagus that are unresponsive to PPI therapy.

Extraesophageal Manifestations

Chronic cough, laryngitis, and asthma may indicate extraesophageal manifestations of GERD.
For patients with extraesophageal GERD without alarm features, standard-dose PPI treatment (twice daily) for at least 12 weeks is recommended.

Barrett’s Esophagus (BE)

Barrett's esophagus is the replacement of squamous epithelium in the distal esophagus with abnormal columnar epithelium above the gastroesophageal junction, associated with specialized intestinal metaplasia.
Barrett's esophagus is a risk factor for distal esophageal adenocarcinoma.
The Prague Criteria is used during endoscopy to assess the extent of Barrett’s esophagus across different populations.

Long-term considerations

PPI treatment can regress Barrett’s esophagus and lower the risk of high-grade dysplasia and adenocarcinoma.
Chronic GERD may contribute to the development of Barrett's metaplastic epithelium, progressing to dysplasia and adenocarcinoma.
Long-term PPI use can lead to complications like vitamin B12 deficiency, iron deficiency, and increased risk of infections and fractures.

Pregnancy Management

Short-term PPI treatment is limited to the last two trimesters for pregnant women with GERD.
H2RAs and antacids (excluding sodium bicarbonate) are well-studied for safety and efficacy in pregnancy.

Diagnostic Approaches

Routine screening and treatment of Helicobacter pylori infection in GERD management is not standard.
Upper endoscopy is unnecessary for diagnosing GERD.
Endoscopy is recommended when alarm features are present or in cases of new onset alarm symptoms, post-treatment complications, or after inadequate symptom response to therapy.

Surgical Options

Surgery, particularly laparoscopic fundoplication, may be considered for patients whose symptoms improve with PPI therapy but who are unsuitable for long-term medical management.
Pre-surgical evaluation with esophageal manometry and ambulatory reflux studies is essential to rule out other disorders.
