Study Notes
Gastroesophageal Reflux Disease (GERD)
- GERD refers to the reverse flow of stomach contents, including hydrochloric acid, into the esophagus.
- Common symptoms include heartburn (burning retrosternal pain after meals) and dyspepsia (epigastric burning pain).
- Chronic acid exposure leads to esophagitis, strictures, aspiration, GI bleeding, and increased cancer risk.
Complications of GERD
- Esophagitis: Inflammation and ulcers in the esophagus leading to dysphagia (pain with swallowing).
- Stricture formation: Chronic inflammation causes narrowing of the esophagus.
- Aspiration: Acid can enter the airway, leading to laryngitis (hoarseness) and bronchial inflammation, exacerbating conditions like asthma.
- GI bleeding: Erosion of blood vessels may cause anemia and fatigue.
- Esophageal cancer: Long-term damage increases risk, evolving from normal squamous cells to columnar via metaplasia, ultimately leading to dysplasia and potential adenocarcinoma.
Pathophysiology
- Metaplasia: Changes from stratified squamous to columnar cells due to chronic acid exposure, marked by dysplasia leading to neoplastic changes.
- Common mechanisms leading to GERD include low lower esophageal sphincter (LES) tone, increased intra-abdominal pressure, hiatal hernias, and increased acid production.
Causes of GERD
- Low LES tone can be caused by smoking, alcohol, caffeine.
- Hiatal hernia: Most commonly sliding hernias, where the upper part of the stomach moves above the diaphragm.
- Increased acid production due to NSAIDs, alcohol, smoking, and Zollinger-Ellison syndrome.
- Elevated intra-abdominal pressure from pregnancy, obesity, large meals, or gastroparesis.
Diagnostic Approach
- Initial assessment should include an ECG to rule out acute coronary syndrome if there are atypical retrosternal chest pains.
- Empiric proton pump inhibitor (PPI) trial is initiated if ECG is normal; improvement supports GERD diagnosis.
- Alarm symptoms necessitate further investigation via endoscopy (EGD) to check for esophagitis, strictures, or cancer.
- Esophageal manometry and pH monitoring help assess motility and confirm acid reflux; a DeMeester score >14.7 suggests GERD.
Treatment Strategies
- Lifestyle modifications: Avoid smoking, caffeine, and alcohol.
- Manage intra-abdominal pressure by losing weight, avoiding large meals, and considering prokinetic agents like metoclopramide for gastroparesis.
- Use H2 receptor antagonists for mild cases; PPIs for more severe esophagitis or frequent symptoms (more than twice a week).
- Surgical options like Nissan fundoplication may be considered for refractory cases or when structural interventions are needed due to severe complications.
- Continuous monitoring for potential cancer in patients with Barrett's esophagus, recommending an EGD every 3-5 years, with biopsies to assess dysplasia.
Summary
- GERD is a chronic condition with various complications stemming from acid reflux, requiring a comprehensive diagnosis and a multi-faceted treatment approach.
- Understanding its pathophysiology, causes, and treatment options is crucial for effective management and reducing future risks.
Gastroesophageal Reflux Disease (GERD)
- GERD involves the backward flow of stomach contents, primarily hydrochloric acid, into the esophagus.
- Symptoms include heartburn (burning sensation behind the sternum post-meals) and dyspepsia (epigastric pain).
- Chronic exposure to acid can result in esophagitis, strictures, aspiration, gastrointestinal bleeding, and heightened cancer risk.
Complications of GERD
- Esophagitis can cause inflammation, ulcers, and dysphagia (difficulty swallowing).
- Strictures develop from ongoing inflammation, leading to narrowing of the esophagus.
- Aspiration may occur when acidic contents enter the airway, resulting in laryngitis and exacerbating asthma.
- Gastrointestinal bleeding due to erosions can result in anemia and fatigue.
- Long-term damage raises the risk of esophageal cancer, evolving through changes from squamous cells to columnar cells, potentially resulting in dysplasia and adenocarcinoma.
Pathophysiology
- Metaplasia signifies the transition from stratified squamous to columnar cells due to persistent acid exposure, often resulting in dysplasia and subsequent neoplastic changes.
- Key mechanisms causing GERD include low lower esophageal sphincter (LES) tone, increased intra-abdominal pressure, hiatal hernias, and heightened acid production.
Causes of GERD
- Low LES tone can be influenced by smoking, alcohol intake, and caffeine consumption.
- Hiatal hernias, primarily sliding hernias, occur when part of the stomach protrudes above the diaphragm.
- Increased acid production may arise from NSAID use, consumption of alcohol and tobacco, or Zollinger-Ellison syndrome.
- Elevated intra-abdominal pressure is associated with pregnancy, obesity, large meals, or conditions like gastroparesis.
Diagnostic Approach
- Initial evaluations should include an ECG to exclude acute coronary syndrome if atypical chest pain is experienced.
- An empiric trial of proton pump inhibitors (PPIs) may confirm GERD if symptoms improve after an ECG shows normal results.
- Alarm symptoms warrant further investigation via endoscopy (EGD) to identify esophagitis, strictures, or malignancies.
- Esophageal manometry and pH monitoring assess motility and confirm acid reflux; a DeMeester score over 14.7 suggests GERD diagnosis.
Treatment Strategies
- Lifestyle modifications are critical; quitting smoking and reducing caffeine and alcohol intake are recommended.
- Managing intra-abdominal pressure includes weight loss and meal size moderation; prokinetic agents like metoclopramide may assist in gastroparesis.
- H2 receptor antagonists are suitable for mild GERD cases, while PPIs are effective for moderate to severe symptoms occurring more than twice weekly.
- Surgical consideration exists for refractory cases or severe structural complications, such as Nissan fundoplication.
- Patients with Barrett's esophagus should undergo continuous monitoring through frequent EGD procedures every 3-5 years, including biopsies to evaluate for dysplasia.
Summary
- GERD is a chronic disorder necessitating thorough diagnosis and a comprehensive treatment strategy, emphasizing pathophysiology, causative factors, and management techniques to mitigate complications and enhance patient outcomes.
