Gastroesophageal Reflux Disease: From Diagnosis to Treatment

image_pdfFavoriteLoadingFavorite

SUMMARY:

Gastroesophageal reflux disease (GERD) is a chronic condition characterized by the recurrent regurgitation of acidic stomach contents into the esophagus, and/or more proximally, due to a decrease in tone or inappropriate relaxation of the lower esophageal sphincter. GERD has been estimated to occur in 20% of the population of high-income countries. This condition may be diagnosed in association with classical symptoms or following recognition of GERD-related complications.

Symptoms

Esophageal Symptoms

Symptoms of GERD may be limited to the esophagus and GI tract (typical GERD) and/or may be extra-esophageal

  • Heartburn/chest pain
  • Acid regurgitation
  • Nausea
  • Dysphagia
  • Belching
  • Bloating
  • Bleeding

Extra-esophageal Symptoms

Will occur with or rarely without typical GERD symptoms | Silent GERD is an unlikely diagnosis

  • Extra-esophageal symptoms may include those of laryngopharyngeal reflux (LPR)
    • Hoarseness/chronic laryngitis
    • Chronic cough, including cough that awakens from sleep/wheezing
    • Recurrent throat irritation and/or throat clearing
    • Excessive pharyngeal mucus
    • Globus (sensation of a lump in the throat)
    • Chronic sinusitis
    • Eustachian tube dysfunction and otitis
    • Change in tone or pitch of speech
  • Additional extra-esophageal symptoms may include
    • Halitosis
    • Dental caries
    • Erosion of dental enamel

Complications

  • Esophageal ulcers or strictures
  • Barrett’s esophagitis
  • Esophageal carcinoma- adenocarcinoma may follow Barrett’s with dysplasia, lower esophageal location
  • Aspiration

Risk Factors

  • Obesity
  • Female
  • Pregnancy
    • Estrogen | Progesterone | Upward pressure of gravid uterus upon stomach
  • Smoking
  • Specific foods
    • Chocolate | Peppermint | Caffeine | Alcohol | Tomato | Citrus | Fatty foods
  • Eating habits
    • Eating rapidly | Large portions, before sleep
  • Hiatal hernia
  • Medication
    • Antibiotics (tetracycline, clindamycin) | Bisphosphonates (fosamax, boniva, actonel, atelvia) | Anticholinergics (e.g., ditropan) | Iron supplements | Potassium supplements | Opioids | NSAIDs | Tricyclics | Calcium channel blockers | ACE inhibitors | Progesterone | Diazepam (Valium) | Temazepam (Restoril) | Quinidine

Note: Population studies suggest that there is an inverse relationship between H. pylori and GERD | Hypothesis is that H. pylori may associated with decreased acid production and eradication of the pathogen may exacerbate GERD due to increased risk of esophagitis

Differential Diagnosis

  • Coronary Disease
    • Careful evaluation required | GERD may be exacerbated by physical activity (e.g., abdominal crunches or presses, high impact exercise, bending, lifting, running)
  • Peptic ulcer disease
    • Nausea | Vomiting | Epigastric pain
  • GI malignancy
    • Dysphagia | Vomiting | Weight loss
  • Biliary disease
    • Abdominal pain | Jaundice
  • Upper GI motility disorder
    • Dysphagia | Vomiting of undigested food
  • Eosinophilic esophagitis
    • Dysphagia | Food impaction | Chest pain

Treatment

Lifestyle Modification

  • Weight reduction
  • Smoking cessation
  • Alcohol avoidance
  • Avoid food and beverage triggers and eating prior to bedtime
    • Aim for small portions, slower eating, thorough chewing
  • Head elevation with wedge or 6 inch blocks, not with multiple bed pillows, as this places pressure on the abdomen and may worsen reflux

Medication: Proton Pump Inhibitors (PPIs)

  • Lansoprazole (Prevacid) | Pantoprazole (Protonix) | Esomeprazole (Nexium) | Omeprazole (Prilosec)  | Rabeprazole (Aciphex)
  • If incomplete response to once daily dosing
    • Consider twice daily dosing, change in timing or change in dose
    • Some may benefit from intermittent PPI treatment, as needed
  • Treatment recommended for 4 to 8 weeks
    • 4 weeks if uncomplicated | 8 weeks for confirmed erosive esophagitis
    • Follow by taper or cessation of medication, then use of PPI as needed
  • In general, avoid long-term treatment with PPIs
    • Potential for acute kidney injury or chronic kidney disease, C. difficile infection, osteoporosis, risk for gastric cancer
  • In general, avoid long-term treatment with PPIs
    • Acid rebound may occur following acute cessation of long-term PPI treatment so consider taper
    • If long-term treatment is required, use lowest effective dose
    • Patients with Barrett’s esophagus or esophagitis need continuous daily PPI at lowest beneficial dose, as well as serial endoscopy
    • Check hepatic dosing
  • Other medications
    • H2 receptor antagonists such as famotidine (Pepcid) are less effective than PPI’s
    • OTC antacids have limited efficacy, though may be used if symptomatic benefit

Note: Monitor patient response | If symptoms persist or there is weight loss after initial treatment refer to GI for further evaluation | Further evaluation may include manometric testing or endoscopy | Weight loss, dysphagia or bleeding may suggest malignancy

Evaluation and Treatment of Extra-esophageal GERD

  • Investigate for non-GERD related etiologies
  • American Gastroenterological Association recommends against acid suppression therapy for acute treatment in the absence of concurrent typical GERD symptoms
  • pH monitoring is recommended, particularly in patients without typical GERD
  • If no response to PPI, consider further diagnostics: ENT, pulmonary and/or allergy
    • Laryngoscopy-findings of erythema and edema, though non-specific to LPR and may be seen in over 80% of healthy controls and unreliable inter-observer validity to findings
    • multichannel intraluminal impedance and pH monitoring more accurate than routine ambulatory pH monitoring

Anti-reflux Surgery 

  • When PPI and surgery offer similar efficacy, recommend PPI for safety
  • Consider surgery if patient responds to PPI treatment but is intolerant or does not wish to continue PPI long term
  • Consider surgery if no response to PPI
  • Surgical procedures include
    • Laparoscopic fundoplication: Following endoscopy to rule out malignancy and manometry to rule out motility disorders (achalasia) | If GERD recurs after surgery –recommend endoscopy and pH monitoring
    • Stretta procedure: Radiofrequency ablation above and below the LES to thicken the LES
    • Trans-oral incisionless fundoplication: Involves circumferentially suturing the gastroesophageal area with non-absorbable material, applied via endoscopy | Long-term efficacy uncertain
    • LINX procedure (magnetic sphincter augmentation): Involves endoscopically placing titanium beads with magnetized centers around the lower esophagus to increase tone | Limited long-term safety data, though response, in terms of post-op PPI requirements and GERD-related symptoms, appears similar to laparoscopic fundoplication
