BACKGROUND

back to top

Description

Gastroesophageal reflux disease (GERD) is a chronic, progressive disorder involving the backward flow of gastroduodenal contents into the esophagus. GERD is the most common serious condition of the gastrointestinal (GI) tract. It is caused by (1) a defective lower esophageal sphincter, (2) a gastric emptying disorder, or (3) failed esophageal peristalsis.

Incidence

  • 10% general population
  • 15-20% developmentally disabled

Prevalence

  • 65% of adults have experienced heartburn
  • 44% experience monthly heartburn

Influencing Factors

  • Malfunction of lower esophageal sphincter (LES)
  • Spasticity
  • Kyphoscoliosis
  • Medications that lower LES pressure
  • Alcohol, tobacco, or caffeine intake
  • Intake of spicy food, excess fat or chocolate
  • Tube feeding
  • Overeating or eating too fast
  • Enteral nutrition or nasogastric tube
  • Delayed gastric emptying
  • Acid hypersecretion
  • Postural drainage
  • Immobility
  • Constipation
  • Supine positioning
  • Chest trauma
  • Pregnancy

Signs and Symptoms

  • Heartburn (70-85%)
  • Chest pain (33%)
  • Regurgitation (60%)
  • Dysphagia
  • Recurrent vomiting
  • Rumination
  • Upper GI bleeding
  • Hematemesis
  • Hypochromic microcytic anemia
  • Painful or difficult swallowing (15-20%)
  • Globus (“lump in the throat” sensation)
  • Pharyngitis
  • Recurrent laryngitis (not infectious)
  • Bronchospasm (15-20%)
  • Hoarseness
  • Coughing
  • Difficulty breathing
  • Blood in the stool
  • Poor weight gain

Possible Complications

  • Esophagitis
  • Stricture of esophagus (10-15%)
  • Barrett’s esophagus (10%)
  • Esophageal dysplasia
  • Aspiration pneumonia
  • Respiratory problems (5-10%)
  • Failure to grow and thrive in infancy
  • Cyanotic episodes
  • Hiatal hernia
  • Anemia
  • Ear, nose, throat complications (5-10%)
  • Hemorrhage (3%)
  • Behavioral disturbances
  • Death

MEDICAL MANAGEMENT CONSIDERATIONS

back to top

Note: These considerations are in addition to the normal medical care provided to an individual without GERD. All recommendations can be addressed through clinical examination by the primary care provider, unless otherwise noted.

Many treatments relieve symptoms of heartburn but fail to stop reflux. Because the patient does not experience pain, it is possible for the epithileal lining of the esophagus to be slowly destroyed without the physician’s knowledge, which may lead to overt cancer of the esophagus. Thus, it is very important to address symptoms of regurgitation in addition to symptoms of heartburn.

Esophagitis heals in up to 90% of cases treated with intensive medical therapy. However, these treatments do not address the underlying mechanical cause of GERD; thus, symptoms recur in more than 80% of cases within one year of medication withdrawal. In these cases, surgical therapy may be beneficial.

Diagnosis

Perform the following test(s) until diagnosis can be made. The choice of which specific test(s) to perform may depend upon the availability of the test, the qualifications and willingness of the examiner, and the ability of the patient to cooperate with the procedure.

  • Upper GI X-ray series (Barium swallow)
  • Endoscopy with esophageal biopsy
  • Intraesophageal pH monitoring (24 hours)- (Gold Standard)
  • Technetium 99TcM scan
  • Esophageal manometry
  • Serum studies

Treatment Phase I: Lifestyle and Diet Modifications

  • Discourage intake of fatty foods, onions, caffeine, alcohol, tobacco, chocolate, peppermint, spearmint, carbonated beverages and citrus
  • Recommend small, thickened feedings
  • Avoid rigorous activity or prolonged lying down after eating
  • Remain upright or lie on side after eating
  • Elevate head of bed at least 6 inches
  • Counsel to lose weight if obese
  • Recommend loose-fitting clothing
  • Avoid bending at the waist
  • Avoid medications that affect lower esophageal sphincter (theophylline, thioridazine, baclofen, albutrol, etc.)
  • Recommend over-the-counter antacids

Treatment Phase II: Long-term Drug Therapy

Note: Consider only if lifestyle and diet modifications do not generate marked improvement.

  1. Histamine-2 receptor blocking agents (ranitidine, cimetidine, famotidine, nazatidine) to reduce the production of stomach acid
  2. Prokinetic agents (metoclopramide, etc.) to strengthen the lower esophageal sphincter and induce the stomach to empty faster, there are some rare, but serious, cardiac side effects for the most commonly prescribed prokinetic agent

Treatment Phase III: Aggressive Drug Therapy (70-90% effective)

Note: Consider only when no significant response to lifestyle changes or long-term drug therapy.

  1. Higher dose of H-2 receptor blocking agents
  2. Proton pump inhibitors (lansoprazole or omeprazole) to eliminate the production of stomach acid

Treatment Phase IV: Surgery (80-93% effective)

Surgery has been found to be more effective than medical therapy in improving symptoms and endoscopic signs of esophagitis. However, it should only be considered for individuals who:

  • Have failed medical management;
  • Opt for surgery due to age, time, or medication expense;
  • Have complications such as Barrett’s esophagus, stricture, ulcers;
  • Have excessive symptoms such as asthma, hoarseness, cough, chest pain, aspiration;
  • Do not have a limited life expectancy; or
  • Do not have co-morbid conditions that would prohibit safe surgical intervention.

The primary goals of surgical intervention for GERD are to:

  • Reestablish the antireflux barrier without undue side effects;
  • Position the lower esophageal sphincter within the abdomen where it is under positive pressure; and
  • Close any associated hiatal defect.

Below is a list of possible surgical procedures, although there is no clear consensus in regard to which types are superior to others for persons with developmental disabilities.

  • Nissen total fundoplication (for patients with normal esophageal motility)
  • Belsey, Toupet, or D’or partial fundoplication (for patients with compromised esophageal motility)
  • Pyloroplasty for those who receive fundoplication and have delayed gastric emptying
  • Collis gastroplasty for esophageal lengthening (70% success)
  • Hill arcuate ligament repair
  • Small-bore weighted feeding tube from nose to duodenum
  • Esophagectomy (consider only if dysphagia stricture and profound loss of esophageal motility)

Note: It has recently been suggested that there may exist a relationship between Helicobacter pylori infection and gastrointestinal disorders. Although this relationship has not been fully established, it may be possible that eradication of H. pylori can exacerbate gastroesophageal reflux in the general population and possibly in patients with developmental disabilities.
