What are the treatment options for a patient with a hiatal hernia?

Treatment Options for Hiatal Hernia

The management of hiatal hernia should follow a stepwise approach beginning with lifestyle modifications and medical therapy, progressing to surgical intervention only for patients with refractory symptoms or complications. 1

Initial Management: Lifestyle and Medical Therapy

Lifestyle Modifications

• Avoid meals within 3 hours of bedtime
• Elevate head of bed 6-8 inches
• Weight management for overweight/obese patients
• Identify and avoid personal trigger foods
• Diaphragmatic breathing exercises may help manage symptoms 1

Medical Management

1. First-line therapy: Proton Pump Inhibitors (PPIs)

   • Single-dose PPI for 4-8 weeks, taken 30-60 minutes before meals
   • If inadequate response, increase to twice-daily dosing or switch to more potent PPI 1
   • For patients with large hiatal hernias, PPIs are particularly important for controlling reflux symptoms 2

2. Adjunctive medications:

   • Alginate-based antacids for breakthrough symptoms (particularly effective for hiatal hernia patients) 1
   • H2-receptor antagonists for nighttime symptoms (note: limited by tachyphylaxis) 1
   • Baclofen for regurgitation or belch-predominant symptoms 3, 1
   • Prokinetics if concurrent gastroparesis is present 1

Surgical Management

Indications for Surgery

• Refractory symptoms despite optimal medical therapy
• Large hiatal hernias with obstructive symptoms (dysphagia, vomiting)
• Complications such as incarceration or risk of strangulation
• Objectively documented gastroesophageal reflux 3

Surgical Options

1. Laparoscopic fundoplication with hiatal hernia repair

   • Standard approach with type of fundoplication tailored to patient's esophageal motility 1
   • Significantly improves health-related quality of life at 3 months and 1 year compared to medical therapy 3
   • Key operative steps include:
     • Reduction and excision of hernia sac
     • Ensuring 3 cm of intraabdominal esophageal length
     • Crural closure with mesh reinforcement
     • Anti-reflux procedure 4

2. Alternative procedures:

   • Magnetic sphincter augmentation combined with crural repair
   • Transoral incisionless fundoplication (for carefully selected patients with small hiatal hernias)
   • Roux-en-Y gastric bypass (for obese patients with proven GERD) 1

Special Considerations

Small vs. Large Hiatal Hernias

• Small hernias often cause reflux symptoms and respond well to medical therapy 2
• Large hernias more commonly cause obstructive symptoms (dysphagia, vomiting) and may require surgical intervention 2, 4

Surgical Outcomes and Risks

• The LOTUS randomized controlled trial showed higher remission rates with esomeprazole treatment compared to laparoscopic surgery at 5 years (92% vs 85%) 3
• Surgical complications are higher in elderly patients with comorbidities and in emergency settings 2
• Potential post-surgical complications include dysphagia and gas bloat syndrome 3

Post-Treatment Monitoring

• Patients with Los Angeles B or greater esophagitis, Barrett's esophagus, or peptic stricture require long-term PPI therapy even after surgery 1
• Monitor for recurrent symptoms, dysphagia, weight loss, and deteriorating quality of life after hiatal hernia repair 1
• Endoscopic dilatation is recommended for symptomatic strictures after repair 1

Treatment Algorithm

1. Asymptomatic hiatal hernias: Watchful waiting is appropriate 4
2. Symptomatic hiatal hernias:
   • Begin with lifestyle modifications and PPI therapy
   • Add adjunctive medications as needed
   • Consider surgery if symptoms persist despite optimal medical therapy
   • Choose surgical approach based on hernia size, patient characteristics, and surgeon expertise
