What is the appropriate treatment approach for a hiatal hernia, including lifestyle modifications, medications, and indications for surgery?

Treatment of Hiatal Hernia

For symptomatic hiatal hernias with GERD, initiate proton pump inhibitors (PPIs) 30-60 minutes before meals combined with lifestyle modifications, and reserve laparoscopic surgical repair with fundoplication for patients with confirmed pathologic reflux who fail optimized medical therapy. 1, 2

Initial Conservative Management

Lifestyle Modifications (First-Line for All Symptomatic Patients)

• Weight reduction in obese patients decreases intra-abdominal pressure and improves symptoms 2, 3
• Elevate the head of the bed 15-20 cm to prevent nocturnal reflux 2, 3
• Avoid heavy meals within 3 hours of bedtime to reduce nocturnal symptoms 2, 3
• Implement diaphragmatic breathing techniques to strengthen the anti-reflux barrier and reduce diaphragmatic irritation 2, 3

Medical Therapy

• PPIs are first-line pharmacotherapy, administered 30-60 minutes before meals to maximize acid suppression 2, 3
• Start with single-dose PPI for 4-8 weeks in patients with typical reflux symptoms without alarm features 1
• Escalate to twice-daily dosing or switch to more potent acid suppression if symptoms persist after initial trial 1, 3
• Alginate-based antacids provide relief for breakthrough symptoms, particularly effective in patients with known hiatal hernia 3
• H2 antagonists may address nocturnal symptoms, though tachyphylaxis limits long-term use 3
• Baclofen can be considered for predominant regurgitation or belching, despite side effect limitations 3

Diagnostic Evaluation

When to Pursue Objective Testing

• Obtain objective reflux testing when planning long-term PPI therapy to establish definitive GERD diagnosis 1
• Upper GI series with double contrast or biphasic esophagram is the most appropriate examination to evaluate hernia size and type 2
• Upper endoscopy is warranted for PPI non-response, alarm symptoms, isolated extra-esophageal symptoms, or Barrett's esophagus screening criteria 1

Preoperative Assessment (Required Before Any Surgical Intervention)

• High-resolution manometry to assess esophageal peristaltic function and exclude achalasia 1, 2, 4
• 24-hour ambulatory pH-impedance monitoring off PPI to assess esophageal acid exposure and confirm pathologic GERD 1, 2, 4
• Distinguish between sliding (Type I) and paraesophageal hernias (Types II-IV) as surgical approach differs 2, 5

Indications for Surgical Repair

Absolute Indications

• Confirmed pathologic GERD with inadequate response to optimized medical therapy 1, 4
• Symptomatic paraesophageal hernias due to risk of incarceration and volvulus 6, 7, 5
• Acute presentation with hernia incarceration (severe epigastric pain, retching, organ ischemia) requires urgent intervention 1, 5

Watchful Waiting Appropriate For

• Asymptomatic hiatal and paraesophageal hernias become symptomatic at only 1% per year 6

Surgical Approach

Standard Laparoscopic Technique (Preferred)

Laparoscopic Nissen fundoplication is the gold standard for hiatal hernia with GERD 2, 6, 7

Key operative steps include: 6, 5

• Reduction and excision of hernia sac
• Achieve 3 cm of intra-abdominal esophageal length
• Crural closure with mesh reinforcement
• Anti-reflux procedure (fundoplication)

Surgical Modifications Based on Patient Factors

• Partial fundoplication preferred in patients with known esophageal hypomotility or impaired peristaltic reserve to minimize postoperative dysphagia 1, 2
• Magnetic sphincter augmentation is an alternative option, often combined with crural repair 1
• Mesh reinforcement of hiatal closure reduces hernia recurrence rates 7, 5
• Mesh should overlap defect edge by 1.5-2.5 cm, particularly for defects >8 cm or area >20 cm² 1

Alternative Approaches for Specific Populations

• Transoral incisionless fundoplication is an endoscopic option for carefully selected patients with GERD in the absence of hiatal hernia 1, 3
• Roux-en-Y gastric bypass is the preferred primary anti-reflux intervention in obese patients with hiatal hernia 1, 4
• Avoid sleeve gastrectomy in patients with significant reflux symptoms as it can worsen GERD 1, 4
• Gastropexy and gastrostomy placement serve as alternative procedures when repairs are not amenable to standard key steps 1, 6

Approach Selection for Unstable Patients

• Laparotomy approach for unstable patients with complicated diaphragmatic hernia 1
• Minimally invasive approach for stable patients with complicated hernias 1
• Damage control surgery should be considered in critically unstable patients when the diaphragm cannot be closed 1

Long-Term Management and Follow-Up

PPI Titration Strategy

• Titrate PPI to lowest effective dose when adequate symptom response achieved 1, 3
• Long-term PPI therapy required without dose reduction for erosive esophagitis grade B or higher, Barrett's esophagus, or peptic stricture 2, 3
• Severe GERD with large hiatal hernia requires indefinite PPI therapy 3

Monitoring for Treatment Failure

• Systematic reevaluation and adjustment of treatment when response is adequate 2, 3
• Surveillance with endoscopy and esophageal physiological studies for persistent symptoms 2, 3
• Consider neuromodulation with low-dose antidepressants for esophageal hypersensitivity or hypervigilance 1, 3

Common Pitfalls to Avoid

• Do not perform anti-reflux surgery without confirming pathologic GERD through objective testing, as this leads to poor outcomes 1, 4
• Do not skip preoperative manometry, as undiagnosed achalasia will result in severe postoperative dysphagia 1, 4
• Avoid tackers near the pericardium during mesh fixation due to cardiac complication risk 1
• Do not assume all symptomatic patients require surgery—optimize medical therapy first, as many respond well to lifestyle and pharmacotherapy 1, 2
• In patients without erosive disease and physiologic acid exposure, consider functional esophageal disorder and pursue neuromodulation or behavioral interventions rather than escalating acid suppression 1
