Management of Sliding Hiatus Hernia

Initial Management

The American College of Surgeons recommends initial management with proton pump inhibitors (PPIs) for 4-8 weeks, as most sliding hernias are associated with GERD and respond well to acid suppression, with surgical intervention reserved for those with severe erosive esophagitis, PPI-refractory symptoms, or complications 1, 2, 3
The American College of Surgeons suggests that barium esophagram is essential for complete evaluation of any patient with suspected hiatus hernia, as it provides superior anatomic and functional information compared to endoscopy alone 4

A biphasic esophagram or upper GI series should be performed to assess hernia size, esophageal length, presence of strictures, and gastroesophageal reflux, with reported sensitivity of 88% when combining single and double-contrast techniques, as recommended by the Journal of the American College of Radiology 4
Barium studies are superior to endoscopy for differentiating sliding from paraesophageal hernias, which is critical because surgical approaches differ significantly between these two types, according to the Journal of the American College of Radiology 4
Complete endoscopic evaluation must document the Hill grade of the gastroesophageal flap valve, axial hernia length in centimeters, presence and grade of erosive esophagitis, and Barrett's esophagus if present, as recommended by the American College of Gastroenterology 2, 3, 5

The American College of Gastroenterology recommends starting with single-dose PPI therapy taken 30-60 minutes before a meal for 4-8 weeks as first-line treatment for symptomatic sliding hiatus hernia without alarm features 1, 2
If inadequate response occurs, escalate to twice-daily dosing or switch to a more potent PPI, as recommended by the American College of Gastroenterology 1, 2
Lifestyle modifications should include head of bed elevation and avoiding meals within 3 hours of bedtime, particularly for patients with known hiatus hernia and postprandial or nocturnal symptoms, as suggested by the American College of Gastroenterology 1

Surgery should be considered for patients with proven pathologic GERD who have severe erosive esophagitis, large hernias, or medically refractory symptoms after comprehensive preoperative evaluation, as recommended by the American College of Surgeons 3, 6
High-resolution manometry is mandatory to assess esophageal peristaltic function and exclude achalasia before any surgical intervention, according to the American College of Gastroenterology 3, 6
Laparoscopic fundoplication is the preferred surgical approach with an excellent safety profile and superior outcomes compared to open surgery, as recommended by the American College of Surgeons 3, 6
