Management of Hiatal Hernia in Obese Patients

Diagnostic Considerations

The patient presents with dysphagia relieved by belching, suggesting a mechanical obstruction at the gastroesophageal junction, according to the American Gastroenterological Association 1
Barium study confirms hiatal hernia with gastroesophageal junction above the diaphragm and part of the stomach herniated parallel to the esophagus, as reported by the World Journal of Emergency Surgery 2
These findings are consistent with a paraesophageal hiatal hernia requiring surgical intervention, as stated by the World Journal of Emergency Surgery 2, 3

Roux-en-Y gastric bypass is the preferred primary anti-reflux intervention in obese patients with hiatal hernia, recommended by the American College of Gastroenterology 1
Laparoscopic fundoplication would be the standard approach for non-obese patients, according to the American College of Gastroenterology 1, 4
Type of fundoplication can be tailored based on esophageal motility, as suggested by the American College of Gastroenterology 1

Partial fundoplication (Toupet) is preferred in patients with esophageal hypomotility or impaired peristaltic reserve when there is concern for postoperative dysphagia, recommended by the American College of Gastroenterology 1
Nissen fundoplication (360° wrap) remains the gold standard for durable relief of GERD symptoms but carries higher risk of postoperative dysphagia, as reported by the Society of American Gastrointestinal and Endoscopic Surgeons 5

High-resolution manometry to assess esophageal peristaltic function and exclude achalasia, recommended by the American College of Gastroenterology 1, 5
Complete endoscopic evaluation to document severity of any esophagitis, suggested by the American Society for Gastrointestinal Endoscopy 5
Confirmation of pathologic GERD is necessary before proceeding with invasive anti-reflux procedures, as stated by the American College of Gastroenterology 1

Laparoscopic approach is strongly recommended for stable patients, according to the Society of American Gastrointestinal and Endoscopic Surgeons 2, 5
Anatomical repair should include closure of the diaphragmatic hiatus using non-absorbable sutures, as reported by the World Journal of Emergency Surgery 2, 3
For larger defects (>3 cm), mesh reinforcement may be necessary to prevent recurrence, recommended by the World Journal of Emergency Surgery 2, 3

Dysphagia (more common with Nissen fundoplication), as reported by the Society of American Gastrointestinal and Endoscopic Surgeons 5
Recurrent reflux, as stated by the American College of Gastroenterology 5

Endoscopic surveillance to monitor healing and detect potential complications, recommended by the American Society for Gastrointestinal Endoscopy 5
Monitoring for symptom recurrence, suggested by the American College of Gastroenterology 1, 5
