From the Guidelines
Laparoscopic repair with mesh reinforcement is the recommended surgical approach for hiatal hernias, especially for large hernias or those that are symptomatic and do not respond to medication, as it offers a minimally invasive approach with shorter recovery time and reduced morbidity compared to open surgery 1.
Diagnosis of Hiatal Hernias
Diagnosis of hiatal hernias typically involves an upper endoscopy, barium swallow X-ray, or CT scan. These diagnostic tools help identify the presence and type of hernia, which are crucial for determining the appropriate management strategy. Many small hiatal hernias cause no symptoms and require no treatment, but symptomatic cases need a comprehensive approach.
Management Options
For symptomatic cases, management includes lifestyle modifications such as weight loss, avoiding large meals, not lying down after eating, and elevating the head of the bed. Medications include antacids for occasional symptoms, H2 blockers (ranitidine 150mg twice daily, famotidine 20mg twice daily), and proton pump inhibitors (omeprazole 20-40mg daily, pantoprazole 40mg daily) for more persistent acid reflux.
Surgical Intervention
Surgery becomes necessary for large hernias, especially paraesophageal types, or when symptoms don't respond to medication. The choice of surgical technique may depend on factors such as the size of the hernia, the presence of gastroesophageal reflux, and the patient's overall health status. Laparoscopic fundoplication, which may be tailored to the patient's specific needs (e.g., partial fundoplication for patients with esophageal hypomotility), and magnetic sphincter augmentation are effective surgical options for patients with proven GERD, as highlighted in recent clinical practice updates 1.
Considerations for Surgical Approach
The decision to perform a specific type of fundoplication (e.g., Nissen vs. Toupet) or to use mesh reinforcement should be based on the individual patient's condition and the surgeon's expertise. For instance, Nissen fundoplication and Toupet fundoplication have similar effects on restoring the mechanical gastroesophageal barrier against gastric reflux, but the choice between them may depend on factors such as the risk of postoperative dysphagia 1.
Postoperative Care and Complications
Recovery from laparoscopic surgery typically takes 2-3 weeks, while open surgery may require 4-6 weeks. Complications of untreated large hernias can include strangulation, where blood supply is cut off, requiring emergency surgery. Therefore, timely and appropriate management of hiatal hernias is crucial to prevent such complications and improve patient outcomes.
Recent Guidelines and Recommendations
Recent guidelines and position papers, such as those from the World Journal of Emergency Surgery 1, emphasize the importance of a personalized approach to the management of hiatal hernias, considering the patient's specific condition, the type and size of the hernia, and the presence of complications such as gastroesophageal reflux. These guidelines support the use of laparoscopic repair with mesh reinforcement as a standard approach for many patients, highlighting its benefits in terms of reduced morbidity and faster recovery.
From the Research
Diagnosis of Hiatal Hernias
- Hiatal hernias are often found incidentally on radiographic or endoscopic studies 2
- Symptoms of hiatal hernia are related to reflux disease, as well as intrathoracic compression symptoms due to the dislodgement of intrathoracic organs into the mediastinum 3
- Patients with paraesophageal hernias (PEH) have a large variety of symptoms, such as chest pain, dyspnea, regurgitation, iterative pneumonia, and iron-deficiency anemia 4
Management Options for Hiatal Hernias
- Asymptomatic hiatal and paraesophageal hernias can be managed with watchful waiting, as they become symptomatic and necessitate repair at a rate of 1% per year 2
- Symptomatic hiatal hernias and those with confirmed reflux disease require operative repair with an anti-reflux procedure 2
- Operative management is necessary for sliding hernia with reflux disease and for symptomatic PEH 4
- Laparoscopic repair of paraesophageal hiatal hernias is a viable alternative to open surgical approaches, with equivalent control of the herniation and the patient's symptoms 5
- Surgical techniques for hiatal hernia repair include open surgery, various laparoscopic procedures, transoral incisionless fundoplication, and magnetic sphincter augmentation (MSA) 6
Surgical Techniques for Hiatal Hernia Repair
- Key operative steps for hiatal hernia repair include reduction and excision of hernia sac, 3 cm of intraabdominal esophageal length, crural closure with mesh reinforcement, and an anti-reflux procedure 2
- Laparoscopic Nissen fundoplication is often considered the standard for treating gastroesophageal reflux disease-related hiatal hernia due to its effectiveness 6
- Other procedures, such as Toupet and Dor fundoplications, may be suited for patients with specific conditions, such as impaired esophageal motility 6
- Newer approaches, including the MSA system and mesh repair, focus on patient-specific treatments to achieve the best outcomes 6
