Healthy Life Bariatrics, led by Dr. Babak Moeinolmolki, also known as Dr. Babak Moein, has released a new patient education guide addressing paraesophageal hernias, their underlying anatomy, potential complications, and modern surgical treatment options.
A paraesophageal hernia is a form of hiatal hernia in which part of the stomach—and, in more advanced cases, another abdominal organ—moves through the esophageal opening in the diaphragm and enters the chest.
Unlike a more common sliding hiatal hernia, a paraesophageal hernia may place a substantial portion of the stomach beside or above the esophagus. The condition can remain asymptomatic, cause chronic digestive or respiratory complaints, or occasionally lead to obstruction, gastric volvulus, impaired blood supply, or other urgent complications.
“Paraesophageal hernias vary considerably in size, anatomy, symptoms, and clinical significance,” said Dr. Moein. “The decision to observe or repair the hernia should be based on a complete evaluation rather than the imaging finding alone.”
Understanding the Anatomy of a Paraesophageal Hernia
The diaphragm is the muscular structure separating the abdominal and chest cavities. The esophagus passes through an opening in the diaphragm called the esophageal hiatus before joining the stomach.
Hiatal hernias are categorized according to which anatomical structures have migrated through the hiatus:
Type I: The gastroesophageal junction moves above the diaphragm. This is commonly called a sliding hiatal hernia.
Type II: Part of the stomach moves beside the esophagus while the gastroesophageal junction remains in its normal position.
Type III: Both the gastroesophageal junction and a substantial portion of the stomach move above the diaphragm.
Type IV: The stomach and another abdominal organ, such as the colon or small intestine, migrate into the chest.
Types II, III, and IV are generally included within the paraesophageal hernia category. Type III is frequently encountered in clinical practice.
Why Paraesophageal Hernias Develop
A paraesophageal hernia may form when the tissues surrounding the esophageal hiatus become stretched, weakened, or disrupted.
Potential contributing factors include:
Age-related weakening of connective tissue
Congenital enlargement or weakness of the hiatus
Obesity and chronically elevated abdominal pressure
Pregnancy
Persistent coughing or straining
Repeated heavy lifting
Prior surgery near the diaphragm or esophagus
Abdominal or chest trauma
Certain connective-tissue disorders
In many patients, no single cause can be identified. The condition may develop gradually as supporting tissues become less resistant to pressure over time.
Symptoms Can Extend Beyond Heartburn
Some paraesophageal hernias are discovered incidentally during imaging or endoscopy performed for another reason. Others produce symptoms that may initially be attributed to reflux, aging, pulmonary disease, or dietary intolerance.
Possible symptoms include:
Pressure or pain in the chest or upper abdomen
Difficulty swallowing
Food sticking after swallowing
Regurgitation
Heartburn or acid reflux
Early fullness after eating
Inability to tolerate normal-sized meals
Nausea or vomiting
Shortness of breath
Chronic cough
Fatigue related to iron-deficiency anemia
Gastrointestinal bleeding
Large hernias can compress nearby structures in the chest or interfere with the stomach’s ability to empty normally. Symptoms may worsen after meals, particularly when the stomach becomes distended.
Emergency Warning Signs Require Immediate Evaluation
A paraesophageal hernia can occasionally become incarcerated, obstructed, twisted, or strangulated.
Gastric volvulus occurs when the stomach rotates abnormally. This can obstruct the digestive tract and may compromise blood flow to the stomach.
Patients should seek urgent or emergency medical attention for symptoms such as:
Sudden or severe chest or upper-abdominal pain
Persistent retching or vomiting
Inability to swallow liquids
Progressive abdominal distention
Vomiting blood
Black or tarry stool
Severe shortness of breath
Fainting, weakness, or rapid heart rate
Inability to tolerate food accompanied by worsening pain
These symptoms should not be managed solely through a routine office appointment. Acute incarceration, gastric outlet obstruction, volvulus, ischemia, or perforation may require emergency decompression and surgical treatment.
Diagnosis Begins With a Detailed Clinical Assessment
Evaluation commonly begins with a review of the patient’s symptoms, medical history, prior abdominal or chest operations, and ability to eat and swallow.
The diagnostic process may include several complementary studies.
Upper Gastrointestinal Contrast Study
During an upper gastrointestinal contrast study, the patient drinks a contrast agent while X-ray images are obtained.
The study can demonstrate:
The position of the stomach
The location of the gastroesophageal junction
The size and configuration of the hernia
Rotation or obstruction of the stomach
Esophageal emptying
Reflux or impaired passage of contrast
This dynamic examination can provide information that may not be fully visible during endoscopy alone.
Upper Endoscopy
Upper endoscopy allows the physician to examine the lining of the esophagus, stomach, and upper small intestine.
It may identify:
Esophagitis
Ulceration
Gastritis
Bleeding
Barrett’s esophagus
Narrowing or obstruction
Cameron lesions associated with large hiatal hernias
Other conditions that could explain the patient’s symptoms
Endoscopy can also help exclude tumors or mucosal disease before surgical treatment.
Computed Tomography
A CT scan can provide detailed information about the size and position of the hernia and determine whether organs other than the stomach have migrated into the chest.
CT imaging can be particularly useful in patients with acute symptoms, suspected obstruction, gastric volvulus, unusual anatomy, recurrent hernia, or concern for complications.
Esophageal Function Testing
Esophageal manometry or reflux testing may be recommended selectively.
These studies can assess swallowing function, esophageal motility, acid exposure, and lower-esophageal sphincter performance. The results may influence whether a complete or partial fundoplication is appropriate.
Not every patient requires every available test. The diagnostic plan should be individualized according to symptoms and proposed treatment.
Not Every Paraesophageal Hernia Requires Immediate Surgery
The management of an asymptomatic or minimally symptomatic paraesophageal hernia remains an area of clinical debate.
Current surgical guidance emphasizes shared decision-making. The size and type of hernia, objective evidence of reflux or aspiration, anemia, patient age, frailty, operative risk, and personal preferences should all be considered.
The Society of American Gastrointestinal and Endoscopic Surgeons reports that evidence is insufficient to recommend surgery for every completely asymptomatic patient. Selected patients may reasonably be offered repair, while surveillance may be appropriate for others.
Patients with frailty or substantial medical risk may not benefit from elective surgery in the same way as younger, healthier individuals.
When Surgical Repair May Be Considered
Surgical repair may be recommended when a paraesophageal hernia causes clinically important symptoms or complications.
Possible indications include:
Progressive difficulty swallowing
Persistent regurgitation
Post-meal chest or abdominal pain
Recurrent vomiting
Inability to maintain normal nutrition
Significant shortness of breath related to the hernia
Recurrent aspiration
Chronic bleeding or iron-deficiency anemia
Gastric obstruction
Gastric volvulus
Incarceration or strangulation
Acute or progressive enlargement in an appropriate surgical candidate
The decision should reflect both the burden of symptoms and the risks of the operation.
How Laparoscopic Paraesophageal Hernia Repair Is Performed
Paraesophageal hernia repair is commonly performed through a laparoscopic or robotic minimally invasive approach under general anesthesia.
Several small abdominal incisions provide access for a camera and specialized surgical instruments.
Although the operation is customized, its principal components may include:
Returning the stomach and any other herniated organs to the abdominal cavity.
Separating the hernia sac from the tissues within the chest.
Mobilizing the esophagus to restore an adequate length within the abdomen.
Identifying and protecting nearby structures.
Repairing the enlarged diaphragmatic opening.
Adding an antireflux or fixation procedure when appropriate.
The objective is to restore anatomy, relieve obstruction or pressure, and reduce the likelihood of recurrent migration through the hiatus.
Crural Closure Repairs the Diaphragmatic Opening
The muscular borders of the hiatus are known as the crura. After the stomach is returned to the abdomen, the surgeon typically brings these structures together using sutures.
This portion of the procedure is called a cruroplasty or primary crural closure.
The closure must be secure while avoiding excessive narrowing around the esophagus. A repair that is too loose may increase recurrence risk, while excessive tightness can contribute to postoperative difficulty swallowing.
Fundoplication May Be Added to the Repair
A fundoplication involves wrapping part of the upper stomach around the lower esophagus.
This additional procedure may:
Reinforce the gastroesophageal junction
Reduce postoperative reflux
Help maintain the stomach beneath the diaphragm
Restore components of the natural antireflux barrier
Fundoplication may be complete or partial. The selection can depend on reflux symptoms, esophageal motility, hernia anatomy, age, swallowing function, and surgeon judgment.
Updated SAGES guidance conditionally supports routinely adding fundoplication during hiatal hernia repair, but the recommendation is based on low-certainty evidence. Fundoplication may reduce postoperative reflux while temporarily increasing the risk of dysphagia.
It is therefore not appropriate to assume that exactly the same fundoplication should be performed in every patient.
Gastropexy May Be Appropriate in Selected Cases
Gastropexy secures the stomach within the abdomen to reduce its ability to migrate or rotate.
It may be used as an additional component of a comprehensive repair. In selected older or medically fragile patients, a more limited repair involving reduction and gastropexy may be considered when a lengthy operation would carry excessive risk.
The choice depends on the patient’s anatomy, symptoms, operative risk, and treatment goals.
Mesh Reinforcement Remains an Individualized Decision
Mesh may be placed at the hiatus to reinforce a repair when the opening is unusually large, the tissues are weak, or the closure is under tension.
However, mesh should not be presented as universally necessary or as a guarantee against recurrence.
The 2024 SAGES guideline found the available evidence regarding routine mesh use to be equivocal and did not recommend either routine placement or routine avoidance. Some observational studies suggest a reduction in early recurrence, but randomized trials have not consistently demonstrated a durable advantage. Potential concerns include dysphagia, erosion, scarring, or difficulty during future revision surgery.
The decision should therefore account for:
Hernia size
Tissue quality
Tension across the closure
Previous repair
Type of reinforcement material
Risk of recurrence
Potential mesh-related complications
Minimally Invasive Repair Offers Important Advantages
Compared with traditional open surgery, laparoscopic or robotic repair may offer:
Smaller incisions
Reduced postoperative pain
Less wound morbidity
Earlier mobility
Shorter hospitalization
Faster return to routine activities
Improved visualization of the hiatus
These potential advantages do not make the procedure risk-free.
Possible complications include bleeding, infection, injury to the esophagus or stomach, pneumothorax, dysphagia, gas-bloat symptoms, delayed gastric emptying, recurrent reflux, hernia recurrence, blood clots, pulmonary complications, and the need for additional surgery.
Recovery Is Gradual and Varies Among Patients
Hospitalization after paraesophageal hernia repair varies. Some carefully selected patients may leave within one day, while others require a longer stay because of the size of the repair, age, underlying health, swallowing function, or postoperative symptoms.
Patients are generally encouraged to walk soon after surgery and use pulmonary exercises to reduce respiratory complications.
A typical recovery plan may include:
Early Recovery
During the first several days, patients may experience:
Incisional discomfort
Upper-abdominal tightness
Temporary difficulty swallowing
Shoulder discomfort from laparoscopic gas
Reduced appetite
Fatigue
Abdominal bloating
Pain is usually managed with a combination of non-opioid and, when necessary, prescription medications.
Dietary Progression
Swelling around the repaired hiatus can temporarily restrict the passage of food.
Patients may begin with liquids before progressing to soft or pureed foods. Small bites, thorough chewing, slow eating, and frequent small meals may be recommended.
Carbonated beverages, tough meat, dry bread, and foods likely to become lodged may be restricted during early healing.
The exact dietary schedule differs among surgeons and should be followed according to individualized postoperative instructions.
Activity Restrictions
Walking is generally encouraged, but lifting, forceful straining, and strenuous exercise may be restricted for several weeks.
Patients should avoid driving while taking sedating pain medication or when discomfort limits safe movement.
Many individuals gradually resume routine daily activities over several weeks, but full recovery after a large or complex repair may require longer.
Follow-Up Helps Identify Recurrence or Swallowing Problems
Follow-up visits allow the surgical team to assess:
Dietary tolerance
Swallowing
Reflux symptoms
Pain control
Hydration and nutrition
Incision healing
Pulmonary function
Return to activity
Postoperative imaging or endoscopy may be ordered when symptoms persist or recur.
Radiographic recurrence can occur after paraesophageal hernia repair, but not every recurrent hernia causes symptoms or requires another operation. Management depends on the size of the recurrence, symptoms, anatomical findings, and overall patient health.
