Hiatal Hernia

Definition

A hiatal hernia is a condition in which part of the stomach protrudes upward through the diaphragm into the thoracic cavity via the esophageal hiatus.

A hiatal hernia occurs when the upper part of your stomach bulges up through an opening in your diaphragm called the hiatus, into your chest cavity. The diaphragm is a large, dome-shaped muscle that separates your abdomen from your chest. The hiatus is a small opening in the diaphragm through which the esophagus (the tube that carries food from your mouth to your stomach) passes

Types of Hiatal Hernia:

There are two main types of hiatal hernias:

1. Sliding Hiatal Hernia (Type I): This is the most common type, accounting for about 95% of all hiatal hernias. In a sliding hiatal hernia, the gastroesophageal junction (where the esophagus meets the stomach) and a portion of the stomach slide up into the chest through the esophageal hiatus. This movement is often temporary and can occur with changes in body position or pressure in the abdomen.
2. Paraesophageal Hiatal Hernia (Type II, III, and IV): These are less common but potentially more serious. In a paraesophageal hernia, a portion of the stomach (or even other abdominal organs like the colon or spleen) pushes up through the hiatus alongside the esophagus, but the gastroesophageal junction remains in its normal position below the diaphragm.
• Type II (True Paraesophageal): The fundus (top part) of the stomach herniates next to the esophagus.
• Type III (Mixed): A combination of sliding and paraesophageal, where both the gastroesophageal junction and part of the stomach herniate.
• Type IV: A large portion of the stomach and other abdominal organs (colon, small intestine, omentum, spleen) herniate into the chest.

Causes and Risk Factors:

The exact cause of hiatal hernia is often unknown, but several factors can contribute to its development:

• Weakening of the Diaphragm Muscles: Over time, the muscles around the hiatus can weaken, making it easier for the stomach to push through. This weakening can be due to:
• Aging: The incidence increases with age.
• Increased Abdominal Pressure:
• Chronic coughing or sneezing
• Straining during bowel movements
• Heavy lifting
• Vomiting
• Obesity
• Pregnancy
• Trauma: Injury to the diaphragm.
• Congenital Defects: A larger-than-normal hiatus present at birth.
• Smoking: May contribute to muscle weakening.
• Surgery: Previous abdominal or esophageal surgery.

Pathophysiology

• Normally, the diaphragm and lower esophageal sphincter (LES) prevent reflux.
• In hiatal hernia, displacement of stomach weakens LES function.
• This increases gastroesophageal reflux → esophagitis, ulcer, Barrett’s esophagus.

Signs and Symptoms:

Many people with small hiatal hernias experience no symptoms. When symptoms do occur, they are often related to gastroesophageal reflux disease (GERD), as the hernia can compromise the function of the lower esophageal sphincter (LES), which normally prevents stomach acid from flowing back into the esophagus.

Common symptoms include:

• Heartburn: A burning sensation in the chest, often worse after eating, bending over, or lying down.
• Regurgitation: The backward flow of food or sour liquid into the mouth.
• Dysphagia (Difficulty Swallowing): Feeling like food is stuck in the esophagus.
• Belching/Burping: Excessive gas.
• Chest Pain: Can sometimes be mistaken for heart attack pain.
• Shortness of Breath: Particularly with large hernias compressing the lungs.
• Abdominal Pain or Discomfort:
• Nausea and Vomiting:
• Anemia (in severe cases): Due to chronic blood loss from esophageal irritation.

Paraesophageal hernias can also lead to more serious complications such as:

• Obstruction: The stomach can become twisted or trapped, leading to severe pain, nausea, and vomiting.
• Strangulation: The blood supply to the herniated portion of the stomach can be cut off, a medical emergency requiring immediate surgery.
• Bleeding: From irritation or ulceration of the stomach lining.

Diagnosis:

Diagnosis typically involves:

• Barium Swallow (Esophagram): The patient drinks a barium solution, and X-rays are taken to visualize the esophagus and stomach and identify the hernia.
• Upper Endoscopy (EGD - Esophagogastroduodenoscopy): A thin, flexible tube with a camera is inserted down the throat to visualize the esophagus, stomach, and duodenum, allowing for direct visualization of the hernia and any associated inflammation or damage.
• Esophageal Manometry: Measures the pressure and function of the esophageal muscles and LES.
• pH Monitoring: Measures the amount of acid reflux in the esophagus.

Treatment:

Treatment depends on the type and severity of the hernia and the presence of symptoms.

Conservative Management (for symptomatic sliding hernias and mild paraesophageal hernias):

• Dietary Modifications:
• Eat smaller, more frequent meals.
• Avoid trigger foods: fatty foods, spicy foods, acidic foods (citrus, tomatoes), chocolate, peppermint, caffeine, alcohol.
• Avoid eating close to bedtime (at least 2-3 hours before lying down).
• Lifestyle Changes:
• Maintain a healthy weight.
• Elevate the head of the bed by 6-8 inches (using blocks under the bedposts or a wedge pillow).
• Avoid tight clothing around the abdomen.
• Quit smoking.
• Avoid activities that increase abdominal pressure (heavy lifting, straining).
• Medications:
• Antacids: Neutralize stomach acid (e.g., Tums, Rolaids).
• H2-Receptor Blockers: Reduce acid production (e.g., famotidine, ranitidine).
• Proton Pump Inhibitors (PPIs): Block acid production more effectively (e.g., omeprazole, lansoprazole, pantoprazole). These are often the most effective for GERD symptoms.
• Prokinetics: Help strengthen the LES and speed up stomach emptying (less commonly used due to side effects).

Surgical Repair (for severe symptoms, large paraesophageal hernias, or complications):

Surgery, typically Laparoscopic Nissen Fundoplication, involves:

• Reducing the hernia: Pulling the stomach back into the abdominal cavity.
• Repairing the hiatus: Narrowing the opening in the diaphragm.
• Fundoplication: Wrapping the upper part of the stomach (fundus) around the lower esophagus and suturing it in place to create a new, tighter lower esophageal sphincter, which helps prevent reflux.

Prognosis:

With appropriate management, most people with hiatal hernias can effectively control their symptoms. Surgical repair has a high success rate, but recurrence is possible.

Nursing Care Plan for Hiatal Hernia

Patient Profile: A 65-year-old male presenting with chronic heartburn, regurgitation, and occasional difficulty swallowing, diagnosed with a sliding hiatal hernia.

Nursing Diagnoses (NANDA-I):

1. Acute Pain related to reflux of gastric acid into the esophagus as evidenced by verbalization of burning sensation in the chest and epigastric region.
2. Imbalanced Nutrition: Less Than Body Requirements related to impaired ingestion and absorption of nutrients secondary to dysphagia and fear of exacerbating symptoms, as evidenced by reported difficulty swallowing and avoidance of certain foods. (Can also be Risk for Imbalanced Nutrition depending on assessment).
3. Deficient Knowledge regarding disease process, treatment regimen, and lifestyle modifications to prevent symptom recurrence as evidenced by patient's questions about diet and activity restrictions.
4. Risk for Aspiration related to regurgitation of gastric contents into the pharynx/larynx.
5. Anxiety related to unpredictable nature of symptoms and potential for complications as evidenced by patient expressing concern about chest pain.

Nursing Diagnosis 1: Acute Pain

• Related to: Reflux of gastric acid into the esophagus.
• As evidenced by: Verbalization of burning sensation in the chest and epigastric region (heartburn), facial grimacing (if present), restlessness, guarding behavior (if present).

Desired Outcome (SMART Goal): Patient will report a reduction in pain intensity from a current level of (e.g., 6/10) to (e.g., 2/10) or less within 24-48 hours, and effectively manage pain using prescribed medications and lifestyle modifications.

Nursing Interventions with Rationale:

Nursing Intervention	Rationale
Assessment:
Assess pain characteristics: location, intensity (0-10 scale), quality (burning), onset, duration, and precipitating/alleviating factors.	Provides baseline data to evaluate the effectiveness of interventions and guides appropriate treatment strategies.
Monitor for signs of complications like GI bleeding (melena, hematemesis).	Chronic irritation can lead to esophageal erosion or ulceration, causing bleeding.
Planning & Implementation:
Administer prescribed antacids, H2-receptor blockers, or PPIs as ordered, explaining their purpose and administration guidelines (e.g., take PPIs 30-60 min before meals).	Medications reduce gastric acid production or neutralize existing acid, thereby decreasing esophageal irritation and pain. Correct administration maximizes effectiveness.
Elevate the head of the bed 6-8 inches (using blocks or a wedge pillow) for sleep and rest.	Gravity helps prevent reflux of gastric contents into the esophagus, especially at night when lying flat.
Advise patient to avoid lying down for at least 2-3 hours after meals.	Allows time for gastric emptying, reducing the likelihood of reflux.
Instruct patient to eat smaller, more frequent meals rather than large, infrequent ones.	Large meals distend the stomach and increase intragastric pressure, promoting reflux. Smaller meals reduce the volume of contents available for reflux.
Educate patient on avoiding trigger foods: fatty foods, spicy foods, acidic foods (citrus, tomatoes), chocolate, peppermint, caffeine, alcohol.	These foods either relax the LES, increase acid production, or directly irritate the esophageal mucosa, worsening symptoms.
Encourage cessation of smoking.	Nicotine relaxes the LES and may increase acid production.
Advise avoiding tight clothing around the abdomen.	Increases intra-abdominal pressure, which can push gastric contents up through the hiatus.
Recommend weight loss if the patient is overweight or obese.	Excess abdominal fat increases intra-abdominal pressure, exacerbating the hernia and reflux symptoms.
Provide emotional support and encourage relaxation techniques (e.g., deep breathing, distraction).	Anxiety can exacerbate pain perception. Relaxation can help the patient cope with discomfort.
Evaluation:
Reassess pain intensity and characteristics. Observe for changes in behavior (e.g., less grimacing, improved sleep).	Determines if interventions are effective and if further adjustments are needed.
Patient demonstrates understanding and adherence to medication regimen and lifestyle modifications.	Indicates successful patient education and commitment to managing symptoms.

Nursing Diagnosis 2: Deficient Knowledge

• Related to: Lack of exposure/unfamiliarity with new information about disease process, treatment regimen, and lifestyle modifications.
• As evidenced by: Patient asking questions about diet, activity restrictions, purpose of medications, and expressed confusion about how to manage symptoms at home.

Desired Outcome (SMART Goal): Patient will verbalize understanding of hiatal hernia, prescribed medications, necessary dietary and lifestyle modifications, and signs/symptoms to report to the healthcare provider within 24 hours prior to discharge.

Nursing Interventions with Rationale:

Nursing Intervention	Rationale
Assessment:
Assess patient's current knowledge level regarding hiatal hernia, its causes, symptoms, and treatment options.	Identifies specific knowledge gaps and allows for individualized teaching.
Identify patient's preferred learning style (visual, auditory, kinesthetic) and readiness to learn.	Tailoring teaching methods to the patient's preferences enhances comprehension and retention.
Planning & Implementation:
Provide clear, concise explanations of hiatal hernia, using lay terms, including its pathophysiology and how it causes symptoms. Use visual aids if available.	Improves understanding of the disease and fosters patient engagement in their care. Visual aids can enhance learning.
Educate patient thoroughly on all prescribed medications: name, purpose, dosage, frequency, administration instructions (e.g., with/without food, time of day), and potential side effects.	Ensures safe and effective medication use and promotes adherence.
Provide a comprehensive list of dietary recommendations (e.g., small, frequent meals; avoid trigger foods; eat slowly) and foods to avoid. Explain why these recommendations are important.	Empowers the patient to make informed dietary choices that can significantly impact symptom management.
Instruct patient on lifestyle modifications: elevating the head of the bed, avoiding lying down after meals, weight management, avoiding tight clothing, smoking cessation.	These modifications reduce intragastric pressure and prevent reflux, playing a crucial role in symptom control.
Discuss signs and symptoms that warrant immediate medical attention (e.g., severe chest pain, persistent vomiting, difficulty swallowing, signs of GI bleeding like black stools or vomiting blood).	Enables early detection and intervention for potential complications, preventing more serious health issues.
Provide written educational materials (e.g., pamphlets, discharge instructions) for reinforcement.	Serves as a reference for the patient and family at home, reinforcing verbal instructions.
Encourage the patient and family to ask questions and express concerns. Answer questions honestly and thoroughly.	Promotes an open dialogue, clarifies misunderstandings, and reduces anxiety.
Evaluation:
Ask the patient to "teach back" or demonstrate their understanding of the information provided (e.g., "Can you tell me in your own words how you will take your medication?").	Assesses retention and comprehension of information; identifies areas needing further clarification or re-teaching.
Observe patient's adherence to dietary and lifestyle recommendations during hospitalization and on follow-up visits.	Provides objective evidence of learning and commitment to self-management.

Nursing Diagnosis 3: Risk for Aspiration

• Related to: Regurgitation of gastric contents into the pharynx/larynx.
• As evidenced by: (This is a risk diagnosis, so evidence would be risk factors such as reported regurgitation, dysphagia).

Desired Outcome (SMART Goal): Patient will remain free from aspiration as evidenced by clear breath sounds, absence of cough or choking during/after meals, and maintenance of normal respiratory rate and rhythm throughout hospitalization.

Nursing Interventions with Rationale:

Nursing Intervention	Rationale
Assessment:
Assess for signs of aspiration: coughing, choking, hoarseness, sudden onset of dyspnea, crackles or rhonchi on auscultation, low-grade fever.	Early detection of aspiration allows for prompt intervention to prevent aspiration pneumonia.
Evaluate swallowing ability, including the presence of dysphagia or frequent regurgitation.	Identifies patients at higher risk for aspiration.
Planning & Implementation:
Elevate the head of the bed to at least 30-45 degrees, especially during and after meals, and for sleep.	Gravity helps prevent reflux and gravitational drainage of secretions, reducing the risk of aspiration.
Instruct patient to remain in an upright position for at least 2-3 hours after meals.	Allows for gastric emptying and reduces the likelihood of food and acid refluxing into the esophagus and airway.
Encourage slow eating and thorough chewing of food.	Reduces the size of food particles, making them easier to swallow and less likely to become lodged.
Provide small, frequent meals and limit fluid intake during meals if dysphagia is present (consult with speech therapy).	Reduces the volume of food/fluid in the stomach at one time, decreasing the risk of reflux and aspiration.
Avoid thin liquids, or thicken liquids as recommended by a speech-language pathologist, if dysphagia is a significant issue.	Thin liquids are more difficult to control and more easily aspirated than thicker consistencies.
Ensure oral hygiene is maintained, especially before and after meals.	Reduces the bacterial load in the mouth, which, if aspirated, could contribute to aspiration pneumonia.
Administer prescribed anti-reflux medications (PPIs, H2 blockers) as ordered.	Reducing gastric acid production minimizes the damage to lung tissue if aspiration does occur.
Have suction equipment readily available if the patient is at high risk for aspiration.	Allows for immediate removal of aspirated material from the airway, preventing further compromise.
Evaluation:
Monitor respiratory status regularly (rate, rhythm, depth, breath sounds).	Continued assessment ensures that the interventions are effective in preventing aspiration and identifies any subtle signs of compromise.
Patient demonstrates understanding and adherence to positioning and feeding precautions.	Indicates successful patient education and commitment to self-management to prevent aspiration.

Nursing Diagnosis 4: Imbalanced Nutrition: Less Than Body Requirements (or Risk for)

• Related to: Impaired ingestion and absorption of nutrients secondary to dysphagia, pain with eating, and fear of exacerbating symptoms.
• As evidenced by: Reported difficulty swallowing, avoidance of certain foods, potential weight loss (if applicable), and verbalization of fear of eating due to reflux.

Desired Outcome (SMART Goal): Patient will maintain current weight or demonstrate a gain of (e.g., 0.5 kg/week ) and report improved comfort during and after meals within 1 week.

Nursing Interventions with Rationale:

Nursing Intervention	Rationale
Assessment:
Assess patient's dietary intake, usual eating patterns, food preferences, and any reported food intolerances or trigger foods.	Provides a baseline for nutritional status and helps identify specific factors contributing to nutritional deficits or discomfort.
Monitor weight regularly (e.g., daily or weekly), and assess for signs of dehydration (poor skin turgor, dry mucous membranes).	Tracks nutritional status and identifies potential fluid imbalances, which can occur if the patient is fearful of drinking due to reflux.
Assess for signs and symptoms of dysphagia, including coughing/choking during meals, prolonged eating time, or food "sticking."	Identifies the degree of swallowing difficulty and guides appropriate interventions, including speech therapy consultation.
Planning & Implementation:
Collaborate with a registered dietitian to develop an individualized meal plan that is nutritionally adequate, easy to swallow, and minimizes reflux.	Ensures that the patient receives sufficient calories and nutrients while avoiding foods that exacerbate symptoms.
Encourage small, frequent meals throughout the day (e.g., 6 small meals) rather than 3 large ones.	Reduces gastric distention and the amount of food available for reflux at any one time, making eating more comfortable.
Offer easily digestible foods that are low in fat, non-acidic, and non-spicy. Provide soft, pureed, or liquid diets as needed based on swallowing ability.	Minimizes irritation to the esophagus and reduces the workload on the digestive system, making eating less painful and reducing reflux potential.
Ensure a quiet, relaxed eating environment, and encourage the patient to eat slowly, chew thoroughly, and take small bites.	Reduces stress and promotes better digestion, lessening the likelihood of reflux and dysphagia-related discomfort.
Administer prescribed anti-reflux medications (PPIs, H2 blockers) before meals as indicated to reduce pain and discomfort associated with eating.	Optimizes the effectiveness of medication to control acid reflux, making meals more tolerable and encouraging intake.
Elevate the head of the bed during and for at least 2-3 hours after meals.	Gravity assists in keeping gastric contents in the stomach and minimizes reflux.
Offer oral hygiene before and after meals.	Improves appetite and comfort, and prevents bacterial overgrowth.
Evaluation:
Monitor patient's weight, food intake, and reports of comfort after meals.	Determines if the nutritional interventions are effective in improving nutritional status and reducing symptoms.
Patient demonstrates understanding and adherence to the recommended diet and eating patterns.	Indicates successful patient education and commitment to self-management for optimal nutrition.

Nursing Diagnosis 5: Anxiety

• Related to: Unpredictable nature of symptoms, potential for complications, and unfamiliarity with disease management.
• As evidenced by: Verbalization of nervousness, restlessness, repetitive questions about chest pain and potential complications, sleep disturbance.

Desired Outcome (SMART Goal): Patient will report a decrease in anxiety level (e.g., from 7/10 to 3/10 or less) and demonstrate effective coping strategies within 48 hours.

Nursing Interventions with Rationale:

Nursing Intervention	Rationale
Assessment:
Assess patient's anxiety level using a scale (e.g., 0-10) and observe for non-verbal cues (restlessness, agitation, rapid speech, facial tension).	Provides a baseline for evaluating the effectiveness of interventions and identifies the severity of anxiety.
Explore the patient's specific concerns regarding their hiatal hernia (e.g., fear of heart attack due to chest pain, fear of surgery).	Tailors interventions to address the patient's unique anxieties and misconceptions.
Planning & Implementation:
Provide accurate, consistent, and clear information about the hiatal hernia, its symptoms, and the treatment plan. Explain that chest pain from reflux is different from cardiac pain.	Knowledge reduces fear of the unknown and can alleviate anxiety, especially regarding symptoms that mimic serious conditions.
Encourage the patient to express feelings, fears, and concerns openly in a non-judgmental environment.	Allows for emotional release and helps the nurse understand the patient's psychological response to the illness.
Teach and encourage relaxation techniques such as deep breathing exercises, guided imagery, or progressive muscle relaxation.	Provides the patient with tools to actively manage their anxiety and promote a sense of control.
Ensure the patient has a clear understanding of the medication regimen and how to manage symptoms at home.	A sense of control over symptom management significantly reduces anxiety.
Encourage participation in care decisions to the extent possible.	Promotes a sense of autonomy and control, which can mitigate feelings of helplessness and anxiety.
Limit environmental stimuli when the patient is anxious (e.g., dim lights, reduce noise).	A calm environment can help reduce external stressors that contribute to anxiety.
Provide consistent nursing care and build a trusting relationship with the patient.	A trusting relationship fosters open communication and provides emotional security for the patient.
Evaluation:
Reassess anxiety level using the same scale and observe for a decrease in physical and behavioral manifestations of anxiety.	Determines if interventions are effective and if further support is needed.
Patient reports feeling calmer, sleeping better, and using coping strategies effectively.	Indicates successful anxiety reduction and improved emotional well-being.
