Hiatus Hernia Flashcards

1
Q

A hiatus hernia (HH) refers to when the there is a protrusion of part of the stomach through the diaphragmatic hiatus into the thoracic cavity. Which of the following is NOT an inherent risk factor for HH?

1 - Age
2 - Gender
3 - Lifestyle
4 - Genetics

A

3 - Lifestyle
This is an acquired risk factor

  • Age = HH increase with age
  • Gender = more likely in women

Q

Which of the following is NOT an acquired risk factor for a Hiatus hernia?

1 - Iatrogenic
2 - Mechanical stressor
3 - Lifestyle
4 - Genetics

A

4 - Genetics
This is an inherent risk factor

  • Lifestyle factors = Obesity and smoking
  • Mechanical stressors = heavy lifting and activity that increases intra-abdominal 0 Surgery = manipulation or disruption of the gastroesophageal junction can result in a hiatal hernia.

Q

There are 4 main types of hiatus hernia (HH). Which of these matches the following description?

  • rare accounts for 5% HH, the gastroesophageal junction is in normal position, but stomach herniates beside it. Increased risk of gastric volvulus and strangulation

1 - Pure Paraesophageal Hernia
2 - Complex or Giant Paraesophageal Hernia
3 - Sliding Hiatus Hernia
4 - Mixed Hiatus Hernia.

A

1 - Pure Paraesophageal Hernia

Classed as Type II

Q

There are 4 main types of hiatus hernia (HH). Which of these matches the following description?

  • both the gastroesophageal junction and part of the stomach herniate through the esophageal hiatus. Accounts for 5% of HH and increases the risk of gastric volvulus and strangulation.

1 - Pure Paraesophageal Hernia
2 - Complex or Giant Paraesophageal Hernia
3 - Sliding Hiatus Hernia
4 - Mixed Hiatus Hernia

The most common type, accounting for more than 90% of cases. It involves a sliding movement of the gastroesophageal junction (GEJ) above the diaphragm alongside a portion of the stomach.
Clinically, it is often associated with gastroesophageal reflux disease (GERD).

Type IV: Complex or Giant Paraesophageal Hernia

A

4 - Mixed Hiatus Hernia

Classed as a type III HH

Q

There are 4 main types of hiatus hernia (HH). Which of these matches the following description?

  • Involves herniation of other organs such as colon, spleen or small intestine along with a substantial portion of stomach through esophageal hiatus. Rare, but requires urgent surgical intervention due to high risk complications like strangulation and perforation.

1 - Pure Paraesophageal Hernia
2 - Complex or Giant Paraesophageal Hernia
3 - Sliding Hiatus Hernia
4 - Mixed Hiatus Hernia

A

2 - Complex or Giant Paraesophageal Hernia

Classed as a type IV HH

Q

All of the following are common clinical features of a hiatus hernia, but which is by far the most common feature?

1 - Gastro-oesophageal Reflux
2 - Chest Pain
3 - Respiratory Symptoms
4 - Anaemia
5 - Dyspepsia
6 - Oesophagitis

A

1 - Gastro-oesophageal Reflux

  • Chest Pain = similar to angina, and worse when lying down or bending over
  • Respiratory Symptoms = reduced thoracic space for breathing
  • Anaemia - small volume of chronic bleeding
  • Dyspepsia - stomach ache
  • Oesophagitis = continued reflux can lead to inflammation

Q

Do all patients with a hiatus hernia (HH) present with symptoms?

Q

Management of a hiatus hernia can be divided into:

Lifestyle modifications
- Reduce food and drink that exacerbate symptoms
- Weight loss reduces intra-abdominal pressure
- Bed elevation
- Smoking cessation

Medical management
- PPI are first-line therapy for symptomatic relief and healing esophagitis in patients with associated GERD.
- H2 receptor antagonists may be considered if PPIs are not tolerated or contraindicated.
- Prokinetic agents may help with motility disorders

Surgical management
- Laparoscopic fundoplication is the procedure of choice f
- Hernia repair with mesh may be considered in large paraesophageal hernias to reduce the risk of recurrence.
- Emergency surgery is indicated for complications such as strangulation or perforation.

A

Treatment is ultimately decided based on the:

  • patients symptoms
  • patients comorbidities and risk factors
  • severity of the HH

Q

Diagnosis is a combination of history, examination and investigations. What is thew 1st line test for diagnosing a hiatus hernia (HH)?

1 - chest X-ray
2 - endoscopy
3 - barium swallow
4 - gastroscopy
5 - pH Monitoring
6 - High Resolution Manometry (HRM) and Impedance-pH Monitoring

A

3 - barium swallow
Gives information about the size, type and any associated complications of the HH

BUT gastroscopy is GOLD standard

pH Monitoring = GORD
High Resolution Manometry (HRM) and Impedance-pH Monitoring = used if diagnosis is inconclusive
