Hiatus hernia
๐ช Hiatus hernia occurs when part of the stomach pushes through the diaphragm into the chest cavity.
Often silent ๐คซ, but it may cause reflux ๐ฅ (GORD) and long-term complications.
Early recognition + treatment are key to preventing oesophageal damage.
๐ About Hiatus Hernia
Hiatus hernia = stomach protrusion through the oesophageal hiatus of the diaphragm.
Two main types:
- โก๏ธ Sliding (95%): Gastro-oesophageal junction + stomach slide into thorax.
- โก๏ธ Paraesophageal: Part of stomach herniates beside oesophagus โ risk of strangulation โ ๏ธ.
- Weakened diaphragmatic sphincter.
- Lower oesophagus + stomach rise into thorax.
- Common anatomical variation affecting digestion ๐ฝ๏ธ.
โ๏ธ Aetiology
- ๐ฅ Chronic GORD: Weakens diaphragm over time.
- โ๏ธ Obesity: Increases intra-abdominal pressure.
- ๐ Age: Tissue weakening with age.
- ๐งฌ Genetics: Familial tendency.
- ๐คฐ Pregnancy: Raised intra-abdominal pressure.
- ๐ค Trauma: Abdominal injury weakening diaphragm.
๐ฉโโ๏ธ Clinical Presentation
- ๐คซ Asymptomatic: Commonly found incidentally.
- ๐ฅ Reflux symptoms: Heartburn, regurgitation, sour taste.
- โค๏ธ Chest pain: May mimic angina โ rule out cardiac causes.
- ๐ฅด Dysphagia: Red flag ๐จ โ consider malignancy.
- ๐จ Belching/bloating: Excessive gas + discomfort.
- ๐ค Hoarseness/sore throat: Reflux affecting vocal cords.
๐ก Clinical Pearl:
Hiatus hernia can mimic angina โค๏ธ. Always exclude cardiac disease in chest pain patients.
Dysphagia + weight loss โ ๏ธ โ think oesophageal cancer, not just reflux.
๐งพ Differential Diagnosis
- ๐ฅ GORD without hernia
- โค๏ธ Angina pectoris (ischaemic chest pain)
- ๐ฆ Oesophageal cancer
- ๐ Achalasia (motility disorder)
- ๐ฉน Peptic ulcer disease
- โ ๏ธ Hiatal abscess (rare)
๐ Investigations
- ๐ฉธ Bloods: FBC (anaemia from bleeding), U&E, LFTs.
- ๐ผ๏ธ Barium swallow: Visualises herniation + function.
- ๐ก OGD (endoscopy): Detect oesophagitis, Barrettโs, malignancy.
- ๐ฉป CXR: Retrocardiac mass clue.
- ๐ Manometry: Assesses motility if dysphagia.
- ๐ 24h pH monitoring: Quantifies reflux.
๐ ๏ธ Management
- ๐ Lifestyle: Weight loss, avoid late meals, smaller portions, elevate bedhead, avoid trigger foods (coffee, alcohol, chocolate, spicy foods).
- ๐ Pharmacological:
- Antacids โ quick relief.
- PPIs / H2 blockers โ reduce acid.
- Prokinetics โ improve emptying.
- ๐ง Endoscopic therapy: Endoscopic fundoplication in selected cases.
- ๐ช Surgery: For refractory or complicated hernia (Nissen fundoplication, hiatoplasty, laparoscopic repair).
๐ Case Example
๐ฉ A 58-year-old overweight woman (BMI 32) presents with 6 months of heartburn ๐ฅ, worse at night, with occasional chest pain โค๏ธ.
She worries about her heart, but ECG is normal.
OGD shows erosive oesophagitis and a sliding hiatus hernia.
โ
Management: Lifestyle advice (weight loss, avoid late meals), PPI therapy, follow-up.
Surgery considered only if refractory or complications develop.
๐ Prognosis
- โ
Asymptomatic: Often requires no treatment.
- ๐ฅ Symptomatic: Controlled well with PPIs + lifestyle.
- โ ๏ธ Complicated: Surgery needed for strangulation or severe reflux damage.
- ๐
Follow-up: Long-term to monitor for Barrettโs oesophagus or malignancy risk.
