GORD and hiatus hernia Flashcards
Briefly describe the pathophysiology of GORD
Lower oesophageal sphincter dysfunction → reflux of gastric contents →
oesophagitis
Three risk factors for GORD?
hiatus hernia smoking alcohol obesity pregnancy drugs
Name two drugs that can induce GORD
CCB, TCAs, anti-ACh, nitrates
Describe two oesophageal symptoms of GORD
Heartburn
Belching
Odonophagia- painful swallowing
Hypersalivation
Describe two extra-oesophageal symptoms of GORD
Nocturnal asthma (lying down)
chronic cough
laryingitis, sinusitis
List two complications of GORD
Oesophagitis: heartburn Ulceration: rarely → haematemesis, melaena, ↓Fe Benign stricture: dysphagia Barrett’s oesophagus Oesophageal adenocarcinoma
Two differential diagnoses for GORD?
Peptic ulcer disease
Oesophagitis (infection, IBD)
Oesophageal carcinoma
Three investigations for suspected GORD?
Bloods: FBC
CXR: hiatus hernia
Ba swallow
24 hr pH testing
When would an oesophago- gastro-duodenoscopy (OGD) be indicated?
>55yrs Symptoms >4wks Dysphagia Persistent symptoms despite Rx Wt. loss
Discuss two conservative options for GORD treatment
Small regular meals >3 hr before bed
Stop smoking and alcohol
Avoid hot drinks and spicy food
Stop drugs: NSAIDs, steroids, CCBs
Name two drugs to treat GORD
PPI- lansoprazole
H2RA- ranitidine
OTC antacids: gaviscon
What are the two types of hiatus hernia?
sliding and rolling
Which hiatus hernia is the most common?
sliding (80%)
Describe the structural abnormality of sliding hernia
Gastro-oesophageal junction slides up into chest
Describe rolling hiatus hernia
Gastro-oesophageal junction remains in abdomen but a
bulge of stomach rolls into chest alongside the
oesophagus
Is GORD more common in sliding or rolling hiatus hernia?
LOS remains intact in rolling hernia, therefore GORD uncommon. Sliding is associated with GORD
List three investigations for GORD
CXR
Ba swallow
OGD
24 hr pH + manometry
Which test is diagnostic of hiatus hernia?
Ba swallow
If patient has hiatus hernia, what would you observe on their CXR?
gas bubble and fluid level in chest
What is manometry?
Manometry measures the strength and muscle coordination of your esophagus when you swallow. During the manometry test, a thin, pressure-sensitive tube is passed through the nose, along the back of the throat, down the esophagus, and into the stomach
What is the management of hiatus hernia?
lose weight, treat for reflux, surgery
Strangulation is a risk of which hernia?
rolling hernia, therefore always perform surgery
Name two organisms that cause infection in the oesophagus
candida albicans (fungus) and HSV (immunocompromised)
Name two cancers of the oesophagus. What are the risk factors associated with these two cancers
squamous carcinoma and adenocarcinoma
SCC- smoking and drinking, adenocarcinoma- GERD and obesity
What histological change arises in Barrett’s oesophagus?
squamous cells become glandular with goblet cells
