LOS tone
Indications [3]
- Oesophageal manometry involves the passage of a thin, pressure sensitive catheter to the lower oesophagus to assess the function of the upper and lower oesophageal sphincter (LOS) and assess oesophageal motility. The normal LOS tone is between 10–30 mmHg.
Indications - Investigation of dysphagia and non-cardiac chest pain.
- Diagnosis and ongoing assessment of patients with GORD.
- Preoperative evaluation of patients with GORD in whom fundoplication or alternative surgery is being considered, to select patients likely to benefit.

Forms of dysphagia
Dysphagia can be classified as:
* Oropharyngeal dysphagia: difficulty initiating swallow, which may be accompanied by coughing, choking, regurgitation or aspiration.
* Oesophageal dysphagia: a sensation of food getting stuck in the oesophagus several seconds after initiating a swallow.

What does constant and progressive dysphagia suggest
Malignancy
What is achalasia [2]
- Motlity disorder where LOS doesn’t relax so increased pressure. Hypertrophy of muscles at LOS
- Loss of peristalsis
The pathogenesis is thought to be due to decreased ganglionic cells in the myenteric plexus and degeneration in the vagal fibres of the oesophagus with loss of inhibitory denervation of the LOS.
How does achalasia present [6]
Dysphagia - solid and liquid from start over long periods of time
Weight loss
Regurg, Vomit
Aspiration, Choking
Chest pain
Systemically well
How do you Dx achalasia and what do they show [4]
Endoscopy 1st line to exclude cancer, would be normal
Barium swallow - dilated tight sphincter, birds beak deformity
CXR - wide mediastinum
Oesophageal manometry demonstrates aperistalsis in the distal two-thirds of the oesophagus and impaired relaxation of the LOS (pressure readings of >8 mmHg).
How do you Rx achalasia [5]
- Endoscopic pneumatic dilatation involves forceful disruption of the muscular fibres of the LOS using a balloon. It carries a significant risk of perforation (2–4%).
- Laparoscopic myotomy (Heller’s myotomy) involves longitudinal surgical incision of the muscles of the LOS.
- Peroral endoscopic myotomy (POEM) is an endoscopic method for performing myotomy of the LOS.
- Botulinum toxin injection into the LOS can provide temporary symptomatic benefit (lasting
~6 months), thus requiring repeat procedures. It is generally reserved for patients who are poor
surgical candidates. - Pharmacological therapy, such as nitrates or short-acting calcium channel blockers are the least
effective in treating achalasia. Their use is limited by side effects (such as headache and dizziness) with nitrates and tachyphylaxis (loss of response) with calcium channel blockers.
What are complications of achalasia [3]
SCC
Aspiration pneumonia
Lung disease
What does oesophageal spasm present like [4]
Intermittent chest pain and dysphagia

Odynophagia

How do you Dx spasm [2]

Oesophageal manometry classically demonstrates >20% simultaneous contractions of the LOS of
>30 mmHg amplitude.
Manometry - exaggerated contraction

Abdo pain and low Hb
Raised platelet + N+V, weight loss, dyspepsia, abdominal pain
Eosinophilic Oesophagitis
Aetiology
Endoscopic features & diagnosis
Management [2]
- Patients often have a history of atopy (e.g. eczema, allergic rhinitis or asthma). Food impaction is common
Aetiology - Chronic immune/antigen-mediated oesophageal disease characterised by symptoms related to oesophageal dysfunction and histologically eosinophilic predominant inflammation.
Endoscopic features - include linear furrowing, circular rings (trachealisation) and stricturing.
- Mid-oesophageal biopsies in patients with suspected EoE.
Management
* Initially acid suppression with proton pump inhibitors (in treatment naïve patients) followed by topical glucocorticoid therapy (e.g. swallowed fluticasone).
* Allergy testing is often advocated in EoE to determine foods that may present a risk for acute allergic reactions and identify EoE triggers.
Patients may present with oesophageal strictures which require therapeutic dilatation.
