Synopsis
Differentiate major oesophageal motor disorders from structural, cardiac and functional mimics, then use physiology-led, proportionate specialist treatment.
- Oesophageal chest pain and dysphagia have structural, inflammatory, reflux, cardiac and functional causes; motility testing follows appropriate exclusion rather than replacing it.
- High-resolution manometry classifies motor patterns using pressure topography, but a technically named pattern is clinically meaningful only when symptoms and supportive evidence align.
- Distal oesophageal spasm features premature contractions with preserved oesophagogastric junction relaxation, whereas type III achalasia combines premature activity with impaired relaxation.
- Hypercontractile oesophagus has excessive contractile vigour during otherwise propagated swallows and should not be diagnosed from one forceful contraction.
- Oesophagogastric junction outflow obstruction is a manometric observation, not automatically a disease; mechanical causes, artefact and opioid effects must be considered.
- Absent contractility and ineffective oesophageal motility can accompany systemic sclerosis, reflux or medicines and often require supportive reflux and swallowing care.
- Endoscopy with suitable biopsies excludes cancer, stricture and eosinophilic oesophagitis before dysphagia is attributed to spasm.
- Timed barium swallow, solid test meal, rapid drink challenge or functional lumen imaging may provide supportive evidence when standard swallows are equivocal.
- PPIs help coexisting proven reflux but do not directly normalise primary spastic contractions; repeated empirical escalation can distract from the actual phenotype.
- Smooth-muscle relaxants, neuromodulation and myotomy have variable evidence and adverse effects, so treatment belongs in a specialist, shared-decision pathway.
Key red flags
Squeezing retrosternal pain may occur with swallowing or at rest, but cardiac and aortic emergencies require appropriate exclusion before oesophageal spasm is considered.
Progressively worsening solid-food dysphagia, weight loss, anaemia, bleeding or persistent vomiting points away from a benign motor label and toward urgent endoscopy or cancer assessment.
Sudden inability to swallow solids, fluids or saliva requires urgent endoscopic assessment and investigation for a ring, stricture, EoE or major motor disorder.
Investigation priorities
Exclude myocardial ischaemia or another cardiovascular emergency during acute chest pain.
Management branches
A patient reports unexplained dysphagia or recurrent oesophageal-type chest pain.
- Triage acute coronary, aortic, obstructive and perforation features first, and use urgent pathways rather than elective physiology when present.
- Review symptom consistency, reflux, impaction, weight, systemic disease and medicines, especially prescribed or non-prescribed opioids.
- Undertake endoscopy with appropriate oesophageal biopsies before attributing dysphagia to a motor diagnosis.
- Perform high-resolution manometry through an accredited service and add timed barium, provocative swallows or reflux monitoring when needed to connect the pattern to symptoms.
Key medicines
Proton pump inhibitor for documented refluxUse a licensed full-dose PPI regimen from the current BNF for an adequate initial course, then step down or continue according to objective reflux, mucosal injury and symptom benefit.Reassess adherence and indication before escalation. Dysphagia, weight loss or non-response requires structural and physiological review, not repeated empirical dose increases.
Smooth-muscle relaxant such as a nitrate or calcium-channel blockerIf a physiology specialist recommends an off-label trial, use the exact current BNF and local protocol for the chosen product, beginning cautiously and reviewing benefit promptly; no regimen applies universally across spastic phenotypes.Evidence is limited and headache, flushing, hypotension, syncope and oedema can outweigh benefit. Check cardiovascular disease, interacting antihypertensives and absolute nitrate interaction with phosphodiesterase-5 inhibitors; give falls and driving advice.
