Acute oesophageal symptomsAuthors: A specialist registrar in gastroenterology, University Hospitals of Leicester, Leicester, UK; B consultant gastroenterologist, University Hospitals of Leicester, Leicester, UK and peptic stricture are the commonest abnormalities [2][3][4] (Table 1), followed by eosinophilic oesophagitis (EOE), which accounts for over 50% of food impactions in some published case series 2 (Fig 1). Less common causes are achalasia (Fig 2), reflux oesophagitis, extrinsic oesophageal compression and oesophageal cancer.Food bolus impactions are acute events immediately recognised by sufferers. Impactions at cricoid level may be Acute oesophageal symptoms include acute dysphagia or food bolus impaction (most commonly due to strictures, Schatzki ring and eosinophilic oesophagitis), acute chest pain with odynophagia due to oesophageal infections, motility disorders and acute oesophageal rupture (of which oesophageal intramural haematoma is a subtype). Acute full thickness oesophageal rupture carries a high mortality if not recognised early; the clinical features and conditions with which this may be confused are presented and discussed.
Acute oesophageal symptoms: definitions and causesThis review covers presentation and management of acute dysphagia, odynophagia and oesophageal chest pain.Dysphagia means 'difficulty in swallowing', distinguished from odynophagia ('pain on swallowing') by a sensation of bolus arrest/ delay, localised anywhere between cricoid and xiphisternum. The sensation of obstruction is associated with swallowing, differentiated from globus -a 'blockage' or 'lump' between cricoid and sternal notch independent of swallowing, typically persisting for hours 1 -and early satiety. The latter is often described as food 'lying' in the epigastrium or the retrosternal area but differing from dysphagia, which arises during swallowing, whereas the fullness of early satiety builds during a meal, eventually inhibiting intake. Food bolus obstruction is sudden-onset total dysphagia, discussed in more detail below.Oesophageal pain resembles other intra-thoracic/upper abdominal visceral pain (eg heart, aorta, gallbladder or lungs), not surprisingly since sensory pathways from these organs and chest wall enter the thoracic spinal cord at similar levels. Thus, oesophageal pain may occur in the chest, epigastrium, back, jaws or arm(s), and is more likely when dysphagia or odynophagia are present. Common causes of acute oesophageal symptoms are listed in Box 1.
Food bolus impactionFood bolus impaction is commonest in younger adults. In total, 88-97% of all patients with food bolus impaction have underlying oesophageal abnormalities.
