The Oesophagus -regurgitation & dysphagia Flashcards
Regurgitation
Passive evacuation of food and/or fluid from oesophagus
Results from local mechanical events within oesophagus
Dysphagia
Difficulty swallowing
Differentiating between oropharyngeal and osophageal dysphagia
Oropharyngeal (oral, pharyngeal, cricopharyngeal)
Try & swallow repeatedly but gag, retch, struggle to drink & may eject food from mouth (immediately after eating)
Oesophageal
Usually only 1 swallowing attempt, may or may not be able to drink, may bring up food at any time after eating
Regurgitation versus vomiting
Nasusea is before vomitting not regurgitation
Retching before vomitting not regurgitation
Food partially digested in vomiting not regurgitating
Clinical signs of Aspiration pneumonia
Soft cough, dyspnoea, tachypnoea, pyrexia, lung crackles, +/- nasal discharge
Predilection site for aspiration pneumonia
Right middle lung lobe
Aspiration pneumonia Treatment
Oxygen therapy if needed
Fluid therapy if needed
Broad spectrum antibiotics
Nebulisation
Coupage
Oesophageal diseases can be split into 2 catergories which are…?
Obstructive E.g Foreign body, Neoplasia, Vascular ring anomaly
Functional E.g. Megaesophagus, Gastroesophageal reflux
Signs of oesophageal disease
Regurgitation
Dysphagia
+/- Odynophagia- Painful swallowing
+/- Ptyalism- Too much saliva
+/- Ravenous or reduced appetite
+/- Weight loss
+/- Respiratory signs due to secondary aspiration pneumonia
Type of contrast used in visualsing oesophagus
Barium sulphate
Vascular ring anomaly
Congenital vascular anomaly
Persistant right aortic arch (most common)
Causes significant narrowing & obstruction of oesophagus
Clinical signs of vascular ring anomaly
Start regurgitating when weaned
Often have weight loss & stunting
Breeds predisposed to vascular ring anomaly
GSDs & Irish Setters
Treatment to treat vascular ring anomaly
Surgery to transect ligamentum arteriosum
Foreign body treatment
Medical emergency
Stabilise patient
General anaesthesia
Endoscopic removal – 1st choice
