Examination
Obviously a full examination is necessary but the following points are particularly important:
General inspection
General physic eg cachexia and mobility in outpatient room
Specific points
Cervical lymph nodes
Presence of goiter
Thoracotomy and abdominal scars. It is amazing how many patients have forgotten about the perforated ulcer that required a gastric resection, or the bleeding duodenal ulcer that has had the gastroduodenal artery tied off - which your stomach tube requires to stay alive.
Factors that affect operative morbidity and mortality
Respiratory status - How clear is the chest
Cardiovascular status - Heart murmurs, Carotid bruits, Peripheral vascular disease, and Oedema
