Audit of an oesophageal unit.

We report an audit of 786 oesophageal procedures, including 53 oesophagectomies, performed during 1990 in a specialist oesophageal unit. Apart from assessing morbidity and mortality, audit allows a review of cost efficiency and justification for certain practices with regard to patient management. The data reported here may provide a framework against which individual surgeons may assess their own results and compare costs of procedures with a similar outcome.
