[Risk assessment before elective visceral surgery interventions].
OBJECTIVE
Since 1988 all our patients undergoing elective general surgery entered a prospective study, with the aim of identifying risk factors, responsible for a fatal postoperative outcome.


METHODS
From 1988-1992 a total of 3250 patients (mean age 52.0 years [SD +/- 16.8]), 1750 male and 1500 female have been registered.


RESULTS
General complications occurred in 10.4% of patients and local complications have been registered in 10.8% of cases. 29 patients (0,89%) died within 30 days following the operative procedure. The operation per se, the ASA-classification, a history of respiratory disease and an operation for a malignant disease could be identified as risk factors for general postoperative complications.


CONCLUSIONS
The study design allows us to determine risk factors in elective general surgery. These risk factors can easy be used in clinical practice to evaluate the operative risk of a planned operative procedure.
