Objective:
To estimate the operative mortality in patients with malignant obstructive jaundice.
Methods:
Twelve risk factors were analyzed using multivariate discriminant analysis in 90 patients who had been operated on.
Results:
Operative mortality was significantly related to the following factors: age, duration of jaundice, packed RBC volume, white blood cell count and concentration of blood urine nitrogen; it was not significantly related to diseases and types of operation. The following formula was obtained: packed RBC volume x 0.09954-age x 0.04018- blood urine nitrogen x 0.23693-duration of jaundice x 2.07388-WBC count x 0.21118+ 5.26593. With this formula, an operative mortality of 77.8% was predicted.
Conclusion:
With a positive value from the formula, the patient should be operated on; otherwise non-operative treatment is advocated.
