Abstract 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×0.09954-age×0.04018- blood urine nitrogen×0.23693-duration of jaundice× 2.07388-WBC count×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.
