Predictors of mortality and morbidity in acute obstructive jaundice: implication of preventive measures.

Background/aims: The afferent events in acute obstructive jaundice (AOJ) are characterized by endotoxemia-induced decrease in systemic vascular resistance and bile salt mediated natriuresis and diuresis leading to diminished effective plasma volume.

Methodology: A prospective protocol aimed at preventing those alterations was carried out in 104 consecutive patients with AOJ. The preoperative risk factors that predict postoperative mortality and morbidity were reevaluated and correctable factors were identified.

Results: The average duration between the initiation of jaundice and surgery was 9.3 days. The perioperative mortality was 0%. The essentials of the treatment protocol were lactulose and cefazolin administration respectively for the prevention of portal endotoxemia and biliary sepsis and maintenance of body weight with adequately replaced fluid and electrolytes. Clinically relevant nutritional deficit was not observed in any of the patients during the perioperative period. The unique factor that predicted late mortality was the preoperative alanine transaminase value. Renal hemodynamics and hematologic parameters were completely correctable before the operation and patients with malignant or benign biliary strictures benefited and responded to the treatment similarly.

Conclusions: Measures taken to prevent the activation and progression of the afferent events in AOJ, have resulted in excellent clinical outcomes.
