Abstract

Background. Routine preoperative biliary drainage in cases of jaundice secondary to pancreatobiliary malignancy is associated with a significant risk of complications, failure and stent occlusion. It may be possible to avoid biliary drainage in those patients who are not deeply jaundiced. Aims. To measure presenting serum bilirubin and its rate of increase in patients with malignant obstructive jaundice. To predict the urgency with which surgery should be performed to avoid preoperative biliary drainage. Patients and methods. Prospective data collection for all pancreatic and periampullary malignancies over a period of 18 months was carried out. Serum bilirubin levels before successful drainage were recorded. Rates of increase in bilirubin and the number of days for bilirubin to reach different thresholds were calculated. Results. Of 111 patients, 66 (59%) had resectable disease on imaging investigations. Median serum bilirubin on presentation was 160 μmol/l. Median increase was 13.1 μmol/l/day or approximately 100 μmol/l/ week. The predicted number of days for bilirubin levels to reach a variety of thresholds varied significantly. For a patient presenting with a serum bilirubin of 160 μmol/l, the mean number of days for it to rise to 200 μmol/l, 300 μmol/l, 400 μmol/l and 500 μmol/l was 3, 13, 22 and 31 days, respectively. Conclusions. There is a variable window of opportunity in jaundiced patients with pancreatic and periampullary malignancy during which surgery may be performed to avoid biliary drainage procedures, depending on the threshold for operating on the jaundiced patient.
