Evaluation of the White Test for the Intraoperative Detection of Bile Leakage

الملخص EN

We assess whether the White test is better than the conventional bile leakage test for the intraoperative detection of bile leakage in hepatectomized patients.

This study included 30 patients who received elective liver resection.

Both the conventional bile leakage test (injecting an isotonic sodium chloride solution through the cystic duct) and the White test (injecting a fat emulsion solution through the cystic duct) were carried out in the same patients.

The detection of bile leakage was compared between the conventional method and the White test.

A bile leak was demonstrated in 8 patients (26.7%) by the conventional method and in 19 patients (63.3%) by the White test.

In addition, the White test detected a significantly higher number of bile leakage sites compared with the conventional method (Wilcoxon signed-rank test; P<0.001).

The White test is better than the conventional test for the intraoperative detection of bile leakage.

Based on our study, we recommend that surgeons investigating bile leakage sites during liver resections should use the White test instead of the conventional bile leakage test.
