Purpose: The purpose of this retrospective study was to evaluate the utility of the new intraoperative bile leakage test as a preventive measure of postoperative bile leakage.
Method: 737 patients were retrospectively analyzed with respect to the management of intra- and post-operative bile leakage.
Results: Nine (8.3%) of 109 patients evaluated using conventional white light fluorescent imaging were recognized as having intra-operative bile leakage. However, performance of 5-aminolevulinic acid (5-ALA)-mediated PDD detected bile leakage intraoperatively not only in these 9 patients, but also in an additional 6 patients, such that 'red fluorescence' at the cut surface of the liver, was visualized in a total of 15 patients. The postoperative courses of most patients were uneventful, and postoperative bile leakages occurred in only one (0.9%) patient.
Conclusion: 5-ALA fluorescence imaging may be needed to prevent postoperative bile leakage in patients at high risk for this surgical complication after hepatic resection.
