BACKGROUND: The primary focus of the study was to ana-lyze the risk factors for bile leakage after hepatectomy for be-nign or malignant tumors. METHODS: A total of 411 patients who had undergone hepa-tectomy between December 2006 and December 2011 were ret-rospectively analyzed. The severity of bile leakage was graded according to the ISGLS classification. Twenty-eight pre- and postoperative parameters were analyzed. RESULTS: The overall bile leakage incidence was 10.2% (42/411). The severity of the leakage was classified according to the IS-GLS classification. Bile leakage was detected early in case of abdominal drainage (11.4% vs 1.9%, P=0.034). It prolonged the time of hospitalization (16 vs 9 days, P=0.001). In all pa-tients, wedge resection was associated with a higher incidence of bile leakage in contrast to anatomical resections (25.6%vs 4.1%, P<0.0001) regardless of the underlying liver disease. Furthermore, total vascular exclusion increased risk of bile leakage (P=0.008). CONCLUSIONS: Bile leakage as a major issue after hepatic resection is related to the postoperative morbidity and the hospitalization time. It is associated with non-anatomical re-section and a total vascular exclusion.
