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 patients, 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.展开更多
