    Abstract:
    BACKGROUND/AIMS: Bile leakage frequently causes major complications after hepatic resection. We investigated perioperative risk factors and management of postoperative bile leakage after hepatic resection without extrahepatic biliary resection and reconstruction. METHODS: We included 247 consecutive patients who underwent elective hepatic resection without bilioenteric anastomosis at our institution between 2002 and 2009. Perioperative risk factors, including patient and surgical variables, were evaluated using univariate and logistic regression analyses. RESULTS: Postoperative bile leakage occurred in 26 patients (10.5%). The surgical drain was retained in 6 patients (23%); 9 (35%) underwent drain salvage and 11 (42%) underwent percutaneous puncture under computed tomography or ultrasound guidance. Eight patients underwent endoscopic nasobiliary drainage (ENBD) for postoperative bile leakage, and bile leakage healed at a median interval of 19.5 days after ENBD. By univariate analysis, postoperative bile leakage was associated with central bisectionectomy, surgical time and intraoperative blood loss. Logistic regression analysis identified central bisectionectomy as an independent risk factor for postoperative bile leakage (p = 0.0003, odds ratio 16.724). CONCLUSION: Meticulous procedures are necessary during parenchymal hepatic resection, especially during central bisectionectomy. Drain management should be precise in the case of postoperative bile leakage. We believe ENBD may rapidly cure postoperative major bile leakage.
