ABSTRACT The purpose of this study was to identify risk factors for major morbidity after hepatectomies for hepatocellular carcinoma (HCC).
Univariate and multivariate analyses of risk factors for major morbidity were performed in 293 patients who underwent hepatectomy for HCC between 2001 and 2008.
Two hundred and forty-three patients (82.9%) underwent an anatomic hepatectomy, and a repeat hepatectomy was performed in 50 patients (17.1%). The prevalences of bile leakage and intraabdominal abscess were 12.9% and 9.2%, respectively. The risk factor for bile leakage was an operative time >or= 300 min and the risk factor for intraabdominal abscess was a repeat hepatectomy (odds ratios = 4.9 and 5.3, respectively). The main cause of bile leakage that made endoscopic therapy or percutaneous transhepatic biliary drainage necessary was a latent stricture of the biliary anatomy that had existed preoperatively, caused by previous treatments for HCC. Methicillin-resistant Staphylococcus aureus was the main causative bacteria of intraabdominal abscess after repeat hepatectomies.
Our recent series revealed that prolonged operative time and repeat hepatectomy were independent risk factors for bile leakage and intraabdominal abscess, respectively, after hepatectomies for HCC. Preoperative assessment of the biliary anatomy should be considered for patients who have had previous multiple treatments for HCC, including hepatectomy, to reduce bile leakage that makes invasive treatment necessary.

    ABSTRACT: BACKGROUND: Bile leakage, and organ and/or space surgical-site infection (SSI) are common causes of major morbidity after partial hepatectomy for hepatocellular carcinoma (HCC). The purpose of this study was to analyse risk factors for major morbidity and to explore strategies for reducing it after partial hepatectomy for HCC. METHODS: Risk factors for bile leakage and organ/space SSI were analysed in patients who underwent partial hepatectomy for HCC between 2001 and 2010. The causes, management and outcomes of intractable bile leakage requiring endoscopic therapy or percutaneous transhepatic biliary drainage were analysed. In addition, causative bacteria, outcomes and characteristics of organ/space SSI were investigated. Risk factors were identified using multivariable analysis. RESULTS: Some 359 patients were included in the analysis. The prevalence of bile leakage and organ/space SSI was 12·8 and 8·6 per cent respectively. Repeat hepatectomy and an operating time of at least 300 min were identified as independent risk factors for bile leakage. The main causes of intractable bile leakage were latent strictures of the biliary system caused by previous treatments for HCC and intraoperative injury of the hepatic duct during repeat hepatectomy. Independent risk factors for organ/space SSI were repeat hepatectomy and bile leakage. Methicillin-resistant Staphylococcus aureus was detected more frequently in organ/space SSI after repeat hepatectomy than after initial partial hepatectomy. CONCLUSION: Repeat hepatectomy and prolonged surgery were identified as risk factors for bile leakage after liver resection for HCC. Bile leakage and repeat hepatectomy increased the risk of organ/space SSI. Copyright © 2012 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd.

    ABSTRACT: Hepatic resection had an impressive growth over time. It has been widely performed for the treatment of various liver diseases, such as malignant tumors, benign tumors, calculi in the intrahepatic ducts, hydatid disease, and abscesses. Management of hepatic resection is challenging. Despite technical advances and high experience of liver resection of specialized centers, it is still burdened by relatively high rates of postoperative morbidity and mortality. Especially, complex resections are being increasingly performed in high risk and older patient population. Operation on the liver is especially challenging because of its unique anatomic architecture and because of its vital functions. Common post-hepatectomy complications include venous catheter-related infection, pleural effusion, incisional infection, pulmonary atelectasis or infection, ascites, subphrenic infection, urinary tract infection, intraperitoneal hemorrhage, gastrointestinal tract bleeding, biliary tract hemorrhage, coagulation disorders, bile leakage, and liver failure. These problems are closely related to surgical manipulations, anesthesia, preoperative evaluation and preparation, and postoperative observation and management. The safety profile of hepatectomy probably can be improved if the surgeons and medical staff involved have comprehensive knowledge of the expected complications and expertise in their management. This review article focuses on the major postoperative issues after hepatic resection and presents the current management.
