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: Surgical site infections (SSIs), particularly organ/space SSIs, remain a common cause of major morbidity after hepatectomy for hepatocellular carcinoma (HCC). METHODS: Risk factors for SSIs were analyzed in 359 patients who underwent hepatectomy for HCC between 2001 and 2010. The causative bacteria, management, outcome, and characteristics of organ/space SSIs were investigated. RESULTS: Anatomic hepatectomy was performed for 296 patients (82.5%), and repeat hepatectomy was carried out for 59 patients (16.4%). SSIs developed in 52 patients (14.5%; incisional, 24 cases; organ/space, 31 cases [3 patients showed both incisional and organ/space SSIs]). No in-hospital mortality related to incisional or organ/space SSIs was encountered. Independent risk factors for SSIs were repeat hepatectomy and operative time ≥280 min. Independent risk factors for organ/space SSIs were repeat hepatectomy and bile leakage. Methicillin-resistant Staphylococcus aureus was detected more frequently in organ/space SSIs after repeat hepatectomy than after initial hepatectomy. CONCLUSIONS: Repeat hepatectomy and bile leakage represent independent risk factors for organ/space SSIs after hepatectomy for HCC. Establishing treatment strategies is important for preventing postoperative bile leakage and reducing the high rate of organ/space SSIs after repeat hepatectomy.

    ABSTRACT: Biliary leakage after liver resection continues to be reported. Management of bile leakage has changed in recent years, with nowadays non-surgical procedures as the preferred treatment. Biliary leakage and management were assessed in 381 patients who underwent liver resection between January 2005 and April 2011. The overall rate of biliary leakage after liver resection was 5.0%, with a higher incidence in patients who had undergone concomitant hepaticojejunostomy (HJ; 13.6 vs. 3.2%). Hospital stay (p = 0.047), major resections (p = 0.018), operation time (p = 0.011), and relaparotomy (p = 0.002) were risk factors for postoperative bile leakage. Multivariate analysis identified relaparotomy as an independent factor (OR 4.216, p = 0.034). Bile leakage in patients without HJ (n = 10) was managed in 6 patients by percutaneous transhepatic biliary drainage (PTD), and in 3 patients by endoscopic drainage. One patient was treated surgically. All patients with an HJ and postoperative bile leakage (n = 9) underwent PTD. The incidence of posthepatectomy biliary leakage has decreased over time, while PTD and endoscopic stenting are effective treatment modalities. PTD is the treatment of choice in bile leakage after resection combined with HJ.

    ABSTRACT: The effectiveness of subcuticular absorbable suture with subcutaneous drainage to decrease the risk of postoperative incisional surgical site infection (SSI) in hepatocellular carcinoma (HCC) patients was evaluated. A total of 149 patients with HCC who underwent hepatectomy (Hx) were retrospectively investigated. Patients were divided into two groups: the patients with subcuticular suture combined with subcutaneous drainage (the drainage group; 61 patients) and the patients with nylon suture without subcutaneous drainage (the nylon group; 88 patients). After the operations, the complication rate of postoperative incisional SSI was analyzed and compared between the two groups. In the drainage group the rate of incisional SSI was significantly lower compared to the nylon group: 14-3 % (p = 0.033), respectively. Patients with incisional SSI needed significantly longer postoperative hospital care than the patients without incisional SSI: 28 versus 15 days (p < 0.005). Multivariate analysis revealed that subcuticular absorbable suture with subcutaneous drainage significantly reduced the occurrence of incisional SSI (odds ratio; 0.15; p = 0.034). We have demonstrated that the subcuticular suture with subcutaneous drainage is effective in preventing incisional SSI in patients undergoing Hx for HCC.
