    ABSTRACT: Subcostal incision is the most widely used approach in open surgery for patients with hepatocellular carcinoma (HCC). Body shape is recognised to be a factor influencing the difficulty of surgery; however, the exact impact of the increased difficulty on the patients’ operation as well as the outcome has not been analysed. In this study, we retrospectively studied the possible influence of patients’ body shape, tumour burden and varied surgical methods on the operation procedure and postoperative complications. From January 2009 to December 2013, 651 patients with HCC were included in the study. We studied the patients’ sex, age, body mass index, upper abdominal body shape described by the depth-to-width ratio for the trunk at the celiac axis on CT/MRI, Child-Pugh classification, tumour burden and a different liver dissection method before the surgery and used a regression model for analysis. Prolonged operation time is associated with advanced tumour stage, large CA ratio, previous abdominal surgery, selective hepatic vascular occlusion and dissecting with Cavitron ultrasonic surgical aspirator rather than clamp crushing. Surgical blood loss is associated with operation time, liver function and a different liver dissection method. The incidence of severe postoperative complication was 17.5 % (114/651) and was associated with larger CA ratio, Child-Pugh stage B liver function and greater blood loss. Large upper abdominal shape is a risk factor of both prolonged operation time and severe postoperative complication. CA ratio combined with liver function and surgical blood loss has an acceptable power to predict severe postoperative complications.

    ABSTRACT: Many advanced hepatocellular carcinoma (HCC) cases can be successfully downstaged into the Milan criteria; however, immediate radical therapy cannot be applied to all such patients for various reasons. Of the patients who are not eligible for immediate radical therapy, some accept repeated downstaging therapies and some undergo persistent observation. The aim of the present study was to compare long-term survival between these two groups of patients. Between August 2003 and October 2008, 156 HCC patients successfully received downstaging therapy resulting in compliance with the Milan criteria. Of those, 98 cases accepted radical therapies, including liver transplantation (LT), resection, or radiofrequency ablation (RFA) (group 1), and 58 cases underwent repeated transcatheter arterial chemoembolization (TACE) or persistent observation (group 2). The baseline characteristics, demographic data, downstaging protocol, and information on long-term outcomes were collected and compared. No significant differences were observed in the patient demographic data, downstaging protocols, or tumor characteristics between the two groups. The 1-, 3-, and 5-year overall survival rates were 92.9, 82.7, and 78.6 %, respectively, in group 1, whereas these rates were 82.8, 65.5, and 48.3 %, respectively, in group 2 (P = 0.046). Among the 58 patients in group 2, the 1-, 3-, and 5-year overall survival rates were 92.3, 65.4, and 46.2 %, respectively, in the repeated TACE group, and 81.3, 65.6, and 50 %, respectively, in the persistent observation group (P = 0.783). Immediate radical therapy should be the first choice for advanced HCC patients who undergo successful TACE, and repeated TACE is unnecessary.

    ABSTRACT: Adult-to-adult living donor liver transplantation (A-A LDLT) is an effective therapeutic modality to treat patients with end-stage liver disease. The aims of this study were to identify recipient characteristics of A-A LDLT seeking to determine variables that affected patient survival. We retrospectively examined a cohort of 154 consecutive A-A LDLT recipients with end-stage liver disease in our center over 4 years. All donors volunteered to give their partial livers with written consent. There were no organs from prisoners and no prisoner subjects. The overall survivals at 1, 2, 3, 6, 12, 24, 36, and 48 months were 93.5%, 90.9%, 88.9%, 86.3%, 80%, 65.6%, 63.8%, and 63.8%, respectively. About 31 pre- and intraoperative factors were analyzed to identify correlations with posttransplant survival using the Cox proportional-hazards regression model. Recipient age, serum creatinine concentration, intraoperative blood loss, and graft-to-recipient weight ratio were significant predictors of survival after transplantation. The prognostic index model, which was calculated by combining these four prognostic values with their regression coefficients, showed a c-statistic of 0.706 (95% confidence interval [CI] = 0.621-0.792) compared with the Model for End-stage Liver Disease value of 0.546 (95% CI = 0.350-0.558). There was a significant difference between the predictions achieved with the two models (P = .012). In conclusion, selecting younger recipients, better pretransplant renal condition, reduced intraoperative blood loss, and graft-to-recipient size match appeared to be advantageous to achieve better survivals among patients undergoing A-A LDLT.

    ABSTRACT: Evaluation of graft hepatic steatosis is important for the safety of the donor and the recipient in living donor liver transplantation. It is necessary to establish a noninvasive evaluation method to avoid performing a liver biopsy for donor safety. The aim of this study was to identify independent factors that correlated with hepatic steatosis to create a noninvasive method to evaluate hepatic steatosis. We retrospectively collected data from 105 living donors. No prisoners were used to obtain the grafts, all of which underwent postoperative histological evaluation for hepatic steatosis. Preoperative clinical and biochemical variables were examined with univariate analyses, and filtered variables further examined with ordinal regression analysis. Eighty (76.2%) donors showed no hepatic steatosis, 15 (14.3%), mild steatosis, and 10 (9.5%), moderate steatosis. In ordinal stepwise regression analysis, body mass index (BMI; P = .000) was the only independent factor that correlated with the grade of hepatic steatosis. Preoperative biochemical parameters were not significantly correlated with hepatic steatosis. A regression model based on BMI was created to evaluate hepatic steatosis grade. Furthermore, individuals with a BMI > 27.5 were most likely to show moderate steatosis, and those with BMI < 23 likely to display no or mild steatosis. BMI can help to identify the grade of hepatic steatosis among living donors. BMI is also useful to select living donors for a preoperative liver biopsy before liver transplantation.

    ABSTRACT: The aim of this study was to explore the indications for liver transplantation among patients with hepatolithiasis. Data from 1,431 consecutive patients who underwent surgical treatment from January 2000 to December 2006 were retrospectively collected for analysis. Surgical procedures included T-tube insertion combined with intraoperative cholangioscopic removal of intrahepatic stones, hepatectomy, cholangiojejunostomy, and liver transplantation. Nine hundred sixty-one patients who had a stone located in the left or right intrahepatic duct underwent hepatectomy or T-tube insertion combined with intraoperative cholangioscopic removal of intrahepatic stones. The rate of residual stones was 7.5%. Four hundred seventy patients who had a stone located in the bilateral intrahepatic ducts underwent surgical procedures other than liver transplantation; the rate of residual stones was 21.7%. Only 15 patients with hepatolithiasis underwent liver transplantation; they all survived. According to the degree of biliary cirrhosis, recipients were divided into 2 groups: a group with biliary decompensated cirrhosis (n = 7), or group with compensated cirrhosis or no cirrhosis (n = 8). There were significant differences in operative times, transfusion volumes, and blood losses between the 2 groups (P < .05). In the first group, 6 of 7 patients experienced surgical complications, and in the second, 8 recipients recovered smoothly with no complications. Health status, disability, and psychological wellness of all recipients (n = 15) were significantly improved at 1 year after transplantation compared with pretransplantation (P < .05). Liver transplantation is a possible method to address hepatolithiasis and secondary decompensated biliary cirrhosis or difficult to remove, diffusely distributed intrahepatic duct stones unavailable by hepatectomy, cholangiojejunostomy, and choledochoscopy.
