ABSTRACT: Prolonged intubation results in ventilator-associated pneumonia (VAP), which contributes to significant mortality among patients on the waiting list. The aim of this study was to determine the risk factors for and clinical outcomes of VAP among patients into the intensive care unit (ICU).
We enrolled 50 consecutive critically ill patients with end-stage liver disease admitted to the ICU from January 2005 through December 2010. All patients were intubated for more than 4 days; no definite infection was found initially. We evaluated potential risks factors for VAP and clinical outcomes.
Smoking, underlying liver disease, and lobar focal consolidations were significant factors for patients with versus without VAP. Fourteen-day mortality rates were 61.5% for VAP versus 40.5% for patients without VAP. Twenty-eight-day mortality rates for both groups were 92.3% and 86.5%, respectively. Multivariate analysis failed to identify independent predictors of early 14-day mortality.
Underlying liver disease and lobar focal consolidations were risks factors for VAP in patients with prolonged intubation. Patients with prolonged intubation have a dismal prognosis even without VAP. The clinical outcomes of patients with versus without VAP were similar. However, early liver transplantation (<14 days of intubation) improves the chance to rescue patients before development of VAP.

ABSTRACT: Overweight/obesity is currently a common health issue that may cause many diseases, even malignancies. The influence of steatosis on long-term results of surgical treatment for hepatocellular carcinoma (HCC) is not well known. The aim of this study is to analyze the results of hepatectomy for HCC patients with steatosis.
The study included 1048 patients who underwent hepatectomy for HCC from 1999 to 2005. The patients were divided into two groups; group A patients without steatosis (n = 693) and group B patients with steatosis (n = 355). The clinicopathological data and long-term survival were analyzed.
Mean tumor size in group B patients was smaller than that in group A patients (4.61 ± 3.40 vs. 5.91 ± 4.36 cm, p < 0.01). Group B patients showed lower tumor differentiation grade, lower vascular invasion rate and better 5-year overall survival compared to group A patients (61.2% vs. 50.1%, p = 0.001). By multivariate analysis, steatosis was found to be associated with well-differentiated, small-sized, and less α-fetoprotein productive tumors. When focusing on the tumors >5 cm in diameter, group B patients had better survival rate than group A patients (p = 0.041). Vascular invasion and steatosis were independent prognostic factors for the overall survival.
HCC in steatotic liver was less aggressive than that in non-steatotic liver. HCC patients with steatosis have better surgical outcomes than those without steatosis. Vascular invasion and steatosis were independent prognostic factors for the overall survival if tumors were >5 cm in diameter.

ABSTRACT: The aim was to compare short-term results of right hepatectomy using the anterior approach (AA) and liver hanging manoeuvre with the conventional approach (CA) for large hepatocellular carcinoma (HCC).
This was a retrospective review of 71 consecutive patients with HCC at least 5 cm in diameter who underwent curative right hepatectomy using either the AA with the liver hanging manoeuvre (33) or the CA (38) between January 2004 and December 2008. Clinical data, operative results and survival outcomes were analysed.
The groups had similar clinical, laboratory and pathological parameters. The AA group had larger tumours than the CA group (P = 0.039), but comparable grade and stage distribution. The operative results were similar except for an increased blood transfusion requirement with the conventional procedure (P = 0.001). The AA group had a lower recurrence rate (P = 0.003) and better disease-free survival (DFS) (P = 0.001) than the CA group, but overall survival rates were not significantly different (P = 0.091). Presence of tumour encapsulation, absence of tumour microvascular invasion and AA were predictive of DFS, whereas tumour stage was the only independent predictor of overall survival.
The AA right hepatectomy with liver hanging manoeuvre for large HCC is associated with reduced blood transfusion requirement and lower recurrence rates in the short term.

ABSTRACT: Liver transplantation is the treatment of choice for end-stage liver disease. However, the shortage of donors is still the major problem in most Asian countries. Using extended donor criteria may maximize the deceased donor pool, but some high-risk donors may show adverse recipient outcomes due to preexisting infection.
This study included deceased donor liver transplant patients from June 2002 through June 2007. We retrospectively reviewed the clinical manifestations of donors and recipients. The donors showed no definite infection at the time the organs were matched to the recipients. Routine sputum, urine, blood, and bile cultures were obtained from the donor during the perioperative period. According to the final reports of the cultures, the recipients divided into two groups: donor infection (DI) and no donor infection (NDI).
This study included 59 donor and 72 recipients, including 34 who received a graft from a donor with a positive culture (47.2%) finally, defined as the DI groups, and 38 recipients (52.8%) as the NDI group. Most of them had positive sputum cultures, followed by urine cultures. Staphylococcus aureus was the most common pathogen. Using a stepwise logistical regression model to analyze the significant donor characteristics, donor admission to the intensive care unit (ICU) for 7 days or longer (P < or = .0001), previous cardiopulmonary cerebral resuscitation (CPCR) (P = .036), and inotropic agents (P = .022) were the only three independent factors to predict donor infection. To compare the outcomes between DI and NDI groups, the days of recipient ICU or hospital admission, the 1-week or 1-month mortality rate, and the overall survival showed no significant difference between both groups. However, the hospital mortality rate was mildly higher in the DI group (P = .050).
Donors with prolonged ICU admissions, rescue by CPCR, and use of inotropic agents carried an high risk of potential infections. Our data did not show a significant increase in adverse outcomes if the recipient received a graft from a potentially infected donor. However, there may be an increased risk of hospital mortality. We should be careful in using these potentially infected donors in selective recipients.

ABSTRACT: Hepatocellular carcinoma (HCC) is a common disease in Taiwan. Ruptured HCC is an uncommon and potentially fatal complication of the condition. Information on the impact of ruptured HCC on hepatic resection is, however, limited.
The clinical features of 60 patients with ruptured HCC who underwent hepatic resection from 1986 to 1998 were reviewed. Clinical features and factors influencing the outcome of 475 patients with non-ruptured HCC were used for comparison.
Of 535 surgically resected HCCs, 60 (11.2 per cent) were ruptured. Univariate analysis showed that sudden onset of abdominal pain, physical signs of haemodynamic unstability, reduced haemoglobin level and a raised aspartate aminotransferase level were more frequently found in patients with ruptured HCC than in those with non-ruptured tumours. Multivariate stepwise logistic regression analysis revealed sudden-onset abdominal pain to be the only independently significant factor in patients in the ruptured HCC group. The 1-, 3- and 5-year survival rates of patients with non-ruptured HCC were 72.1, 47.3 and 33.9 per cent, and those of patients with ruptured HCC were 54.2, 35.0 and 21.2 per cent respectively. Similar overall survival rates were found in patients with ruptured and non-ruptured HCC, although patients in the non-ruptured HCC group had a significantly better disease-free survival rate (P = 0.023).
The presence of sudden-onset abdominal pain is the only independent indicator of ruptured HCC. Hepatic resection, when feasible, is the treatment of choice and can result in an overall survival rate comparable to that of patients with non-ruptured HCC.
