Abstract
For a few years, many descriptions and studies have been published regarding precancerous nodular liver lesions. As a result, several terms and classifications have been proposed leading to poor reproducibility. In 1995, an International Working Party defined nodular lesions called low grade and high grade dysplastic nodules. A good correlation between clinical, radiological and pathological lesions was then obtained. This article summarizes the histopronostic features of the nodules observed in cirrhotic liver, and attempts to specify the diagnostic criteria to distinguish dysplastic from regenerative macronodules and hepatocellular carcinomas.

Abstract
OBJECTIVE To describe three unusual cases of sclerosing cholangitis after severe extrahepatic/extrabiliary bacterial infections. DESIGN Case report, clinical. SETTING Tertiary care intensive care unit (ICU). PATIENTS Three patients admitted to the ICU with infections from Gram-positive bacteria followed by sclerosing cholangitis and secondary biliary cirrhosis. MAIN RESULTS Three unusual cases of persisting cholestasis that occurred after bacterial infections originating from extrahepatic/extrabiliary foci are described. Endoscopic retrograde cholangiopancreatography and magnetic resonance cholangiopancreatography revealed multiple strictures of the intrahepatic bile ducts as a sign of sclerosing cholangitis. All patients progressed to biliary cirrhosis within months after the onset of cholestasis. CONCLUSION Infection-associated cholestasis is usually a functional disorder and subsides after effective treatment of the underlying inflammatory focus. In rare cases, however, extrahepatic/extrabiliary infections may lead to sclerosing cholangitis and secondary biliary cirrhosis via unknown mechanisms.

Abstract
Until recently, cirrhosis has been considered to be an absolute or relative contraindication of laparoscopic cholecystectomy. An evaluation of benefits and risks of laparoscopic cholecystectomy in the treatment of gall bladder lithiasis in cirrhotic patients is presented. Thirty-three consecutive laparoscopic cholecystectomies in patients with cirrhosis were performed between March 1990 and March 1997. During the same period, no open cholecystectomy was performed in patients with cirrhosis. There was no morbidity or mortality; the conversion rate was 6% (2/33). No patient received blood transfusion, and the mean hospital stay was 2.8 days. These results favorably compare with the results of open cholecystectomy. Specific advantages of laparoscopic cholecystectomy in patients with cirrhosis include the absence of wound infection and a lower rate of postoperative hepatic failure. Finally, laparoscopic surgery reduces the risk of viral contamination (the hepatitis B virus, the hepatitis C virus, or the human immunodeficiency virus) of the surgical staff.

Abstract
The aim was to assess the validity of a digitally computed fibrosis ratio as a measure of fibrosis stage in liver biopsy specimens. We scored 230 liver biopsy specimens from patients with chronic hepatitis C for fibrosis using modified Knodell criteria; fibrosis ratios were computed from digital images that encompassed the complete trichrome-stained section of each case. Although an overall correlation between fibrosis ratio and ordinal score was present, subset analysis showed that this correlation existed only among biopsy specimens with high scores (3-6, early bridging fibrosis to established cirrhosis). There was no correlation or difference between category means found among biopsy specimens with low scores (0-3, normal to early bridging fibrosis). Furthermore, concordance by both estimates in direction of fibrosis change among serial liver biopsy specimens was found in only 11 (30%) of 37 pairs compared. The findings suggest that a qualitative assessment of the computerized fibrosis pattern is necessary for the interpretation of computerized fibrosis ratio measurements, particularly in patients with early stage fibrosis.

Abstract
Patients with cirrhosis have reduced life expectancy. Surgery is often associated with clinical decompensation in this group of patients. The purpose of this paper is to study the surgical risk in cirrhotic patients undergoing nonderivative operations. Unfortunately, most of the studies in the literature about this problem are retrospective reviews with limitations. The conditions increasing surgical risk in cirrhotic patients are analysed. These include changes in the pharmacokinetics and pharmacodynamics of various drugs, altered hemostasis, poor resistance to infections, water retention, suture line insufficiency, chronic renal failure and congestive heart failure. Assessment of the disease stage in cirrhosis is very important, because the severity of hepatic abnormalities influences the prognosis. The Child-Pugh classification has been used extensively to risk-stratify patients with cirrhosis. However, the disregard for cardiorespiratory, renal, electrolyte balance and acid-base status limits its predictive accuracy. Recently a new scoring system, the Acute Physiology and Chronic Health Evaluation (APACHE III), has been introduced and seems to be superior to Child-Pugh for prognosticating short term survival of cirrhotic patients. In conclusion, surgery can be done safely only in cirrhotic patients with a good hepatic function. On the contrary, in patients with advanced cirrhosis, surgery causes a very high mortality. Finally, the patients with moderate hepatic failure can be operated only after a careful study of the disease and an adequate correction of the reversible risk factors.

Abstract
In the liver, transforming growth factor (TGF) -beta(1)is primarily responsible for activation of fat-storing cells, which are the main source of extracellular matrix proteins. Their deposition play a key role in the development of liver cirrhosis. The aim of this study was to evaluate plasma TGF-beta(1)in patients with different stages of liver cirrhosis and its possible use as an indicator of liver function impairment. TGF-beta(1)was measured in the plasma of 40 patients with liver cirrhosis. To estimate possible effect of liver insufficiency on plasma TGF-beta(1), patients were divided into three groups: A, B and C, univocal with Child-Pugh classes. Normal values were collected from 13 healthy volunteers. Liver cirrhosis resulted in a significant increase of plasma concentration of TGF-beta(1)(39.3+/-3.8 ng/ml), which doubled normal values (18.3+/-1.6 ng/ml). The highest concentrations were observed in alcoholic patients (44.4+/-4.7 ng/ml). TGF-beta(1)level increased depending on the degree of liver insufficiency, demonstrated by a significant positive correlation with Child-Pugh score (r=0.591). Values in group A were similar to normal, but were significantly elevated in groups B and C. These findings suggest possible use of plasma TGF-beta(1)measurement as an indicator of liver function impairment and possible marker of hepatic fibrosis progression in cirrhotic patients.

Abstract
BACKGROUND The etiologic heterogeneity of fibrotic liver disease has resulted in the formulation of diverse, often disease-specific, classification systems for biopsy assessment, based on tissue morphology and staining. Their qualitative nature and observer dependency remain a concern, and no classification exists for several significant conditions--for example, alpha1-antitrypsin deficiency (alpha1-ATD). The authors propose a disease- and morphology-independent numeric ranking system to objectively quantify fibrosis in a standard histologic section, based on its content of protein amino acids. This PNC system is applied to two cases of alpha1-ATD liver fibrosis. METHODS High-performance liquid chromatography separation of the 6-aminoquinolyl-N-hydroxysuccinimidyl carbamate (AQC)-labeled acid hydrolysate of an individual needle biopsy section, followed by the calculation of specific amino acid ratios to eliminate confounding variables. RESULTS As required by the PNC system, three numeric values were identified per tissue section, one increasing (P quotient), one decreasing (N quotient), one constant (C quotient) as fibrosis progresses, assessed by calibration against Knodell-staged samples. Generated for the alpha1-ATD sections, these three coordinates numerically referenced the degree of fibrosis in a manner that in each case was consistent with the histologic evaluation, the laboratory values, and the clinical course. CONCLUSIONS Numeric, objective referencing of the degree of fibrosis in routine liver biopsy sections, based on the PNC system, is technically possible.

Abstract
BACKGROUND Enteral tube and parenteral hyperalimentation are widely used nutritional support systems. Few studies examine the relation between nutritional support and patient outcomes in seriously ill hospitalized adults. OBJECTIVE To explore the association between nutritional support and survival in seriously ill patients enrolled in the Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments (SUPPORT). DESIGN A prospective study of preferences, decision-making, and outcomes. SETTING Five teaching hospitals PARTICIPANTS 6298 patients aged 18 or older meeting diagnostic and illness severity criteria. MEASUREMENT Demographic characteristics, diagnoses, comorbid conditions, acute physiology score, nutritional support, and functional status before hospitalization. RESULTS A total of 2149 patients received nutritional support. In patients who received artificial nutrition on hospital days 1 or 3 (Cohort 1), enteral feeding was associated with improved survival in coma (hazard: 0.53; 95%CI, 0.42-0.66), and reduced survival in COPD (hazard: 1.57; 95%CI, 1.18-2.08). In patients who were hospitalized on Day 7 and received artificial nutrition on days 1, 3, or 7 (Cohort 2), enteral tube feeding (hazard: 0.35; 95%CI, 0.27-0.46) or hyperalimentation (hazard: 0.58; 95%CI, 0.38-0.90) was associated with improved survival in coma. Tube feeding was associated with decreased survival in acute respiratory failure (ARF) or multiorgan system failure (MOSF) with sepsis (hazard: 1.21; 95%CI, 10.4-1.41), cirrhosis (hazard: 2.15; 95%CI, 1.35-3.42), and COPD (hazard: 1.37; 95%CI, 1.04-1.80). Hyperalimentation was associated with decreased survival in ARF or MOSF with sepsis (hazard: 1.34; 95%CI, 1.12-1.59). CONCLUSIONS Nutritional support was associated with improved survival in coma. Enteral feeding and hyperalimentation was associated with decreased survival in ARF or MOSF with sepsis. Tube feeding was associated with decreased survival in cirrhosis and COPD. Except for patients in coma, artificial nutrition was not associated with a survival advantage.

Abstract
PURPOSE To evaluate damage to cirrhotic liver tissue after transcatheter arterial chemoembolization (TACE) in patients with hepatocellular carcinoma (HCC). MATERIALS AND METHODS TACE was performed in 111 patients with HCC that involved less than 30% of the liver. Baseline liver function was evaluated with Child-Pugh scores and other indicators. Eighty-two patients had Child-Pugh class A disease, 27 had class B disease, and two had class C disease. All patients underwent chemotherapy followed by gelatin sponge particle embolization in the proper ("complete" embolization; n = 69) or right or left main ("partial" embolization; n = 42) hepatic artery. Liver function was assessed 4 months later, and 95 patients underwent a second TACE (complete embolization in 57, partial in 38). Liver function was again assessed 4 months later in 60 patients. RESULTS No patient died. Child-Pugh scores increased in all patients from a mean 5.96 to 6.28 (not significant) and 6.51 (P =. 05) after first and second TACEs, respectively. In patients with class A disease, scores increased from a mean 5.37 to 5.73 (P =.01) and 5.89 (P =.001) after first and second TACEs, respectively; in patients with class B disease, scores changed from a mean of 7.48 to 7.67 and 7.30 after first and second TACEs, respectively (not significant). CONCLUSION TACE does not induce significant long-term worsening of liver function in patients with class A or B cirrhosis.

Abstract
Prognosis of patients with cirrhosis and hepatocellular carcinoma (HCC) depends on both residual liver function and tumor extension. The CLIP score includes Child-Pugh stage, tumor morphology and extension, serum alfa-fetoprotein (AFP) levels, and portal vein thrombosis. We externally validated the CLIP score and compared its discriminatory ability and predictive power with that of the Okuda staging system in 196 patients with cirrhosis and HCC prospectively enrolled in a randomized trial. No significant associations were found between the CLIP score and the age, sex, and pattern of viral infection. There was a strong correlation between the CLIP score and the Okuda stage. As of June 1999, 150 patients (76.5%) had died. Median survival time was 11 months, overall, and it was 36, 22, 9, 7, and 3 months for CLIP categories 0, 1, 2, 3, and 4 to 6, respectively. In multivariate analysis, the CLIP score had additional explanatory power above that of the Okuda stage. This was true for both patients treated with locoregional therapy or not. A quantitative estimation of 2-year survival predictive power showed that the CLIP score explained 37% of survival variability, compared with 21% explained by Okuda stage. In conclusion, the CLIP score, compared with the Okuda staging system, gives more accurate prognostic information, is statistically more efficient, and has a greater survival predictive power. It could be useful in treatment planning by improving baseline prognostic evaluation of patients with HCC, and could be used in prospective therapeutic trials as a stratification variable, reducing the variability of results owing to patient selection.

Abstract
OBJECTIVE We conducted this study to describe the complications and validate the accuracy of previously reported prognostic indices in predicting the mortality of cirrhotic patients hospitalized for upper GI bleeding. METHODS This prospective, observational study included 111 consecutive hospitalizations of 85 cirrhotic patients admitted for GI bleeding. Data obtained included intensive care unit (ICU) admission status, Child-Pugh score, the development of systemic inflammatory response syndrome (SIRS), organ failure, and inhospital mortality. The performances of Garden's, Gatta's, and Acute Physiology and Chronic Health Evaluation (APACHE) II prognostic systems in predicting mortality were assessed. RESULTS Patients' mean age was 48.7 yr, and the median APACHE II and Child-Pugh scores were 17 and 9, respectively. Their ICU admission rate was 71%. Organ failure developed in 57%, and SIRS in 46% of the patients. Nine patients had acute respiratory distress syndrome, and three patients had hepatorenal syndrome. The inhospital mortality was 21%. The APACHE II, Garden's, and Gatta' s predicted mortality rates were 39%, 24%, and 20%, respectively, and their areas under the receiver operating characteristic curve (AUC) were 0.78, 0.70, and 0.71, respectively. The AUC for Child-Pugh score was 0.76. CONCLUSIONS SIRS and organ failure develop in many patients with hepatic cirrhosis hospitalized for upper GI bleeding, and are associated with increased mortality. Although the APACHE II prognostic system overestimated the mortality of these patients, the receiver operating characteristic curves did not show significant differences between the various prognostic systems.

Abstract
OBJECTIVE Symptoms associated with primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC) negatively affect health-related quality of life (HRQL). The aim of this study was to measure HRQL in patients with chronic cholestatic liver diseases and to determine factors associated with more severe impairment. METHODS We conducted a cross-sectional study in which we documented patients' demographic and clinical characteristics, and measured their HRQL using the Short Form-36 and Chronic Liver Disease Questionnaire. We assessed the association of HRQL impairment with disease severity (Child's-Pugh class and Mayo PBC Risk Score) and compared patients' HRQL with those of a healthy population, and patients with congestive heart failure, chronic obstructive pulmonary disease, and diabetes. RESULTS One hundred and four patients with PBC and PSC participated, of whom 73% were women, with an average age of 55+/-12 yr. Of these patients, 61% had cirrhosis (37% Child's A, 23% Child's B, and 2% Child's C). Patients with cholestatic liver disease showed more HRQL impairment than the healthy population and were similar to patients with other chronic conditions. Additionally, patients who experienced severe itching showed profound HRQL impairment. In patients with PBC, Physical Component Summary (PCS) scores of the SF-36 and Chronic Liver Disease Questionnaire (CLDQ) scores fell from noncirrhotic to Child's A to Child's B/C and with worsening Mayo PBC Risk Scores. No other clinicodemographic data were associated with patients' well-being. CONCLUSIONS Patients with cholestatic liver disease (PBC and PSC) showed substantial impairment of HRQL, which is further affected by worsening disease severity. Disease-specific measures were better able to discriminate patients with varying severities.

Abstract
OBJECTIVE Contrasting data are available on the natural history and bleeding risk of small esophageal varices. The aim of this prospective study was to evaluate a large series of consecutive cirrhotics with a first endoscopic diagnosis of small varices. METHODS Between 1987 and 1992, 258 patients with small varices and no previous bleeding were enrolled. Patients were clinically examined every 6 months and were followed until a first episode of bleeding and/or death, or until June 1998. None received any treatment to prevent bleeding. Endoscopies were planned at 18-month intervals. RESULTS The cumulative risk of bleeding was low (3% at 2 yr and 8% at 4 yr) and remained low in patients in whom varices remained small at 2nd endoscopy, whereas it increased significantly when varices enlarged. The increase of varices appeared to be rather linear in time: at the 2nd endoscopy varices remained small in 79% of patients and increased in 21%; at the 3rd endoscopy varices remained small in 55%, whereas at the 4th 33% of patients still had small varices. Clinical and biochemical data at the 1st and 2nd endoscopy were included in a multiple logistic regression analysis. Only the increase in Child-Pugh score appeared to be a significant predictor of enlarged varices; the risk of aggravation increased by 37.5% for every unit of impairment of the score. CONCLUSIONS The present study shows that patients with small varices have a low bleeding risk. An increase in Child-Pugh score during follow-up suggests enlargement of varices, thus an increase in bleeding risk. In these patients closer endoscopic surveillance is recommended.

Abstract
Surveillance for early detection of hepatocarcinoma (HCC) in patients with cirrhosis is widely accepted. In a cohort of 141 patients with cirrhosis collected during the year 1995, we conducted a surveillance program by performing liver ultrasonography and blood alpha-foetoprotein measurement every 6 months. The median follow-up was 34 months. This study addressed to two questions: the compliance to the surveillance schedule according to the aetiology of cirrhosis and the results in terms of emergence of HCC and outcome. Aetiology of cirrhosis was alcohol-induced in 86 (61%), HCV-related in 30 (21%) and from other origins in 25 (18%). Compliance to the program schedule was good in patients with HCV-related cirrhosis (29/30--97%) and patients with cirrhosis of "other origins" (20/25--80%) but was poor in patients with alcoholic cirrhosis (45/86--52%). The lack of compliance was significantly linked to the failure to achieve alcohol abstinence. During follow-up, 6 HCC lesions were observed in 6 male patients with median age of 68 years. All 6 HCC were single nodule, less than 4 cm and accessible to percutaneous acetic acid injection. Nevertheless, the outcome was disappointing, four patients dying 3-15 months later (median: 8 months), two of them with extensive HCC. One of the two patients still alive developed extensive HCC, 36 months after percutaneous acetic acid injection.

Abstract
OBJECTIVE Serum albumin is a key parameter for prognosis in cirrhosis. We compared levels of serum albumin determined by both protein electrophoresis and immunonephelometry, with special reference to the Child-Pugh classification. DESIGN AND METHODS One hundred and thirty-one patients, including 39 with cirrhosis, were included prospectively during 2 months. The aetiology of cirrhosis was mainly alcoholism (67%) and hepatitis C virus (HCV) (18%). Serum albumin was determined simultaneously by electrophoresis (Hydrasys SEBIA following protein determination by the biuret reaction) and by immunonephelometry (BECKMAN Nephelometer). Values were compared by non-parametric tests. RESULTS For the whole population, electrophoretic and immunonephelometric values correlated (p = 0.85; P < 0.0001), but electrophoresis significantly overestimated serum albumin by a median 1.6 g/l (P < 0.0001) with a large spread in values (range, -3.9 to 12.7). Median overestimation in cirrhosis was 2.6 g/l (P < 0.0001; range, -2.0 to 10.2) and 1.0 g/l (P < 0.0001; range, -3.9 to 12.7) in patients without cirrhosis (difference, P < 0.02). For 6/39 (15.4%) patients with cirrhosis, this overestimation led to an underestimation in the Child-Pugh classification. CONCLUSION In our experience, electrophoresis can lead to serum albumin values which are significantly different compared to those obtained by immunonephelometry. This discrepancy may lead to an incorrect Child-Pugh classification. Therefore, in the follow-up of cirrhotic patients, serum albumin should be determined by immunonephelometry.

Abstract
OBJECTIVE To study relation of serum fibrosis markers with quantitative analysis of liver tissue. METHODS We studied the area of reticular fibrin, collagen fibrin and elasticity fibrin in 77 patients with chronic liver disease using color image analysis system. RESULTS From S0 to S4, the area of three kinds of liver fibrosis were all escalate, especially collagen fibrosis. Prominent differences existed between S3 and S2, S2 and S1, S1 and S0. There was a good correlation between the serum fibrosis markers and area of collagen fibrosis of liver tissue, r = 0.70775(HA), 0.59402(CIV), 0.52593(LN), 0.52198 (hPCIII). CONCLUSIONS Serum fibrosis markers have affirmative value to help diagnose liver fibrosis.

Abstract
The characteristics of 70 cases of bacteremia in cirrhotic patients were studied according to the Child-Pugh classification as severity marker of liver involvement. Factors influencing on prognosis were determined. For a comparative analysis, 1,006 cases of bacteremia in non-cirrhotic patients were included. Sixteen patients corresponded to group A, 23 to group B and 31 to group C in the Child-Pugh classification. Patients in group A had a predominance of extra-enteric microorganisms, mainly Staphylococcus aureus (37.5%; p = 0.02), well-defined source (urinary tract, respiratory tract, skin) and good prognosis (mortality rate 6.2%). In contrast, patients in group C had a high recovery rate of Escherichia coli (41.9%) and pneumococcus (19.3%), undetermined source (51.6%; p = 0.05), ascites (83.9%), with or without concomitant peritonitis (41.1%; p = 0.03) and poor prognosis (mortality rate 48.3%; p = 0.008). The characteristics of patients in group B were similar to those of patients in group C but prognosis was as in patients in group A. The immediate mortality rate in the studied patients was 26%. The parameter which best predicted survival in the multivariate analysis was the Child-Pugh classification.

Abstract
We investigated the angiogenic phenotype of regenerative and dysplastic hepatocellular nodules to assess whether these lesions have distinct vascular profiles compared with the adjacent nonneoplastic or malignant liver. Forty-three liver nodules surgically removed from 18 patients were classified into regenerative and dysplastic categories. Serial sections of each nodule, adjacent cirrhotic liver (16 patients), and associated hepatocellular carcinoma (HCC) (6 patients), have been immunostained against CD31 and alpha-smooth muscle actin (alphaSMA) to detect capillary and muscular vessels. The study included 20 large regenerative nodules (LRNs), 13 low-grade dysplastic nodules (LGDNs), and 10 high-grade dysplastic nodules (HGDNs). The number of both capillary units and unpaired arteries was significantly increased in HGDNs and malignant lesions over LGDNs, regenerative, and cirrhotic nodules (P <.01), which showed an overlapping vascular profile. In addition, the number of capillary units, but not that of unpaired arteries, was significantly increased in HCC compared with HGDNs (P <.01). These results show that certain angiogenic features segregate HGDNs from other nonmalignant nodules such as LRNs and LGDNs. The former group of lesions is similar to HCC whereas the latter group is undistinguishable from the adjacent cirrhosis as far as their vascular profile is concerned. The adopted investigative approach does not support the morphological distinction between LRNs and LGDNs although it suggests that HGDNs are likely advanced precursors of HCC. An abnormal number of capillary units and/or unpaired arteries in a nonmalignant hepatocellular nodule can be diagnostically helpful to identify a precancerous lesion.

Abstract
OBJECTIVE Recently it has been recommended that all cirrhotic patients without previous variceal hemorrhage undergo endoscopic screening to detect varices and that those with large varices should be treated with beta-blockers (American College of Gastroenterology guidelines). However, endoscopic screening only of patients at highest risk for varices may be the most cost effective. METHODS Ninety-eight patients without a history of variceal hemorrhage underwent esophagogastroduodenoscopy as part of a liver transplant evaluation. Univariate/multivariate analysis was used to evaluate associations between the presence of varices and patient characteristics including etiology of liver disease, Child-Pugh class, physical findings (spider angiomata, splenomegaly, and ascites), encephalopathy, laboratory parameters (prothrombin time, albumin, bilirubin, BUN, creatinine, and platelets), and abdominal ultrasound findings (portal vein diameter/flow, splenomegaly, and ascites). RESULTS The causes of cirrhosis among the 67 men and 31 women (mean age, 48 yr) included 28% Hepatitis C/alcoholism, 25% Hepatitis C, 13% alcoholism, 9% primary sclerosing cholangitis/primary biliary cirrhosis, 9% cryptogenic, 6% Hepatitis B, 1% Hepatitis B and C, and 9% other. Patients were Child-Pugh class A 34%, B 51%, and C 15%. Endoscopic findings included esophageal varices in 68% of patients (30% were large), gastric varices in 15%, and portal hypertensive gastropathy in 58%. Platelet count <88,000 was the only parameter identified by univariate/multivariate analysis (p < 0.05) as associated with the presence of large esophageal varices (odds ratio 5.5; 95% confidence interval 1.8-20.6) or gastric varices (odds ratio 5; 95% confidence interval 1.4-23). CONCLUSIONS Platelet count <88,000 is associated with the presence of esophagogastric varices. A large prospective study is needed to verify and validate these findings and may allow identification of a group of patients who would most benefit from endoscopic screening for varices.

Abstract
OBJECTIVE The purpose of this study was to determine whether MR imaging can be used to grade the severity of cirrhosis. MATERIALS AND METHODS The MR examinations of 46 patients with cirrhosis were retrospectively reviewed independently by two radiologists and correlated with clinical severity assessed by Child-Pugh classification. MR imaging analysis by reviewers who were unaware of clinical status included comparison of volume indexes (computed as the product of three axis measurements) of the spleen and each segment of the liver, and changes in hepatic contour, iron or fat deposition, and presence of varices and collaterals. RESULTS Volume index of the spleen and the presence of ascites and varices were significantly and positively correlated (p = .008, .002, .0001, respectively) with the clinical severity of cirrhosis (Child-Pugh classifications), and volume indexes of the posterior, medial, and lateral segments of the liver were significantly and inversely correlated (p = .001, .049, .041, respectively). On an MR scoring system based on four items (volume index of the spleen; volume index of posterior + medial + lateral segments; presence of ascites; and presence of varices and collaterals), averaged total MR scores were 2.5 +/- 0.3, 4.9 +/- 0.6, and 7.9 +/- 0.8 for Child-Pugh grades A, B, and C, respectively (p < .0001). The accuracy of MR scoring in distinguishing between clinical Child-Pugh grade A cirrhosis and further grades was 89%, the sensitivity was 93%, and the specificity was 82%. CONCLUSION An MR scoring system can be used to grade the severity of cirrhosis.

Abstract
The ratio of serum aspartate aminotransferase to alanine aminotransferase (AST/ALT ratio) has been proposed as a noninvasive method of assessing liver fibrosis and cirrhosis. Our aims were to confirm the usefulness of the AST/ALT ratio in diagnosing cirrhosis noninvasively as well as to verify the existence of a relationship between the ratio and liver functional impairment. In all, 348 patients (177 with chronic hepatitis, 171 with cirrhosis) were retrospectively evaluated and the AST/ALT ratio was related to monoethyl glycine xylidide (MEGX) formation. Moreover, in a subgroup of 54 patients we analyzed the relationships among the AST/ALT ratio and indocyanine green clearance and half-life. The AST/ALT ratio was able to separate patients with mild fibrosis from those with severe fibrosis and cirrhosis. The AST/ALT ratio, MEGX, prothrombin activity, and platelet count were selected by multivariate analysis as variables associated with cirrhosis. The AST/ALT ratio showed significant correlations both with MEGX formation and with indocyanine green clearance and half-life. The alterations of indocyanine green kinetics, which depend upon liver blood flow and uptake, were likely due to progressive fibrosis. These findings might partially explain the increase in the AST/ALT ratio as disease progresses.

Abstract
Our institution is a tertiary referral center that specializes in hepatobiliary surgery. To evaluate the safety, efficacy, and conversion rate of laparoscopic cholecystectomy in patients with hepatic cirrhosis, we conducted a retrospective analysis of all cirrhotic patients undergoing attempted laparoscopic cholecystectomy during the period from 1991 to 1996. The diagnosis of cirrhosis was made on the basis of either a preoperative history, a liver biopsy, or the surgeon's operative description of the liver. All patients had early, well-compensated cirrhosis (Child's class A or B). A total of 30 patients underwent attempted laparoscopic cholecystectomy and five patients were converted to an open procedure (17%). The conversion rate for elective cases was 5% compared with 36% for urgent procedures. Two patients were converted because of varices and three because of unclear anatomy. No patients were converted because of bleeding. There were no operative deaths. The complication rate for elective procedures was 16%, with an average length of stay of 2.1 days, compared with 36% and 4.8 days, respectively, for urgent cases. Laparoscopic cholecystectomy in patients with early, well-compensated cirrhosis is safe and should be the treatment of choice for these patients.

Abstract
In the last decade there has been an evolution in the treatment of bleeding oesophageal varices. Endoscopic variceal ligation (EVL) is one of those new techniques that not only has shown to be more effective than sclerotherapy, but also causes less side effects, resulting in less episodes of rebleeding and improving survival. We describe severe bleeding in 3 patients after EVL, occurring between 5 and 10 days after the initial ligation. Two Child C patients could not be resuscitated and died shortly after this event. Severely impaired clotting function as a result of the liver disease and the greater size of the ulcers induced by EVL may contribute to this dramatic complication. Severe bleeding due to postligation ulceration may lead to death, which occurred in 2 of our Child C patients. Since more and more endoscopists are using EVL in the treatment of oesophageal variceal bleeding, they should be aware of the possible complications caused by this rather new technique.

Abstract
Assessment of hepatic function is based on both liver blood tests and functional tests, the extensive application of which is still controversial. The aim of this study was to evaluate the clinical utility of a few selected tests as discriminatory and prognostic indexes: serum albumin, pseudocholinesterase, prothrombin time, as well as galactose elimination capacity and hepatic sorbitol clearance. Two separate studies were performed: Study I to investigate how well these tests assessed severity, and Study II to evaluate their prognostic value. A total of 128 consecutive cirrhotic patients classified according to the Child-Pugh score were included in Study I; Study II was carried out on 47 of these 128 during a two-year follow-up period. Pairwise correlations between all tests and Child-Pugh score yielded higher significant values for liver blood tests than for the functional ones. In Study I functional tests such as galactose elimination capacity and hepatic sorbitol clearance did not appear to be better than conventional biochemical tests in discriminating clinical severity of cirrhotic patients, as defined by Child-Pugh classification. Results of Study II confirmed that in severe liver cirrhosis Child-Pugh score remains the best method for medium- and long-term prognosis and for planning liver transplantation. Functional tests should be reserved for defining the residual functioning liver mass or for studies about functional liver plasma flow.

Abstract
OBJECTIVE To evaluate prognostic factors after resection of hepatocellular carcinoma (HCC) in patients with Child-Turcotte class B and C cirrhosis. SUMMARY BACKGROUND DATA Although hepatic resection remains the mainstay in the treatment of HCC and can be performed with low morbidity and mortality rates in patients without cirrhosis, its role is poorly defined for patients with severe cirrhosis. METHODS From 1986 to 1996, partial hepatectomy was performed for HCC in 63 patients with Child-Turcotte class B (n = 46) and C (n = 17) cirrhosis. There were 46 men and 17 women, with an average age of 61.2 years (range 35 to 79 years). Associated conditions were diabetes mellitus in 45, esophageal varices in 32, severe hypersplenism in 26, cholelithiasis in 13, gastroduodenal ulcer in 6, and hiatal hernia, gastric lymphoma, splenic abscess, and pancreatic cyst each in 1. Concomitant surgical procedures were performed for most of these conditions. RESULTS Major complications occurred in 17 patients (27%), six (9.5%) of whom died within 1 month after surgery. The overall in-hospital death rate was 14.3%. Liver failure and intraabdominal sepsis were mostly fatal complications. The overall and disease-free survival rates, respectively, were 70.2% and 64.5% at 1 year, 43.5% and 23.8% at 3 years, and 21.4% and 14.9% at 5 years. Multivariate analysis with the Cox regression model revealed that favorable factors for survival were Child class B, no transcatheter arterial embolization before surgery, young age, and low alanine aminotransferase (ALT) level before surgery. CONCLUSIONS Hepatic resection can provide a favorable result in young patients with HCC complicating Child class B cirrhosis with low hepatitis activity, but transcatheter arterial embolization before surgery should be avoided in such patients.

Abstract
BACKGROUND Monoethylglycinexylidide (MEGX) formation following lignocaine injection has recently been proposed as a simple dynamic liver function test based on a single measurement of its serum concentration. AIM To determine the optimal sampling time for MEGX determination. METHODS A modelling analysis of lignocaine and MEGX kinetics was performed in seven normals and in four patients with compensated liver cirrhosis; a similar study was performed in 74 cirrhotic patients, divided into two groups according to disease severity (Pugh score). RESULTS Only the MEGX fractional formation rate (kf) and formation delay (tau) were significantly altered in cirrhotic patients compared to normals: kf = 0.15 +/- 0.03 vs. 0.32 +/- 0.10 min-1 (mean +/- s.d.); tau = 7.7 +/- 2.0 vs. 3.9 +/- 2.9 min-1. A good correlation was found between kf and late (r = 0.82) but not early (r = 0.63) serum MEGX formation, suggesting that late measurements for the clinical MEGX test are preferred. In the second part of our investigation, by discriminant analysis of MEGX test data for 74 cirrhotic patients, the late MEGX concentrations gave the best discrimination between the two classes. In particular, the 60 min MEGX concentration showed the best diagnostic accuracy (81%), sensitivity (75%) and specificity (84%). The association of this with other MEGX parameters, either singly or derived from the whole curve measurements, did not improve the performance of the method. CONCLUSION The MEGX test, based on a single determination 60 min after lignocaine injection, may be regarded as a simple and sensitive quantitative liver function test.

Abstract
Hepatocellular carcinoma is one of the most common malignancies world wide. We present data on 76 patients admitted to the Shaikh Zayed Hospital. Mean age was 52.2 +/- 11.3 years. Eighty six percent were males and 14% females. Eighty-six percent patients had underlying cirrhosis documented on ultrasound examination. Seventy-five percent were positive for anti HCV, 10% for HBsAg positive, 10% for both HBsAg and anti HCV and 5% cases had negative viral serology. Main clinical features were abdominal pain, weight loss, jaundice, hepatomegaly and ascites. Forty-three percent patients were Child-Pugh class A, 30% class B and 13% class C and 14% were non cirrhotic. Mean alfa fetoprotein levels were 142 +/- 155 ng/ml (range 2.7 to 1470). Diagnosis of hepatocellular carcinoma was established in 60 patients by fine needle aspiration biopsy under ultrasound guidance. Two patients died after biopsy due to uncontrollable bleeding. Fifty-four percent patients had a solitary lesion and 46% had multifocal or diffuse lesions. The average size of lesion was 7.8 x 8.1 cm. Twenty-two patients received intralesional alcohol injection. Fifty-four percent of these with a tumor size greater than 8 cm died during follow up. The major cause of death was liver failure in 8 patients and fatal bleeding occurred in 4 patients. Hepatocellular carcinoma has a high prevalence in middle aged males with a strong association with anti HCV positive cirrhosis. Patients with a tumour size greater than 8 cm have a poor response to intralesional alcohol injection.

Abstract
Serum alpha-fetoprotein (AFP) concentration was measured in 41 patients with different stages of liver cirrhosis demonstrated through scored Child-Pugh classification. Mean value was elevated up to 65.9 21.9 U/l, butstatistically significant difference in comparison with control group was observed only in patients classified as Child-Pugh C. AFP concentration revealed significant positive correlation with score values. Dynamics of AFP during one-year follow up demonstrated three-fold and statistically significant increase of its concentration, that was accompanied by elevation of mean score values.

Abstract
The aim of our study was to investigate local therapeutic effects and long-term results of combined transcatheter arterial chemoembolization (TACE) and percutaneous ethanol injection (PEI) in the treatment of large hepatocellular carcinoma (HCC). Eight-six patients (67 males and 19 females, age range 48-75 years, mean age 65.1 years) with Child-Pugh class A (n = 48) or B (n = 38) liver cirrhosis and a large HCC (main tumor 3.1-8 cm in diameter with no more than two daughter nodules) were enrolled in a prospective study. All patients underwent a single TACE session followed by PEI. Follow-up ranged from 4 to 65 months (mean 27.8 months, median 26 months). No major complication occurred. The local therapeutic effect, as assessed on the basis of findings at CT and MR imaging, was complete response in 71 of 86 patients (82 %) and partial response in 15 of 86. Overall survival rates by the Kaplan-Meier method were 92 % at 1 year, 83 % at 2 years, 69 % at 3 years, 58 % at 4 years, and 47 % at 5 years. Survival of Child-Pugh A patients (75 % at 3 years and 59 % at 5 years) was significantly longer (p < 0.01) than that of Child-Pugh B patients (61 % at 3 years and 35 % at 5 years). Combined TACE and PEI is an effective treatment for large HCC.

Abstract
BACKGROUND/AIMS Many hepatologists believe that the Child's classification is not the ultimate prognostic tool for liver disease. Our aim was to develop an index for the estimation of the severity of liver damage, to evaluate its predictive power for the short-term and long-term prognosis of patients with chronic liver disease, and for the estimation of the effect of different therapeutic regimens. METHODOLOGY The Liver Damage Score (LDS) was developed based on the analysis of the laboratory data of 151 randomly selected patients with liver diseases. Variables for reduced protein synthesis, increased production of antibodies, cytolysis, cholestasis, functional renal failure were combined into LDS according to the results of cluster analysis. The evaluation of the liver injury was analyzed in 696 patients with different liver diseases. RESULTS There are three groups of liver diseases: mild-with LDS of 1-2 U, moderate with LDS 3-4.5 U and severe with LDS > 5.0 U. There was a good correlation between the LDS and the scores for liver cirrhosis. Values above 4-6 U carry bad prognosis. The LDS truthfully reflects the evolution of liver diseases over time and the effect of therapy. CONCLUSION The LDS is a new, simple, low-cost, biomathematically and pathophysiologically based index, useful for monitoring practically all patients with liver diseases, no matter what the etiology and stage of the liver injury is. It allows a quantitative expression of the disease severity and the improvement or deterioration in its course.

Abstract
BACKGROUND The long term efficacy of combination therapy with transcatheter arterial embolization (TAE) followed by percutaneous ethanol injection (PEI) was studied in patients with large primary hepatocellular carcinoma (HCC) tumors and cirrhosis. METHODS The series included 83 patients with large unresectable HCC lesions, the largest of which was greater than 3 cm in largest dimension. Fifty-five had a solitary lesion and 28 had multiple (2 or 3) lesions. All patients were treated with both TAE and PEI and their survival rates were determined. RESULTS The 3-, 5-, and 7-year calculated survival rates for the patients were be 68%, 35%, and 14%, respectively. The number of lesions (solitary vs. multiple), the stage of cirrhosis (Child's Class A vs. Class B or C), and the size of the largest lesion (3-5 cm in largest dimension compared with > 5 cm) significantly affected the survival rate (P < 0.05 to P < 0.01, log rank test). The 3-, 5-, and 7-year survival rates of the Child's Class A patients who had a 3-5 cm solitary lesion (n = 22) were 100%, 75%, and 27%, respectively. The Cox proportional hazards model showed the stage of cirrhosis and size of the largest lesion to be independently associated with survival. No serious complications occurred during or after treatment. CONCLUSIONS Combination therapy with TAE and PEI is an effective and safe treatment that may improve the long term survival of patients with cirrhosis associated with large HCC lesions, and survival after this combination therapy may be comparable to that after surgery.

Abstract
BACKGROUND/AIMS A variety of severe illnesses can induce changes in thyroid hormone metabolism, leading to findings referred to as "sick euthyroid syndrome". In several groups of patients the reduction of serum thyroxine concentration (T4), characteristic of the low-T4 variant of sick euthyroid syndrome, has been found to be a good predictor of survival. Although the pathophysiology of hormonal alterations has not yet been defined, nutritional deficits have been suggested to play a role. The study aimed to define the prognostic and nutritional significance of serum thyroxine in liver cirrhosis. METHODS Thyroid hormones and nutritional status were evaluated in a group of 75 consecutive hospitalized patients with cirrhosis, followed-up clinically for 12 months. RESULTS A low-T4 variant of sick euthyroid syndrome was found in 23 of the 75 enrolled patients with cirrhosis (30.6%). Serum T4, but not serum T3, correlated with mid-arm muscle circumference (p < 0.01), an indicator of muscle protein compartment. While both serum T3 and T4 correlated directly with serum proteins and inversely with Child-Pugh score, only T4 was predictive of outcome. Patients with the low-T4 variant of sick euthyroid syndrome showed significantly lower short- and long-term survival rates compared to those with normal serum T4 concentrations (p < 0.008 at 3 months, p < 0.001 at 6 months and 1 year). A multivariate analysis using the proportional hazards Cox's regression procedure showed that serum T4, but not serum T3 or nutritional parameters, improves the prognostic capacity of Child-Pugh score (p < 0.01). CONCLUSIONS These data indicate that the low T4-variant of sick euthyroid syndrome distinguishes a subgroup of patients with cirrhosis at risk for decreased survival. The inclusion of T4 in the Child-Pugh score, by improving its prognostic power, may optimize the selection of patients with advanced cirrhosis to receive specific therapy such as transplantation.

Abstract
OBJECTIVE To classify elementary endoscopic lesions of portal hypertensive gastropathy, assess their reproducibility, prevalences, sensitivity and specificity in the diagnosis of cirrhosis of the liver. METHODS 1) A classification of portal hypertensive gastropathy elementary lesions was defined. 2) Thirty-two endoscopists evaluated videotapes of endoscopic examinations of patients with liver cirrhosis to assess beyond-chance agreement (kappa). 3) Fifteen centres enrolled consecutive patients with or without cirrhosis of the liver and recorded portal hypertensive gastropathy pattern according to its location. RESULTS 1) Four elementary lesions (Mosaic-Like Pattern, Red Point Lesions, Cherry Red Spots, Black-Brown Spots) were identified, and graded. 2) A fair to good beyond-chance agreement was obtained for all 4 lesions. 3) portal hypertensive gastropathy prevalence was higher in patients with cirrhosis of the liver (0.63, sensitivity) than in controls (0.17). Mosaic-like pattern was the most prevalent sign (0.54). Specificity of portal hypertensive gastropathy was 0.83. Portal hypertensive gastropathy was tentatively classified as mild or severe when mosaic-like pattern alone or red marks of any kind were present, respectively; this classification led to a further improvement in reproducibility. CONCLUSIONS Our results suggest that a sufficient degree of agreement can be achieved in recording portal hypertensive gastropathy. Therefore, the New Italian Endoscopic Club classification should be used to evaluate the natural history of this condition.

Abstract
OBJECTIVES This study was designed to characterize the splanchnic hemodynamic pattern and liver function in patients with cirrhosis and esophageal or gastric varices. METHODS Forty control subjects and 112 patients with cirrhosis were studied. Portal inflow (the sum of superior mesenteric arterial and splenic arterial flows), portal venous flow, and collateral flow (the difference between portal inflow and portal venous flow) were measured using duplex ultrasonography. Endoscopic examination showed that 45 patients had no varices or small esophageal or gastric varices, 49 had large esophageal varices, and 18 had large gastric varices. Liver function was assessed by Pugh-Child score. RESULTS Portal inflow was significantly greater in patients with large esophageal varices or large gastric varices than in control subjects and patients with no varices or small esophageal or gastric varices. Portal venous flow was significantly lower in patients with large gastric varices than in the other three groups. Collateral flow was significantly greater in patients with large gastric varices than in patients with large esophageal varices. The Pugh-Child score was significantly higher in patients with large gastric varices than in patients with large esophageal varices. The Pugh-Child score was also inversely correlated with portal venous flow (r = -0.35, p < 0.01) and directly correlated with collateral flow (r = 0.59, p < 0.01). CONCLUSIONS Both patients with esophageal varices and those with gastric varices have increased portal inflow. However, patients with gastric varices, in contrast to patients with esophageal varices, have a reduced portal venous flow associated with an increased collateral flow. Such a portal outflow pattern may contribute to the worse liver function seen in patients with gastric varices.

Abstract
BACKGROUND Hepatic transplantation and portasystemic shunts can be safely performed in patients with advanced liver disease, whereas other abdominal procedures appear to have a much higher mortality rate. This study reviews the outcomes of patients with cirrhosis after the full spectrum of abdominal operations. METHODS In a 12-year period, 92 patients diagnosed with cirrhosis required either an emergent or elective abdominal operation. There were four categories of operations: cholecystectomy in 17 patients, hernia in 9, gastrointestinal tract in 54, and other procedures in 12. Fifty-five clinical, laboratory, and operative variables were analyzed to identify factors predictive of poor outcome. RESULTS Coagulopathy developed in 24 patients (27%) and sepsis in 15 (16%). The mortality rate after emergent operations was 50%, compared to 18% for elective cases (p = 0.001). Other factors that predicted mortality included the presence of ascites (p = 0.006), encephalopathy (p = 0.002), and elevated prothrombin time (p = 0.021). The mortality in Child's class A patients was 10%, compared to 30% in class B and 82% in class C patients. CONCLUSIONS Patients with cirrhosis undergoing elective or emergent operations are at a significant risk of developing postoperative complications leading to death. The most accurate predictor of outcome is the patient's preoperative Child's class.

Abstract
BACKGROUND/AIMS The assessment of disease stage in cirrhosis is important for the individual patient (prognosis, timing and risk for requiring surgical intervention) and also for population comparisons and trials. There are several established methods, and we have aimed at comparison of the methods within a large cirrhosis population. METHODOLOGY In the European Union Euricterus database, there are 1015 patients with a "certain" diagnosis of cirrhosis, each of whom in one session had a protocol work-up of history, physical examination and all laboratory investigations needed for this study. The Child-Turcotte (CT), Campbell-Child (C) and Pugh-Child (P) classifications, as well as ascites/no ascites, ascites 1, 2, 3 (no, therapy responsive, nonresponsive) and ascites/nutritional state (ANS, 1-9) scores were used. CT and C have the same 5 variables, P has prothrombin time instead of nutritional state. CT, C and P variables score 1-3 each. C and P furthermore have variable range scores of 5-15. CT, C and P have classes A-C. The variables used were ascites, nutritional state, encephalopathy, bilirubin, albumin and prothrombin time. RESULTS Only 53 patients (5%) fit within the CT criteria. C and P variable range scores (5-15) correlated strongly (r = 0.84). Cross-over calculation showed slightly different results in the P and C choice of variables, while the variable ranges (1-3) did not matter. Different selection of score ranges for the A-C classes in C and P resulted in 69% class C in P (35% in C) and 3% A in P (19% in C). The patients with ascites (70%) had worse bilirubin, albumin, nutritional states and C and P 5-15 scores (p < 0.0001). Patients with ascites 3 had all variables and also C, P 5-15 scores worse than those with ascites 2 (p < 0.02). ANS scoring showed wasting in 33% of the patients without ascites (ANS 3), 50% of the patients with ascites 2 (ANS 6) and 60% with ascites 3 (ANS 9) (p < 0.0003), and C and P scores were higher in the 3 ANS scores with wasting. CONCLUSIONS Campbell and Pugh 5-15 scores correlated closely and can be used interachangeably. As C does not contain the more elaborate prothrombin time determination, it probably can be used anywhere in the world. Ascites (degree) and Ascites/Nutritional State (ANS) scoring only use history and physical examination and are, or remain, although less refined, clinically relevant.

Abstract
OBJECTIVE The aim of the study was to assess the utility of a modified three-parameter cirrhosis discriminant score (CDS) for diagnosing advanced fibrosis or cirrhosis in patients with evidence of chronic hepatitis C. METHODS We examined liver tissue from 79 patients. Patients with a histological fibrosis score of 0-2 made up group A, and patients with a score of 3 or 4 (advanced fibrosis or cirrhosis) group B. RESULTS The modified CDS (possible total score 0-11) was derived from three laboratory parameters: platelets, ALT/AST ratio, and PT. The total score was significantly lower in group A (4.3 +/- 2.0) than in group B (7.9 +/- 1.4) (p < 0.0001). There was a positive correlation between the CDS and histological fibrosis score (r = 0.64,p < 0.0001). With 8 or above as the cutoff value, the CDS had a sensitivity of 46% and a specificity of 98% for the diagnosis of histological fibrosis scores of 3 or 4. CONCLUSIONS We conclude that a three-parameter CDS is useful for identifying patients with hepatitis C and a high likelihood of cirrhosis. Patients with a CDS < or =7 still require histological examination to identify advanced fibrosis or cirrhosis.

Abstract
Noninvasive 13C-breath tests are used for the assessment of hepatocellular dysfunction. 13C-methacetin is metabolized in the liver by O-demethylation to 13CO2 and acetaminophen. The aim of the study was to evaluate the 13C-methacetin breath test in comparison to the Child-Pugh score and other quantitative liver function tests (MEGX-test and indocyanin green-clearance). 2 mg/kg 13C-methacetin were orally given to 31 patients with histologically proven liver cirrhosis of different etiology and severity (nine Child A, 13 Child B, nine Child C), ten patients with chronic viral hepatitis and ten healthy volunteers. The increase of exhaled 13CO2 was expressed as delta over baseline (DOB; delta /1000). Different DOB-values were compared as parameters for assessing hepatocellular dysfunction. All breath test parameters analyzed provided an excellent discrimination between cirrhotic and noncirrhotic individuals. The DOB-value at 20 min showed a superior correlation with the Child-Pugh score (r = 0.67) than did MEGX-test or indocyanine green clearance results (r = 0.39 and r = 0.43, respectively). With a cut-off value of < or = 25 delta /1000 at 20 min, sensitivity and specificity to discriminate between cirrhotic and noncirrhotic individuals was 93.5% and 95%, respectively. The 13C-methacetin breath test is a safe and precise quantitative liver function test. Using one single breath sample 20 min after substrate administration, the test discriminates well between cirrhotic and noncirrhotic patients. Its prognostic value remains to be established.

Abstract
OBJECTIVES Portal hypertensive colonopathy is observed in patients with liver cirrhosis. To determine the correlation between rectal mucosal hemodynamics and portal hypertensive colonopathy, we observed rectal mucosal findings and measured rectal mucosal hemodynamics in patients with liver cirrhosis. METHODS Thirty-four patients with liver cirrhosis and 16 healthy control subjects were simultaneously examined for rectal mucosal findings by colonoscopy and indices of rectal mucosal Hb concentration (RHb) and rectal mucosal oxygen saturation by reflectance spectrophotometry. Endoscopic findings in the rectal mucosa of patients with liver cirrhosis included vascular ectasias, blue veins, and varices. We investigated the relationship between rectal mucosal hemodynamics and clinical parameters of liver cirrhosis (Child-Pugh classification, the amount of indocyanine green remaining in the blood 15 min after its injection, and ascites). Patients with hepatocellular carcinoma, colonic cancer, multiple colonic polyps, or severe anemia were excluded. RESULTS Rectal mucosal lesions were observed in 11 patients with liver cirrhosis (32.4%). In the hemodynamic studies, we found significantly increased RHb values in the cirrhosis group as compared with the control group. On the other hand, there was no significant change in rectal mucosal oxygen saturation between the two groups. A significant increase in RHb was observed in patients with rectal mucosal lesions in the cirrhosis group. RHb in the cirrhosis group correlated with grade of Child-Pugh classification. Increased RHb decreased in parallel after portal decompression by creation of a transjugular intravenous portosystemic stent shunt. CONCLUSIONS The rectal mucosal lesions in liver cirrhosis correlate with an increase in RHb, which correlates with portal hypertension.

Abstract
Bleeding from esophageal varices is the major cause of death in patients with portal hypertension. The ideal surgical procedure should effectively control bleeding, with as little impairment of liver function as possible and with low rates of encephalopathy. Based on this objective, we propose the azygoportal disconnection (APD) with splenic artery ligation, and suturing of the gastric and esophageal varies without opening the esophagus, by video laparoscopy. With the patient placed in a semigynecologic position, we use five trocars, and the intervention begins by dissection of the diaphragmatic hiatus and isolation of the esophagus. Then devascularization of the gastric fundus is accomplished. After that, dissection and ligature between clips of the splenic artery are performed. The surgery proceeds with dissection and ligation of the vessels of the lesser curvature. After orally introducing a 12-mm Fouchet probe, we suture the varices of the distal esophagus transmurally, with interrupted sutures. The procedure is accomplished with a floppy Nissen valve. Between March 1994 and May 1995, four patients were treated with this method, two men and two women with a mean age of 54 years. All of them had hepatic cirrhosis. Three patients were classified Child B and the other Child C. Surgical indication in all subjects was persistent bleeding of the esophageal varices, after failure of such clinical attempts as endoscopic sclerosis and tamponade with the Sangstaken-Blakemore balloon. The operation mean time was 177 min. Neither bleeding nor hemodynamic changes occurred during the surgery. The patients were sent to the intensive care unit (ICU) postoperatively for a mean time of 3 days, and they were discharged from the hospital between days 8 and 10. The evolution demonstrated stabilization of the hepatic function and regression of the varices from grades III and IV to grade I. No bleeding recurred. Although this study had a small number of patients, we believe that this operation made by mini-invasive technique permits a quick recovery, reducing the global morbidity of this procedure.

Abstract
The presence of increased amount of ligands for benzodiazepine receptors has been demonstrated in cirrhotic patients. Evoked potentials (EP) recordings are a simple, suitable, and objective method for comprehensive evaluation of hepatic encephalopathy (HE). We evaluated the visual EP, brain stem auditory EP, and somatosensory EP (SSEP) and the effect of benzodiazepine receptor antagonist flumazenil in patients with liver cirrhosis. EP of 38 patients with liver cirrhosis were recorded on the electrodiagnostic system Neuropack 8 (JB-441 B, Nihon Kohden). Eleven patients (nine males and two females; mean age 60 years; six with stage 0,4 with stage one, and one with stage 2 HE) showed impairment in SSEP N13-N19 interval. After baseline period, boluses of 1 mg, 2 mg, and 3 mg flumazenil were injected every thirty minutes and SSEP recordings were repeated after every dosage. We did not find any difference before and after flumazenil in SSEP N13-N19 interval (7.3 +/- 0.4, 7.1 +/- 0.5, 7.1 +/- 0.4, and 7.1 +/- 0.6 minutes, respectively) (p < 0.05). But four patients (36%) showed a clear SSEP improvement with flumazenil. Our results suggest that in a subset of cirrhotic patients, flumazenil may have a role.

Abstract
We estimated the validity, i.e., whether the diagnostic criteria were fulfilled for the patients registered with the diagnosis of liver cirrhosis in a Danish hospital discharge registry, and the completeness, i.e., whether all patients with liver cirrhosis were included in the registry. Information in the regional hospital discharge registry in the Country of Aarhus, Denmark was compared with hospital records and information in a pathology registry. 85.4% of the patients registered with a diagnosis of liver cirrhosis fulfilled the diagnostic criteria for the diagnosis (validity). 93.2% of the patients registered with biopsy proven liver cirrhosis in the pathology registry were found in the discharge registry (completeness) with a diagnosis of liver cirrhosis. The hospital discharge registry showed relatively few misclassifications and the Danish National Registry of Patients (NRP), which is based on the regional registries, may provide a unique study base for future research.

Abstract
OBJECTIVES Our aim was to determine whether tissue factor pathway inhibitor (TFPI), a physiologically important natural anticoagulant that acts by inhibiting the extrinsic pathway, concentrations decrease as liver disease progresses, and, second, whether TFPI has an etiologic role in portal vein thrombosis in cirrhotics. METHODS After taking their informed consent, we determined TFPI concentrations in the plasma of healthy subjects (group I) (n = 15) (average age, 45.1 = 11.8 yr), cirrhotics (group II) (n = 16) (average age, 43.6 +/- 9.8 yr), and cirrhotics with portal vein thrombosis (group III) (n = 12) (average age, 42.6 +/- 10.7 yr). Mean and median TFPI values and interquartile ratios were determined for groups I, II, and III. Then group II and III were further divided according to the Child classes A, B, or C, and mean and median TFPI values and interquartile ratios were determined for these classes as well. Using the Man-Whitney U test, we compared the results. RESULTS Statistically important differences were documented (p = 0.005) between the median TFPI levels of healthy adults and Child C cirrhotics (concentration lower in Child C) and between normal subjects and cirrhotics with portal vein thrombosis (p = 0.02) (TFPI concentration being lower in the latter group again). CONCLUSIONS TFPI concentration decreases in advanced liver disease, and this may be a contributory factor for portal vein thrombosis in at least some cases of cirrhotics.

Abstract
Differential diagnosis of liver parenchyma disease and grading of the hepatic disease on ultrasound is a common radiological problem that influences patient management. The aim of this study was to apply image analysis methods on ultrasound images for discriminating liver cirrhosis from fatty liver infiltration and for grading hepatic disease, which is important in the management of the patients. Ultrasound images of histologically confirmed 18 livers with cirrhosis, 37 livers with fatty infiltration, and 24 normal livers of healthy volunteers were selected and were digitized for further computer processing. Twenty two textural features were calculated from small matrix samples selected from the ultrasound image matrix of the liver parenchyma. These features were used in the design a three level hierarchical decision tree classification scheme, employing the multilayer perceptron neural network classifier at each hierarchical tree level. At the first tree level, classification accuracy for distinguishing normal from abnormal livers was 93.7%, at the second level the accuracy for discriminating cirrhosis from fatty infiltration was 90.9%, and at the third level the accuracy in distinguishing between low and high grading liver cirrhosis or fatty infiltration was 94.1% and 84.9% respectively. The proposed computer software system may be of value to the radiologists in assessing liver parenchyma disease.

Abstract
OBJECTIVE To test prospectively whether serum laminin levels, which is taken to indicate portal hypertension, can predict the occurrence of severe complications in advanced cirrhosis of the liver. PATIENTS AND METHODS In 38 patients (21 men, 17 women; mean age 55.6 +/- 13.4 years) with liver fibrosis (n = 4) or liver cirrhosis (n = 34) serum laminin was measured by a commercially available radioimmunoassay (Behring, Marburg). The severity of liver cirrhosis was graded according to the Child-Pugh-Christensen criteria. Portal hypertension was assessed by standard endoscopic methods and portal-vein duplex sonography. Within a mean observation period of 12.5 +/- 3.5 months, the following were used as signs of severe clinical complications of liver cirrhosis: stages III and IV of hepatic coma, treatment-refractory ascites, portal vein thrombosis and death due to multi-organ failure. Acute bleeding from oesophageal varices was confirmed by emergency endoscopy. RESULTS At laminin concentrations of 3.25 +/- 0.20 U/ml there was a highly significant correlation (P < 0.001) with complications of liver cirrhosis. Using 2.6 U/ml as the critical level, the occurrence of severe complications had a positive predictive value of 0.80 with a sensitivity and specificity of 0.71 and 0.86 respectively. This means that a patient who, at the beginning of the study period, had a raised laminin concentration, had a relative risk of 2.65 (1.41-4.97) for later severe complications. CONCLUSION Serum laminin concentration has a diagnostic efficiency of 0.79 as a prognostic indicator and can thus serve as a valuable addition to the Child-Pugh-Christensen classification of liver cirrhosis.

Abstract
AIM OF THE STUDY In the recent literature it has been emerged the importance of grading and staging of chronic viral hepatitis. Numerous different methods of grading and staging have been proposed. Purpose of the present paper was to compare the methods proposed by Knodell et al., Scheuer, and Ishak et al. MATERIALS AND METHODS Forty consecutive cases of chronic viral hepatitis constituted the basis of the study. Each case was graded as mild, moderate and severe activity and staged according to the criteria described in the three methods. In particular portal-periportal activity, lobular activity and fibrosis were evaluated. The final evaluation of the liver biopsy, together with the result of each single feature, were then compared. RESULTS The three different methods gave grossly similar results in the overall grading of the cases. Analyzing the single features, differences were noted in the evaluation of the lobular activity. This is probably the consequence of the different qualitative and quantitative criteria applied. Comparison of the data obtained by evaluating the extension of fibrosis was quite difficult, owing to the extremely different scales of grading used in each single method. CONCLUSIONS In this study three different methods of grading and staging of chronic viral hepatitis were compared. The final evaluations of the cases obtained with the different methods were almost superimposable. Comparing the data obtained with long term follow-up of the patients may better clarify which of the different methods can have a prognostic value.

Abstract
Malnutrition frequently occurs in patients with liver cirrhosis independently for its aetiology and can modify prognosis of the disease. We have evaluated if malnutrition can affect the survival of 184 patients with liver cirrhosis (124 at stage A according to Child-Pugh criteria, and 50 at stage B-C of the disease). Nutritional status was assessed by anthropometric measurements: body weight (actual and ideal), and biceps, triceps, over-iliac and sub-scapular skinfold thickness. About 8% of Child A patients and 26% of Child B-C were malnourished, and malnutrition affected the mortality of these patients at 1 year, whereas no differences were observed at 2 years. Our data suggest that the evaluation of nutritional status is important in cirrhotic management and malnutrition can be an aggravating factor for the survival of these patients.

Abstract
Prognosis for acutely ill patients with cirrhosis is influenced by the severity of hepatic abnormalities and by dysfunction of other organ systems. The purpose of this study was to examine the usefulness of the Acute Physiology, Age, and Chronic Health Evaluation (APACHE III) prognostic system for risk-stratifying groups of intensive care unit (ICU) patients with cirrhosis and in predicting individual survival. We used data for 17,440 ICU admissions at 40 American hospitals to select 117 of the 537 patients with a history of cirrhosis who were ventilated on ICU day 1, a group known to have a high mortality rate. We then calculated each patient's probability of hospital death on ICU days 1 through 7, using seven previously validated multivariate equations. Hospital mortality was 63% for the 117 study patients. The most important determinants of risk for hospital death on ICU day 1 were the acute physiology score of APACHE III, ICU admission diagnosis, and operative status. Daily changes in the acute physiology score caused a rise or fall in the probability of hospital mortality and was useful in assessing individual response to therapy. APACHE III accurately risk stratifies critically ill patients with cirrhosis because it accounts for many of the factors known to influence prognosis. This capability can be used to assess severity of illness and risk-stratify patients with cirrhosis during clinical trials. Daily prognostic estimates based on physiological changes over time reflect patient response and can help physicians to assess the incremental benefit of therapy.

Abstract
OBJECTIVE To find the most adequate prognostic scoring system for predicting ICU-outcome in patients with decompensated liver cirrhosis in a medical intensive care unit (ICU). DESIGN Retrospective analysis of patients' records over a 10-year period. SETTING A medical ICU at the university medical center of Vienna. PATIENTS AND PARTICIPANTS 94% (n = 198) of all patients with cirrhosis admitted to our medical ICU throughout the 10-year study period. INTERVENTIONS None. MEASUREMENTS AND RESULTS From data obtained at admission and at 48 h after admission, scores were calculated using the following scoring systems: Acute Physiology and Chronic Health Evaluation (APACHE) II and III, Scale for Composite Clinical and Laboratory Index Scoring (CCLI), Mayo Risk Score, and Child's Classification. Statistical analysis for the prognostic variables was performed using the chi-square test, t-test, Youden index, and area under a receiver operating characteristic (ROC) curve. APACHE III was found to be the most reliable outcome predictor at admission and after 48 h for patients with decompensated liver cirrhosis (AUC = 0.75 and 0.8, respectively). CONCLUSIONS To predict the outcome for patients with decompensated cirrhosis of the liver admitted to a medical ICU liver failure alone is not decisive. Liver-specific scoring systems (Mayo Risk Score, CCLI) are adequate, but the APACHE II and III proved to be more powerful, because they include additional physiologic parameters and therefore also take into account additional complications associated with this liver disorder.
