A number of pitfalls can be encountered in the interpretation of common blood liver function tests. These tests can be normal in patients with chronic hepatitis or cirrhosis. The normal range for aminotransferase levels is slightly higher in males, nonwhites and obese persons. Severe alcoholic hepatitis is sometimes confused with cholecystitis or cholangitis. Conversely, patients who present soon after passing common bile duct stones can be misdiagnosed with acute hepatitis because aminotransferase levels often rise immediately, but alkaline phosphatase and gamma-glutamyltransferase levels do not become elevated for several days. Asymptomatic patients with isolated, mild elevation of either the unconjugated bilirubin or the gamma-glutamyltransferase value usually do not have liver disease and generally do not require extensive evaluation. Overall hepatic function can be assessed by applying the values for albumin, bilirubin and prothrombin time in the modified Child-Turcotte grading system.

Cholelithiasis in infants and children is unusual and is reputedly associated with underlying hemolytic disorders, total parenteral nutrition, ileal disease, and congenital anomalies of the biliary tree. We report a case of cholecystitis with pigmented stones in a 3-month-old infant associated with portal vein thrombosis (PVT) and biliary cirrhosis without the above-mentioned causes. Recanalization of the PV and partial resolution of the cirrhosis was observed following cholecystectomy. To our knowledge, cholelithiasis associated with PVT and cirrhosis in an infant has not been reported in the literature.

Hepatobiliary dysfunctions (TPN-HBD) occur during parenteral nutrition. In older children these are usually reversible whereas in newborns and infants these hepatobiliary abnormalities play a significant role in the morbidity. Cholestasis is a commonly occurring TPN-HBD. It correlates directly with the decreasing gestational age, low birth weight and increasing duration of TPN therapy. The pathogenesis of cholestasis of TPN is multifactorial and predisposed by necrotising enterocolitis, sepsis, cardiac failure, shock, and hypotension. Diagnosis is made with exclusion of other causes of direct hyperbilirubinemia. Most TPN-HBD appear within 4 weeks of starting of TPN but severe complications manifest usually after the 16th week. Histologically there is intralobular cholestasis. In few cases there may be severe portal fibrosis followed by development of micronodular biliary cirrhosis. Enteral starvation, defective bile acid carriers, hypercaloric TPN are the major factors responsible for TPN-HBD, including cholestasis. Biliary complications of TPN-HBD are acalculous, cholecystitis, and cholelithiasis. Bile stasis is a major pathological factor for these. If the calories are provided only by glucose or glucose-containing electrolyte solutions it may lead to cholestasis and other TPN-HBD. Even small oral alimentation (continuous or bolus) during TPN, prevent TPN-HBD. Choleretic agents have been useful in the prevention and management of cholestasis and other parenteral nutrition induced hepatobiliary abnormalities.

Gallstones are seen in 33-46% of patients with cirrhosis, and their prevalence is known to increase with the duration and severity of liver disease. We hypothesized that autonomic neuropathy may contribute to the formation of gallstones or gallbladder disease, as in diabetics with autonomic neuropathy, due to impaired gallbladder emptying. The objective of our study was to determine the prevalence of gallstones or gallbladder disease in cirrhotic patients with and without autonomic neuropathy. We determined autonomic function tests, gallstones, and other gallbladder disease in 123 (male 71) with varying severity of liver disease (Child classes: A, 40; B, 45; C, 35). In all, 54 patients had gallstones and an additional 22 patients had other gallbladder disease (cholecystitis, common bile duct stones, or debris). Autonomic neuropathy was seen in 97 patients (one abnormal test in 48 and two or more in 49). The prevalence of gallstones was similar in Child A (57%), Child B (64%), and Child C (63%) cirrhosis. The gallstones or gallbladder disease was not increased in women, blacks, diabetics, or alcoholic cirrhotics. The prevalence of gallbladder disease was increased in patients with autonomic neuropathy (51% vs 35%, P = 0.08); in patients with Child C cirrhosis, gallstones (P = 0.018) and gallbladder disease (P = 0.03) were seen more commonly in patients with autonomic neuropathy. Our findings suggest that autonomic neuropathy may contribute to the formation of gallstones in patients with advanced cirrhosis, perhaps by impairing gallbladder and sphincter of Oddi dysmotility.

The authors evaluated the results assembled in 5397 patients where between Jan. 1 1999 and Oct. 31 2000 sonographic examinations of the abdominal cavity and retroperitoneum were made with the objective to assess whether there are any statistically significant differences of results in diabetic patients, as compared with a group without this disease. The group of patients was divided into a sub-group of 4287 patients without diabetes and a sub-group of 1100 diabetics. For statistical evaluation of the significance of differences in the incidence of the investigated parameters Fisher's exact test was used. The image of "light liver" was significantly more frequent in diabetics type 1 and 2, as compared with non-diabetics (p < 0.001). The sonographic picture, consistent with the diagnosis of cirrhosis of the liver, was at the same level of significance more frequent in non-diabetics, similarly as the incidence of haemangioma. The finding of cholecystolithiasis and the number of patients with a history of CHCE on account of cholecysolithiasis was significantly higher (p < 0.05) only in type 1 diabetics as compared with non-diabetics. The incidence of sonographic changes consistent with acalculous cholecystitis was statistically higher in both groups of diabetics (p < 0.001), as compared with non-diabetics. On examination of the pancreas only the incidence of changes consistent with acute or chronic pancreatitis was significantly higher (p < 0.05) in the group of type 2 diabetics as compared with non-diabetics. Evaluation of sonographic findings of the kidneys revealed statistically significant differences only in the higher incidence of cysts in the group of type 2 diabetics as compared with type 1 diabetics and as compared with non-diabetics (p < 0.01). The impact of the presented findings and their comparison with data reported in the literature is discussed.

The use of helical CT, infusing pump and non-ionic contrast media has enabled the evaluation of different hepatic circulatory phases during contrast injection. Starting the acquisition of scans 20 to 30 seconds after the injection at a rate of 3 to 4 ml/sec the arterial enhancing of the liver is depicted. THROMBOSIS OR COMPRESSION OF THE PORTAL VEIN: Hypervascular triangle-shaped was with peripheral base can be seen, secondary to the increased arterial flow to compensate for the diminished portal flow. ARTERIOPORTAL SHUNTS: This condition can be caused by tumors such hepatocellular adenocarcinomas and hemangiomas, trauma, interventional procedures, cirrhosis, AVMs and surgery. INFLAMMATORY LESIONS: Hypervascular areas can be seen during the arterial phase in abscesses or cholecystitis, returning to their normal condition in the arterial phase. ANATOMIC VARIANTS: Third veins coming from the periphery (capsular veins, accessory cystic vein and an aberrant gastric vein) supply enhanced blood earlier than the portal circulation. OTHER CAUSES: In liver cirrhosis diffuse hyperattenuated areas can be seen during the arterial circulation. In right-sided heart failure, pericardial disease and Budd-Chiari Syndrome, "mosaic areas" can also be noted. In other patients these perfusion disorders were considered unknown. TUMORS: The well-differentiated hepatocellular carcinoma is a lesion with a predominant arterial blood supply, thus appearing in general hyperdense in this phase. Hemangiomas may appear as highly hyperdense lesions in the arterial phase and can be misinterpreted as HCC if smaller than 2 cm. (30% of cases). Focal nodular hyperplasia is a benign lesion (vascular malformation associated with focal nodules of hepatocellular hyperplasia) with increased arterial blood supply. Hepatic adenomas show an important hypervascularity during the arterial phase and, if large, they may present a small central scar and or capsule. Low or high-grade dysplastic nodules can sometimes be seen as hypervascular areas during the arterial phase. Although most metastasis are depicted as hypodense lesions sometimes they can show arterial hypervascularity such as carcinoid and pancreatic islet cell metastasis.

There is analysis of liver and biliary tract diseases epidemiology in Moscow during 1993-1998 years. The data of Moscow Health Department's Medical Statistical Bureau were used. The diseases of digestive system (diseases are in percents) are 9.3% of common diseases among the adults persons (18 years old and more) in Moscow, and are 8.1% in teenagers. (15-17 years old). Increase of the diseases of digestive system prevalence was demonstrated in Moscow during this time from 10,692 to 13,929 for 100,000 persons among adults and from 9251 to 12,496 among teenagers. Morbidity of the diseases of digestive system was increased among adults from 1550 to 1953 and from 2512 to 3312 among teenagers at the same time. Prevalence of cholangitis among adults was increased on 40.8% at the same time. This index in teenagers is high as well, but it isn't even. The most high increase was demonstrated in 1997 year (821 cases for 100,000 teenagers). Increase of cholelithiasis, cholecystitis and cholangitis morbidity among the adults and teenagers was 66.2% and 73.1% accordingly in 1997 year. Prevalence of chronic liver diseases and liver cirrhosis was increased on 104.9% (in two times) during 6 years (1993-1998). Morbidity of these diseases was increased in 2 times as well at the same time.

Identification, evaluation and treatment of liver disease are increasingly important challenges in children with cystic fibrosis (CF). Liver disease usually presents at puberty and is receiving more attention with improved life expectancy. The abnormal CF transmembrane regulator protein in the apical surface of the biliary epithelium causes the disease. Hyperviscous bile accumulates in the biliary tree causing cholangiocyte and hepatocyte injury, stimulating focal fibrosis. Fibrosis is thought to lead on to cirrhosis over a period of years, a process which is usually asymptomatic. Steatosis and biliary tree anomalies including cholecystitis also occur. Clinical signs of liver disease appear late, by which time cirrhosis may be established. Early diagnosis would allow interventions to be evaluated but there is no gold standard for screening. Currently, regular clinical assessment, measurement of liver enzymes, ultrasound and liver biopsy are all used to evaluate liver disease in CF. Bile acid therapy reverses many markers of the disease but there is no good evidence that progression to cirrhosis can be prevented. A few children with cirrhosis decompensate (demonstrated by falling plasma albumin or coagulopathy) but they do well with liver transplantation. Children with portal hypertension as the sole manifestation of CF liver disease can be effectively managed with a programme of variceal obliteration or porto-systemic shunts.

We made a study in 1st Surgery Clinic of Iassy between March 93--November 98, with 2246 laparoscopic cholecystectomies. The reason was to define the place and role of laparoscopy in non-lithiasis cholecystopathies (81 cases). In the same period were operated classically 888 calculous cholecystitis and 38 non-lithiasis cholecystitis. The laparoscopy has a major role in diagnosis to the patients with many abdominal symptoms. We discovered pericholecystic adherences, hepatic cirrhosis, acute appendicitis, etc. Sometimes, the laparoscopy was made for "second look" after surgical treatment for neoplasia, the metastasis diagnosis, for tumors visible echographically. In many situations the laparoscopic cholecystectomy may be considered like a preventive operation. The easy postoperative evolution is an argument to enlarge the indication for laparoscopic cholecystectomy in alithiasis cholecystitis.

Acquired factor X deficiency has been described in patients with amyloidosis but acquired factor V deficiency is quite rare. We report here a case of life-threatening bleeding and acquired factor V deficiency associated with primary amyloidosis. A 50-year-old man who had no previous hemorrhagic diathesis was referred to our hospital because of recurrent epistaxis, gingival bleeding and hemospermia. The laboratory examination revealed that both the prothrombin time (PT) and the activated partial thromboplastin time (aPTT) were significantly prolonged, and factor V activities were markedly decreased to 14-39% of the normal value. Other coagulation factors such as fibrinogen, prothrombin, factor VII, factor VIII, factor IX and factor X were subnormal and normal. Transaminases were slightly elevated but serological tests of hepatitis B and hepatitis C were negative. Mild hepatosplenomegaly was noted without sign of liver cirrhosis. The PT and aPTT obtained 8 years ago when he received a cholecystectomy due to cholecystitis were both normal. Specific assays for the detection of factor V inhibitor were repeatedly performed but no factor V inhibitor was found. Furthermore, a significant recovery of the infused factor V was noted shortly after an intravenous administration of 5-10 U fresh frozen plasma, but it did not last more than 6 h. Melena, bleedings into the left shoulder and buttock, and finally mortal retroperitoneal hemorrhage developed despite repeated infusions of large amounts of fresh frozen plasma. Acquired factor V deficiency associated with primary amyloidosis was suspected but histological diagnosis was not obtained because of the severe bleeding tendency. Autopsy revealed hepatosplenomegaly and massive deposits of AL amyloid in the liver, spleen, heart and other parenchymal organs. Perivascular amyloid deposition and factor V deficiency are both thought to be the cause of the severe hemorrhagic tendency seen in this patient.
