A group of 165 geriatric patients is compared with a control group of 114 younger patients concerning different frequency of laparoscopic diagnoses. As it was suspected from the clinical view aged patients predominently suffered from posthepatic cirrhosis and from cirrhosis of unknown origin, from recurrent cholecystitis, obstructive jaundice, metastases and carcinosis of peritoneal cavity. Younger patients much more frequently showed toxic liver damage starting from fatty liver and ending up with fatty liver cirrhosis. Persistent acute hepatitis non associated with HBSAg was scarcely seen with the aged group. It was a frequent diagnosis with the younger control group. There are explanations given for the differing endoscopic results concerning aged persons and younger control persons.

Ultrasonic and scintigraphic examination of the liver took place in 148 patients. 29 had normal livers, 36 had cirrhosis, 11 had obstructive jaundice, 12 had fatty livers, 60 had focal liver defects. In case of diffuse liver disease the accuracy of both methods is about the same except for fatty liver which is poorly diagnosed by scintigraphy. Focal liver disease is determined with a relative high percentage false-negative for scintigraphy and a relative high percentage false-positive for echography. It is recognized that previous knowledge of the scintigraphic result may raise the accuracy of ultrasound examination of the liver. As echography could distinguish cystic from solid lesions both methods of liver imaging are considered complementary.

In the course of 4 years, among 11,738 admissions there were 245 (2.08%) patients with cholestasis (106 women and 139 men). Intrahepatic cholestasis (i.c.) was detected in 46.5%, and extrahepatic (e.c.) in 53.5%. The most frequent cause of i.c. were alcoholic and nonalcoholic chr. liver disease (fatty liver, chr. hepatitis, cirrhosis) (37% and 30%), acute viral hepatitis (15%) and toxic liver injury (14%) respectively. The causes of e.c. were: choledocholithiasis (44%), cancer of the pancreatic head (15%), cancer of gallbladder and extrahepatic ducts (12%) and cancer of liver (10%). The causes of c. were benigne, in 78.2%, while malignant neoplasms were present in 21.8%. Out of the multitude of laboratory tests two appeared particularly significant: glut, transpeptidase was pathologic in 81% of alcoholic liver disease, in 62% of the cases with obstructive jaundice and in 27.7% of malignant neoplasms. LX-lipoprotein examined in 52 patients was positive in 24% of i.c., and 60% of e.c. Proliferation of bile ducts was the most frequent finding in surgical liver biopsies in choledocholithiasis cases.

Thin needle cholangiography (TNC) was performed in 50 patients with obstructive jaundice or jaundice of obscure origin. The purpose of this study was to assess the diagnostic accuracy and safety of this procedure. TNC was performed by the technique described by Redeker et al. using the Chiba needle (JAMA 231:386, 1975). Obstructed ducts were successfully demonstrated in 100% of cases (29/29). Non-obstructed ducts were opacified in 12/21 (57%). Overall success was 82% (41/50). Two septic complications occurred. It is concluded that 1) TNC is a highly reliable, easy to perform and safe procedure in the evaluation of the jaundiced patient; 2) Accurate demonstration of the biliary anatomy by TNC provided important information which often in (10/50 = 20%) led to a change in diagnosis, avoidance of unnecessary procedures, and shortening of hospitalization; 3) Failure to visualize patients with non-dilated biliary ducts occurred with advanced chronic liver disease or fatty liver.

Alcohol can induce a wide spectrum of histological changes in the liver. Three morphologic patterns of alcoholic liver injury are now generally accepted, i.e. fatty change, alcoholic hepatitis and alcoholic cirrhosis, but a broad array of lesions has been added to this list in recent years. These damage patterns differ considerably in their significance as to indication and diagnostic power of liver biopsies. Liver biopsy is recommended in patients with clinically suspected alcoholic liver disease for diagnostic and prognostic reasons. Moreover, clinicians want to exclude nonalcoholic liver diseases that might otherwise be missed. Alcoholic hepatitis, which is associated with increased morbidity and mortality, has the highest degree of diagnostic specificity in biopsies, because its features are well-defined and are mimicked by a rather small group of other causes. When associated with perivenular and pericellular fibrosis, it may provide prognostic parameters. In contrast, fatty liver, which may be induced by alcohol as well as other etiologies, usually does not need liver biopsy, with some exceptions. It may lead to cholestasis severe enough to mimic obstructive jaundice, or may result in abnormal imaging studies suggesting metastases. Verification of histological findings may be important when these circumstances arise. Cirrhosis is easily verified in biopsies of appropriate quality; however, advanced cirrhosis is a morphologically nonspecific alteration, because cirrhotic tissue patterns converge irrespective of their cause. Liver biopsy may help to identify nonalcoholic liver disease in patients suspected of harboring alcoholic liver disease. In fact, up to 20% of biopsies may show other, potentially treatable disorders, thus extending the indication for liver biopsy in situations of complex clinical and laboratory patterns.

The amino acid composition of proteins from liver mitochondrial membranes has been studied in patients with normal liver, with biliary diseases and fatty liver, with obstructive jaundice or liver cirrhosis. A characteristic pattern of the amino acid composition in patients with normal liver has been found. In the mitochondrial membranes of patients with fatty liver tryptophan and lysine were decreased while [aspartic acid plus asparagine] and [glutamic acid plus glutamine] were increased compared to their counterpart in the normal liver. In patients with obstructive jaundice of short duration (less than two months) only a slight decrease in methionine content was found, while in the case of liver cirrhosis amino acid composition was markedly changed.

Insulin responses to oral glucose loads were studied in patients with obstructive jaundice and compared with those of other liver diseases (fatty liver, chronic hepatitis and liver cirrhosis), pancreatic diseases, and definite diabetes mellitus. Compared with their corresponding glucose intolerance, high insulin responses were characteristic in fatty liver, chronic hepatitis and liver cirrhosis, and insulin responses and insulinogenic index decreased in chronic hepatitis and liver cirrhosis as glucose intolerance progressed. In obstructive jaundice with the pancreatic ducts stenotic or obstructed, insulin responses were suppressed in comparison with their corresponding glucose intolerance, and also insulinogenic index were below 0.5 in most of the cases. However, in obstructive jaundice with the pancreatic ducts intact, high insulin responses were observed in almost half of the cases with insulinogenic index above 0.5, and insulin response and insulinogenic index decreased as glucose intolerance progressed. While most cases of fatty liver, chronic hepatitis and liver cirrhosis with insulinogenic index above 0.5 were distributed in non-diabetes zone in sigma BS-sigma IRI plane (Kosaka's), those with insulinogenic index below 0.5 were distributed in intermediate zone. Most cases with obstructive jaundice with pancreatic ducts stenotic or obstructed, had insulinogenic index below 0.5 and were distributed in diabetes zone. However, half of cases with obstructive jaundice with pancreatic ducts intact, had insulinogenic index above 0.5 and their distribution in non-diabetes zone, while the other half had insulinogenic index below 0.5 and their distribution in diabetes zone. Therefore, it may be concluded that insulin responses increase at the early stage of obstructive jaundice mainly under influence of liver dysfunction itself, but that insulin response is suppressed at later stage of obstructive jaundice as pancreatic islets are affected.

Serum angiotensin-converting enzyme activity was measured in various diseases of the liver. Activity increased in progressive order in patients with chronic persistent hepatitis, chronic aggressive hepatitis, and liver cirrhosis. Activity was increased also in patients with acute hepatitis. On the other hand, patients with fatty liver had normal angiotensin-converting enzyme activity and patients with extrahepatic obstructive jaundice showed subnormal activity. Although the mechanism for these enzymatic changes in diseases of the liver remains to be elucidated, serum angiotensin-converting enzyme determination may be useful in the diagnosis of diseases of the liver under certain conditions.

Computed tomographic (CT) evaluation of the bile ducts in the fatty liver can be difficult, since hepatic attenuation decreases with increased triglyceride content, and liver parenchyma may become isodense with bile. Forty-seven patients with fatty infiltration of the liver were retrospectively identified. In 7 of these patients, attenuation of liver and bile differed by less than 10 HU. In 2 patients, dilated intrahepatic ducts were invisible using CT, because bile was isodense with fatty liver parenchyma. Thus, the fatty liver presents a potential pitfall in CT evaluation of the bile ducts. Obstructive jaundice can be diagnosed in patients with fatty liver, if the extrahepatic ducts and peribiliary vascular plexus region are carefully scrutinized. For maximal accuracy, scans should be obtained both before and after administration of intravenous urographic contrast material.

Drug damage to the liver can be divided into two types: Type I damage is predictable, dose-dependent and appears in most patients treated. Type II lesions are not predictable, are not dose-dependent and occur in only a small percentage of patients. Clinically they can be differentiated into (1) a cytotoxic form (clinical picture: fatty liver, virus hepatitis), (2) a cholestatic form (clinical picture: obstructive jaundice) and (3) a mixed form. In the present study, liver damage due to the following drugs, as important examples of the different types of damage, are dealt with in greater detail: isoniazid (unpredictable damage of the cytotoxic type), methotrexate (predictable damage of the cytotoxic type) chlorpromazine (unpredictable damage of the cholestatic type) and finally estrogens or oral contraceptives (damage of the cholestatic type and other damage to the hepatobiliary system).
