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.

Three patterns of hepatocyte injury in man, direct, immunological, and cholestatic, are described. The characteristics of the direct pattern are predominantly mitochondrial damage, central (zone 3) necrosis, and, usually, fatty change. It can be subdivided into the alcohol type (also seen with obesity, in diabetes, as a reaction to perhexiline, in Wilson's disease, and in Indian childhood cirrhosis) and the Reye's syndrome type (also seen with tetracycline toxicity, fatty liver of pregnancy, and cytotoxic drugs). Reactive drug metabolites, metal poisoning, and anoxia are also associated with the direct pattern of hepatocyte injury. The immunological pattern is characterised by damage to cell membranes with piecemeal necrosis of periportal (zone 1) hepatocytes and mononuclear-cell infiltration. Examples include chronic active hepatitis, primary biliary cirrhosis, and drug reactions such as those to halothane. In the cholestatic pattern there is disturbance of the bile-secretory mechanism with retention of bile within the hepatocytes. Cholestatic liver injury may be intrahepatic, as in sex-hormone cholestasis, or extrahepatic, as in choledocholithiasis or carcinoma of the bile ducts. Identification of the type of hepatocyte injury is valuable in diagnosis, in assessing prognosis, and in selecting treatment.

In a retrospective study of 1101 patients (302 men, 799 women; mean age 56,7 [19-88] years) with symptomatic cholelithiasis who had undergone elective cholecystectomy and intraoperative liver biopsy, histological examination revealed inflammatory changes in the gallbladder in 96.7%, chronic fibrotic cholecystitis in 94.5% and a severe form of cholecystitis in 8.8%. Clinically relevant changes in the liver parenchyma were present in 27.9%, most frequently intrahepatic cholangitis (21.8%). The latter was significantly more common in choledocholithiasis than in isolated cholecystolithiasis. 27 patients had signs of severe liver disease, namely viral hepatitis, cirrhosis or fatty liver. Since the gall-bladder in cholelithiasis is almost always inflamed, cholecystectomy is the treatment of choice. Not uncommonly liver biopsy will reveal clinically relevant changes in the liver parenchyma. This will be useful information, especially in the management of symptoms which persist postoperatively.

Hepato-biliary disorders are rare complications of pregnancy, but they may be severe, with high fetal and maternal morbidity and mortality. Imaging is, therefore, essential in the rapid diagnosis of some of these conditions so that appropriate, life-saving treatment can be administered. This pictorial essay illustrates the multimodality imaging features of pregnancy-induced hepato-biliary disorders, such as acute fatty liver of pregnancy, preeclamsia and eclampsia, and HELLP syndrome, as well as those conditions which occur in pregnancy but are not unique to it, such as viral hepatitis, Budd-Chiari syndrome, focal hepatic lesions, biliary sludge, cholecystolithiasis, and choledocholithiasis.
