Alterations of bile salt metabolism have been shown in numerous diseases. Liver damage results in elevated serum bile salt concentrations which may be useful as a sensitive index of hepatocellular disease. Changes in the relative proportions of the individual bile salts in serum occur with cholestasis. Urinary excretion of bile salts, largely in the form of sulphates, increases as a compensatory mechanism. Ileal disease or resection causes bile salt melabsorption. The increase in colonic bile salts produces a watery diarrhoea while the decrease in duodenal levels may cause steatorrhoea. Cholelithiasis may result from alteration in the relative proportions of cholesterol, lecithin and bile salts in bile. The mechanism apparently differs in various conditions predisposing to gallstone formation. A primary alteration of bile salt metabolism has been postulated in several other conditions. Considerable interest centres on the importance of metabolites of bile salts in the pathogenesis of colonic carcinoma. Chenodeoxycholic acid is a successful though costly treatment for selected patients with cholesterol gallstones. Bile salt binding agents, such as cholestyramine, are extremely useful especially in the control of pruritus in patients with cholestasis.

Clinically apparent pancreatic disease due to sarcoidosis has not been described in typical sarcoid patients. A few cases have been described at exploratory laparotomy and pancreatic involvement in autopsied cases is more common than generally appreciated. We report a patient not previously known to have sarcoidosis whose presentation with pruritus, eosinophilia and cholestatic serum chemistry suggested a reaction to phenothiazines. The correct diagnosis was made during surgery for an asymptomatic gallstone. No other evidence of pancreatic disease has become apparent during follow-ups of two years.

Even in the absence of gallstones, the hepatobiliary system should be suspected as a possible cause of pruritus in a patient with sickle cell disease. A case is presented in which a sickle cell patient had severe pruritus relieved by cholestyramine therapy.

The clinical and laboratory findings in 32 patients with erythropoietic protoporphyria as well as a review of the pertinent literature on this relatively recently described form of porphyria are presented. The disease is thought to be transmitted in an autosomal dominant fashion with variable penetrance and was characterized in these 32 patients by the onset in childhood of burning (97 per cent) and itching (88 per cent) of the skin on exposure to sunlight. This was accompanied by edema (49 per cent) and erythema (69 per cent) of the exposed areas. Vesicles, petechiae and residual scarring occurred less frequently. Associated abnormalities included cholelithiasis (12 per cent), anemia (27 per cent) and abnormal liver function studies (4 per cent). Reports of associated liver disease including nine cases of fatal hepatic failure, are reviewed. Current methods of diagnosis as well as theories of pathophysiology of the disease are presented. Nineteen of 23 of these patients recently treated with beta-carotene responded with significant increase in their tolerance to sun exposure.

An 82-year-old man was admitted because of painless jaundice and pruritus. Multiple small gallstones were seen on ultrasonography. Hepatic needle biopsy revealed bile stasis, intrahepatic bile ducts proliferation and inflammatory infiltration of the portal spaces. As the jaundice deepened, cholecystectomy was performed and a gallbladder full of small calculi was removed. Wedge biopsy of the liver led to the diagnosis of primary biliary cirrhosis (PBC). Colchicine was started and since then his condition has improved and become stable. PBC in an old man is very uncommon. The combination with gallbladder stones imposed special diagnostic and therapeutic problems. Although gallbladder stones are more common in PBC than in the general population, the combination of the 2 clinical entities is not sufficiently emphasized in the literature.

Two siblings (a 2-year-old female and 11-month-old male) with similar onset of obstructive jaundice and clinical manifestations from early infancy are described. The jaundice fluctuated but never completely disappeared. Abnormal amounts of cholate, chenodeoxycholate and ursodeoxycholate were found in serum bile acid fractions. Pruritus, hyperbilirubinemia of predominantly the conjugated fraction and bilirubinuria were increased by repeated respiratory infections. Ultrasonography showed several highly echogenic shadows in the gallbladder in both cases, and gallstones were found at surgery. Operative cholangiography showed an anomalous arrangement of pancreaticobiliary ductal system in both cases. The pedigree showed five relatives (including the father) on the paternal side had liver disease, and an autosomal recessive inheritance was suggested. The association of familial intrahepatic cholestasis with a large amount of serum bile acids (which seem to be due to abnormal bile acid metabolism), cholelithiasis and anomalous arrangement of the pancreaticobiliary ductal system is proposed as a new hepatobiliary syndrome.

The analysis is presented of 67 patients with primary biliary cirrhosis treated in the years 1971-1988. The group consisted of 60 women (89.5%) and seven men (10.5%). Presenting symptoms were mostly itching (66%) and jaundice (12%). The time between the onset of the first symptoms and the diagnosis was three years, on the average. Autoantibodies to mitochondria were present in 86% of patients. In 27% of cases markers of HB virus infection were found. Cholelithiasis was present in 19 patients (28%). Primary biliary cirrhosis was diagnosed with delay. Third degree of histological changes was observed in 38.8% of cases and in 18% of patients it was already fourth degree. Eighteen patients (27%) died after six years, on the average, from the onset of symptoms. The direct causes of death were, most frequently, liver failure and haemorrhage from oesophageal varices.

In several overseas centres endoscopic biliary drainage is now a standard procedure in the initial or definitive management of biliary tract obstruction. We report the first nine patients in whom this procedure was carried out in our unit. Four patients presented with acute cholangitis due to cholelithiasis. Urgent endoscopic biliary drainage improved the general condition in three patients prior to subsequent elective surgery. In one other patient with huge common bile duct calculi a biliary stent prevented recurrent episodes of cholangitis. Endoscopic endoprostheses were used in three patients with malignant biliary tract obstruction. Two had terminal metastatic disease and endoscopic drainage provided adequate palliation of jaundice and pruritus in one. Endoprosthesis blockage necessitated percutaneous drainage in the other patient. The third patient with carcinoma of the head of the pancreas was improved by endoscopic drainage prior to an open surgical bypass procedure. Another patient with obstructive jaundice due to terminal gall bladder carcinoma experienced relief of jaundice and pruritus following endoscopic insertion of a nasobiliary drain. We anticipate that endoscopic biliary drainage will become increasingly used in Singapore.

The occurrence of hepatobiliary disease with or without jaundice during pregnancy provides both the hepatologist and obstetrician with an interesting and urgent diagnostic challenge. Advances in our understanding and management of liver disorders unique to pregnancy and hepatobiliary disease in general have resulted in a significant improvement in the outcome for both mother and fetus. Certain disorders such as acute fatty liver of pregnancy and hepatic haemorrhage associated with toxaemia should be considered medical emergencies and delay in diagnosis of these conditions will probably adversely affect maternal and fetal outcome. A careful clinical history, physical examination, appropriate laboratory tests and radiological investigations should allow a diagnosis within 24-48 hours of presentation. Liver biopsy is rarely required. A careful history may provide important information. Does the patient have pre-existent liver disease? Has there been contact with hepatitis, intravenous drug abuse or any other factor predisposing to acute viral hepatitis? Does the patient have a family history of pruritus and/or jaundice to suggest intrahepatic cholestasis of pregnancy? Is the patient's alcohol consumption excessive? Has the patient received any hepatotoxic medications? Has there been abdominal pain and/or fever to suggest gallstones, hepatic bleeding or acute fatty liver of pregnancy? Laboratory investigations may give valuable diagnostic clues. Marked aminotransferase elevation would suggest acute viral or 'ischaemic' hepatitis. Haematological features of microangiopathic haemolysis would point towards toxaemia or AFLP. Hepatitis A and B serological tests may be helpful in viral liver disease. Radiological investigations may be indicated depending on the clinical context. Abdominal ultrasonography may be useful in the diagnosis of gallstones, biliary obstruction, liver tumours or intrahepatic bleeding. Fatty infiltration of the liver may be diagnosed by ultrasonography but computed tomography (CT) of the abdomen is probably more reliable for a diagnosis of acute fatty liver of pregnancy as it allows measurement of liver density which is typically reduced by fatty infiltration. CT scanning is also probably more valuable than ultrasound in assessing the extent of capsular rupture and haemorrhage into the liver and peritoneal cavity.

Benign recurrent intrahepatic cholestasis is characterized by attacks of cholestasis. The purpose of our study of 26 patients was to emphasize some features uncommonly or never reported in this disease: (a) in each patient, the attacks of cholestasis were stereotypic; (b) attacks of cholestasis were not associated with pruritus in 15% of our patients; (c) the occurrence of attacks of cholestasis during pregnancy or oral contraceptive use might be a fortuitous coincidence; (d) gallstones were found in several patients with benign recurrent intrahepatic cholestasis and might be present earlier than in the general population; (e) in some of our patients, during attacks of cholestasis, serum transaminases were very high, exceeding 15 times the upper limit of normal; (f) mild portal inflammatory infiltration was found in one third of our patients; (g) no treatment shortened the duration of cholestasis, and in a few patients, plasmapheresis seemed to diminish jaundice and improve biochemical disorders.
