Major biliary tract obstruction caused by tumour invasion is a rare manifestation of hepatocellular carcinoma. The authors had the opportunity to diagnose and treat five such cases, three of whom had features of acute cholangitis. The prevalence of both hepatocellular carcinoma and recurrent pyogenic cholangitis is high in patients from the Far East. The former may first present under the guise of the latter. Gastroenterologists and surgeons should be aware of hepatocellular carcinoma when managing these patients who present with obstructive jaundice, gross hepatomegaly and cholangitis.

Duodenofiberscopy with endoscopic retrograde cholangiopancreatography (ERCP) was performed in 102 patients with obstructive jaundice. Peritoneoscopy and peritoneoscopic cholecystocholangiography were done in patients whose ERCP was inconclusive. The causes of obstructive jaundice were carcinoma of the pancreas in 14 cases, carcinoma of the papilla of Vater in 12 cases, choledocholithiasis in 37 cases, carcinoma of the common bile duct in seven cases, hepatocellular carcinoma (HCC) in seven cases, intrahepatic cholestasis in three cases and miscellaneous causes in eight cases. No final diagnosis was made in 14 patients. The duodenofiberscopic examination with biopsy revealed the cause of obstructive jaundice directly in eight cases, when carcinoma of the pancreas or papilla of Vater extended to the duodenal mucosal surface. In 34 of the 37 patients with choledocholithiasis, ERCP alone was successful in making the diagnosis. Percutaneous transhepatic cholangiography and ERCP were used together to reach a diagnosis in the remaining three patients. We propose a classification for HCC on ERCP which may be useful for the study of icteric type HCC.

From December 1964 to November 1989, 71 children from 3 to 17 years of age with the eventual diagnosis of hepatocellular carcinoma (HCC) presented at the National Taiwan University Hospital (Taipei, Taiwan, Republic of China). Forty-three of them had pathologic proof, whereas 28 were diagnosed on a clinical and laboratory basis. A male predominance (M:F = 3.2:1) was noticed. Most patients presented in a late, advanced stage. Abdominal pain and abdominal mass were the major symptoms and signs, followed by anorexia, fever, and internal bleeding. Hydrocele, purpura, and obstructive jaundice were rare presenting symptoms. Hepatosplenomegaly, superficial venous engorgement, and ascites were the main physical signs. The prognosis for such children with HCC was very poor. Only 10% of the patients survived longer than 1 year after the onset of the initial symptom. Among 49 patients who could be followed, only two had long-term survival of over 5 years. One patient had a small HCC with internal bleeding, whereas the other had a large HCC with abdominal distention. Both received surgical resection, and a resection was repeated for tumor recurrence in the patient with the large mass. The resectability of these 71 patients was low (9.8%). Resectability and nonicterus seemed to be the factors indicating favourable prognosis. Observation indicated that the prognosis for children with symptomatic HCC is grave but surgical resection, whenever possible, should be carried out.

One hundred and sixty-eight laparoscopies, performed for various indications between 1985 and 1989, were studied retrospectively and the findings and experiences are reported. The most frequent diagnoses were hepatocellular carcinoma (20%) and liver cirrhosis (18%). Correlation of macroscopic and histopathological diagnosis was satisfactory in hepatocellular carcinoma (74%) and poor in liver cirrhosis (38%). Laparoscopy was judged diagnostic in 45%, diagnostically helpful in 20% and non-contributory in 35% of all cases. The highest yield was obtained in hepatocellular carcinoma and liver cirrhosis, the poorest results in obstructive jaundice. It is concluded that for optimum diagnostic outcome the indication for laparoscopy should be strict and that it should be practised only in those centres where experienced clinicians and competent histopathologists are available.

A 41-year-old woman was admitted to hospital with obstructive jaundice. Computed tomography showed a large mass in the right hepatic lobe and marked dilatation of the biliary tree in the left lateral segment of the liver. Angiography showed evidence of neovascularity. Percutaneous transhepatic cholangiography revealed complete obstruction of the common bile duct just below the bifurcation. The serum level of alpha-fetoprotein on admission was 1,080,000 ng/ml. These findings suggested to us a primary hepatocellular carcinoma invading the intrahepatic bile duct. Extended right lobectomy and hepaticojejunostomy for bile drainage was carried out. The patient is doing well 3 years after surgery. Hepatocellular carcinoma (HCC) invading to the portal vein is not so rare, but invasion into the bile duct is much less common. In 1947, Mallory described a single case of HCC invading the gallbladder and obstructing extrahepatic bile ducts. In 1975, Lin termed this HCC "Icteric type hepatoma". The incidence of such HCC in Japan was reported to be 1.9-9%. Obstructive jaundice is a clinical manifestation of the terminal stage in HCC. We describe here our treatment of a woman with HCC invading the common bile duct. Right extended lobectomy and reconstruction of hepaticojejunostomy were effective.

Between July 1973 and September 1990, 160 patients with hepatocellular carcinoma underwent hepatic resection at Keio University Hospital. Hepatic resection was carried out for patients with advanced diseases as well as recurrence. The patients with advanced disease consisted of 5 patients with obstructive jaundice, 6 with tumor thrombi in the portal trunk, one with tumor thrombus in hepatic vein, inferior vena cava and right atrium, 8 with satellite nodules in both lobes. Nine (45%) of these patients survived more than 2 years. Seven patients underwent removal of recurrent tumors: 4 in the remnant liver, one each at the left adrenal gland, lung and chest wall. Two patients lived longer than 2 years with relief of pain.

The serum activity of alcohol dehydrogenase was determined in healthy controls and in patients with liver diseases. The mean activity in hepatoma (6.4 +/- 1.0U/L) was significantly higher (P less than 0.05) than the mean values in liver cirrhosis (2.7 +/- 0.5U/L); hepatitis (4.3 +/- 1.0U/L), obstructive jaundice (2.9 +/- 0.5U/L) and healthy controls (0.7 +/- 0.1U/L). Alcohol dehydrogenase purified by CM-cellulose chromatography from the sera of patients with hepatoma had a higher affinity for butanol long chain saturated and unsaturated alcohols than the purified enzyme from healthy controls. Similarly, hepatoma alcohol dehydrogenase oxidized ethanol very poorly (KM = 154 microM) when compared with that from healthy controls (KM = 40.2 microM). Hepatoma alcohol dehydrogenase was inhibited by pyrazole while those of other liver diseases and the healthy controls were not. These properties of serum alcohol dehydrogenase may prove useful in the early diagnosis of hepatoma since biochemical changes occur before morphological changes in the development of cancer.

Serum Mn-superoxide dismutase (Mn-SOD) was determined in patients with various liver diseases including 31 patients with primary biliary cirrhosis (PBC), 46 with hepatocellular carcinoma (HCC), 17 with liver cirrhosis (LC), 23 with chronic hepatitis (CH) and 12 patients with obstructive jaundice with an enzyme-linked immunosorbent assay using a specific monoclonal antibody. The serum level in patients with PBC (407 +/- 35 ng/ml, mean +/- SEM; n = 31) was significantly increased (p less than 0.01) compared with those of other liver diseases. Mn-SOD level did not correlate with total bilirubin level, gamma-glutamyl transpeptidase activity, alkaline phosphatase activity, alanine aminotransferase activity, IgM, or with ceruloplasmin level in the sera of the patients. When the patients with PBC were histologically subdivided into four groups according to Scheuer's classification (Scheuer PJ. Primary biliary cirrhosis. In: Scheuer PJ, ed. Liver biopsy interpretation. 3rd ed. London: Bailliere Tindall, 1980:47-56), a high level of serum Mn-SOD was noticed in the early stage as well as in the advanced stage of the disease. Immunoblot analysis confirmed the reactivity and specificity of the monoclonal antibody to the enzyme protein in the patients' sera. Immunostaining of a liver biopsy specimen from the patients with PBC revealed increased expression of the enzyme protein in damaged epithelial cells of interlobular bile ducts, bile ductules, and degenerated hepatocytes. These data suggested that free radicals including superoxide anion are possibly involved in the pathogenesis of the disease and Mn-SOD may play some role in a protection against the superoxide anion.

Des-gamma-carboxy prothrombin (DCP), a protein induced by vitamin K absence or antagonist-II (PIVKA-II) was measured in the plasma of patients with primary hepatocellular carcinoma and those with various other hepatobiliary and pancreatic diseases. DCP levels were determined by enzyme immunoassay (E-1023), using an anti-DCP monoclonal antibody. Forty-two of the 91 patients (46.2%) with hepatocellular carcinoma had abnormally elevated levels of DCP, whereas only one of the 24 patients with hepatic cirrhosis showed a slight increase. An increase was also observed in some patients with obstructive jaundice. There was no correlation between plasma levels of DCP and those of serum alpha-fetoprotein (AFP). In most patients with hepatocellular carcinoma, plasma DCP levels normalized after curative surgical resection. Plasma DCP levels were not related to the plasma concentration of vitamin K in the patients with hepatocellular carcinoma. Plasma DCP determination may be useful in the diagnosis and postoperative monitoring of the response of hepatocellular carcinoma.

Percutaneous stenting for malignant biliary stenosis is quite beneficial to patients with unresectable or recurrent disease, tremendously improving the quality of their lives. Percutaneous transhepatic biliary drainage (PTBD) was attempted in 92 patients with obstructive jaundice during the period between January 1986 and July 1989. Implantation of an endoprosthesis was performed in 14 cases (15.2%) and succeeded in 12 (85.7%). When a guide wire could not be passed distally across the stricture site, percutaneous transhepatic cholangioscopy (PTCS) through the dilated PTBD fistula was carried out to enable its passage. PTCS is also valuable in the preoperative diagnosis of obstructive jaundice. The patients who are not candidates for surgery are suitable for this procedure. A Miller double-mushroom stent is used as the endoprosthesis in the majority of cases. One patient with recurrent hepatoma has lived at home with this stent for greater than 3 years due to repeated transarterial embolization and chemotherapy and does not need to wash or change the stent.
