The case histories of 1200 patients admitted to our hospital over a 20 month period were reviewed to determine the degree, frequency and cause of dissociated
cholestasis
as a biological syndrome. Patients were divided into two groups: group I with 80 cases, included all patients whose gamma-GT levels were more than 30 mU/ml and serum-bilirubin less than 1.2 mg/ml, with alkaline phosphatase levels between 90-180 mU/ml. Group II included those with alkaline phosphatase levels higher than 180 mU/ml (57 cases). All over incidence of dissociated
cholestasis
was 13.82%. Main causes in group I were infectious diseases, mainly pneumonias and urinary infections and congestive cardiac failure. In group II, neoplasias such as Hodgkin's disease and epithelial
metastases
and obstructions of the biliary tract such as vesicular or choledocal litiasis were the main causes. Transaminase levels underwent variable increases according to the different entities, without there being any difference between the two groups. The physiopathology as well as the anatomopathological aspects which could originate the syndrome are discussed.

The number, intracellular distribution, and staining characteristics of human hepatocellular peroxisomes that had been made visible by cytochemical staining for catalase were evaluated in biopsies from 75 patients with hepatic, inflammatory, or malignant disease and ten normal individuals. Intensity of staining was found to be proportional to enzymatic activity by microspectrophotometry. Scanning transmission electron microscopy (STEM) image analysis demonstrated an inverse relationship between peroxisomal size and contrast. Peroxisomes were more abundant, and often concentrated in a perinuclear configuration in cholestatic and cirrhotic livers. Decreased peroxisomal staining was common in
cholestasis
, cirrhosis, hepatitis, and in almost all patients with malignancies, both with and without hepatic
metastases
.

Records of 19 autopsied patients with metastatic carcinoma were studied to elucidate the contribution to the elevation of antemortem plasma carcinoembryonic antigen (CEA) levels (range, 5.9--136,000 ng/ml) of 1) liver pathology and dysfunction, 2) tumor morphology and CEA content, and 3) tumor spread and location. Liver function tests and plasma CEA recorded within 8 weeks of death, autopsy records of tumor spread, liver weight (as an index of liver tumor mass), and histologic sections were reviewed. Tissue CEA was demonstrated in 15 patients by an immunoperoxidase method.
Cholestasis
was seen in histologic sections of tissue from 8 of 10 patients, and elevated bilirubin was seen in 7 of 10 patients with hepatic
metastases
and CEA levels greater than 1,000 ng/ml In contrast, histologically observed
cholestasis
and elevated bilirubin were seen in only 1 of 8 patients with CEA less than 500 ng/ml. A significant correlation was found between the plasma CEA level and histologically observed
cholestasis
(P less than 0.01). Serum bilirubin also correlated significantly (P less than 0.01), but alkaline phosphatase did not. Liver weight (tumor mass) showed a positive correlation with
cholestasis
(P less than 0.01) but not with circulating CEA. Markedly elevated plasma CEA levels (greater than 1,000 ng/ml) seen preterminally may partially reflect impaired excretion of CEA by the hepatobiliary system rather than, or in addition to, preterminal increase in CEA-producing tumor.

Jaundice associated with primary carcinoma of the lung was identified in 19 patients from 1973-1978. Eight of these patients had demonstration of extrahepatic
bile duct obstruction
(EHBDO). The most frequent histologic type of lung tumor was undifferentiated, occurring in six of the eight patients with proved EHBDO. The EHBDO resulted from metastatic involvement in peripancreatic, periportal, and peribiliary lymph nodes.
Metastasis
to the common bile duct was rare. However,
metastases
to the head of the pancreas were a frequent event, being found in six of the eight patients with EHBDO. Discussion of diagnosis and recommendations for treatment are included.

The medical records of 66 women treated with metenolone for metastasized breast carcinomas were analysed. In 26 patients a remission developed with a mean duration of 8.2 (3-29) months. Patients whose treatment started in the first year after the menopause as well as patients with a beneficial effect of a therapeutic ovariectomy in the past were more often improved by metenolone than average. Metenolone had a better effect against osseous
metastases
than against visceral
metastases
. In most cases the treatment was well tolerated. In four patients, however, the treatment had to be interrupted because of
cholestasis
, pulmonary embolism and hypercalcaemia.

Twenty-seven patients underwent percutaneous antegrade biliary drainage for obstructive jaundice. The serum bilirubin levels was elevated in all patients. Generalized pruritus was a major complaint. Twenty of the patients had had a laparotomy for malignant disease. Of the 24 patients in whom this method of drainage was successful, the obstructing lesion was found at the porta hepatis in 12 and in the extrahepatic bile ducts in 12.
Metastatic disease
was the commonest cause of obstruction. Following drainage the serum bilirubin level fell from a mean of 21.4 mg/dl (366 mumol/l) to a mean of 4.1 mg/dl (70.1 mumol/l) within a week. Pruritus was relieved. The major complications were transient cholangitis in five patients and inadvertent dislodgement of the catheter in four. In three of these patients another catheter was reinserted with ease. There was no peritonitis or uncontrolled bleeding. Twenty-one patients were able to leave hospital. Their mean survival time was 7.3 months. A multiperforated catheter manipulated through the obstruction has the advantage of permitting bile flow into the duodenum (antegrade) in contrast to external drainage (retrograde) by T- or U-tubes. Although the mean survival time with this method is similar to that with insertion of drainage tubes at the time of laparotomy, morbidity and mortality are reduced; this is important in view of the poor prognosis of
bile duct obstruction
due to malignant disease.

Differentiating between the hepatocellular "internal" and the "surgical" or "endoscopic"
cholestasis
syndrome has become a domain of sonography. There is a 92 to 99% success rate, due to the possibility of diagnosing by means of sonography dilations of the gall bladder, the extrahepatic biliary tract and the intrahepatic bile ducts, as well as numerous diseases of the hepatobiliary system and of the pancreas. Congested intra- and extrahepatic bile ducts indicate the presence of a deep-seated distal obstruction, such s a prepapillary concrement, an inflammatory or malignant papillary stenosis or of a process in the area of the head of the pancreas. If the intrahepatic bile ducts alone are dilated the obstructive process has to be assumed near the portal fissure of the liver. Frequent causes are directly demonstrable tumors or
metastases
on the hilum or high-lying concrements. By using sonography, the level of obstruction can be determined correctly in about 90% of cases, while the cause of obstruction can be diagnosed in about 60 to 70%. In most cases intrahepatic cholestase can only be demonstrated indirectly through the absence of a bile duct dilation. Characteristic diffuse changes in the liver (e.g. fatty liver, cirrhosis, cardiac liver) or intrahepatic space claims-may be in combination with an ultrasound-directed puncture-may support or confirm the diagnosis.

Twenty-one patients undergoing stent placement for extra-hepatic biliary obstruction by
metastatic disease
were reviewed. Primary tumours (colorectal 8, stomach 4, breast 2, ovary 2, others 5) had been diagnosed 13 months (median) before presentation with
bile duct obstruction
, which was at the porta hepatis or common hepatic duct in 14 patients and in the common bile duct in seven. Endoscopic stent placement was achieved in 14 out of 20 patients in whom it was attempted. A percutaneous trans-hepatic procedure was necessary in five patients. Two patients could not be stented. Median survival was 5 months (range 1 month to 6 years) in patients stented successfully but only 1 month (2 weeks to 3 months) in unsuccessful cases (P < 0.01). Nine patients survived more than 4 months. Patients with proximal obstruction fared less well than those with distal obstruction; they required more procedures and survived for shorter periods (median 1 month versus 5 months, P < 0.05). Worthwhile palliation is afforded to almost half these patients by endoscopic stent placement and individual patients may achieve prolonged, symptom-free survival.

Cholestatic jaundice is the result of a malignancy of the bile duct itself, of the gallbladder, of the ampulla or (as in most cases) of the pancreas. Patients without evidence of
metastases
or other signs of advanced cancer (e.g. ascites) are candidates for explorative laparotomy. In the vast majority of cases resection of a tumor is not feasible and the surgeon is faced with the objective of providing palliation. To date there exists not only one palliative procedure, and the surgeon has to take into account the following: In patients with pancreatic cancer palliation can be given with biliary bypass with or without gastroenterostomy. This carries an operative mortality of almost 20% and means a survival of only 5-6 months. Nonsurgical procedures as transpapillary stenting play an increasing role in the management of patients with obstructive jaundice due to pancreatic cancer. In some cases however resectable tumors perhaps will be overlooked. The results of controlled studies comparing endoscopic stenting and surgical bypass are encouraging for stenting techniques (lower morbidity and mortality (< 10%), technical success rates exceeding 90%). The availability of different palliative treatment modalities for carcinoma of the bile ducts suggests that no approach is definitely superior. Operative biliary-enteric anastomosis gives a tolerable operative mortality rate in younger patients, less morbidity, than external biliary drainage by better quality of life of the patients. In retrograde placement of prosthetic stents, in patients with high
bile duct obstruction
difficulties are frequently. In such cases the percutaneous drainage should be reserved for endoscopic failures, in cases the endoscopic and percutaneous approaches can be combined in the 'rendezvous' procedure. In recent years several reports have advocated extensive surgery for biliary neoplasms. Preoperative staging of these patients remains an issue as none of the commonly modalities are accurate in predicting resectability.

Cryotherapy is the in situ destruction of abnormal tissue using subzero temperatures (Fig. 1). Recent studies have demonstrated the technical feasibility, safety, and effectiveness of hepatic cryotherapy in the treatment of liver tumors [1, 2]. Such treatment can be precisely focused on the tumor, thereby preserving surrounding normal tissue. In addition, because major vessels with flowing blood are protected from cryoablation, tumors adjacent to these vessels can be treated without sacrificing vasculature. Hepatic cryoablation is therefore particularly suitable for patients who do not qualify for surgical resection because of multiple
metastases
involving both lobes of the liver, or because of lesions close to major blood vessels. After the procedure, CT during arterioportography is of little value in distinguishing cryolesion from malignant tumor (Fig. 2), and CT with IV contrast enhancement is recommended for follow-up. It is important to distinguish CT findings of successful and unsuccessful treatment, treatment complications such as abscess and
cholestasis
, and recurrent tumor. The purpose of this essay is to illustrate the findings on CT with IV contrast enhancement in various situations, emphasizing features that are useful in making accurate differential diagnosis.
