A short survey is given on description and evaluation of progress and developmental trend of laparoscopy. Important technical improvements are the cold light via the glass fibre light conductor, optics of high value, the colour photography with electronic flash-light, colour films and colour television, new accessory instruments and belongings. Now as ever hepatomegaly and splenomegaly, jaundice, ascites, portal hypertension, suspicion of cirrhosis and metastases are regarded as main indications. The laparoscopy deserves a greater consideration in unclear abdominal symptoms, in gynaecological diseases, for the proof of the affection of liver and spleen in lymphogranulomatosis, sarcoidosis, tuberculosis (with aimed liver biopsy). The endoscopic retrograde cholangiopancreatography in the differential diagnosis of the jaundice competes with the laparoscopy, but it is not able to supersede it. The laparoscopic judgment of the pancreas and the importance of visible changes of the fine structed. Among the contraindications of the laparoscopy the hiatal hernia has lost its significance.

An autopsy case of a 65-year-old male who died of hepatocellular carcinoma superimposed on liver cirrhosis complicated with systemic sarcoidosis is presented. No organ metastasis of hepatocellular carcinoma was found except for a minute tumor embolus in the left upper lobe of the lung. Involved organs by sarcoidosis were the lymph nodes, lungs, heart, liver and spleen, but its presence was not noticed before death. Its cardiac involvement coincide with his clinical symptom of exertional dyspnea and the ECG finding of A-V block.

Ninety patients with chronic diffuse liver disease were evaluated with free hepatic venography, wedge hepatic venography, hepatic vein pressure measurements, and liver biopsy. Free hepatic venograms were normal and minimally pruned in patients with hepatic sarcoidosis and fatty liver due to alcohol, and their biopsies showed little or no fibrosis. Pruning of hepatic vein branches on free hepatic venography correlated well with the corrected wedged hepatic vein pressure and with the degree of fibrosis in patients with alcoholic hepatitis, alcoholic cirrhosis, and postnecrotic cirrhosis. Free hepatic venography correlated better with hemodynamic measurements and fibrosis than did wedge hepatic venography. Free hepatic venography is a reliable predictor of the presence and degree of hepatic fibrosis and may be a useful alternative to liver biopsy in patients with clotting disorders.

Liver disease with inclusions of copper was recognized among 30 rural workers with "vineyard sprayer's lung." The pathological findings were varied: focal or diffuse swelling and proliferation of Kupffer cells; histiocytic and sarcoid-like granulomata; fibrosis of variable degree in the perisinusoidal, portal, and subcapsular areas, accompanied by atypical proliferation of the sinusoidal lining cells; micronodular cirrhosis; angiosarcoma of the liver; idiopathic portal hypertension. Abundant deposits of copper were revealed by histochemical techniques within hepatic and pulmonary lesions in these patients. The observations on the human and experimental material suggest an etiological relationship between exposure to copper sulfate and the lesions described. A morphological resemblance was noted between the "liver disease of vineyard sprayers" and the hepatic lesions reported in workers exposed to inorganic arsenic and to vinyl chloride. The identification of the inhaled foreign material within the liver lesions raises important etiological considerations.

Human plasma prekallikrein (Fletcher factor) clotting activity and antigen levels have been examined in various clinical conditions. Prekallikrein antigen was measured by a newly developed, specific, and sensitive radioimmunoassay. The assay had no demonstrable cross-reactivity with human urinary kallikrein nor, in the species tested, animal plasma prekallikrein. This assay was able to measure plasma kallikrein after its biological functions had been inactivated by plasma inhibitors. Normal human pooled plasma contained approximately 50 microgram/ml prekallikrein. Quantitative measurement of plasma prekallikrein was possible for concentrations as low as 0.3% of that of normal pooled plasma. A good correlation (correlation coefficient = 0.71) existed between titers of plasma prekallikrein measured by Fletcher factor clotting assays and radioimmunoassays among 40 normal subjects. Both prekallikrein clotting activity and antigen were significantly reduced in plasmas of patients with advanced hepatic cirrhosis or DIC. Prekallikrein activity and antigen were mildly decreased in plasmas or serums of patients with chronic renal failure and nephrotic syndrome but were normal in those of patients under treatment with warfarin or suffering from SLE, rheumatoid arthritis, sarcoidosis, or HANE. Human cord serum contained a lower titer of prekallikrein antigen than adult serum. Strenuous physical exercise did not significantly change plasma prekallikrein levels.

The leukotactic function of patients with sarcoidosis was studied. A defect was found in 19 of the 20 patients tested and was due to moderately elevated serum levels of the chemotactic factor inactivator. The chemotactic factor inactivator levels were not as high as those previously reported in patients with Hodgkin's disease or cirrhosis of the liver. The effect of the inactivator was irreversible and was directed toward all three of the chemotactic factors tested. The physicochemical characteristics of chemotactic factor inactivator in serum from sarcoid patients resembled in most respects the features of chemotactic factor inactivator in normal serum. As expected, the generation of chemotactic activity in some sarcoid serums by zymosan was impaired. The results of this study may relate to some of the reported defects in expression of immunity in sarcoid patients.

Fitzgerald factor (high molecular weight kininogen) is an agent in normal human plasma that corrects the impaired in vitro surface-mediated plasma reactions of blood coagulation, fibrinolysis, and kinin generation observed in Fitzgerald trait plasma. To assess the possible pathophysiologic role of Fitzgerald factor, its titer was measured by a functional clot-promoting assay. Mean +/- SD in 42 normal adults was 0.99+/-0.25 units/ml, one unit being the activity in 1 ml of normal pooled plasma. No difference in titer was noted between normal men and women, during pregnancy, or after physical exercise. Fitzgerald factor activity was significantly reduced in the plasmas of eight patients with advanced hepatic cirrhosis (0.40+/-0.09 units/ml) and of ten patients with disseminated intravascular coagulation (0.60+/-0.30 units/ml), but was normal in plasmas of patients with other congenital clotting factor deficiencies, nephrotic syndrome, rheumatoid arthritis, systemic lupus erythematosus, or sarcoidosis, or under treatment with warfarin. The plasmas of 21 mammalian species tested appeared to contain Fitzgerald factor activity, but those of two avian, two repitilian, and one amphibian species did not correct the coagulant defect in Fitzgerald trait plasmas.

Individual observers interpreted images in order to assess their accuracy and sources of error. Seventy-six liver images were presented to nine readers for interpretation. Readers of differing experience participated in the study: four radiology residents, three fellows in nuclear medicine, and two full-time nuclear medicine physicians. A higher incidence of false-positive reading was more common in inexperienced observers (11-50%) and the most correct readings were obtained by staff physicians (88% overall percentage accuracy). Heterogeneity in radionuclide uptake was the most frequently ill-defined nature was the most common false-positive finding in normal cases. Early stages of cirrhosis, mild hepatitis, and rare diseases such as hepatic sarcoidosis were difficult to detect. Skill of interpretation improved with experience, especially in judging heterogeneity of an ill-defined nature, and the rate of accurate readings was proportional to the level of training of the observer.

The development of the syndrome of chronic intrahepatic cholestasis in five young, black men who had systemic granulomatous disease and clinical features consistent with those of sarcoidosis is described. Clinical and biochemical aspects, similar to those of primary biliary cirrhosis, included pruritus, jaundice, hepatomegaly and striking elevations of serum levels of alkaline phosphatase and cholesterol. (One patient had skin xanthomas.) Mitochondrial antibodies were not found; and survival of the patients (7 to 18 years) exceeded the usual survival of patients with primary biliary cirrhosis. The histologic abnormalities included noncaseating granulomas, chronic intrahepatic cholestasis, increased copper in hepatocytes, progressive diminution in number of interiobular bile ducts, periportal fibrosis and the eventual development of a micronodular "biliary" cirrhosis. The histologic evolution of the disease suggests a slow, progressive destruction of the bile ducts by granulomas. Although the end stage of this syndrome resembles primary biliary cirrhosis, the characteristic nonsuppurative, destructive cholangitis of primary biliary cirrhosis was not present.

A 62-year-old woman presented with uveitis and abnormal chest X-ray (bilateral hilar adenopathy). Skin biopsy in 1983 had revealed non-caseating epithelioid cell granuloma consistent with sarcoidosis. Her serum biochemical investigations and exploratory laparoscopy suggested nodular liver cirrhosis, but biopsy was not performed. Both blood urea nitrogen (BUN) and serum creatinine values were within normal limits. She received prednisolone therapy of 15 mg daily initially, and later a maintenance dose of 5 mg daily. In 1985, she complained of skin itching and her laboratory data revealed severe renal insufficiency (BUN 97 mg/dl, serum creatinine 12.2 mg/dl) and hypercalcemia (corrected serum calcium level: 11.5 mg/dl). Prednisolone treatment (40 mg daily) resulted in a dramatic improvement of renal function as well as other clinical abnormalities due to sarcoidosis, without any significant changes in liver function. She died of cerebral infarction in 1989. Autopsy showed interstitial nephritis with tubular calcinosis and hyalinized glomeruli. It is postulated that hypercalcemia due to sarcoidosis contributed to the renal failure in this patient. This case suggests that renal damage due to sarcoidosis may be reversible with appropriate corticosteroid therapy.
