[Diagnostic value of cytological investigations in metastatic tumours of the liver: comparison of laparoscopy, histology, and cytology (author's transl)].

Fine needle aspiration biopsy is generally a harmless method if contraindications are considered and provides sufficient tissue for cytological evaluation. The diagnostic value is very high: in 27 cases of metastatic tumours of the liver diagnosed by laparoscopy the diagnosis was confirmed in 26 cases and revised in one case. In a control group of 200 patients with various diffuse liver diseases or morphologically normal findings no false positive results were found. In no case were post-biopsy haemorrhage or other complications observed. Needle biopsy and cytological evaluation should be used with an increased frequency when a malignant tumour of the liver is suspected clinically. After primary localization of suspicious areas by ultrasound or scanning the pick-up rate is high. Laparoscopy with precisely aimed fine needle biopsy is the method for verifying the diagnosis in cases with cytologically negative results which is up to 100% accurate.

[Controlled study of the therapeutic effect of B vitamins and an anabolic steroid in chronic hepatitis (author's transl)].

In 66 patients with chronic active hepatitis and chronic fatty liver hepatitis of predominantly alcoholic aetiology the effect of B vitamins and the anabolic steroid clostebol (Steranabol) was tested during an eight-week period, using 12-biochemical parameters of liver function, histological findings and the activity of 14 enzymes. In chronic active hepatitis there was no demonstrable difference in effect between the treated and untreated subjects. In those with chronic fatty liver hepatitis, the marked greater therapeutic effect among the untreated group during hospitalization is thought to have been due largely to an accompanying reduction of alcohol intake.

[In vivo dissolving of gall-stones: the effect of chenodeoxycholic acid. (author's transl)].

Chenodeoxycholic acid (CDCA) was administered for an average of 15 months to 14 patients with gall-stones. The gall-stones were radiolucent in all but one instance (solitary calcified stone). Stones dissolved completely after 12 and 15 months of therapy, respectively, in two patients, while in four the size of the stones diminished. No change occurred in the remaining patients. In five patients multiple stones dissolved, while in one a radiolucent solitary stone dissolved. In one patient, with a negative cholecystogram for a time before being treated with CDCA, the gall-bladder perforated while on treatment. CDCA was well tolerated by all patients: upper abdominal discomfort disappeared during CDCA treatment in two patients and improved in nine. Only side-effect was occasional mild diarrhoea in five patients. Bile was analysed in seven patients, supersaturation with cholesterol being found in five. Biliary lipid composition became normal during CDCA treatment in these five patients. Serum triglyceride levels fell during CDCA administration in ten of eleven patients in which serum measurements were made; the greatest fall occurred in the five patients with hypertriglyceridaemia. The fall in triglyceride levels was associated with a diminution of the pre-beta-lipo-protein fraction and the chylomicron fraction. No significant change occurred in serum cholesterol levels.

[Comparison of laparoscopic and scintigraphic findings in chronic hep-titis, liver cirrhosis and liver tumours (author's transl)].

Results of laparoscopy and scintigraphy were compared and contrasted with ultimate clinical diagnosis in 94 patients with chronic hepatitis or liver cirrhosis and 38 with liver tumours. The findings agreed in 77 cases of chronic hepatitis and cirrhosis and 33 of liver tumour. In the remainder either laparoscopy or scintigraphy gave the wrong results. In one case each of cirrhosis and liver metluded that (1) laparoscopy and scintigraphy are methods complementing but not replacing other clinical tests; (2) if diffuse liver disease is suspected clinically the diagnosis can essentially be done only by laparoscopy and selective biopsy or blind liver biopsy but not scintigraphy; (o) if a circumscribed condition is suspected, scintigraphy is among the most important screening tests, but cannot replace laparoscopy, biopsy or angiography for confirming the diagnosis; (4) liver scan is an important method, of little stress to the patient, in following the progress of chronic hepatitis and liver cirrhosis, additional to clinical examination, enzyme tests, laparoscopy and histology.

Studies of liver function and structure in patients with gallstones before and during treatment with chenodeoxycholic acid.

Twelve patients with gallstones were treated with chenodeoxycholic acid (CDCA) for 3 to 22 months. Liver function and structure were studied before and during treatment. No signs of hepatotoxicity were observed. Activities of several enzymes, including transaminases, GLDH, and gamma-GT were frequently abnormal in this group of patients. But there was no statistical difference between treatment and pre-treatment levels. Serum bilirubin and protein electrophoresis remained normal throughout the study. The BSP retention test was not significantly altered by CDCA treatment. Light microscopic examination in 8 patients revealed no changes of liver structure during 3 to 19 months of CDCA administration except, however, for a decrease of fatty changes in 3 patients. The ultrastructure of liver cells was found to be normal in 5 patients, in whom electron microscopy was done as well.
