title: Indications for laparoscopy before and after the introduction of ultrasonography.
abstract: We compared the outcome of laparoscopy performed from 1973 to 1974, prior to the introduction of routine ultrasound diagnostics, with that of examinations during the period 1980-1981 when ultrasound had become a well-established technique in the diagnosis of hepatic lesions. Our data reveal statistically significant changes in the use of laparoscopy in the diagnosis of cholestasis and tumors of the hepatic parenchyma. Laparoscopy now has fewer indications in the study of the jaundiced patient with suspected extrahepatic cholestasis which is easily identified at ultrasound. Given the high sensitivity and specificity of ultrasonography in detecting metastases, laparoscopy has become a secondary examination. However, there has been an increase in the use of laparoscopy to identify benign hepatic lesions, particularly hemangiomas.
