title: Ultrasonography versus laparoscopy in the diagnosis of hepatic tumors.
abstract: 129 patients, with suspected primary or secondary benign or malignant liver neoplasm after clinical, biochemical and/or instrumental investigation underwent liver ultrasound and laparoscopy. Echographic findings were compared with laparoscopy when liver neoplasms were detected by the latter. When laparoscopy was negative, to evaluate the diagnostic accuracy of the two methods employed, the following variously associated parameters were analysed: clinical follow-up, liver biochemistry, computed tomography, liver selective arteriography and explorative laparotomy. In the 129 patients examined, echography showed 86.7% diagnostic accuracy and laparoscopy 89.4%. The association of the two methods led to a diagnosis of hepatic lesion in 98.4% with no further diagnostic investigations. The two procedures can be considered complementary to such an extent that, in case of suspected primary or secondary liver neoplasm, the association of ultrasound and laparoscopy represents a quick and ultimate diagnostic approach. Furthermore, the association of these two procedures seems the least expensive and the most feasible, even in not particularly well equipped units.
