title: [On the value of the magnifying optic of Lent in laparoscopy) (author's transl)].
abstract: 103 non selected patients underwent laparoscopy with the photolaparoscope equipped first with Luminaoptic and subsequently with the magnifying optic of Lent (Wolf GmbH, Knittlingen, W-Germany). The results are compared with the histologic findings and among each other. In 83.5% there was a satisfactory correlation between laparoscopy and histological findings, in 16.5% there was none. It was only in 2.9% of all cases that a different diagnosis resulted by means of the magnifying optic. From these results it is concluded that the magnifying optic does not provide a higher effectivity of laparoscopy. Thus the magnifying optic should be preserved for instruction.
