DISTORSION AND CHROMATIC ABERRATION AS FACTORS OF DIAGNOSTIC INFORMATIVITY OF LAPAROSCOPIC IMAGES

It was established that maximal risk of images distortion is observed under condition of 2.0 mm laparoscopes usage (-13.7%), while minimal central distortion is observed in case of 10.0 mm laparoscope exploration (-3.26%), аnd minimal peripheral distortion in case of 5.0 mm laparoscope usage (-7.28%). In accordance to expert estimation distortion underlay 20.8% and 27.8% false-positive and false-negative minilaparoscopic diagnoses. In case of traditional laparoscopic diagnostics these figures were less prominent — 20.0% and 16.7% correspondently. Greatest impact of distortion (50.0%) was noted in case of false-positive traditional laparoscopic cholecystitis diagnostics. Distortion does not cause any influence upon incorrect diagnostics of the absence of pathology. The only exclusion were two cases of false-positive diagnoses which have been made in the course of traditional abdominal laparoscopy (16.7%).
