INFLUENCE OF FEDOROV,S.P. APPROACH ON THE MORPHOFUNCTIONAL CONDITION OF THE ANTERIOR ABDOMINAL-WALL ACCORDING TO THE FINDINGS OF ULTRASONICEXAMINATION

Echolocation was accomplished by means of ''Alok-650'' echochamber (Ja pan) and 3.5 and 5 megahertz transducers. Twenty individuals of the co ntrol group and 40 patients who underwent operations on the extrahepat ic bile ducts and the gallbladder through S. P. Fedorov's approach wer e examined. Morphometry was conducted of the linea alba, the broad abd ominal muscles, and the rectus abdominis muscles on 5 levels in relaxa tion and tension of the prelum abdominale muscles. The size of the rec tus abdominis muscles in the control group was found to be the same on both sides. Atrophy of the right rectus abdominis muscle was revealed in all patients who were operated on. The spread and depth of the atr ophic changes varied, Iri most cases the muscle was atrophied along it s whole length distal to the line of division. The atrophic changes we re maximum (22 %-62 % of the thickness of the symmetric area of the le ft rectus muscle) for a length of 2-3 cm below the operative incision. In the zone with most marked atrophic changes the muscle loses its pr operty of contraction in functional load of the prelum abdominale.
