Исследованы результаты биопсии печени во время операции, а также пункционной биопсии печени через 5 дней и через 3 недели после декомпрессионных операций. Выявлены выраженные структурные и функциональные изменения ткани печени, которые прогрессировали с увеличением длительности окклюзии. В случаях с длительной хронической желтухой после декомпрессии желчных протоков в портальных трактах остаются склеротические изменения, гистиолимфоцитарная инфильтрация и пролиферирующий билиарный эпителий. Исследование пункционных и интраоперационных биопсий при механической желтухе позволяет определить форму и тяжесть холестаза, что совместно с другими данными влияет на прогноз заболевания и на тактику оперативного лечения. При холестазах различной длительности необходимо как можно раньше проводить мероприятия, направленные на коррекцию нарушений морфологии печени.</p></abstract><trans-abstract xml:lang="en"><p>The morphological state of the liver was analyzed in 145 patients with cholestasis of non-neoplastic etiology, who were treated at the Novgorod Regional Clinical Hospital and the Central City Clinical Hospital of Veliky Novgorod. The results of liver biopsy during surgery, as well as puncture liver biopsy 5 days and 3 weeks after decompression operations were studied. There were pronounced structural and functional changes in liver tissue that progressed with increasing duration of occlusion. In cases with prolonged chronic jaundice, after decompression of the bile ducts, sclerotic changes, histiolymphocytic infiltration and proliferating biliary epithelium remain in the portal tracts. The study of puncture and intraoperative biopsies in obstructive jaundice makes it possible to determine the form and severity of cholestasis, which, together with other data, affects the prognosis of the disease and the tactics of surgical treatment. With cholestasis of varying duration, it is necessary to carry out measures as early as possible aimed at correcting violations of liver morphology.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пункционная и интраоперационная биопсия</kwd><kwd>морфология печени</kwd><kwd>холестазы неопухолевой этиологии</kwd><kwd>длительность окклюзии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>needle aspiration and intraoperative biopsy</kwd><kwd>morphology of the liver</kwd><kwd>cholestasis of non-tumor etiology</kwd><kwd>duration of occlusion</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Пышкин С.А., Димов П.Г., Пирогова И.Ю., Батанов А.Н.
