Сравнить безопасность и морфологическую информативность щипцовой и браш-биопсии у пациентов с опухолью Клацкина.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. За период 2013–2020 гг. чрескожное чреспеченочное холангиодренирование выполнено у 52 пациентов с опухолью Клацкина (27 женщин, 25 мужчин; средний возраст 59 лет). После этого антеградным доступом проведена верификация диагноза (74 процедуры): с 2013 по 2017 г. браш-биопсия (n = 36; 48,6 %) и с 2017 по 2020 г. щипцовая биопсия (n = 38; 51,4 %). Результаты биопсии были подтверждены последующим исследованием послеоперационного материала или клинико-рентгенологическими данными наблюдения пациентов.</p></sec><sec><title>Результаты</title><p>Результаты. Нежелательных явлений, связанных с браш-биопсией, не было. Отмечены осложнения у пациентов, связанные со щипцовой биопсией: в трех случаях (7,9 %) развилась гемобилия, которая была купирована консервативными методами в течение 1 сут. После выполнения 74 процедур биопсий у 52 больных злокачественное поражение желчевыводящих путей было выявлено при щипцовой биопсии в 79,0 %, а при браш-биопсии в 66,7 % случаев. Степень дифференцировки опухоли была определена у 60,0 % (n = 18) против 12,5 % (n = 3) (p &lt; 0,01) соответственно. Чувствительность и специфичность при щипцовой биопсии были выше, чем при браш-биопсии: 82,4 и 75,0 % против 73,3 и 66,7 % (p &gt; 0,05).</p></sec><sec><title>Выводы</title><p>Выводы. Эндобилиарная биопсия антеградным доступом является безопасной методикой как при браш-, так и при щипцовой методике. Однако при заборе материала щипцами увеличивается чувствительность и специфичность диагностики, возможность определения степени дифференцировки опухоли.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To evaluate the safety and accuracy of percutaneous transhepatic biliary biopsy in patients with suspected Klatskin tumor.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Between 2013–2020, percutaneous transhepatic biliary drainage (PTBD) was performed in 52 patients with Klatskin tumor, complicated by obstructive jaundice. After successful PTBD, the diagnosis was verified by antegrade access. 74 procedures were performed: brush (n = 36; 48.6 %) or forceps biopsies (n = 38; 51.4 %).</p></sec><sec><title>Results</title><p>Results. There were no adverse events associated with a brush biopsy. Only grade I complications were after the forceps technique: 3 patients (7.9 %) developed hemobilia, which was corrected conservatively. Malignant lesions of the biliary tract were detected by forceps technique in 79.0 %, brush biopsy in 66.7 % (p &gt;0,05). The degree of tumor differentiation was determined in 60.0 % (n = 18) vs 12.5 % (n = 3) (p &lt; 0,01), respectively.</p><p>Sensitivity and specificity of forceps biopsy were slightly higher than in brush: 82.4 % and 75.0 % vs 73.3 % and 66.7 % (p &gt;0,05).</p></sec><sec><title>Conclusions</title><p>Conclusions. Antegrade percutaneous transhepatic biliary biopsy is safe for both brush and forceps techniques. However, forceps biopsy has higher sensitivity and specificity in the diagnosis Klatskin tumor and better possibility of determining the degree of malignancy differentiation.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>внепеченочная холангиокарцинома</kwd><kwd>опухоль Клацкина</kwd><kwd>браш-биопсия</kwd><kwd>щипцовая биопсия</kwd><kwd>холангиодренирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cholangiocarcinoma</kwd><kwd>Klatskin tumor</kwd><kwd>brush biopsy</kwd><kwd>forceps biopsy</kwd><kwd>percutaneous transhepatic biliary drainage</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">Состояние онкологической помощи населению России в 2019 году.
