Proponents of the “routine” approach to biopsies argue that there is a risk of missing such pathologies as collagenous and lymphocytic colitis; opponents say about the low incidence of such pathologies, especially in children, which makes the strategy of routine biopsy ineffective.</p> <p><bold><italic>AIM</italic></bold><bold><italic>:</italic></bold> To identify the level of matching between endoscopic and histologic findings in colonoscopies in children. The secondary aim — 1 to identify predictors that impact the matching level between endoscopy and histology, as well as predictors which are highly informative on the consequent histologic changes.</p> <p><bold><italic>METHODS</italic></bold><bold><italic>:</italic></bold> A retrospective analysis of findings of colonoscopies in patients, aged 0–18, was made. Descriptive statistics and binary logistic regression were used to determine the level of matching and potential predictors of matching with abnormal histology.</p> <p><bold><italic>RESULTS</italic></bold><bold><italic>:</italic></bold> 500 colonoscopies were analyzed. Endoscopists revealed pathological changes in 92 (19.8%) patients, and histologists in 89 (17.8%). If to take histology as “the gold standard”, specificity of colonoscopy was 90.5%, sensitivity — 66.3%, accuracy — 86.2%, positive and negative predictive value — 87.5% and 72.5%. Endoscopic verification of the normal mucous was highly associated with the matching level [odds ratio (OR) 22.494, <italic>p</italic> &lt;0.001]. The established diagnosis of inflammatory bowel disease (OR 3.598, <italic>p</italic> &lt;0.001) and blood in stool (OR 2.557, <italic>p</italic>=0.022) were strong predictors of pathological findings at histologic examination. Other factors (abdominal pain, weight loss, developmental delay, diarrhea, juvenile rheumatoid arthritis, endoscope model and endoscopist’s experience) did not have a statistically significant impact at the matching level and we’re not predictors of pathological findings at histology (<italic>p</italic> &gt;0.05).</p> <p><bold><italic>CONCLUSION</italic></bold><bold><italic>:</italic></bold> Our data have demonstrated a good matching level between endoscopic and histologic findings, especially in case of the normal colon mucous. Predictors of abnormal histology were also identified: inflammatory bowel disease and blood in stool. At the same time, abdominal pain, weight loss, diarrhea and juvenile rheumatoid arthritis in combination with normal colon mucous at the endoscopic examination were not associated with abnormal histology. Future multicenter researches are needed to obtain the evidence base for the strategy of selective biopsies during colonoscopy in children.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование</bold><bold>.</bold> Общепринятой практикой в течение последних 40 лет являются «рутинные» биопсии во время колоноскопии у всех детей. Сторонники «рутинного» подхода к биопсиям утверждают, что существует риск пропустить коллагенозный или лимфоцитарный колит. Противники говорят о низкой частоте встречаемости этой патологии, особенно у детей, что делает стратегию рутинных биопсий неэффективной.</p> <p><bold>Цель.</bold> Определить уровень согласованности между эндоскопическими и гистологическими данными при колоноскопии у детей. Второстепенная цель — выявить предикторы, влияющие на согласованность результатов эндоскопических и гистологических исследований, а также предикторы, позволяющие с высокой вероятностью выявлять последующие гистологические изменения.</p> <p><bold>Методы.</bold> Ретроспективный анализ колоноскопий пациентов в возрасте от 0 до 18 лет. Для определения показателей совпадений и потенциальных предикторов согласованности и нахождения патологии в ходе гистологии использовались описательная статистика и бинарная логистическая регрессия.</p> <p><bold>Результаты.</bold> Проанализировано 500 колоноскопий. Эндоскописты выявили патологические изменения у 98 (19,6%) пациентов, а гистологи — у 89 (17,8%). При учёте гистологии в качестве «золотого стандарта», специфичность колоноскопии составила 90,5%, чувствительность — 66,3%, точность — 86,2%, положительная и отрицательная прогностическая значимость — 87,5% и 72,5%. Эндоскопическая верификация неизменённой слизистой оболочки была в высокой степени связана с согласованностью результатов [отношение шансов (ОШ) 22,494, <italic>p</italic> &lt;0,001]. Диагностированное воспалительное заболевание кишечника (ОШ 3,598, <italic>p</italic> &lt;0,001) и кровь в стуле (ОШ 2,557, <italic>p</italic>=0,022) были сильными предикторами патологических находок в ходе гистологического исследования. Другие факторы (боли в животе, потеря веса, отставание в развитии, диарея, ювенильный ревматоидный артрит, модель эндоскопа и опыт врача эндоскописта) не оказали статистически значимого влияния на согласованность результатов и не являлись предикторами выявления патологического результата на гистологии (<italic>p</italic> &gt;0,05).</p> <p><bold>Заключение.</bold> Результаты нашего исследования свидетельствуют о хорошей согласованности между эндоскопическими и гистологическими данными, особенно когда эндоскопист диагностирует неизменённую слизистую оболочку толстой кишки. Были выявлены предикторы патологических изменений на гистологическом исследовании: воспалительное заболевание кишечника и кровь в стуле. В то же время боли в животе, потеря веса, диарея и ювенильный ревматоидный артрит в сочетании с неизменённой слизистой оболочкой не связаны с выявлением патологии в ходе гистологического исследования. Необходимы многоцентровые исследования для сбора доказательной базы стратегии выборочного взятия биопсий во время колоноскопии у детей.</p></trans-abstract><kwd-group xml:lang="en"><kwd>colonoscopy</kwd><kwd>histology</kwd><kwd>matching</kwd><kwd>biopsy</kwd><kwd>children</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>колоноскопия</kwd><kwd>гистология</kwd><kwd>соответствие</kwd><kwd>биопсии</kwd><kwd>дети</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Pall H, Zacur GM, Kramer RE, et al.
