The risk of adenocarcinoma in BE patients increases with the extension of segment length and with the presence of dysplasia. Columnar-lined esophagus (CLE) devoid goblet cells is also associated with dysplasia and adenocarcinoma, however, with a lower risk. <bold>Aim</bold>: To perform clinical and morphological analysis of patients with BE with goblet cells and CLE devoid goblet cells on the presence or absence of dysplasia. <bold>Materials and methods</bold>: This prospective clinical morphological study included 78 patients with columnar-lined esophagus at EGDS, among them 20 patients with a long segment, 58 patients with a short segment. Biopsy specimens from the CLE area of the distal part of the esophagus were stained by hematoxylin and eosin and standard PAS-reaction with Alcian blue. Histological examination showed BE with goblet cells in 49 patients and CLE devoid goblet cells in 29 patients. In those with BE, the morphometric analysis of the goblet cells density was performed and the number of the affected crypts was counted in dysplastic fragments. <bold>Results</bold>: In the short segment group, the male to female ratio was ~ 1:1.1, and CLE devoid goblet cells was found in 53% of cases (27/58 patients), and BE with goblet cells in 57% of cases (31/58 patients). In the long segment group, the male to female ratio was ~ 2.3:1, along with predominance of BE with goblet cells cases (18/20 patients, 90%) and high density of goblet cells (11/18 patients, 61%). The rates of goblet cells detection increased with the extension of the segment length (p &lt; 0.05). The relative goblet cells density in the patients with the long BE segment was also significantly higher than in the short segment group (p &lt; 0.001). Advanced inflammatory infiltration was found in 22 of 58 (38%) cases with the short segment and in 13 of 20 patients with the long one (65%, p = 0.012). The rates of erosion in the long segment group were 1.62-fold higher and ulcerations 3.87-fold higher (p = 0.014). Esophageal dysplasia was identified in 10 of 20 cases (50%) with the long segment and in 2 of 58 cases (3.4%) with the short segment. In 10 of 12 cases (83.3%) dysplasia was multifocal and involved from 2 to 10 crypts (in total, up to 25 crypts). <bold>Conclusion</bold>: The long segment of metaplasia was associated with higher rates of active chronic esophagitis, higher presence of goblet cells and their higher density. Dysplasia was found in 10 patients with three and more risk factors of progression (male gender, long segment, hiatal hernia, etc.). In most cases, the biopsy samples showed multiple foci of dysplasia.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность</bold>. Пищевод Барретта (ПБ) - облигатное предраковое заболевание пищевода. Риск развития аденокарциномы пищевода у пациентов с ПБ повышается с увеличением длины сегмента метаплазии и при наличии дисплазии. При цилиндроклеточной метаплазии (ЦМ) пищевода также может развиваться дисплазия и аденокарцинома, однако риск у таких пациентов меньше. <bold>Цель</bold> - провести клинико-морфологический анализ у пациентов с ПБ и ЦМ пищевода в зависимости от наличия / отсутствия дисплазии. <bold>Материал и методы</bold>. В проспективное клинико-морфологическое исследование вошли 78 пациентов c определением сегментов метаплазии дистального отдела пищевода при эзофагогастродуоденоскопии, в том числе 20 пациентов с длинным сегментом и 58 - с коротким. Биопсированные фрагменты из сегментов ЦМ дистального отдела пищевода окрашивали гематоксилином и эозином, проводили ШИК-реакцию в сочетании с альциановым синим по стандартной методике. У 49 пациентов при патоморфологическом исследовании обнаружили ПБ, у 29 - ЦМ пищевода. При ПБ проводили морфометрический анализ плотности бокаловидных клеток (БК), во фрагментах с наличием дисплазии подсчитывали количество вовлеченных крипт. <bold>Результаты</bold>. При коротком сегменте метаплазии дистального отдела пищевода соотношение мужчин и женщин составило «1:1,1, ЦМ обнаруживалась в 53% случаев (27 из 58 пациентов), а ПБ - в 57% (31 из 58 пациентов). При длинном сегменте метаплазии соотношение мужчин и женщин было 2,3:1, значительно преобладали случаи ПБ (18 из 20 пациентов, 90%) с высокой плотностью БК (11 из 18 пациентов, 61%). Частота обнаружения БК возрастала с увеличением длины метаплазированного сегмента пищевода (p &lt; 0,05), относительная плотность БК при длинном сегменте ПБ также была значительно выше, чем при коротком (p &lt; 0,001). При коротком сегменте выраженная воспалительная инфильтрация наблюдалась в 22 случаях из 58 (38%), а при длинном - у 13 из 20 пациентов (65%, p = 0,012); при длинном сегменте эрозии выявлены в 1,62 раза чаще, а участки изъязвления - в 3,87 раза чаще (p = 0,014). У 10 из 20 (50%) пациентов с длинным и у 2 из 58 (3,4%) с коротким сегментом метаплазии пищевода обнаружена дисплазия пищевода. В 10 из 12 случаев (83,3%) дисплазия носила мультифокальный характер и занимала от 2 до 10 крипт, суммарно - до 25 крипт. <bold>Заключение</bold>. При длинном сегменте метаплазии возрастала частота активного хронического эзофагита, а также частота обнаружения БК и их плотность. Дисплазия выявлена у 10 пациентов с наличием 3 и более факторов риска прогрессии (мужской пол, длинный сегмент метаплазии, наличие хиатальной грыжи и др.). В большинстве наблюдений в биоптатах определялись множественные фокусы дисплазии.</p></trans-abstract><kwd-group xml:lang="en"><kwd>columnar-lined esophagus</kwd><kwd>Barrett's esophagus</kwd><kwd>low grade and high grade dysplasia</kwd><kwd>carcinogenesis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>цилиндроклеточная метаплазия пищевода</kwd><kwd>пищевод Барретта</kwd><kwd>low-grade и high-grade дисплазия</kwd><kwd>канцерогенез</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
