Пищевод Барретта предшествует развитию аденокарциномы, заболеваемость которой, по оценкам разных авторов, значительно возросла за последние десятилетия. Однако при своевременном выявлении и лечении пищевода Барретта и дисплазии эпителия на его фоне, возможно остановить неопластическую прогрессию и, в последующем, повлиять на снижение смертности населения от инвазивной аденокарциномы пищевода. В отделе эндоскопии МНИОИ им. П.А. Герцена за период 2012-2024 гг. проходили обследование 760 пациентов, у которых в ходе эзофагогастродуоденоскопии был выявлен пищевод Барретта. При этом, у мужчин заболевание закономерно выявлялось в 2 раза чаще, чем у женщин (526 против 254). Более чем у половины пациентов мы выявили длинный сегмент ПБ (55,3% [ДИ 95%: 51,7-58,8%]). Неопластические изменения эпителия были зарегистрированы нами у 177 обследуемых больных, что составило 23% от общего количества пациентов с ПБ. Установлено, что наибольшее количество неоплазий ПБ было выявлено на фоне длинного сегмента метаплазии (74,5% [ДИ 95%: 68,1%-80,9%]). Менее чем в 24% случаев [ДИ 95%: 17,4%-30,0%] неоплазии определялись в пределах короткого сегмента ПБ. Мы выделили ряд признаков, характерных для слабой и тяжелой дисплазии эпителия, а также неинвазивной аденокарциномы пищевода Барретта.</p></abstract><trans-abstract xml:lang="en"><p>Barrett’s esophagus (BE) is an precancerous condition in which the squamous epithelium of the esophagus is transformed into a columnar epithelium under the influence of the constant reflux of acid. Barrett’s esophagus precedes the development of adenocarcinoma, the incidence of which, according to various authors, has increased significantly over the past decades. However, with timely detection and treatment of Barrett’s esophagus and dysplasia, it is possible to stop neoplastic progression and, subsequently, affect the reduction of mortality from invasive adenocarcinoma of the esophagus. In the endoscopy department of the P.A. Herzen Moscow Oncology Research Institute, 760 patients were examined in 2012-2024, in whom Barrett’s esophagus was detected during upper endoscopy. The disease was detected in men 2 times more often than in women (526 vs 254). In more than half of the patients, we observed a long segment of BE metaplasia (55.3% [95% CI: 51.7%-58.8%]). Different types of epithelial neoplasia were detected in 177 examined patients, which accounted for 23% of the total number of patients with BE. It was found that the greatest number of be changes were detected within a long segment of metaplasia (74.5% [95% CI: 68.1%-80.9%]). In less than 24% of cases [95% CI: 17.4%-30.0%], neoplasias were found within the short segment of BE. We identified a number of signs of low- and high-grade dysplasia, as well as non-invasive Barrett’s carcinoma.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пищевод Барретта</kwd><kwd>дисплазия эпителия</kwd><kwd>рак на фоне пищевода Барретта</kwd><kwd>эзофагогастродуоденоскопия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Barrett’s esophagus</kwd><kwd>epithelial dysplasia</kwd><kwd>cancer associated with Barrett’s esophagus</kwd><kwd>upper endoscopy</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">Spechler S.J., Souza R.F.
