Глубокий кистозный гастрит (ГКГ) представляет собой редкую форму хронического гастрита, характеризующуюся кистозным расширением желез в слизистой оболочке и подслизистом слое стенки желудка. Несмотря на наличие описанных эндоскопических и морфологических признаков, патология остаётся недостаточно изученной. Цель. Оценка эндоскопических и эндосонографических характеристик ГКГ по данным клинических наблюдений, обнаруженных в условиях отделения эндоскопии МНИОИ им. П.А. Герцена. Материалы и методы. Проведен ретроспективный анализ 5 случаев ГКГ, выявленных в МНИОИ им. П. Герцена за период 2012-2024 гг. Результаты. В ходе анализа установлено, что у большинства пациентов (80%) наблюдались булавовидно утолщённые складки слизистой оболочки с бугристой поверхностью. При эндосонографии в 100% случаев были выявлены анэхогенные кисты в слизистой оболочке и/или подслизистом слое стенки желудка. В одном из наблюдений был зарегистрирован уникальный случай ГКГ в зоне гетеротопии желудочной слизистой оболочки в пищеводе, что представляет собой редкое явление в мировой практике. Диагноз ГКГ был морфологически подтверждён у всех пациентов, в том числе при помощи петлевой электрорезекции фрагмента слизистой оболочки и подслизистого слоя стенки желудка. Заключение. Результаты исследования подтверждают важность комплексного эндоскопического исследования для точной диагностики ГКГ и его дифференциации с другими патологиями желудка. Полученные данные свидетельствуют о необходимости дальнейших исследований в области патогенеза ГКГ, в частности - его онкогенного потенциала.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. Gastritis cystica profunda (GCP) is a rare form of chronic gastritis characterized by cystic dilation of glands in the mucosa and submucosal layer of the gastric wall. Despite the presence of the described endoscopic and morphological signs, the pathology remains insufficiently studied. Objective. Evaluation of endoscopic and endosonographic characteristics of GCP based on clinical observations detected in the endoscopy department of the P.A. Hertsen Moscow Oncology Research Institute. Materials and methods. A retrospective analysis of 5 cases of GCP detected in the P.A. Hertsen Moscow Oncology Research Institute in 2012-2024 was conducted. Results. The analysis revealed that most patients (80%) had club-shaped thickened folds of the mucous membrane with a bumpy surface. Endosonography revealed anechoic cysts in the mucosa and/or submucosal layer of the stomach wall in 100% of cases. In one of the observations, a unique case of GCP was registered in the zone of heterotopia of the gastric mucosa in the esophagus, which is a rare phenomenon in world practice. The diagnosis of GCP was morphologically confirmed in all patients, including by loop electroresection of a fragment of the mucosa and submucosal layer of the stomach wall. Conclusion. The results of the study confirm the importance of a comprehensive endoscopic study for the accurate diagnosis of GCP and its differentiation from other gastric pathologies. The data obtained indicate the need for further research in the field of GCP pathogenesis, in particular, its oncogenic potential.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>глубокий кистозный гастрит</kwd><kwd>эзофагогастродуоденоскопия</kwd><kwd>эндосонография</kwd><kwd>рак желудка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gastritis cystica profunda</kwd><kwd>esophagogastroduodenoscopy</kwd><kwd>endosonography</kwd><kwd>gastric cancer</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">Shimizu S., Hara H., Muto Y., Kido T., Miyata R.
