Современный стандарт лечения – иммунохимиотерапия первой линии на основе ритуксимаба (R-CHOP и CHOP-подобные режимы) – демонстрирует высокую эффективность, обеспечивая достижение полного ответа у большинства пациентов. Однако у 8–25 % больных в процессе или после завершения лечения развиваются локальные жизнеугрожающие осложнения, среди которых ведущее место занимает механическая обструкция выходного отдела желудка (пилоростеноз). В рутинной практике плановое хирургическое вмешательство у пациентов с лимфомами, как правило, не применяется, так как данный вид опухолей высокочувствителен к лекарственной терапии.</p><p>В статье на примере клинического случая пациента 49 лет с экстранодальной В-клеточной лимфомой желудка IV стадии и ВИЧ-положительным статусом продемонстрирована роль паллиативного оперативного вмешательства. Несмотря на достижение частичного метаболического ответа на полихимиотерапию (схемы EPOCH/R-CHOP), у пациента развился декомпенсированный рубцово- опухолевый стеноз привратника. Данное осложнение потребовало активной хирургической тактики. В качестве паллиативного вмешательства была успешно выполнена гастроэнтеростомия, что позволило создать обходной путь для эвакуации пищи из желудка в тощую кишку, минуя зону обструкции, и существенно улучшить качество жизни пациента. Послеоперационный период протекал без осложнений, в отдаленном периоде наблюдения отсутствовали признаки прогрессирования основного лимфопролиферативного заболевания. Дополнительным преимуществом выбранного хирургического подхода явилось быстрое восстановление нутритивного статуса пациента с возможностью сохранения перорального питания.</p><p>Представленное клиническое наблюдение подтверждает целесообразность индивидуального подхода к выбору метода паллиативного лечения у пациентов с осложненным течением лимфомы желудка.</p></abstract><trans-abstract xml:lang="en"><p>Primary gastric non- Hodgkin lymphomas represent the most common extranodal localization of lymphoproliferative disorders. The current standard of care, first-line immunochemotherapy based on rituximab (R-CHOP and CHOP-like reg imens), demonstrates high efficacy, achieving complete response in the majority of patients. However, 8–25 % of patients develop local life-threatening complications during or after treatment, among which gastric outlet obstruction (pyloric stenosis) is the most common. In routine clinical practice, elective surgical intervention is generally not performed in patients with lymphomas because these tumors are highly sensitive to systemic drug therapy.</p><p>This article presents a clinical case of a 49-year-old patient with stage IV extranodal B-cell gastric lymphoma and HIV-positive status, demonstrating the role of palliative surgical intervention. Despite achieving a partial metabolic response to polychemotherapy (EPOCH/R-CHOP regimens), the patient developed decompensated cicatricial- tumorous pyloric stenosis. This complication required active surgical management. Gastrojejunostomy was successfully performed as a palliative procedure, creating a bypass for gastric emptying into the jejunum while circumventing the obstruction site, which significantly improved the patient's quality of life. The postoperative course was uneventful, and no signs of progression of the underlying lymphoproliferative disease were observed during long-term follow-up. An additional advantage of the selected surgical approach was the rapid restoration of the patient's nutritional status while preserving oral feeding.</p><p>The presented clinical case confirms the feasibility of an individualized approach to the selection of palliative treatment strategies in patients with complicated gastric lymphoma.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>неходжкинская лимфома желудка</kwd><kwd>пилоростеноз</kwd><kwd>паллиативное хирургическое вмешательство</kwd><kwd>гастроэнтероанастомоз</kwd><kwd>клиническое наблюдение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>primary gastric non-Hodgkin lymphoma</kwd><kwd>pyloric stenosis</kwd><kwd>palliative surgical intervention</kwd><kwd>gastroenterostomy</kwd><kwd>clinical case reports</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">Bai Z, Zhou Y.
