Проявления постковидного синдрома весьма вариабельны. В патологический процесс могут вовлекаться практически все органы и системы. В представленном сообщении целенаправленно анализируются и обсуждаются два клинических случая проявления постковидного синдрома, обусловленных дисфункцией желудочно-кишечного тракта. В одном случае постковидный синдром проявился манифестацией диспепсических расстройств. В ходе обследования не подтвердился функциональный характер патологии. Во-втором наблюдался диарейный синдром, возникший через 2 месяца после перенесенной инфекции SARS-CoV-2. Особенность наблюдения в том, что у больной, страдавшей дивертикулярной болезнью ободочной кишки, наблюдался быстрый рост полипа сигмовидной кишки. Обсуждается вопрос о влиянии инфекции на прогрессирование опухолевого процесса.</p></abstract><trans-abstract xml:lang="en"><p>The article analyzes the problem of post-COVID syndrome, which is formed in a number of patients after an infection caused by the SARS-CoV-2 virus. The manifestations of the post-COVID syndrome are highly variable. Almost all organs and systems can be involved in the pathological process. In the presented report, two clinical cases of manifestation of post-COVID syndrome caused by dysfunction of the gastrointestinal tract are purposefully analyzed and discussed. In one case, the post-COVID syndrome manifested itself as a manifestation of dyspeptic disorders. The examination did not confrm the functional nature of the pathology. In the second case, a diarrheal syndrome was observed that arose 2 months after the infection with SARS-CoV-2. The peculiarity of the observation is that in a patient suffering from diverticular disease of the colon, a rapid growth of the polyp of the sigmoid colon was observed. The issue of the inﬂuence of infection on the progression of the tumor process is discussed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>инфекция COVID-19</kwd><kwd>постковидный синдром</kwd><kwd>диспепсические расстройства</kwd><kwd>нарушение функции кишечника</kwd><kwd>опухолевый процесс</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19 infection</kwd><kwd>post-COVID syndrome</kwd><kwd>dyspeptic disorders</kwd><kwd>intestinal dysfunction</kwd><kwd>tumor process</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">Ивашкин В.Т., Шептулин А.А., Зольникова О.Ю. и др.
