В большинстве субъектов Российской Федерации в условиях пандемии инфекции COVID-19 за первые 6 месяцев 2021 года наблюдался рост как уровня общей смертности от заболеваний органов пищеварения, так и показателей смертности от язвенной болезни, болезней печени и поджелудочной железы по сравнению с аналогичным периодом 2020 г. Это может быть связано как с неблагоприятным влиянием перенесенной коронавирусной инфекции на течение исходно имевшихся заболеваний пищеварительной системы, так и с возникшими в условиях пандемии трудностями в оказании специализированной медицинской помощи гастроэнтерологическим больным. Совершенствование амбулаторно-поликлинической помощи и дистанционное консультирование пациентов, а также успешная реализация образовательных программ смогут снизить показатели смертности от гастроэнтерологических заболеваний.</p></sec><sec><title>Заключение</title><p>Заключение. В период пандемии новой коронавирусной инфекции в большинстве регионов России наблюдается рост смертности от болезней органов пищеварения, что объясняется неблагоприятным влиянием SARS-CoV-2 на их течение, а также возникающими трудностями в оказании специализированной медицинской помощи.</p></sec><sec><title> </title><p> </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim.

In most subjects of the Russian Federation, the first half of 2021 enduring the COVID-19 pandemic has witnessed a higher overall mortality from digestive diseases and from peptic ulcer, liver and pancreatic illnesses compared to the same period in 2020. This situation may have roots in both the adverse impact of coronavirus infection on pre-existing digestive diseases and shortages in providing specialty medical aid to gastroenterological patients during the pandemic. Improved outpatient care and remote counselling, as well as successful educational measures, may reduce gastroenterological disease-associated mortality.</p></sec><sec><title>Conclusion</title><p>Conclusion.
