This phenomenon may lead to treatment failure, if therapy  does not take into account  the specific pathophysiological mechanisms  of the NERD and FD overlap.</p><p><bold>Aim</bold>: To study motility of the proximal and  distal parts  of the  stomach  in patients  with the overlap syndrome of NERD with FD.</p><p><bold>Materials and  methods:</bold>  The  study  enrolled  56  patients (34 women and 22 men), aged from 18 to 45 years, who met the diagnostic  criteria for NERD and FD (the Rome criteria III, esophageal endoscopy, 24-hour  pH  measurement  or  24-hour  impedance pH measurement), and  had  both  NERD  and  FD symptoms  simultaneously  (overlap); 46 healthy volunteers. The accommodation of the  proximal (fundal) part  of the  stomach  and  motility of the distal gastric part  was assessed  by ultrasonography (Aixplorer, SuperSonic Imagine, France, with convex probe  1–6 MHz) before  and  after the  intake of the liquid test food. The patients  filled in questionnaires to assess the symptoms  and their severity (scored from 0 to 3). The difference  between their mean ± standard  deviation (SD) values was assessed  by Students  t-test  and  was considered  significant at p &lt; 0.05.</p><p><bold>Results</bold>: After intake of the  liquid test  food, the  patients  with the  FD and NERD overlap syndrome demonstrated an advanced and statistically significant gastric motility abnormality  both  in its proximal and distal parts, compared to healthy control: accommodation disturbances and its reduction, decreased amplitude  (61.4 ± 7.5 vs 90.2 ± 6.9%, p &lt; 0.05), frequency of contractions of the antrum during 3-minute interval (4.3 ± 1.5 vs 9.7 ± 1.4, p &lt; 0.05), antral motility index (4.3 ± 1.4 vs 8.8 ± 1.3%, p &lt; 0.05), and gastric emptying   (37.1 ± 14.5   vs  69.1 ± 19.5%,  p &lt; 0.05). Gastric accommodation abnormalities  were associated with a statistically significant increase in the severity  of the  following  symptoms: abdominal distention, postprandial feeling of fullness, early satiety, eructation, and heartburn (р&lt; 0.05 for all symptoms).</p><p><bold>Conclusion:</bold> Detection  of gastric accommodation and evacuation  abnormalities  that determine the  overlap  syndrome,  indicate  some common  mechanisms  of pathophysiology of FD and NERD, which should be taken into account for therapy optimization.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность.</bold> Феномен перекреста двух расстройств – неэрозивной формы гастроэзофагеальной   рефлюксной   болезни   (НЭРБ) и  функциональной   диспепсии   (ФД) –  представляется важной клинической проблемой, поскольку у таких пациентов симптомы имеют большую выраженность  и частоту, чем у больных с НЭРБ или ФД без  перекреста.  Этот феномен  также становится  причиной  неудачной терапии больных, не учитывающей конкретные патофизиологические механизмы развития перекреста  НЭРБ и ФД. Цель – исследование  моторики проксимального  и дистального отделов желудка  у больных  с  синдромом  перекреста НЭРБ и ФД.</p><p><bold>Материал и методы.</bold> В исследование включены 56 пациентов (34 женского пола, 22 – мужского) в возрасте  от 18 до 45 лет, удовлетворявших    критериям    диагностики   НЭРБ и ФД (Римские критерии  III, эндоскопия  пищевода, 24-часовая рН-метрия или 24-часовая импеданс-рН-метрия), имевших одновременно симптомы НЭРБ и ФД (перекрест); 46 здоровых добровольцев. Исследование аккомодации проксимального (фундального) отдела желудка, моторики  дистального  отдела желудка проводили ультрасонографическим методом (аппарат   Aixplorer  (SuperSonic  Imagine,   Франция) с конвексным  датчиком  1–6 МГц)  до  и после приема тестовой жидкой пищи. Проводили анкетирование пациентов,  выявлявшее  наличие симптомов и их выраженность  (0–3 балла). Различие между сравниваемыми средними значениями показателей  оценивали с использованием величин стандартного отклонения (SD) и считали достоверным  при р &lt; 0,05 (критерий Стьюдента).</p><p><bold>Результаты.</bold> После принятия жидкой пищи у больных,  имевших перекрест  ФД и НЭРБ, отмечалось выраженное  статистически значимое нарушение моторики проксимального и дистального  отделов  желудка по сравнению со здоровыми  людьми: нарушение  аккомодации  и ее снижение, снижение  амплитуды (61,4 ± 7,5  против  90,2 ± 6,9%,  p &lt; 0,05),  частоты сокращений антрального отдела за 3-минутный интервал  (4,3 ± 1,5 против 9,7 ± 1,4, p &lt; 0,05), индексов  моторики  антрального  отдела  (4,3 ± 1,4 против  8,8 ± 1,3%, p &lt; 0,05) и опорожнения желудка  (37,1 ± 14,5  против  69,1 ± 19,5%,  p &lt; 0,05). Нарушение аккомодации желудка сопровождалось статистически значимым увеличением выраженности следующих симптомов: вздутие живота, постпрандиальное ощущение переполнения живота, чувство раннего насыщения, отрыжка, изжога (р &lt; 0,05 для всех симптомов).</p><p><bold>Заключение.</bold> Диагностика нарушений аккомодации и эвакуационной  функции желудка, обусловливающих развитие синдрома перекреста, свидетельствует об общности некоторых механизмов патогенеза ФД и НЭРБ, что следует учитывать при оптимизации терапии.</p></trans-abstract><kwd-group xml:lang="en"><kwd>overlap syndrome of functional dyspepsia with non-erosive reflux disease</kwd><kwd>gastric motility abnormalities</kwd><kwd>gastric accommodation</kwd><kwd>gastric emptying</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>синдром перекреста неэрозивной формы гастроэзофагеальной рефлюксной болезни и функциональной диспепсии</kwd><kwd>нарушения моторики желудка</kwd><kwd>аккомодация желудка</kwd><kwd>опорожнение желудка</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
