Abstract: Изобретение относится к области медицины, а именно к способам ультразвуковой диагностики сократительной способности гастродуоденального перехода. Осуществляют ультразвуковое сканирование продольного среза гастродуоденального перехода. Дополнительно проводят ультразвуковое сканирование поперечного среза гастродуоденального перехода и осуществляют измерение толщины его мышечного слоя по передней, верхней, задней и нижней стенке как в фазу полного раскрытия просвета, так и в фазу максимального смыкания. Затем определяют индекс степени сокращения гастродуоденального перехода. Индекс рассчитывают по формуле I S =((L 1 +L 2 +L 3 +L 4 )×100)/(R 1 +R 2 +R 3 +R 4 )-100, где I S  - индекс степени сокращения; L 1 , L 2 , L 3 , L 4  - толщина мышечного слоя соответственно по передней, верхней, задней и нижней стенке в фазу максимального смыкания, R 1 , R 2 , R 3 , R 4  - толщина мышечного слоя соответственно по передней, верхней, задней и нижней стенке в фазу полного раскрытия гастродуоденального перехода. При индексе степени сокращения равном или более 50% - определяют нормальное состояние сократительной способности гастродуоденального перехода. При индексе степени сокращения менее 50% - определяют нарушение сократительной способности гастродуоденального перехода.
