The average age of the patients was 53.5±8.5 years. The patients were divided into 2 groups by the type of laparoscopic surgery: in the first group (n=463), a 36 Fr calibration tube was used, the distance from the pyloric sphincter was 4–6 cm; in the second group (n=482), a 32 Fr calibration tube was used, the distance from the pyloric sphincter was 2–3 cm. The main comparison criteria was the percentage of body weight loss in the first 6 and 12 months, and an additional comparison criteria was the of concomitant diseases progress in postoperative and the existence of complications.</p> <p><bold>Results.</bold> A comparative analysis showed that the first group in the first 6 months lost 59±3% of its initial body weight, while in 12 months — 71±4%; in the second group, 73±3 and 87±3% of the initial weight, respectively. Concomitant diseases in the first group decreased by 70–80% by the 6th month after surgery and by 85–96% by the 12th month. In the 2nd group, similar remission with improvement was between 84 and 94% at the 6th month, and remained the same at the 12th month.</p> <p><bold>Conclusion.</bold> The results of the study show that in laparoscopic sleeve gastrectomy with a calibration tube diameter 32 Fr and a distance of 2–3 cm from the pyloric sphincter, compared to a calibration tube diameter 36 Fr or more and a distance of 4–6 cm from the pyloric sphincter, a body weight loss faster and more effective with earlier remission of concomitant diseases, while the number of complications is comparable.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель.</bold> Изучение влияния диаметра калибровочного зонда и расстояния от пилорического сфинктера на результаты лапароскопической продольной резекции желудка.</p> <p><bold>Методы.</bold> В исследование были включены 945 пациентов (915 женщин) с индексом массы тела 51,5±9 кг/м2. Средний возраст пациентов составлял 53,5±8,5 года. Пациенты были разделены на две группы в зависимости от типа лапароскопической операции. В первой группе (n=463) использовали калибровочной зонд 36 Fr, расстояние от пилорического сфинктера составляло 4–6 см; во второй группе (n=482) применяли калибровочной зонд 32 Fr, расстояние от пилорического сфинктера составляло 2–3 см. Основным критерием сравнения служил процентный показатель потери массы тела в первые 6 и 12 мес, а дополнительным критерием сравнения — послеоперационное течение сопутствующих заболеваний и наличие осложнений.</p> <p><bold>Результаты.</bold> Сравнительный анализ показал, что первая группа в первые 6 мес потеряла 59±3% своей первоначальной массы тела, через 12 мес — 71±4%; во второй группе — соответственно 73±3 и 87±3% исходной массы тела (р &lt;0,05). Сопутствующие заболевания в первой группе уменьшились на 70–80% к 6-му месяцу после операции и на 85–96% к 12-му месяцу. Во второй группе аналогичная ремиссия с улучшением на 6-м месяце составила 84–94%, а на 12-м месяце показатели остались на прежнем уровне (р &lt;0,05).</p> <p><bold>Вывод.</bold> Результаты исследования показывают, что при использовании калибровочного зонда 32 Fr и при расстоянии 2–3 см от пилорического сфинктера во время лапароскопической продольной резекции желудка по сравнению с применением калибровочного зонда 36 Fr и более при расстоянии 4–6 см от пилорического сфинктера происходит более быстрая и эффективная потеря массы тела с более ранним исчезновением сопутствующих заболеваний, количество осложнений сопоставимо.</p></trans-abstract><kwd-group xml:lang="en"><kwd>calibration tube</kwd><kwd>pyloric sphincter</kwd><kwd>longitudinal gastric resection</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>калибровочный зонд</kwd><kwd>пилорический сфинктер</kwd><kwd>продольная резекция желудка</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Berger E.R., Clements R.H., Morton J.M. et al.
