Хирургическое лечение «гантелевидных» нейрогенных опухолей поясничного отдела позвоночника остается дискутабельной темой в силу их сложного расположения, затрагивающего условные три анатомические зоны – позвоночный канал, забрюшинное пространство и фораминальный канал. Публикации о преимуществах и недостатках различных методов лечения единичны и показывают необходимость выработки персонифицированного подхода в решении данного вопроса. МАТЕРИАЛЫ И МЕТОДЫ. Проанализированы данные 47 (100 %) пациентов, оперированных по поводу нейрогенных опухолей гантелевидной формы в пояснично-крестцовом отделе позвоночника на базе Российского научно-исследовательского нейрохирургического института им. проф. А. Л. Поленова – филиала Федерального государственного бюджетного учреждения «Национальный медицинский исследовательский центр имени В. А. Алмазова» в период с 2015 по 2020 г., разделенных на три исследуемые группы, оперированных с помощью тубулярного ретрактора – 16 (34,4 %) пациентов, ранорасширителя Каспара – 15 (31,2 %) наблюдений, ранорасширителя Quadrant® – 16 (34,4 %) пациентов. Средний возраст пациентов составил 48,7 года (19–76 лет), среди них 27 (57,45 %) женщин и 20 (42,55 %) мужчин. Пациенты наблюдались как очно, с оценкой неврологического статуса, через 6 и 12 месяцев, так и дистанционно – анализ исследований магнитно-резонансной томографии через 3, 6, 12, 24 и 36 месяцев. РЕЗУЛЬТАТЫ. Среднее время хирургического вмешательства в группе с использованием тубулярного ретрактора составило 125 мин, в группе с ранорасширителем Каспара – 148 мин, в группе с ранорасширителем Quadrant® – 134 мин, средняя кровопотеря была сопоставима во всех группах и составила 210 (80–400) мл. Тотальная резекция опухоли была достигнута в 100 % случаев. Средняя длительность госпитализации составила 6 суток. При гистологической верификации опухолевой ткани выявлено соотношение шванном к нейрофибромам как 3:1 (35 (74,47 %) шванном и 12 (25,53 %) нейрофибром). Рецидив опухоли отмечен в 1 случае. ЗАКЛЮЧЕНИЕ. Опухоли пояснично-крестцового отдела «гантелевидной» формы можно удалять одноэтапно, тотально и безопасно для пациента при помощи малоинвазивных способов вне зависимости от применяемого хирургического доступа.</p></abstract><trans-abstract xml:lang="en"><p>INTRODUCTION. Surgical treatment of dumbbell tumors of the lumbar spine remains a discussible topic due to its complex location, affecting three conventional anatomical zones: the spinal canal, retroperitoneal space and foraminal canal. Many publications on the advantages and disadvantages of various treatment methods prove the need to develop a personalized approach to solving this issue. MATERIALS AND METHODS. The data of 47 (100 %) patients operated on for dumbbell tumors of the lumbosacral spine at the Polenov Neurosurgery Institute – the branch of Almazov National Medical Research Centre in the period from 2015 to 2020 were analyzed, divided into 3 study groups operated using: tubular retractor – 16 (34.4 %), Kaspar wound expander – 15   (31.2 %), Quadrant® wound expander – 16 (34.4 %). The average age of the patients was 48.7 (19–76 years), among them 27 (57.45 %) women and 20 (42.55 %) men. Access to the tumor and its resection were performed using a tubular retractor or a Kaspar wound expander by one surgical team. Patients were observed both face-to-face, with an assessment of neurological status, after 6 and 12 months, and remotely – an analysis of MRI studies after 3, 6, 12, 24 and 36 months. RESULTS. The average surgical intervention time in the tubular retractor group was 125 min, in the Kaspar wound dilator group – 148 min, in the Quadrant® wound dilator group – 134 min, the average blood loss was comparable in both groups and amounted to 210 (80–400 ml). Total tumor resection was achieved in 100 % of cases. The average duration of hospitalization was 6 days. Histological verification of the tumor tissue revealed a 3-to-1 ratio of schwannomas to neurofibromas (35 (74.47 %) schwannomas and 12 (25.53 %) neurofibromas). There was no recurrence of the tumor during the follow-up period. CONCLUSION. Dumbbell tumors of the lumbosacral region can be removed in one step, completely and safely for the patient using minimally invasive methods, regardless of the surgical access technique used.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гантелевидные опухоли</kwd><kwd>опухоль по типу «песочных часов»</kwd><kwd>персонифицированная хирургия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dumbbell tumors</kwd><kwd>hourglass-type tumor</kwd><kwd>personalized surgery</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">Harrop J.
