Fifty-one patients with temporal lobe DRE were examined using clinical, neuroimaging, electro- physiological, and laboratory research methods from June 2020 to June 2023. Anteromedial temporal lobectomy (AMLE) and selective amygdalohippocampectomy (SAHE) were performed in 38 (74.5%) and 13 (25.5%) cases, respectively. Postsurgery outcomes were evaluated in 51 patients 6 months later, continued in 43 and 20 patients 1 year and 2 years, respectively, afterwards.</p></sec><sec><title>Results</title><p>Results. The percentage of patients with significant improvement (Engel I/II) 6 months, 1 year and 2 years post-surgery was 82.4%, 72.1%, and 55.0%, respectively. After AMLE vs. SAHE, patients had a more favorable outcome while assessing seizure control. The predictors of unfavorable post-surgery outcome included a prolonged epilepsy course before surgery, the presence of electroencephalography-verified epileptiform activity in postoperative period, and repeated surgical intervention. Patient age, the presence of focal seizures evolving into bilateral tonic-clonic seizures as well as more frequent seizures before surgery were considered as potential predictors.</p></sec><sec><title>Conclusion</title><p>Conclusion. The study results show that quite high effectiveness of seizure control in postoperative period in temporal DRE is quite high that may be accounted for by probability of removing epileptogenic foci and suppression of the mechanisms ensuring emergence and irritation of epileptic discharges. Nevertheless, effectiveness of surgical treatment fades off with time, which requires to further investigate the negative factors countering long-term post-surgery effect. In connection with this, a special attention should be paid to factors such as the presence of electroencephalography-verified epileptiform activity in postoperative period, repeated surgical intervention as well as prolonged epilepsy before surgery.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель: оценка результатов хирургического лечения и выявление предикторов неблагоприятного исхода оперативного вмешательства у пациентов с височной фармакорезистентной эпилепсией (ФРЭ) в отдаленном послеоперационном периоде.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. За период с июня 2020 г. по июнь 2023 г. проведено обследование 51 пациента с височной ФРЭ после оперативного лечения с использованием клинических, нейровизуализационных, электрофизиологических, лабораторных методов. В 38 случаях (74,5%) была проведена антеромедиальная височная лобэктомия (АМВЛЭ), в 13 (25,5%) – селективная амигдалогиппокампэктомия (САГЭ). Исходы хирургического вмешательства оценены у 51 больного через 6 мес после операции, далее у 43 человек через 1 год и у 20 – через 2 года.</p></sec><sec><title>Результаты</title><p>Результаты. Доли пациентов со значительным улучшением (классы I/II по классификации Engel) через 6 мес, 1 год и 2 года составили 82,4%, 72,1% и 55,0% соответственно. У больных после АМВЛЭ наблюдался более благоприятный исход с точки зрения контроля приступов по сравнению с пациентами, у которых была проведена САГЭ. К предикторам неблагоприятного исхода оперативного лечения отнесены длительное течение эпилепсии до вмешательства, наличие эпиактивности по данным электроэнцефалографии в послеоперационном периоде, повторная хирургическая операция. Как потенциально возможные предикторы рассматривались возраст, наличие фокальных приступов с эволюцией в билатеральные тонико-клонические и частые приступы до операции.</p></sec><sec><title>Заключение</title><p>Заключение. Результаты проведенного исследования показывают, что эффективность контроля приступов в после- операционном периоде у пациентов с височной ФРЭ достаточно высока. Это объясняется большой вероятностью удаления эпилептогенных очагов и купирования механизмов, обеспечивающих возникновение и ирритацию эпилептических разрядов. Тем не менее со временем эффективность хирургического лечения уменьшается, что требует дополнительного изучения негативных факторов, снижающих долгосрочной эффект оперативного вмешательства. В связи с этим особое внимание следует уделять таким факторам, как наличие эпиактивности по данным электроэнцефалографии в послеоперационном периоде, повторное хирургическое вмешательство, длительное течение эпилепсии до операции.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Височная фармакорезистентная эпилепсия</kwd><kwd>ФРЭ</kwd><kwd>хирургия эпилепсии</kwd><kwd>склероз гиппокампа</kwd><kwd>предикторы неблагоприятного исхода</kwd><kwd>классификация исходов операции Engel</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Temporal drug-resistant epilepsy</kwd><kwd>DRE</kwd><kwd>epilepsy surgery</kwd><kwd>hippocampal sclerosis</kwd><kwd>predictors of unfavorable outcome</kwd><kwd>Engel classification of surgical outcomes</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">Kalilani L., Sun X., Pelgrims B., et al.
