Несмотря на явное преимущество в непосредственных результатах трансанальной эндомикрохирургии перед мезоректумэктомией, лишь в малом количестве исследований сравнивались онкологические результаты. В связи с этим был выполнен систематический обзор литературы и метаанализ данных.</p><sec><title>ЦЕЛЬ ИССЛЕДОВАНИЯ</title><p>ЦЕЛЬ ИССЛЕДОВАНИЯ: сравнить непосредственные (частота осложнений, продолжительность операции и интраоперационной кровопотери) и отдаленные (частота возникновения отдаленных метастазов и локальных рецидивов) ТЭМ и мезоректумэктомии при раннем раке прямой кишки.</p></sec><sec><title>МАТЕРИАЛЫ И МЕТОДЫ</title><p>МАТЕРИАЛЫ И МЕТОДЫ: поиск литературы в соответствии с рекомендациями PRISMA. Статистическая обработка данных выполнена в программе Rewiew Manager 5.3.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ: в 4 исследованиях (1 радномизированное, 2 ретроспективных, 1 проспективное), вошедших в метаанализ, описаны результаты лечения 422 пациентов (240 — ТЭМ, 182 — мезоректумэктомия). Отношение шансов частоты возникновения послеоперационных осложнений после мезоректумэктомии была практически в 5 раз выше, чем после ТЭМ (ОШ 0,21; 95% ДИ: 0,060,74; р = 0,02), как и частоты повторных вмешательств по поводу осложнений (ОШ 0,16; 95% ДИ: 0,060,59; р = 0,02). Общая частота возврата заболевания в группе ТЭМ статистически значимо была выше, чем при выполнении тотальной мезоректумэктомии (ОШ 2,37; 95% ДИ: 1,045,39; р = 0,04), также как и частота местного рецидивирования (ОШ 4,61; 95% ДИ: 1,0819,6; р = 0,04). В то же время, статистически значимые различия в частоте возникновения отдаленных метастазов отсутствовали (ОШ 01,0; 95% ДИ: 0,352,84; р = 1,0).</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ: трансанальная эндомикрохирургия является методом выбора и более безопасна в сравнении с мезоректумэктомией. Однако онкологические результаты зависят от многих факторов, наличие которых необходимо учитывать при планировании хирургического лечения раннего рака прямой кишки.</p></sec></abstract><trans-abstract xml:lang="en"><p>Transanal endomicrosurgery (TEM) presently is the only method for local excision of early rectal cancer with sufficient visualization, possibility for full-wall excision to achieve adequately deep margin of resection for disease staging. Despite the obvious advantage in immediate outcomes of transanal endomicrosurgery over mesorectumectomy, nowadays only in a small number of studies the oncological outcomes were compared. In this regard were performed a systematic review of literature and meta-analysis.</p><sec><title>AIM OF THE STUDY</title><p>AIM OF THE STUDY: to compare the immediate (frequency of complications, duration of operation and intraoperative blood loss) and long-term (frequency of distant metastases and local recurrences) results of TEM and mesorectumectomy in early rectal cancer.</p></sec><sec><title>MATERIALS AND METHODS</title><p>MATERIALS AND METHODS: literature search was performed according to PRISMA guidelines. Statistical processing of data was performed with use of Review Manager 5.3. Program.</p></sec><sec><title>RESULTS</title><p>RESULTS: in 4 studies (1 randomized, 2 retrospective, 1 prospective), that were included in meta-analysis the results of treatment of 422 patients were described (240-TEM, 182-mesorectumectomy). The odds-ratio of incidence of postoperative complications after mesorectumectomy was higher for almost 5 times than after TEM (OR 0,21; 95% CI: 0,06 0,74; p = 0,02), as well as the frequency of reoperations in case for complications (OR 0,16; 95% CI: 0,06 0,59; p = 0,02). As well as the overall recurrence rate in TEM group (OR 2,37; 95% CI:1,04 5,39 p = 0,04), the rate of local recurrence (OR 4,61; 95% CI: 1,08 19,6; p = 0,04) was statistically higher than in total mesorectumectomy. At the same time there were no statistically significant difference in incidence of distant metastases (OR 01,0; 95% CI: 0,35 2,84; p = 1,0).</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: transanal endomicrosurgery is the method of choice and is safer than mesorectumectomy. However, oncological outcomes depend on many factors which presence must be taken into account when planning for surgical treatment of early rectal cancer.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>трансанальная эндомикрохирургия</kwd><kwd>мезоректумэктомия</kwd><kwd>метаанализ</kwd><kwd>систематический обзор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>transanal-endomicrosurgery</kwd><kwd>mesorectumectomy</kwd><kwd>metanalysis</kwd><kwd>systematic review</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">Bray F, Ferlay J, Soerjomataram I, et al.
