Трансанальная эндомикрохирургия (ТЭМ) является стандартом органосохраняющего лечения пациентов с крупными аденомами и ранним раком прямой кишки. Преимуществом ТЭМ в сравнении с другими трансанальными методами лечения опухолей прямой кишки является низкая частота R1-резекций и фрагментации, что реализуется в низком уровне местных рецидивов. Эндоскопическая подслизистая диссекция (ЭПД) – новая технология, аналогично направленная для лечения аденом и ранних форм рака прямой кишки. Этот систематический обзор и мета-анализ посвящен сравнению безопасности и эффективности ЭПД и ТЭМ при лечении крупных аденом и раннего рака прямой кишки.</p></sec><sec><title>ПАЦИЕНТЫ И МЕТОДЫ</title><p>ПАЦИЕНТЫ И МЕТОДЫ. Поиск литературы и мета-анализ данных производился в соответствии с the preferred reporting items for systematic reviews and meta-analyses checklist (PRISMA) в электронной базе Medline среди англоязычной литературы без ограничений по дате публикации (окончание 18.12.2018 г.) по ключевым словам: «endoscopic submucosal dissection», «esd», «endoscopic dissection», «tem», «tamis», «transanal endoscopic microsurgery», «transanal resection», «teo», «transanal endoscopic microsurgical excision». В систематический обзор включены все исследования, посвященные сравнению методов ТЭМ и ЭПД в лечении крупных аденом и раннего рака прямой кишки. Статистическую обработку данных при сравнении методик проводили в программе Review Manager 5.3.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ. Четыре ретроспективных сравнительных исследования включено в анализ. Анализируемые группы были сопоставимы и не отличались по количеству опухолей (Отношение шансов [ОШ]=1,19; 95% доверительный интервал [ДИ] 0,23-6,16) и размеру (р=0,55). Частота интраоперационных осложнений: кровотечение (р=0,54) и перфорация прямой кишки (р=0,32) также статистически значимо не различалась. Продолжительность операции в группе ЭПД на 32 мин. была статистически значимо больше, чем при выполнении ТЭМ (ОШ=32,5; 95% ДИ 17,7-47,4; р&lt;0,0001). Послеоперационный койко-день был больше в 1,6 раза после ТЭМ (ОШ=16,1; 95% ДИ 1,5-30,1; р=0,03). Частота использования антибиотиков после операции статистически значимо не различалась в обеих группах (р=0,33). Частота удаления опухоли единым блоком (р=0,66) и частота R1-резекций (р=0,74) статистически значимо не различались в обеих группах. Частота местных рецидивов не отличалась в обеих группах (р=0,95).</p></sec><sec><title>ВЫВОДЫ</title><p>ВЫВОДЫ. ЭПД и ТЭМ являются безопасными и эффективными методиками локального удаления аденом и раннего рака прямой кишки, однако необходимо проведение рандомизированного исследования для получения объективных результатов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>AIM</title><p>AIM: transanal endomicrosurgery (TEM) is the standard for organ-preserving treatment of patients with large adenomas and early rectal cancer. The advantage of TEM in comparison with other transanal methods of treatment of rectal tumors is the low frequency of R1 resections and fragmentation, which procudes a low level of local recurrences. Endoscopic submucosal dissection (ESD) is a new technology for superficial rectum tumors. This systematic review and meta-analysis compared safety and efficacy of ESD vs TEM for large adenoma and early colorectal cancer.</p></sec><sec><title>PATIENTS AND METHODS</title><p>PATIENTS AND METHODS: a literature search and meta-analysis of the data was carried out in accordance with the English-language Medline database without restrictions on the publication date (end December 18, 2018) according to keywords: «endoscopic submucosal dissection», «esd», «endoscopic dissection», «tem», «tamis», «transanal endoscopic microsurgery», «transanal resection», «teo», «transanal endoscopic microsurgical excision». The systematic review includes all papers on the comparison of TEM and ESD for large adenomas and early rectal cancer. Statistical data processing was performed using Review Manager 5.3.</p></sec><sec><title>RESULTS</title><p>RESULTS: four retrospective comparative studies were included in the analysis (215 patients). Groups were homogenous in the number of tumors (Odds ratio [OR]=1,19; 95% confidence interval [CI] 0.23-6.16) and size (p=0.55). The intraoperative morbidity included bleeding (p=0.54) and rectal perforation (p=0.32) was homogenous as well. The operation time in the ESD group was significantly longer by 32 minutes than TEM (OR=32.5;95% CI 17,7-47.4; p&lt;0.0001). Postoperative stay was higher than in 1.6 times after TEM (OR=16.1; 95% CI 1.5-30.1; p=0.03). The antibiotics use after surgery was not significantly different in both groups (p=0.33). The en-bloc resections (p=0.66) and the rate of R1 resections (p=0.74) were not significantly different in both groups. The local recurrence rate was homogenous (p=0.95).</p></sec><sec><title>CONCLUSIONS</title><p>CONCLUSIONS: the ESD and TEM procedures are safe and effective techniques for local excision of adenomas and early colorectal cancer, but a randomized study is needed to prove the results.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>аденома прямой кишки</kwd><kwd>ранний рак прямой кишки</kwd><kwd>трансанальная эндомикрохирургия</kwd><kwd>эндоскопическая подслизистая диссекция</kwd><kwd>систематический обзор</kwd><kwd>мета-анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Rectal adenoma</kwd><kwd>Early rectal cancer</kwd><kwd>Transanal endoscopic microsurgery</kwd><kwd>Endoscopic submucosal dissection</kwd><kwd>Systematic review</kwd><kwd>Meta-analysis</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">Чернышов С.В., Орлова Л.П., Жданкина С.Н., Кузнецов Н.С. и соавт.
