Систематизировать собственный опыт диссекций в подслизистом слое, отразить специфику эндоскопического вмешательства в зависимости от локализации новообразований в различных отделах толстой кишки, описать возникшие при этом осложнения.</p></sec><sec><title>ПАЦИЕНТЫ И МЕТОДЫ</title><p>ПАЦИЕНТЫ И МЕТОДЫ. В период с января 2017 по январь 2018 гг. в исследование включено 113 пациентов с новообразованиями толстой кишки, среди них женщин – 66, мужчин – 47. Все пациенты были разделены на две группы в зависимости от локализации опухоли. Всем больным выполнялось стандартное предоперационное обследование, включавшее ректороманоскопию и колоноскопию, эзофагогастродуоденоскопию, УЗИ брюшной полости и малого таза. После чего выполнялась диссекция в подслизистом слое по классической методике: разметка, инъекция, циркулярный разрез, подслизистая диссекция. Проведен статистический анализ полученных результатов.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ. Анализ результатов показал, что пациентов с опухолями, расположенными в правых отделах толстой кишки было несколько больше 61/113 (54%). LST (латерально стелящиеся опухоли) чаще встречались в I группе, чем во II: 56 (91,8%) и 38 (73,1%), соответственно, (p=0,03). Средний размер (М±SD) новообразований в правых отделах составил 31±13 (7-80) мм, а в левых – 29±11 (8-76). В 9/113 (8%) наблюдениях произошла конверсия ESD в резекцию, при этом во всех случаях причиной послужил неудовлетворительный лифтинг – менее 2 мм. Большинство опухолей были удалены en bloc, частота фрагментации при локализации в правых отделах после ESD составила 9%, а в левых – 10,4%, р=1,0. Интраоперационные осложнения развились у 2/56 (3,5%) больных с опухолями правых отделов и у 2/48 (4,1%) пациентов с опухолями, расположенными в левых отделах толстой кишки, р=1,0. Послеоперационные осложнения отмечены всего у двух пациентов: 2/104 (1,9%). В 9/113 (8%) случаев при патоморфологическом исследовании удаленных образований была выявлена аденокарцинома. В 2 (1,7%) наблюдениях в ходе контрольной колоноскопии установлен рецидив опухоли. ЗАКЛЮЧЕНИЕ. Эндоскопическая подслизистая диссекция является безопасным методом удаления аденом толстой кишки с частотой интра- и послеоперационных осложнений 3,5% и 1,9%, соответственно, и уровнем местных рецидивов 2,04%. Лифтинг опухоли менее 2 мм в правых отделах толстой кишки является фактором риска фрагментации опухоли и конверсии в резекцию толстой кишки.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>AIM</title><p>AIM: to assess results of endoscopic submucosal dissection (ESD) for colon neoplasms due to lesion site.</p></sec><sec><title>PATIENTS AND METHODS</title><p>PATIENTS AND METHODS: One-hundred thirteen patients (66 females, aged 65,7±11,0 years) with colon neoplasms which underwent ESD for one year (January 2017 – January 2018) were included in the study. All patients were divided in two groups depending on lesion site. The first group included patients with lesions in caecum, ascending colon and proximal third of tranverse colon, the second group – other colon parts and intraperitoneal part of the rectum. All patients underwent preoperative tests including colonoscopy, gastroscopy and transabdominal ultrasound. ESD included lesion marking, injection, circular incision and dissection. The results obtained were analyzed statistically using Graph Pad 7 for Mac. RESULTS: the 1st group included 61 (54.0%) patients and the 2nd – 52 (46.0%). Laterally spreading tumors (LST) were detected more often in the 1st group (56 patients of the 1st group vs 38 – in the 2nd, p=0.03). The lesion size in the 1st group was 31±13 (7-80) mm and 29±11 (8-76) in the 2nd one (p=0.3). Conversion from ESD to resection occurred in 9 (8.0%) patients, in 5 patients of the 1st group and in 4 – the 2nd one (p=1.0). The only reason for conversion was unfavorable lesion lifting (≤2 mm).</p><p>Most of the lesions were removed en bloc, specimen fragmentation after ESD occurred in 10 (9.6%) patients: in 5 (9.0%) in the 1st group and in 5 (10.4%) in the 2nd (р=1.0). Intraoperative complications during ESD in the 1st group occurred in 2 (3.5%) cases and in 2 (4.1%) – in the 2nd (р=1.0). Postoperative complications were detected in 2 (1.9%) patients. Histopathology showed adenocarcinoma in 9 (8.0%) patients. Two (1.7%) patients produced local recurrence. CONCLUSION: ESD is a safe method removal of colon ademonas. The intra- and postoperative complications rate is 3.5% and 1.9% for the 1st and the 2nd group. Local recurrences occurred in 2,04%. Unfavorable lesion lifting (≤2 mm) in right colon is a risk factor for specimen fragmentation or conversion.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>эндоскопия</kwd><kwd>диссекция в подслизистом слое</kwd><kwd>правый и левый отделы ободочной кишки</kwd><kwd>новообразования</kwd><kwd>аденокарцинома</kwd><kwd>фрагментация опухоли</kwd><kwd>рецидив опухоли</kwd></kwd-group><kwd-group xml:lang="en"><kwd>endoscopy</kwd><kwd>endoscopic submucosal dissection</kwd><kwd>colon</kwd><kwd>neoplasms</kwd><kwd>adenocarcinoma</kwd><kwd>lesion</kwd><kwd>piecemeal resection</kwd><kwd>local recurrence</kwd><kwd>right part of the colon</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., Майновская О.А., Рыбаков Е.Г.
