Демонстрация возможности успешного удаления субэпителиального новообразования прямой кишки способом эндоскопической подслизисто-межмышечной диссекции (ЭПМД). У пациента 50 лет при колоноскопии в отделении эндоскопической диагностики и хирургии в среднеампулярном отделе прямой кишки определялось субэпителиальное новообразование размером до 0,5 см в диаметре, желтоватого цвета, слизистая оболочка над новообразованием не изменена. При инструментальной пальпации образование трудно смещалось, плотной консистенции, симптом «шатра» и «подушки» были отрицательными. Была выполнена ЭПМД. Послеоперационный период протекал без особенностей, пациент выписан на 5 сутки после операции. Морфологическое заключение: лейомиома собственной мышечной пластинки слизистой. Резецировано на уровне внутреннего мышечного слоя, края резекции интактны.

Demonstration of the possibility of successful removal of a subepithelial neoplasm of the rectum by endoscopic submucosal-intermuscular dissection (EPMD). In a 50-year-old patient, a colonoscopy in the department of endoscopic diagnostics and surgery in the middle ampullary rectum revealed a subepithelial neoplasm up to 0.5 cm in diameter, yellowish in color, and the mucous membrane above the neoplasm was unchanged. On instrumental palpation, the formation was difficult to shift, of a dense consistency, and the symptoms of a “tent” and “pillow” were negative. EPMD was performed.

The postoperative period was uneventful, and the patient was discharged on the 5th day after surgery.

Morphological conclusion: leiomyoma of the intrinsic muscle plate of the mucosa. Resected at the level of the inner muscle layer, the edges of the resection are intact.
