Патоморфологическое исследование трансплантатов толстой кишки и желудочной трубки при эзофагопластике

Abstract

Представлены результаты патоморфологического анализа трансплантатов толстой кишки и желудочной трубки у 88 пациентов, перенесших эзофагопластику по поводу доброкачественных заболеваний пищевода. Установлено, что в отдаленный период после пластики трансплантат толстой кишки подвергается развитию гипотонии и деформации, в слизистой оболочке ведущими изменениями являются дистрофия и пролиферация эпителия с гиперплазией и гиперсекрецией бокаловидных клеток, лимфоплазмоцитарная инфильтрация интерстиция. В желудочной трубке часто формируются стенозы эзофагогастроанастомоза и очаги атрофии, в слизистой оболочке доминируют дистрофия и гиперсекреция фовеолярного эпителия, редукция фундальных желез, гипертрофия гладкомышечных компонентов, склероз стромы. Выявленные структурные модификации трансплантатов свидетельствуют о неоднотипном характере компенсаторно-приспособительных реакций слизистой оболочки толстой кишки и желудочной трубки в условиях эзофагопластики, дестабилизация которых может ассоциироваться с формированием патологических состояний искусственного пищевода.

The article presents the results of pathomorphological analysis of colon and gastric tube transplants in 88 patients after esophagoplasty for benign esophageal disease. It has been determined that colon transplant exposes hypotonia and deformation in long follow-up, the leading changes in mucosa are epithelial dystrophy and proliferation, goblet cell hyperplasia and hypersecretion, lymphoplasmacytic interstitial infiltration. In gastric tube the stenoses of esophagogastroanastomosis and atrophy centers are formed frequently. Foveolar epithelial dystrophy and hypersecretion, fundic gland reduction, smooth component hypertrophy and stromal sclerosis are dominate in gastric tube mucosa. The revealed structural updatings of investigated transplants reflect the heterogenic compensatory adaptation reactions of colon and gastric tube transplants mucosa after esophagoplasty. The destabilization of these reactions can be associated with origination of pathological states of an artificial esophagus.
