В исследование включено 38 больных кистозной трансформацией желчных протоков 25–75 лет (средний возраст 41,1 ± 13,5 года). Мужчин было 6 (16%), женщин – 32 (84%). Объем обследования пациентов на дооперационном этапе: УЗИ, КТ, МРТ, ЭРХПГ. Все пациенты были оперированы.</p></sec><sec><title>Результаты</title><p>Результаты. Первую группу составили 17 (44,7%) пациентов, у которых заболевание было выявлено впервые, во вторую группу включили 21 (55,3%) пациента, перенесшего ранее различные вмешательства по поводу кист желчных протоков. Практически во всех наблюдениях кистозная трансформация не была ликвидирована, что в дальнейшем вновь привело к появлению жалоб. Полученные результаты позволили исключить из алгоритма КТ, тем самым сократить время обследования и уменьшить его стоимость. Наиболее эффективный алгоритм выявления кистозной трансформации желчных протоков включает УЗИ, МРТ и МРХПГ с гепатоспецифичным препаратом. Указанные методы удовлетворяют все потребности в диагностике кист желчных протоков и позволяют установить диагноз практически в 98–100% наблюдений.</p></sec><sec><title>Заключение</title><p>Заключение. Оценка кистозной трансформации желчных протоков должна включать тип кисты по T. Todani, состояние ее стенок и содержимого, синтопию с окружающими структурами и изменения в них. Это имеет значение в том числе и для выбора правильного способа оперативной коррекции. Указанные данные необходимо получить на дооперационном этапе. Принципиально важно начинать обследование с неинвазивных методов. Высокий риск развития осложнений в отдаленном послеоперационном периоде, а также малигнизация кист свидетельствуют о необходимости наблюдения за пациентами, перенесшими оперативные вмешательства. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To evaluate the role of radiological methods in diagnosis and differential diagnosis of cystic transformation of bile ducts and monitoring of operated patients.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. The study included 38 patients with cystic transformation of bile duct aged 25–75 years (mean 41.1 ± 13.5 years). There were 6 (16%) men and 32 (84%) women. Preoperative survey included ultrasound, CT, MRI, ERCP. All patients were operated.</p></sec><sec><title>Results</title><p>Results. All patients were divided into 2 groups: group 1 consisted of 17 (44.7%) patients with primary disease, group 2 – 21 (55.3%) patients with previous surgery for biliary cysts. Cystic transformation was not eradicated almost in all cases that resulted symptoms in remote period. Computed tomography was excluded from the diagnostic algorithm in view of these data. Therefore, cost and time of examination were reduced. The most effective diagnostic protocol for cystic transformation of bile duct includes ultrasound, contrast-enhanced MRI. These methods cover all necessary diagnostic spectrum and define the diagnosis in almost 98–100% of cases.</p></sec><sec><title>Conclusion</title><p>Conclusion. An assessment of cystic transformation of bile ducts should include following parameters: cyst type by T. Todani classification, state of its wall and content, relationship with surrounding organs and their structural changes. These parameters are important to choose the right surgical approach. These data should be obtained at preoperative stage. It is essential to begin a survey from non-invasive methods. High risk of long-term postoperative complications and malignant transformation indicates the need for dynamic monitoring of patient after surgery. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>печень</kwd><kwd>желчные протоки</kwd><kwd>кистозная трансформация</kwd><kwd>УЗИ</kwd><kwd>МСКТ</kwd><kwd>МРТ</kwd><kwd>ЭРХПГ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>liver</kwd><kwd>bile ducts</kwd><kwd>cystic transformation</kwd><kwd>ultrasound</kwd><kwd>CT</kwd><kwd>MRI</kwd><kwd>ERCP</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">Милонов О.Б., Гуреева Х.Ф.
