В настоящее время в комплексной терапии пациентов с неоперабельными стадиями внепеченочной холангиокарциномы рекомендовано использование фотодинамической терапии (ФДТ), что достоверно увеличивает продолжительность жизни в сравнении с изолированной паллиативной терапией.Описание клинического случая: Представленный клинический случай демонстрирует успешное применение ФТД у пациентки с холангиокарциномой бифуркации общего печеночного протока T4N1M1, Bismuth-IV в сочетании с наружным дренированием желчных протоков с целью разрешения механической желтухи.Заключение: Показан значительный эффект ФТД у пациентки с неоперабельной опухолью Клацкина. Применение ФТД увеличивает продолжительность жизни в сравнении со средней выживаемостью на фоне проведения паллиативной терапии.</p></abstract><trans-abstract xml:lang="en"><p>Klatskin tumor is a perihilar cholangiocarcinoma of the lobar and common hepatic ducts (liver port cancer) which is localized proximally to the confluence of common hepatic and cystic ducts (before segmental hepatic ducts of the second order). Currently, photodynamic therapy (PDT) is recommended for the complex management of patients with inoperable extrahepatic cholangiocarcinoma because the discussed PDT technique significantly increases the life expectancy in comparison to the isolated palliative therapy.A clinical case presented in the article demonstrates the effectiveness of PDT technique in case of cholangiocarcinoma of bifurcation of the common hepatic duct T4N1M1, Bismuth-IV in combination with external drainage of bile ducts in order to resolve the mechanical jaundice.Conclusion. A significant effect of PDT application in a patient with inoperable Klatskin tumor is demonstrated. PDT included into the treatment of such patients increases their life expectancy versus the average survival rate in those having palliative therapy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Клинический случай</kwd><kwd>фотодинамическая терапия</kwd><kwd>внепеченочная холангиокарцинома</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Сase report</kwd><kwd>extrahepatic cholangiocarcinoma</kwd><kwd>photodynamic therapy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы выражают признательность ГБУЗ МО МОНИКИ им.
