Clinical outcomes of surgery for patients with chronic pancreatitis (CP), considering low rates of 10-year survival, are often unsatisfying for surgeons. Due to the absence of common diagnostic criteria, especially at an early stage of the disease, patients of young and working age undergo surgery at different periods and with different methods. The development of optimal criteria for the selection of diagnostic signs of chronic pancreatitis will improve treatment outcomes.The aim of the study is 1) to perform a comparative assessment of the informative value of methods that specify diagnostics of CP with obstruction of the main pancreatic duct; 2) to develop criteria for the selection of diagnostic signs to highlight the main types of structural changes in the pancreas in chronic pancreatitis with obstruction of the main pancreatic duct.Materials and methods. The study included radiological findings of 231 patients with CP with obstruction of the main pancreatic duct operated from 1996 to 2018 in Omsk regional surgical hospital. X-ray investigations were performed in 120 patients, ultrasound investigations were performed in 231 patients, multislice spiral computed tomography (MSCT) was performed in 226 patients, MRI was performed in 18 patients, endoscopic retrograde cholangiopancreatography (ERCP) was performed in 22 patients and angiography was performed in 5 patients. All patients were divided into two groups: control (n ​​= 88, until 2008) and case (n = 143, after 2008), where new methods of surgery were used and the structure of the applied diagnostic methods has been changed.Results. Ultrasound sensitivity was 74.5%, fistulography/virsungography sensitivity was 80%, MSCT sensitivity was 97.8%, MRI sensitivity was 88.9% and ERPC sensitivity was 95.5%. The use of invasive diagnostic methods in the main group of patients was minimized with the priority of MSCT. The main criteria for the selection of diagnostic signs of CP were determined as follows: obstruction of the main pancreatic duct (with localization at the level of the pancreatic head exclusively or along its entire length), dilatation of the main pancreatic duct (more than 3 mm), local damage to the pancreatic head with an increase in its size over 32 mm, cystic formations (more than 5 mm) in the projection of any part of the pancreas. The main types of structural changes in the pancreas were identified as follows: 1. CP with obstruction of the main pancreatic duct at the level of the pancreatic head exclusively; 2. CP with obstruction of the main pancreatic duct along its entire length with an increase in the size of the pancreatic head; 3. CP with obstruction of the main pancreatic duct along its entire length without an increase in the size of the pancreatic head.Conclusion. 1) MSCT has the highest sensitivity in CP diagnostics (98.6%). MRI (Magnetic Resonance Cholangiopancreatography (MRCP)) complements MSCT and replaces it in case of patient’s intolerance to contrast media. Indications for ERCP should be minimized. 2) The designed criteria for the selection of diagnostic signs of CP will optimize diagnostics of chronic pancreatitis with obstruction of the main pancreatic duct and highlight the main types of structural changes in the pancreas, the fact being important for validation of surgical treatment methods and techniques.</p></abstract><trans-abstract xml:lang="ru"><p>Обоснование. Результаты хирургического лечения больных хроническим панкреатитом (ХП), учитывая низкие показатели 10-летней выживаемости, не всегда удовлетворяют хирургов. Больные молодого и трудоспособного возраста оперируются в различные сроки и в объёме различных методов ввиду отсутствия единых диагностических критериев, особенно на ранней стадии заболевания. Разработка оптимальных критериев отбора диагностических признаков хронического панкреатита позволит улучшить результаты лечения.Цель. 1) провести сравнительную оценку информативности методов, уточняющих диагностику ХП с нарушением проходимости главного панкреатического протока. 2) разработать критерии отбора диагностических признаков для выделения основных типов структурных изменений в поджелудочной железе при хроническом панкреатите с нарушением проходимости главного панкреатического протока.Материалы и методы. Анализированы результаты методов лучевой диагностики 231 больного ХП с нарушением проходимости главного панкреатического протока, оперированного с 1996 по 2018 гг. в хирургическом стационаре БУЗ Омской области «ОКБ». Рентгенологические исследования проведены 120 больным, УЗИ - 231, МСКТ - 226, МРТ – 18, ЭРХПГ – 22 и ангиография - 5. Все обследованные разделены на две группы: сравнения (n=88, до 2008 г). и основную группу (n=143, после 2008 г.), где использовались новые способы хирургических операций и была изменена структура используемых методов диагностики.Результаты. Чувствительность УЗИ составила 74,5%, фистуло(вирсунго)графии – 80%, МСКТ – 97,8%, МРТ – 88,9% и ЭРПХГ – 95,5%. Использование инвазивных методов диагностики в основной группе больных было минимизировано с выделением приоритета МСКТ. Определены основные критерии отбора диагностических признаков ХП: нарушение проходимости главного панкреатического протока (с локализацией на уровне только головки поджелудочной железы или на всём протяжении), дилатация главного панкреатического протока (более 3 мм), локальное поражение головки поджелудочной железы с увеличением её размеров более 32 мм, кистозные образования (более 5 мм) в проекции любого отдела поджелудочной железы. Выделены основные типы структурных изменений в поджелудочной железе: 1. ХП с нарушением проходимости главного панкреатического протока на уровне только головки поджелудочной железы; 2. ХП с нарушением проходимости главного панкреатического протока на всём протяжении с увеличением размеров головки поджелудочной железы; 3. ХП с нарушением проходимости главного панкреатического протока на всём протяжении без увеличения размеров головки поджелудочной железы.Заключение. 1) Наибольшей чувствительностью в диагностике ХП (98,6%) обладает МСКТ. МРТ (МРХПГ) дополняет МСКТ и заменяет её в случаях непереносимости больными контрастных препаратов. Показания к ЭРХПГ должны быть минимизированы. 2) Разработанные критерии отбора диагностических признаков ХП позволят оптимизировать диагностику хронического панкреатита с нарушением проходимости главного панкреатического протока и выделить основные типы структурных изменений в поджелудочной железе, имеющие значение для обоснования методов и способов хирургического лечения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>chronic pancreatitis</kwd><kwd>main pancreas duct</kwd><kwd>pancreas head</kwd><kwd>ultrasonography</kwd><kwd>multispiral computerized tomography</kwd><kwd>magnetic resonance imaging</kwd><kwd>мagnetic resonance сholangiopancreatography</kwd><kwd>retrograde cholangiopancreatography</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>хронический панкреатит</kwd><kwd>главный панкреатический проток</kwd><kwd>головка поджелудочной железы</kwd><kwd>ультразвуковое исследование</kwd><kwd>мультиспиральная компьютерная томография</kwd><kwd>магнитно-резонансная томография</kwd><kwd>магнитно-резонансная холангиопанкреатография</kwd><kwd>эндоскопическая ретроградная холангиопанкреатография</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Jafri M, Javed S, Sachdev A.
