Цель исследования: выявить и оценить возможности прогнозирования панкреатической фистулы после панкреатодуоденальной резекции на основании данных предоперационной компьютерной томографии (КТ). Материал и методы. В 2005 г. Международная рабочая группа по изучению панкреатических фистул (International Study Group on Pancreatic Fistula, ISGPF) разработала критерии градации панкреатических фистул на бессимптомные биохимические (Grade A) и клинически значимые (Grade B и С), требующие терапевтической (Grade A) или хирургической коррекции (Grade B и С). Данная классификация стала общепринятой и широко используется. Проведен анализ литературы, при котором учитывались только оригинальные англоязычные публикации после 2005 г, которые описывали возможности предоперационной количественной оценки плотности поджелудочной железы (ПЖ) с помощью КТ, а данные КТ сопоставлялись с результатами гистологического исследования ткани ПЖ. Работы с малыми выборками (10 пациентов) были исключены из анализа. Результаты. Критериям включения соответствовали 3 статьи, описывающие возможности КТ для оценки степени фиброза и жировой инфильтрации паренхимы ПЖ, в качестве факторов риска панкреатической фистулы. Выявлена статистически достоверная зависимость данных показателей и риска панкреатической фистулы. Заключение. Современные возможности Кт позволяют объективно судить о риске развития панкреатической фистулы и предоставляют хирургам возможность подобрать наиболее подходящую периоперационную тактику ведения пациента. Прогнозирование риска панкреатической фистулы и формирование гомогенных групп для клинических исследований позволят получать более достоверные результаты при анализе данных даже из разных источников, что, несомненно, повысит качество проводимых исследований.

Aim. To reveal and evaluate opportunities of preoperative computer tomography (CT) for pancreatic fistula (PF) prediction after pancreatoduodenectomy. Materials and methods. In 2005 International Study Group on Pancreatic Fistula (ISGPF) developed grading criteria for PF, including asymptomatic biochemical (Grade A), that could be treated conservatively, and clinically relevant (Grade B, Grade C), with consecutive active surgical treatment. For now ISGPF definition of PF is widely accepted. We review the literature since 2005 for original articles in English describing quantitive assessment of the pancreatic parenchyma using CT with histological validation. Low sample trials (10 cases) were excluded. Results. Three original publications met the inclusion criteria. Fatty and fibrosis infiltration of the pancreatic parenchyma assessed by preoperative CT revealed statistically significant correlation with PF rate. Conclusion. Preoperative CT offers accurate prediction opportunities for postoperative pancreatic fistula and may help caregivers to set up protocols for a strict and early detection of warning clinical signs, to tailor the clinical management of different risk classes, or to select high-risk patients who might be excluded from surgical resection. This would also improve patient selection for relevant research protocols and facilitate a more definitive assessment of collected data related to surgical outcomes, across different institutions and surgeons, and even among different surgeries, in either single-institution or multi-centre trials that involve pancreatic surgery.
