Purpose of the study. The role of interventional methods of the treatment of acute infected necrotic pancreatitis depending on the morphological characteristics of the disease was determined.
Material and methods. In present prospective cohort study, we included 96 patients with acute infected necrotizing pancreatitis. All patients were stratified according to morphologic features. Stepup approach with following steps of interventions was applied: percutaneous drainage of infected fluid collections, increasing of drainages diameter and number of it and open or minimally invasive necrosectomy. Clinical, laboratory, and instrumental monitoring were the defining indicators for the stopping of the treatment or for the passing to the next step of the treatment.
Results. At the first step 7 of 96 patients with superficial focal necrosis, a necrosis index of 2 points and a category D were successfully treated. Other 89 patients were passed to the second step of treatment, of which 23 patients with superficial subtotal necrosis, necrosis index of 2 points and category E were successfully treated. Another 66 patients had undergone a third step of treatment. A multivariate regression analysis was conducted that allowed to identify predictive factors of inefficiency of using of percutaneous drainage interventions (stages I and II) as a final stage of treatment: transmural subtotal or total necrotizing pancreatitis (OR = 1,58; 95% CI 1,03–3,88; p = 0,033); Necrosis index of 4 or more points (OR = 3.19, 95% CI 1.57–8.37; p = 0,003); heterogeneous peripancreatic fluid collection (OR = 4,15, 95% CI 1,49–5.19; p = 0,001); The CT-index of severity of acute pancreatitis of 7 or more points (OR = 1,89, 95% CI: 1,03–3,43; p = 0,029).
Conclusion. Step-up approach showed following results: 7,3% patients were treated at the first step, 24% – at the second step. Third step of treatment was applied in 68,7% of patients, of witch 12,5% was treated with laparoscopic necrosectomy. Predictors of ineffectiveness of ultrasound guided percutaneous drainage as the final treatment method are: necrosis index of 4 or more, heterogeneous paripancreatic fluid collections, subtotal and transmural necrotizing pancreatitis.
