Objective. To analyze the most well-known studies devoted to completion pancreatectomy (CP) for postoperative complications after pancreatoduodenectomy. Material and methods. We analyzed original articles and reviews between 1992 and 2023 (number of patients ≥5 (5—120)). Results. Mean blood loss in CP ranged from 500 to 2180 ml, surgery time — from 144 to 340 min. Along with standard postoperative complications (fluid collection, abscesses, bile leak and bleeding), patients had high risk of venous gastric congestion. The incidence of relaparotomies ranged from 7% to 63% with postoperative mortality up to 64%. Conclusion. A new clinical entity (fulminant necrotizing pancreatitis) as an absolute indication for CP will adjust surgical tactics and contribute to differential analysis of treatment outcomes in this category of patients.
