Background. The increase in the number of patients with postnecrotic pancreatic cysts is explained by restrained wait-and-see tactics in the treatment of acute pancreatitis. Now, there are no treatment tactics and choice of surgical methods for treating patients with this pathology. The purpose of the research is to study the structure of complications after the use of minimally invasive interventions in patients with postnecrotic pancreatic cysts. Materials and methods. The study included 109 patients with postnecrotic pancreatic cysts who underwent minimally invasive interventions under ultrasound guidance. In 68.8 % of cases, the use of minimally invasive interventions in such patients was used as the final stage of surgical treatment, in other cases (31.2 %) - as the first stage of surgical treatment. At the second stage, traditional surgical interventions were performed. The size of pancreatic cysts, their topical affiliation, wall formation, connection with the pancreatic ductal system, and the nature of the contents were determined using a modern range of various diagnostic methods. Results. After percutaneous puncture of a postnecrotic pancreatic cyst under ultrasound control, complications developed in 27.3 %, after percutaneous external drainage under ultrasound control - in 16.5 %, after percutaneous transgastric externalinternal drainage under ultrasound control - in 23. 1 %. Conclusions. The use of puncturedrainage operations under ultrasound control in the treatment of patients with postnecrotic pancreatic cysts in 18.3 % of cases is accompanied by postoperative complications. These complications can be treated quite easily conservatively or with the use of minimally invasive interventions.
