Experience of transmural endoscopic drainage in treatment of pancreatic pseudocysts

Objective. To evaluate the possibilities of transmural endoscopic drainage in treatment postnecrotic pancreatic pseudocysts immediate and long-term periods.
 Materials methods. From 2018 to 2022, a method was used 36 patients with at Perm Regional Clinical Hospital. The results were evaluated postoperative period, 47 months before removal stent 14 years by complaints patients, blood amylase content, ultrasound CT examination abdominal cavity.
 Results. Two-three days after intervention, cyst completely disappeared 30.56 % decreased half or more diameter 63.89 only 5.56 slightly. After years, absence cysts registered 80 %, small (from 15 24 mm) 10 %. Pancreatic persisted three (10 %). Statistical analysis showed that wider main duct higher level drainage, poorer result.
 Conclusions. Transmural makes it possible achieve complete disappearance significant reduction size year intervention 90 cases. clinical result depended on initial width amylase.
