Percutaneous Interventions in Patients with Pancreatic Pseudocysts
Aim. Analysis of the outcomes in patients with pancreatic pseudocysts who underwent percutaneous puncture-draining interventions. Material and Methods. Minimally invasive percutaneous interventions were used in 164 patients with chronic pancreatic pseudocysts. The cause of pancreatic pseudocysts was severe acute pancreatitis 0.5-5 years ago. Cystic dimensions ranged from 4 to 20 cm. Multiple cysts were observed in 17 patients. 17 patients (10.4%) had purulent pseudocysts, in 30 (18.3%) patients clinical symptoms of cystic compression were presented. Indications for surgery were diameter over 5 cm, signs of compression, infection, pancreatic hypertension. Results. Percutaneous techniques were effective in 155 (94.5%) patients. In 110 patients the cysts successfully regressed after percutaneous drainage and conservative therapy. Mortality was absent. Puncture was applied in 54 patients with good effect in 29 of them. Percutaneous drainage followed by elective sanations was effective in 10 patients with purulent pseudocysts. In 22 of 30 patients with clinical signs of compression puncture-draining operations were successful. In 8 patients endobiliary drainage was made additionally, in 19 cases nasointestinal probing for nutritional support and bile return was applied. Conclusion. The results show high efficiency of percutaneous minimally invasive techniques in chronic pancreatic pseudocysts management. So, they are considered as the main and final methods of treatment for these patients.
