[Treatment of pancreatic pseudocysts with ultrasound-guided percutaneous puncture and drainage].

The authors have treated 37 pancreatic pseudocysts in 36 patients by ultrasonically guided percutaneous puncture and drainage. The indication for intervention was rapid enlargement or threatening rupture of the acute (younger than 6-8 weeks) pseudocysts with recurring fever in 5 cases and chronic pseudocysts causing abdominal symptoms in 32 cases. After puncture six of seven patients were recuperated, but later in three of them the pseudocysts recurred. In one case as a complication of the puncture the pancreatitis exacerbated and led to death of the patient. The outcome of percutaneous drainage was successful in 26 of 32 pseudocysts. During the follow-up (6-54 months) recurrence were observed without symptoms in three cases. In four patients the treatment was ineffective, therefore cystogastrostomy was performed. During the time of the percutaneous drainage two pseudocysts had been infected and abscesses developed, which were treated by oncotomy. On the basis of their favourable experiences the authors recommend the US-guided percutaneous durable drainage as primer intervention for treatment of the pancreatic pseudocysts causing symptoms.
