60 pancreatic pseudocysts are reported. 29 cystojejunostomies, 22 cystogastrostomies, 2 cystoduodenostomies and 7 external drainages were performed. Most favourable results could be recorded by cystojejunostomy. The total operative mortality was 8.3%, after cystojejunostomie 3.4%. Most dangerous complications were haemorrhage and peritonitis. In the follow up of internal operative drainage approximately 80% excellent or satisfactory results could be observed.

External drainage is indicated in emergency or development of complications.
