Management of XXXX .

@entity1 @entity9007
Between 1969 and 1987, 68 @entity1 with @entity9007 were treated. The median cyst size was 10 cm (range 2-25 cm). Nine @entity1 were managed conservatively with resolution of the @entity9007 in eight @entity1 . These @entity1 had significantly smaller (median 4 cm) cysts compared with those in both percutaneously and surgically treated @entity1 (P less than 0.01). In 22 @entity1 the @entity9007 (median 9 cm) were punctured percutaneously under ultrasound guidance and the cyst fluid was aspirated or drained through a catheter. Complete resolution occurred in 13 @entity1 after 1-4 (mean 1.8) punctures per @entity1 , regression occurred in six @entity1 after 1-4 (mean 2.0) puncture procedures per @entity1 and three were unchanged. No complications were noted, except that two @entity1 treated percutaneously required additional surgery. Thirty-seven @entity1 were managed surgically (median cyst size 11 cm) with external drainage (12 @entity1 ), cystgastrostomy (17 @entity1 ), cystduodenostomy (three @entity1 ) cystjejunostomy (three @entity1 ) and pancreatic resection (two @entity1 ). Resolution of the cyst was noted in 29 @entity1 , regression in five and three were unchanged. Five @entity1 required additional surgery. Twelve complications were seen in ten @entity1 (27 per cent), most frequently after external drainage. One @entity1 died after surgical treatment. Mean hospital stay was 13 days among @entity1 treated conservatively and 30 days in both percutaneously and surgically treated @entity1 . Aspiration or catheter drainage of pseudocyst fluid guided by ultrasonography seems a safe and effective treatment of @entity9007 and should be considered as initial therapy. If surgery is required cystgastrostomy is preferred.
