title: Percutaneous cystogastrostomy with a new catheter for drainage of pancreatic pseudocysts and fluid collections.
abstract: We describe a new catheter for the initial percutaneous drainage of large symptomatic pancreatic fluid collections and abscesses using a transgastric approach to allow fluid drainage into the gastric lumen. A double-mushroom stent is placed secondarily for long-term internal drainage to the stomach, avoiding the need for an extended period of external catheter drainage. This technique, termed percutaneous cystogastrostomy (PCG), has been used in 19 consecutive patients with one recurrent symptomatic pseudocyst in the follow-up period fo 9-43 months. There was one death within 30 days of PCG and 1 patient proceeded to surgical necrosectomy. After evidence of resolution of the pseudocysts, the internal stent was retrieved in 17 patients by endoscopic snare.
