We describe placement of a double pigtail cystogastric stent in 5 patients with pancreatic pseudocyst using real-time ultrasonography and fluoroscopy as guidance techniques. This was done as a two-step procedure. First, a transgastric drainage catheter was placed for a period of six days. All the patients continued to have high drainage output and the cyst size decreased, as seen sonographically. Simultaneous barium meal and sinogram were then done to measure the distance between the posterior gastric wall and the cyst. A polyurethane double pigtail stent of appropriate size was then introduced to achieve cystogastric drainage. The cyst resolved in all the patients by four weeks to six weeks, when the stent was removed endoscopically. There was no recurrence of pseudocyst during follow-up for 6 months to 13 months. None of the patients suffered any complication. Cystogastric drainage using a double pigtail stent is an easy and safe alternative to surgical cystogastrostomy.
