    Abstract:
    The purpose of this study was to evaluate the success of percutaneous transgastric cystgastrostomy as a single-step procedure. We performed a retrospective analysis of single-step percutaneous transgastric cystgastrostomy carried out in 12 patients (8 male, 4 female; mean age 44 years; range 21-70 years), between 2002 and 2007, with large symptomatic pancreatic pseudocysts for whom up to 1-year follow-up data (mean 10 months) were available. All pseudocysts were drained by single-step percutaneous cystgastrostomy with the placement of either one or two stents. The procedure was completed successfully in all 12 patients. The pseudocysts showed complete resolution on further imaging in 7 of 12 patients with either enteric passage of the stent or stent removal by endoscopy. In 2 of 12 patients, the pseudocysts showed complete resolution on imaging, with the stents still noted in situ. In 2 of 12 patients, the pseudocysts became infected after 1 month and required surgical intervention. In 1 of 12 patients, the pseudocyst showed partial resolution on imaging, but subsequently reaccumulated and later required external drainage. In our experience, percutaneous cystgastrostomy as a single-step procedure has a high success rate and good short-term outcomes over 1-year follow-up and should be considered in the treatment of large symptomatic cysts.
