Abstract

Background: Endoscopic ultrasound–guided cystogastrostomy has become the first-line treatment for symptomatic peripancreatic fluid collections. The aim of this study is to analyze the efficacy and safety of cystogastrostomy via a meta-analysis of the literature. Methods: We performed a systematic search of PubMed and Medline databases for studies published from January 2005 to May 2018. We included randomized controlled trials along with retrospective and prospective observational studies reporting endoscopic ultrasound–guided cystogastrostomy stent placement for peripancreatic fluid collections. The primary outcome for our meta-analysis was complete peripancreatic fluid collection resolution on imaging. Our secondary outcomes included comparative efficacy and safety of the procedure for pseudocysts and walled-off pancreatic necrosis using metal and plastic stents. Results: Seventeen articles involving 1708 patients met our inclusion criteria for meta-analysis. Based upon the random effects model, the pooled technical success rate of cystogastrostomy was 88% (95% confidence interval = 83–92 with I 2 = 85%). There was no difference in the technical success rate between pancreatic pseudocysts and walled-off pancreatic necrosis (91% and 86%, respectively p = nonsignificant). The adverse event rates for metal and plastic stents were equivalent (14% and 18%, respectively, p = nonsignificant). Conclusion: Endoscopic ultrasound–guided cystogastrostomy stents are effective in the treatment of pancreatic pseudocysts and walled-off pancreatic necrosis. We found no difference in technical success or adverse event rates of drainage based on peripancreatic fluid collection type or stent used.
