Background: Stenosis of the pancreaticojejunostomy is a well-known long-term complication of pancreaticoduodenectomy. Traditionally, the endoscopic approach consisted of endoscopic retrograde pancreatography (ERP). Endoscopic ultrasound (EUS)-guided intervention has emerged as an alternative, but the success rate and adverse event rate of both treatment modalities are poorly known. We aimed to compare the outcome data of both interventions.
Methods: We performed a systematic literature search using the Pubmed/Medline and Embase databases in order to summarize the available data regarding efficacy and complications of ERP- and EUS-guided pancreatic duct (PD) drainage and compare these outcome data using uniform outcome measures in a multilevel logistic model. RESULTS : 13 studies were included, involving 77 patients who underwent ERP-guided drainage, 145 who underwent EUS-guided drainage, and 12 patients who underwent both modalities. An EUS-guided approach was significantly superior to an ERP-guided approach with regard to pancreatic duct opacification (87 % vs. 30 %; P < 0.001), cannulation success (79 % vs. 26 %; P < 0.001), and stent placement (72 % vs. 20 %; P < 0.001). An EUS-guided approach also appeared superior with regard to clinical outcomes such a pain resolution. The adverse event rate between the two treatment modalities could not be compared due to insufficient data. All included studies were found to be of low quality.
Conclusion: Based on limited available data, EUS-guided PD intervention appears superior to ERP-guided PD intervention.
