Techniques of ERCP with a conventional endoscope in pancreatoduodenectomy anatomy

We read with interest the article by Chen et al1 on the study comparing EUS-guided pancreatic duct drainage (EUS-PDD) with enteroscopy-assisted endoscopic retrograde pancreatography (e-ERP) in pancreatoduodenectomy anatomy. Technical success was achieved in 92.5% of cases (EUS-PDD) and 20% of cases (e-ERP) (P < .001). In e-ERP, the reasons for technical failure included failed cannulation (42.9%), inability to identify the pancreatojejunostomy (35.7%), and inability to reach the pancreatojejunostomy (21.4%).
