Balloon dilator controls massive bleeding during endoscopic ultrasound-guided drainage for pancreatic pseudocyst:A case report and review of literature

摘要

Pancreatic pseudocyst(PPC),a common sequela of acute or chronic pancreatitis,was defined by the revised Atlanta classification as“a collection.”Endoscopic ultrasound(EUS)-guided drainage is often considered a standard first-line therapy for patients with symptomatic PPC.This effective approach exhibits 90%-100%technical success and 85%-98%clinical success.Bleeding is a deadly adverse event associated with EUS-guided drainage procedures,and the bleeding rate ranges from 3%to 14%.Hemostasis involves conservative treatment,endoscopy,interventional radiology-guided embolization and surgery.However,few studies have reported on EUSguided drainage with massive,multiple hemorrhages related to severe pancreatogenic portal hypertension(PPH).Thus,the aim of this case report was to present a case using a balloon dilator to achieve successful hemostasis for PPH-related massive bleeding in EUSguided drainage of PPC.To our knowledge,this method has not been previously reported.
