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

World J Clin Cases. 2018 Oct 6;6(11):459-465. doi: 10.12998/wjcc.v6.i11.459.


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 EUS-guided 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 EUS-guided drainage of PPC. To our knowledge, this method has not been previously reported.
