Over the course of the past 20 years, there has been a progressive increase in the number of publications pertaining to endoscopic ultrasonography. Large-scale prospective studies are now needed to validate earlier reports. In addition, the diagnostic and therapeutic role of endoscopic ultrasound needs to be more widely publicized among physicians in all health-care fields, so that appropriate patients may be referred.
External pancreatic fistulas may follow abdominal surgery or injury. While most respond to conservative management or endoscopic intervention, others might require surgery for complete healing. We report four cases of patients with external pancreatic fistulas that failed to respond to conservative management and drainage. N-butyl-2-cyanoacrylate surgical glue (Glubran 2) was directly injected into the fistulous tract. The fistulas closed within 24 hours of the Glubran 2 injection in three cases (75 %). In patients with external pancreatic fistulas that fail to respond to conservative and endoscopic drainage, injection of Glubran 2 directly into the fistulous tract may lead to closure, thus avoiding the need for surgical intervention.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
