Which indications and kind of drainage in case of severe acute pancreatitis?

Abstract

Definition of severe acute pancreatitis includes organ failure or/and pancreatic or peripancreatic fluid collections. Three types of emergency drainage can be discussed in such a situation: Biliary drainage by early endoscopic sphincterotomy, transpapillary endoscopic drainage in case of early pancreatic fistula, and peripancreatic fluid collections drainage using four different approaches (percutaneous radiologic drainage, retroperitoneal drainage by surgical laparoscopy, transgastric or transduodenal endoscopic drainage and open surgical necrosectomy). The purpose of this mini-review is to focus on the current indications and choices of these different types of drainage approach.
