BackgroundIt seems that lumen-apposing metal stents (LAMS) are displacing plastic stents in the therapy of pancreatic-fluid collection in walled-off necrosis (WON). To date, there is no quality of evidence to recommend LAMS as the standard treatment in the management of WON. The theoretical benefit of LAMS over plastic stents needs to be proven.Methods/designThis is a randomized controlled, multicenter, prospective clinical trial with two parallel groups, without masking. One-hundred and fourteen patients with WON will undergo endoscopic ultrasound (EUS)-guided transmural draining in nine tertiary hospitals in Spain and will be randomized to the LAMS or plastic-stent group. The primary endpoint is the short-term (4 weeks) clinical success determined by the reduction of the collection (to < 50% or < 5 cm in size), along with clinical improvement. Secondary endpoints: long-term (4 months) clinical success (total resolution or 5 cm), procedure duration, level of difficulty, safety, and recurrences.DiscussionThe PROMETHEUS trial has been designed to determine whether LAMS are superior to plastic stents in EUS-guided transmural drainage of WON.Trial registrationClinicalTrials.gov, ID: NCT03100578.

Background: It seems that the appearance of lumen-apposing metal stents (LAMS), are displacing the role of plastic stents in the therapy of pancreatic fluid collection as walled-off necrosis (WON). To date there is no quality of evidence to recommend LAMS as the standard treatment in management of WON. The theoretical benefit of LAMS over PLASTIC stents, need to be proved.Methods/design: This is a multicenter prospective study, superiority, randomized controlled clinical trial by parallel groups, without masking. One hundred fourteen patients with WON will be Endoscopic ultrasound (EUS)-guided transmural drained in 9 tertiary hospitals in Spain and will be randomized to the LAMS or PLASTIC stent group. The primary endpoint is to assess the short-term (4 weeks) clinical success determined by the reduction of the collection (to <50% or < 5cm in size), along with clinical improvement. Secondary endpoints: the long-term (4 months) clinical success (total resolution or 5cm); the procedure’s duration, the level of difficulty, safety and recurrences.Discussion: The PROMETHEUS trial has been designed to response if LAMS are superior over PLASTIC stents in the EUS-guided transmural drainage of WON.

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.
