Safety and Efficacy of Fully Covered Self-Expandable Metal Stents for Benign Upper Gastrointestinal Strictures Beyond the Esophagus

Background Stents utilized for pyloric, duodenal, or anastomotic malignant strictures are generally uncovered and are not retrievable. Taewoong Medical created a through-the-scope stent that is fully covered, retrievable, and can be placed beyond the esophagus for benign gastroduodenal strictures as...

description Background Stents utilized for pyloric, duodenal, or anastomotic malignant strictures are generally uncovered and are not retrievable. Taewoong Medical created a through-the-scope stent that is fully covered, retrievable, and can be placed beyond the esophagus for benign gastroduodenal strictures as an alternative to surgical approaches. The aim of this paper is to examine the safety and efficacy of short-term, fully covered, self-expanding metal stents (FC-SEMS) in refractory benign strictures of the pylorus, duodenum, and gastrojejunal anastomosis. Methodology This multicenter case series was conducted at four hospitals from January 2018 through December 2020. Patients presenting with benign strictures of the pylorus, duodenum, or gastrojejunal anastomosis were entered into the study. A therapeutic channel scope was utilized to place FC-SEMS to open strictures. The stents were removed a few weeks later. A four-point gastric outlet obstruction scoring system (GOOSS) was used to record improvement. Results Statistically significant improvement in GOOSS was found between the pre-procedure and the four-week follow-up. Conclusions Fully covered, retrievable metal stents appear safe and effective in the management of refractory benign pyloric, duodenal, and anastomotic strictures. This may provide a less invasive option in the management of these strictures compared to surgery.
