Abstract
Introduction: Biomedical devices implanted transabdominally have gained popularity over the past 50 years in the treatment of gastroesophageal reflux disease, paraesophageal hiatal hernia, and morbid obesity. Device-related foregut erosions (FEs) represent a challenging event that demands special attention owing to the potential of severe postoperative complications and death. Purpose: The aim was to provide an overview of full-thickness foregut injury leading to erosion associated with four types of biomedical devices. Methods: The study was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). PubMed, EMBASE, and Web of Science databases were queried until December 31, 2023. Eligible studies included all articles reporting data, management, and outcomes on device-related FE. Results: Overall, 132 articless were included for a total of 1292 patients suffering from device-related FE. Four different devices were included: the Angelchik antireflux prosthesis (AAP) (n = 25), nonabsorbable mesh for crural repair (n = 60), adjustable gastric banding (n = 1156), and magnetic sphincter augmentation device (n = 51). The elapsed time from device implant to erosion ranged from 1 to 480 months. Most commonly reported symptoms were dysphagia and epigastric pain, while acute presentation was reported rarely and mainly for gastric banding. The technique for device removal evolved from more invasive open approaches toward minimally invasive and endoscopic techniques. Esophagectomy and gastrectomy were mostly reported for nonabsorbable mesh FE. Overall mortality was .17%. Conclusions: Device-related FE is rare but may occur many years after AAP, nonabsorbable mesh, adjustable gastric banding, and magnetic sphincter augmentation implant. FE-related mortality is infrequent, however, increased postoperative morbidity and the need for esophagogastric resection were observed for nonabsorbable mesh-reinforced cruroplasty.
